So I am installing the Oracle client for the first time in my life (Yes, there are still some geek things I haven’t done yet) and wow was I surprised at the poor quality of the installer.
Here is the ugly:
1. I start the install and immediate a big black Command Prompt window comes up.
2. Once it comes up, it tries to install to a c:\app\jbarneck folder. Really? You haven’t figured out C:\Program Files\Oracle yet?
3. I installed only Instant Client. I needed Administrator as well. On reinstall it installed a new second instance of the Oracle Client. No it didn’t work and I have reverted my VM to try again.
4. When you have gone through their wizard and it is time to start the install, you click Finish. Yes, you heard correctly, you click Finish to start. When the install finishes, there is a small line of text letting me know it was successful and a close button.
5. Then I have to go get some text file called a .ORA file and copy it myself.
Anyway. If it was an Open Source project it wouldn’t be this poor. This is something I would have expected in the NT 4.0 days.
So if this is the lack of enterprise quality that I can expect from Oracle, which is a very rich “enterprise”, I will continue to stay away and recommend others do the same.
All I can say is: Wow, Oracle! Get your act together.

Ok, so as today, August 26, 2010, my blog is hosted by WordPress.com. It will be this way for some time.
However, I am probably going to eventually have my own server hosted somewhere. Probably with my brother’s company, Fusion Networks.
So I will probable build a FreeBSD server that will host my site. At this point, I think I will stop using WordPress and use a different Content Management System.
Content Management Systems Lists
So I went into this having done reasearch before, so I knew what I was getting into. There are plenty of different Content Management Systems and unfortunately there is no way I could find time to test them all.
Ok, now that you have seen the very large list of Content Management Systems, you realize that I have to narrow my list down without really testing them all.
Narrowing down the list
First, let me document what I would like and see if which fit into the list. These are not in order of priority, and some are important and some are not.
I want it to
use PHP
have a large community
use a BSD License
use Postgresql (as it is BSD licensed and MySQL is not)
import my existing WordPress blog
have great feature sets
have common plugins
support multiple Blogs with one install
manages website as well as blog
manages multiple sites
have a descent editor
be well documenated
PHP-Based
They have their lists separated into tables by programming language. The PHP table has the most options and since I for sure want to use PHP, it is the only table I will focus on. These tables even lists the license.
So the big three Content Management Systems seems to be these. I don’t have any data to back this up. I think this is just because these three seem to be more mentioned when doing Google searches.
Drupal
Joomla
WordPress
BSD Licensed
However, none of those are BSD Licensed, which I prefer. I am not opposed to GPL or LGPL, but I feel more comfortable with BSD licenses software.
The Content Management Systems that are PHP-based and use the BSD License are these:
Had one of the Big 3 been BSD licensed, my decision would have probably been easy. However, obviously I am going to have to test some of the three BSD licensed Content Management Systems.
Supports Postgresql
Of the six Content Management Systems listed above, the following support Postgresql.
Drupal
Serendipity
SilverStripe
Can import my WordPress blog
It appears that they all can do this.
I am worried about links, however. My blog entries often link to each other. I question whether they do it perfectly. For example, a link to one of my WordPress blogs might be this:
So if I go with something other than WordPress, then after importing my blogs, are all the links going to be broken?
Making the Decision
So here is the rating, after a very small overview of the different CMS web sites, and before verifying their marketing claims.
I am giving 0 to 3 points for each feature. (This is subject to change over time, should I want to come back after the decision and report on something).

Here is what I am going to do:
I am going to build a BSD, Apache, PHP, Postgresl virtual machine and test Drupal and Serendipity to see how the import goes.
Perhaps I will have a follow-up some time because:
I have to test these different CMSes
I am sure there are a dozen other items that should be scored 1-3 that I haven’t thought of.
http://rhyous.wordpress.com/wp-admin/post.php?post=2212&action=edit&message=1
There was a FreeBSD port.
The install was painless.
Negatives
Their web site didn’t seem very good, which is a big turn off for a company that is a CMS.
The links to their Forum on their web site and other pages were broken. I did find that the forum does exist, so the links are just broken.
I tried to sign up for the Forum to report the broken links. I registered, but was supposed to be sent a confirmation email, which I never received, even after re-requesting it, so I have never reported the broken links. They are still broken a day later. Also, there appear to only be a handful of people on their forums at any given time. Both suggest they have a small community.
I couldn’t figure out how to design my home page. It seemed the blog was my home page. I couldn’t figure out how to move my blog entries to a different page.
Result
If you want one blog and nothing else, this would work for you.
I need more. I stopped trying and have dropped Serendipity from the list.
I looked at SilverStripe second and I way more pleased with its feature set.
Positives
Though I had some install problems, I found solutions on their forums.
There are a number of theme available for download.
The default web site had some common pages premade:
Home
About Us
Contact Us
Page not found
They had both Site Management and Blog management.
There are many extensions: modules, themes, widgets.
Modules include a Blog Modules and Sub-site module, so I could manage multiple sites and multiple blogs.
It is simple to download and install modules.
The user interface is simple and easy to use.
The documentation is sufficient.
Negatives
I had install/setup problems (that were resolved) by the Forum. Supposedly they only occur with Postgresql.
Not a lot is included in the default install.
The community is smaller than I would like.
The documentation is only sufficient.
Conclusion
I really like the SilverStripe interface.
It had almost everything I am looking for. It is BSD Licensed. It supports Postgresql.
It is a Content Management System first, and has modules to add to it. There a blog module, a multi-site module, which really interested me.
However, while it has a module to import a WordPress xml, I have yet to get it to work. That is something I can live with, but I would prefer it to work.
I almost feel like apologizing to Joomla. I had two BSD servers, one with FreeBSD, Apache, PHP, MySQL where I installed WordPress a year ago for testing. I have another brand new server with FreeBSD, Apache, PHP, and Postgresql where I tested all the postgresql capable CRMs. However, I installed Joomla to the wordpress server and it just didn’t work. The page was blank. I actually think there was a php error, not a Joomla error.
Unfortunately, Joomla doesn’t support postgresql, it isn’t BSD licensed. I did research and it appears like it would score high with WordPress, Drupal, and Silverstripe, but I can’t really see how it would be any better than Drupal, or Silverstripe so I really had to cut it loose. Lets be honest. As a BSD users, it was beaten out by Drupal and Silverstripe for the same reason I am looking to replace WordPress. It doesn’t support Postgresql.
Others
There are two other Content Management Systems that I feel are worth mentioning.
Django is also a CMS that is BSD licensed and supports Postgresql. However, it runs on Python, a language which I have occasionally touched but never really developed in. If you know Python, this might be the choice for you.
Bricolage is also a CMS that is BSD licensed and supports Postgresql. However, it runs on Perl, which I have written a few things with, but not as much as PHP. If you know Python, this might be the choice for you.
My Decision
I know, you all want to know which I chose to use.
Drumb roll please….
I have chosen…
But don’t expect my blog to move to Silverstripe tomorrow. It move slowly with things like this. It could take months or get delayed for a year.
Anyone who might choose a CMS differently would be completely happy with any of the others they evaluate and feel meets their needs. I am not saying I chose the best. I am saying I chose the best for my needs. Hopefully, you know your needs and this will help you choose the best Content Management System for your needs.
It is BSD Licensed instead of GPL, which is especially more attractive if you need to distribute the database software. In fact, if you are reselling a product, and paying a license fee to MySQL you probably should save your company the money and move to Postgresql. LANDesk, the company I work for, had just such an experience with our Management Gateway device.
As always, installing software on FreeBSD is simple using the ports system.
#
#
cd /usr/ports/databases/postgresql84-server
make WITH_OPTIMIZED_CFLAGS=true BATCH=yes install clean
Post-installation Setup
There a few post-installation steps.
Initialize the database
#
/usr/local/etc/rc.d/postgresql initdb
Or starting with FreeBSD 8.1, you can now run this command:
#
service postgresql initdb
Make any changes to the postgresql.conf
The postgresql.conf is located in /usr/local/pgsql/data.
Open the file and read through it and make any desired changes.
Common Changes
Here are two common changes.
Enabled remote connections
If the database is to be accessed by the network, then you should at least uncomment the setting #listen_addresses = 'localhost' and change it to listen_addresses = '*'.
Changing the default TCP Port
Uncomment the setting #port = 5432 and change the port number to the desired value.
Configure password authentication
Change to the /usr/local/etc/pgsql/data directory.
Edit the pg_hba.conf and change the default authentication method to something more secure, such as md5.
# TYPE DATABASE USER CIDR-ADDRESS METHOD# "local" is for Unix domain socket connections only
local all all md5
# IPv4 local connections:
host all all 127.0.0.1/32 md5
# IPv6 local connections:
host all all ::1/128 md5
Configure the postgresql server service to start on reboot
Add the string postgresql_enable="YES" to /etc/rc.conf.
#
echo ‘postgresql_enable=”YES”‘ >> /etc/rc.conf
Creating a Database
To create a database, su to pgsql and run createdb.
#
$
su pgsql
createdb MyDBName
Note: Similarly, use dropdb to drop a database.
Creating a User or Role
To create a user, su to pgsql and run createuser.
#
$
su pgsql
createuser -P
Enter name of role to add: MyUserOrRoleName
Enter password for new role:
Enter it again:
Shall the new role be a superuser? (y/n) y
If you are not using password authentication, then you can exclude the -P.
Using psql client
A simple way to connect to postgresql is using the shell-based client, psql.
Connecting
To connect, use the following command.
$
psql MyDBName
MyDBName-#
You are now at the psql prompt.
Connecting as a different user
To connect, use the following command.
$
psql MyDBName MyUserOrRoleName
MyDBName-#
You are now at the psql prompt.
Changing a a User or Role Password
To change a password, use the following syntax.
MyDBName-# alter role pgsql with password ‘pw’;
Show Databases
To show database, simply type \l, (which is the lowercase letter L not the number 1) which is short hand in psql for this query: SELECT datname FROM pg_database;
MyDBName-#
\l
Show Tables
To show tables in the current database, simply type \d, which is short hand in psql for this query: SELECT table_name FROM information_schema.tables WHERE table_schema = 'public';
MyDBName-#
\d
Show Tables
To show columns of a table in the current database, simply type \d table, which is short hand in psql for this query: SELECT column_name FROM information_schema.columns WHERE table_name ='table';

I have a DataColumn that contains an space and I just couldn’t get the DataTable.Select(“Column Name=value) function to work.
So i found a solution on some other guys wordpress blog here.
The answer should be obvious to those who use SQL. In SQL to use a space, it often adds square brackets around the column names. [Column Name]. Yes, using square brackets is the solution.
String colName = "Column Name";
String Value = "some data";
DataTable.Select("[" + colName + "]='" + value + "'");
The Northwind database is referenced online in sample code quite often. However, this renders the sample code useless to someone who doesn’t know what Northwind is or how to use it.
The Northwind database is basically just an example database that runs under SQL Server. This database is populated with data that represents an imaginary company’s sales data. It is a very common example database for SQL Server testing and sampling.
You might be wondering, what is SQL Server (though for your sake, I hope not). Well, SQL Server is Microsoft’s database software.
How do I know if SQL is installed?
If you have Visual Studio 2008 installed, you probably have SQL Server 2008 installed and you don’t even know it.
You can go to Add / Remove Programs and look for Microsoft SQL Server.
Or you can check for the services.
Or if you aren’t good with the GUI, you can open a command prompt and run this command to see if you have the SQL services:
C:\Users\UserName>
sc query state= all |findstr SQL |findstr DISPLAY_NAME
DISPLAY_NAME: SQL Server (SQLEXPRESS)
DISPLAY_NAME: SQL Active Directory Helper Service
DISPLAY_NAME: SQL Server Agent (SQLEXPRESS)
DISPLAY_NAME: SQL Server Browser
DISPLAY_NAME: SQL Server VSS Writer
If you don’t see the services ouptut, you don’t have SQL Server Express installed. If you do have it, it is installed.
SQL Server is installed, now where do I get the Northwind Database?
Well, this was a struggle even for me. All the posts say the database creation script was installed with Visual Studio, but I sure don’t have any database creation scripts installed.
So I searched the web and Microsoft’s site for a while.
So as of 3/4/2010, there was not “new” Northwind database, just and old one for SQL 2000. Which is fine because that old database is what most the sample code you find will be using.
I clicked on the Download link next to SQL Server 2000 Sample DBs.
I downloaded a ZIP file.
I extracted it.
I found the instnwnd.sql script among the extracted files.
How do I use the instnwnd.sql file to install the Northwind Database
This instnwnd.sql is nothing more than SQL script that will install the Northwind database for you. Well, you basically need your SQL server to run this script file and that is it.
If you have SQL Server Management Studio, just open it up and connect to your database, then File | Open the script and run it. But maybe you don’t know what SQL Server Management Studio is, let alone how to open it.
Sound easy right.
Well, everything sounds easy to some one who knows exactly how to do it, but if you don’t now how, it doesn’t sound easy. If you are among those that are hearing about this for the first time, let me help you.
Well, every server that has SQL Server installed has a command line tool installed called sqlcmd.exe. Hey, if I give you a command line you can run it, even if you don’t know what is really going on.
So just open a command prompt and run this command:
C:\Users\UserName>
sqlcmd -E -i c:\path\to\instnwnd.sql
Changed database context to ‘master’.
Changed database context to ‘Northwind’.
Ok, the database installed now what?
Well, now you have the Northwind database installed.
From here you are one your own getting whatever sample code you have to connect to this database and compile.
Then install Subversion, however, one difference you need to make to the install instructions for subversion. You need to install with SASL2 support. When you run make install it is an option.
Ok, now that you have everything is installed, you are were I am and ready to try to get this configured.
Configuring Subversion to use SASL to Authenticate to a MySQL database
Create a simple MySQL database. The following is a simple database creation script that creates a database with one table and two rows.
CREATE DATABASE UserDB;
USE UserDB;
CREATE TABLE `users` ('username' varchar(255), 'password' varchar(255) )
INSERT INTO users VALUES ('user1','pw1');
INSERT INTO users VALUES ('user2@MyReal.com','pw2');
INSERT INTO users VALUES ('user3@myemailaddress.com','pw3');
Note: I use these accounts to show what works and what does not work because the idea of “realms” is confusing.
You may be asking why I don’t have three rows, one for each item: User, Password, Realm.
Well, if you really are creating a new database to handle SVN Users then that is how you should do it and here is it is.
CREATE DATABASE UserDB;
USE UserDB;
CREATE TABLE `users` ('username' varchar(255), 'password' varchar(255) , 'realm' varchar(255))
INSERT INTO users VALUES ('user1','pw1','realm');
INSERT INTO users VALUES ('user2@MyReal.com','pw2','realm');
INSERT INTO users VALUES ('user3@myemailaddress.com','pw3','realm');
However, because I am assuming that you want to authenticate to users that are in an already existing database, realm won’t really exist. However, you may have usernames that are in email format, or not in email format an that makes a difference because Subversion splits the username at an @ symbol and the username is only what is before the @ symbol. See the troubleshooting realms section below.
Edit the following file:
/home/svn/repos/MyApp/conf/svnserve.conf
#
ee /home/svn/repos/MyApp/conf/svnserve.conf
The following are the lines that should NOT be commented out.
Create and edit the following file:
/usr/local/lib/sas2/svn.conf
#
ee /usr/local/lib/sas2/svn.conf
The following are the lines that should NOT be commented out.
[general]
pwcheck_method: auxprop
mech_list: plain
auxprop_plugin: sql
sql_hostnames: localhost
sql_engine: mysql
sql_user: root
sql_passwd: pw
sql_database: UserDB
sql_select: SELECT password FROM users WHERE username='%u'
Note: For debugging add log_level: 7 to this file and then watch the /var/log/debug file.
You should now be able to connect with a client such as TortoiseSVN and connect
Troubleshooting Realms
I found some issues with realms that were really confusing.
Change your /usr/local/lib/sas2/svn.conf file to look like this:
[general]
log_level: 7
pwcheck_method: auxprop
mech_list: plain
auxprop_plugin: sql
sql_hostnames: localhost
sql_engine: mysql
sql_user: root
sql_passwd: pw
sql_database: UserDB
sql_select: SELECT password FROM users WHERE username='%u' or username='%u@%r'
I added two changes:
Turned on logging.
Changes the sql statement to look for username='username' or username='username@realm'
I had to do this because if the user was using an email address, such as john@domain.tld, then it actually makes %u only equal John and seems to drop the @domain.tld and replace it with the name of the realm. However, if your username is John@domain.tld and your realm is domain.tld (so realm and domain are the same), then the code above works. If you domain and realm are not the same, I haven't been able to get this to work.
Go ahead and run this command:
#
tail -f -n 30 /var/log/debug
And then try to authenticate using a client, such as TortoiseSVN. Test all three users. You will see the SQL Queries that are run. It should work to authenticate as user1 or User2, but it cannot authenticate user3 because it just doesn't work due to the way it handles realms. If you have users that don't have email address in your realm, then you need them to have username that are not email addresses.
Final Question
If the password is stored as an md5, sha1, sha256 hash in the database, how do I make this work?

I have previous documents about installing each of the steps above installing Bugzilla. This document will over cover bugzilla.
Installing Bugzilla From Ports
You can install easily from Ports. Make sure your ports tree is up to date:
$
su
Password:
ServerName#
ServerName#
ServerName#
portsnap fetch
portsnap extract
portsnap udpate
Then just do this to install Bugzilla 3.4.2 on FreeBSD 7.2.
ServerName#
ServerName#
cd /usr/ports/devel/bugzilla
make BUGZILLADIR=/usr/local/www/apache22/data/bugzilla install
Note: Make sure you choose the correct install directory for the BUGZILLADIR parameter. By default Apache 2.2 is only serving up files in /usr/local/www/apache22/data/ so by install bugzilla there, you will be able to access bugzilla with this url: http://www.YourWebSite.com/bugzilla
You will be asked to select your compile options throughout. If you don’t want to be promtped, and you want to accept the defaults, use this command.
ServerName#
make BATCH=yes install
Now that you have Bugzilla 3.4.2 on your FreeBSD 7.2 server, you are not finished. We now need to connect to connect it to a database, which I am assuming is MySQL but could just as easily be Postgresql.
Resetting the file ownership recursively on the bugzilla folder
Make sure that the bugzilla folder and all subfolders are owned by www:www.
Note: If you have installled everything including MySQL using the defaults, you will see this warning:
WARNING: You need to set the max_allowed_packet parameter in your MySQL configuration to at least 3276750. Currently it is set to 1048576. You can set this parameter in the [mysqld] section of your MySQL configuration file.
You should now be able to connect to your server: http://YourServer/bugzilla

Do I have to create the database in a special way?
Not if you configure the setting globally. However, if you don’t configure unicode support globally then yes you have to create your database in a specific way.
Red Hat does not have the MySQL client installed with the server, you have to download a separate RPM and install it. But it is really easy. Download both RPMs and install them.
The Database folder is /var/lib/mysql.
For the global configuration there is not a my.cnf file created by default.
Same as FreeBSD, there isn’t one used by default and you have to copy one and use it.
You can create your own my.cnf or you can copy one of the examples.
In order to get the my.cnf to work, you should copy it and change the owner and add the [mysqld] settings.

SELECT * FROM User WHERE LastName='O'Conner'
INSERT INTO User (FirstName, LastName, UserName, Email) VALUES ('John','O'Conner','jo'conner','joconner@somedomain.tld')
Well, that is obviously not going to work, because the apostrophe or single quote in the name O’Conner is going to break the query syntax.
You have to have two single quotes to use a quote.
SELECT * FROM User WHERE LastName='O''Conner'
INSERT INTO User (FirstName, LastName, UserName, Email) VALUES ('John','O'Conner','jo''conner','joconner@somedomain.tld')
Ok, so there are two ways to make sure you have two quotes in C#:
You manage the query string yourself.
You use a DataTable and let it manage the query string for you.
Managing the query string yourself
Ok, the answer is simple. You need two single quotes next to each other.
Now, when you have single string, this is easy to do. You need to replace each instance of a single quote with two single quotes using this function which already exists for you:
Here is an example of doing it wrong, then fixing it. Step through this in a debugger.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace SingleQuoteInSQL
{
class Program
{
static void Main(string[] args)
{
string FirstName = "John";
string LastName = "O'Conner";
string UserName = "joconner";
string Email = "joconner@domain.tld";
// Both these queries are broken because of the space.
string strQuery1 = "SELECT * FROM User WHERE LastName='" + LastName + "'";
string strQuery2 = "INSERT INTO User (FirstName, LastName, UserName, Email) VALUES (" +
"'" + FirstName + "'," +
"'" + LastName + "'," +
"'" + UserName + "'," +
"'" + Email + "')";
// This will actually break your query too, because it will replace valid single quotes
// with two single quotes. You need to do this on the actually data strings.
strQuery1 = strQuery1.Replace("'", "''"); //
strQuery2 = strQuery1.Replace("'", "''");
// Replace any intance of a single quote with two single quotes, ''.
// IMPORTANT: Typing two single quotes ('') is not the same as a double quote (").
FirstName = FirstName.Replace("'", "''");
LastName = LastName.Replace("'", "''");
UserName = UserName.Replace("'", "''");
Email = Email.Replace("'", "''");
// Both these queries are working now;
strQuery1 = "SELECT * FROM User WHERE LastName='" + LastName + "'";
strQuery2 = "INSERT INTO User (FirstName, LastName, UserName, Email) VALUES (" +
"'" + FirstName + "'," +
"'" + LastName + "'," +
"'" + UserName + "'," +
"'" + Email + "')";
}
}

Using a DataTable to manage this for you automagically
This actually looks like more work at first, but really when handling a lot of data, it is much more easy to code using DataTables and DataRows.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data;
using System.Data.SqlClient;
namespace SingleQuoteInSQL
{
class Program
{
static void Main(string[] args)
{
string FirstName = "John";
string LastName = "O'Conner";
string UserName = "joconner";
string Email = "joconner@domain.tld";
// Create the connection
string mConnectionString = "Data Source=ServerName; user id=UserName; password=pw; Initial Catalog=DatabaseName;";
SqlConnection mSqlConnection = new SqlConnection(mConnectionString);
// Create a data adapter, this is what does the magic.
String mQueryForSqlDataAdapter = "Select * from TableName";
SqlDataAdapter tmpSqlDataAdapter;
SqlCommandBuilder tmpSqlCommandBuilder;
DataTable tmpDataTable = new DataTable();
tmpSqlDataAdapter = new SqlDataAdapter(mQueryForSqlDataAdapter, mSqlConnection);
// Use the SqlDataAdapter to create a table with the right schema but no data
tmpDataTable = tmpSqlDataAdapter.FillSchema(tmpDataTable, SchemaType.Mapped);
// Create a SqlCommandBuilder
tmpSqlCommandBuilder = new SqlCommandBuilder(tmpSqlDataAdapter);
// Create a DataRow and populate it
DataRow row = tmpDataTable.NewRow();
row["FirstName"] = FirstName;
row["LastName"] = LastName;
row["UserName"] = UserName;
row["Email"] = Email;
// Add this row to the DataTable
tmpDataTable.Rows.Add(row);
// Write this to the database
tmpSqlDataAdapter.Update(tmpDataTable);
}
}
}
Notice we didn’t have to do a string replace of ‘ for ”.
Ok, so I am in the middle of developing a database tool and so I populate a bunch of data, (by adding a bunch of rows), to a column that is AUTOINCREMENT.
So I have 3725 rows for a feature that is working. Now I am developing other features and debuggin them and so I want to reset the database to the same point it was before I started debugging.
So I am deleting all the rows above 3725, however my next AUTOINCREMENT number continues to go up.
I have this handy little SQL statement that should fix that:
To set the table back to 0.
DBCC CHECKIDENT (MyTable, RESEED, 0)
Now, if I set the table back to 0 that can be a problem if you still have rows in it.
The next row you try to insert will give you an error.
Msg 2627, Level 14, State 1, Line 1
Violation of PRIMARY KEY constraint ‘PK_Person’. Cannot insert duplicate key in object ‘dbo.Person’.
The statement has been terminated.
So if you have rows, try this:
DECLARE @size int
SET @size=(SELECT COUNT(*) From MyTable)
DBCC CHECKIDENT (MyTable, RESEED, @size)
There is a Database Publishing Wizard 1.1 you can download that may work for SQL Server 2005, but didn’t work for me with SQL Server 2008. However,Database Publishing Wizard 1.3 is installed with Visual Studio 2008 but I cannot find a separate download. This tool gets you the schema and data and everything but the “drop and create database” script.
So I think you need Visual Studio 2008 for this for SQL Server 2008 to get it. I am not sure why I cannot find it separately. Maybe Microsoft has a reason.
Step 1 – In Visual Studio 2008, go to Tools | Connect to Database and connect to a MS SQL database.
Under the Server Explorer window, the connection now appears.
Step 2 – Expand Data Connections.
Step 3 – Right-click on the connection and choose Publish to provider.
Step 4 – Click Next.
Step 5 – Choose the database.
Step 6 – Click Next.
Step 7 – Select the publishing options (such as to export the schema and data or just the schema).
Step 8 – Choose a file.
Step 9 – Click Finish.
Step 10 – The one thing this is missing is the script to drop and create the database. You can easily get this from Microsoft SQL Server Management Studio 2008 (there is a free Express version if you don’t have it). Just connect to the database, right-click on the database and choose Script Database as | Drop And Create to | Clipboard. Now past this text to the top of your file you just created.
