SQL Error involving Auto Close

This was a solution I discovered years ago when troubleshooting a customer’s database problem.  The error thrown was:

The log for database ‘database_name’ is not available. Check the event log for related error messages. Resolve any errors and restart the database.

It was caused by the Auto Close database property being set to true.  To rectify the issue, you will need to bring the database offline, bring it back online again, and then set the Auto Close property to false.

Setting Up ASP.NET Membership Tables

My hosting provider is deprecating this information because there are newer methods of setting up logins and handling authentication, however, I believe this information is still invaluable to those who haven’t adopted the newer methods and/or can’t keep up with the pace of all the technological changes in the world (or don’t want to).  And in the interest of preserving knowledge, here it is:

The following steps create the full Application Services database schema on our SQL Server database:

Open the command prompt on your local computer, and navigate to:
C:\WINDOWS\Microsoft.NET\Framework\[framework version]

Execute the command:
aspnet_regsql.exe -S DBServerName -U DBLogin -P DBPassword -A all -d DBName

Currently, there is no management interface to manage the membership database other than using Visual Web Developer or creating your own application using the membership provider class. Here is an example of how to configure Visual Studio or Visual Web Developer to manage the membership database:

1. Create a web application in Visual Web Developer or Visual Studio.
2. Open the web.config file.
3. The default membership provider uses a connection string called “LocalSqlServer”.  Therefore, replace:

<connectionstrings></connectionstrings>

with:

<connectionstrings>
<remove name="LocalSqlServer"></remove>
<add name="LocalSqlServer" connectionString="Data Source=DBServerName;Integrated Security=false;Initial Catalog=DBName;User ID=DBLogin;Password=DBPassword" providerName="System.Data.SqlClient"></add>
</connectionstrings>

4. Save and close the web.config file.
5. Go to Website menu and run the ASP.NET Configuration tool. This will open the Web Site Administration tool.
6. In the Web Site Administration tool, go to the Security tab.
7. Click on “Select authentication type”.
8. Select “From the internet”. Click the Done button.
9. Create your admin roles and users.
10. Then create access rules.
11. Create a rule that applies to the “Anonymous users” with “Deny” permissions.
12. Create another rule that applies to the admin role you created with “Allow” permissions.

Your application is now ready to use the membership provider, and you can begin creating your log in forms.

Easy Way to GRANT/REVOKE Rights to Tables within a Microsoft SQL Server Database

Yesterday, a customer asked for help setting up an additional database user with only SELECT rights to his database.  He had a lot of tables, so the easiest solution I came up with involved using the sp_MSforeachtable system stored procedure.  Here’s the T-SQL code:

EXEC sp_MSforeachtable
'REVOKE ALL ON ? FROM username'

EXEC sp_MSforeachtable
'GRANT SELECT ON ? TO username'

Make sure you replace username with the database username that you want the rights applied to.
