OpenSchema in VB .NET

Does anyone have some sample VB .NET code that shows how to use OpenSchema?


My intent is to ask a database what tables are inside of it.

Then to take that list of tables and ask each table what the column names are that it has.

Hi knowlton,

Are you using this for an Analysis Services cube?  If not I'm not sure if OpenSchema is what you want.

If you just want a list of all tables in the (assuming SQL Server 2000) database, use:

select name, id from sysobjects where xtype = 'U'  

then to get all of the column names, use:

select name from syscolumns where id = <id from previous query>


Cheers,
Hillwaaa

knowlton,

Then I'd suggest looking at the code here: http://www.freevbcode.com/ShowCode.asp?ID=3884

It's VB6 but should be fairly easy to translate to VB .NET, and contains an example on using OpenSchema :)
