Iterate through an MS SQL Server for all it's Databases

Posted on 2007-04-10

Last Modified: 2008-03-06
I am writing an application that need to iterate through an MS SQL Server and list off all the databases contained within a given server.  I have been hunting for some ADO or ADOX object that offers this functionality.  But,  so far,  I have not what I need.  It would seem that such an object would be similar to the ADOX catalog object that allows me to iterate through a connection's tables/views/stored procedures.

Any suggestions would be greatly appreciated.

Thanks,
Howard

Run this on your SQL Server, it will return you a list of all the databases on it:

select * from master.dbo.sysdatabases
0

Well, there is a undocumented stored procedure which can you used for itrating through all the database

EXEC sp_MSforeachdb @command1='PRINT ''Listing ?''', @command2='USE ? SELECT DB_NAME()'

Create an ADO Connection to the SQL Server.
Create an ADO Recordset and execute the T-SQL expression listed by Otana.

In your application it goes something like this.

Public Sub LoopSQLServerDB()
    Dim MyCon As ADO.Connection
    Dim MyRs As ADO.Recordset
    Dim sDBName As String
    Dim sDataSource As String
   
    sDataSource = "TheNameOfYourSQLServer"
   
    Set MyCon = New ADO.Connection
   
    MyCon.ConnectionString = "Provider=SQLOLEDB;Integrated Security=SSPI;" & _
                "trusted_connection=yes;" & _
                "Persist Security Info=True;" & _
                "Initial Catalog=Master" & _
                ";Data Source=" & sDataSource
   
    MyCon.Open
    Set MyRs = MyCon.Execute("Select * from sysdatabases")
   
    Do While Not MyRs.EOF
        sDBName = MyRs.Fields("name")
        MyRs.MoveNext
    Loop
End Sub
