Error using SQLDataReader

[jgags]

I'm getting the following error at the ' reader = cmd.ExecuteReader() ' line of the code below:

An unhandled exception of type 'System.Data.SqlClient.SqlException' occurred in system.data.dll

Additional information: System error.


Here's the code:

Dim oSQLConn As SqlConnection
        Dim sql As String
        Dim cmd As SqlCommand
        Dim reader As SqlDataReader
 
        sql = "select column_name from information_schema.columns where table_name='selfserve_receipt_item_maillist"
 
        oSQLConn = New SqlConnection("Data Source=RMSDEVSQL1;Initial Catalog= SelfserveDB;user id=kiwisql;Password=fruitcake")
        cmd = New SqlCommand(sql, oSQLConn)
        oSQLConn.Open()
        reader = cmd.ExecuteReader()

I'm somewhat new to ADO.NET (what the heck happen to recordsets!) so I'm not used to working with SQLDataReader. Any help would be appreciated.
