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.

Do this:

Try
    reader = cmd.ExecuteReader()   
Catch sqlEx as SQLException
  MessageBox.Show sqlEx.ToString
End

The message box will give you the exact error as reported by the connection. Post what it says and someone should be able to give you a better idea how to fix it.

Without knowing the info Technome spoke of, I would venture a guess that in your sql string you have a single quote on one side of the table name, and not the other.

Yep. That was it. Nothing wrong with the code aside from that. I'm just not thinking today! Thanks.
