How do I lengthen the timeout interval?

Hi All.

I have a query that takes a couple of minutes to execute in SQL Server. When I try to execute it in the app, I get this error:

SqlException
Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

Source     : .Net SqlClient Data Provider

So how do I lenghten the timeout period to make the error go away?

TIA.

Hi Marci,

All our reports are selectable from a reports menu which is populated from a couple of tables. With each report definition we have a column called MEICmdTimeout into which we can enter a value if the report can be long running. When we create the data table for the report we do the following:

        'Make a copy of the Parameters to the command that won't be cleared
        'when the Parameters in the command are cleared
        Dim Params As SqlParameter() = Sundry.CloneParams(ProcParam)

        'Fill the reporting BO with data
        Dim cmd As New System.Data.SqlClient.SqlCommand
        cmd.CommandType = CommandType.StoredProcedure
        cmd.CommandText = bo.UpdateStoredProcedureName.ToString
        If MEICmdTimeout > 0 Then
            cmd.CommandTimeout = MEICmdTimeout <<<<<< THIS IS WHERE WE SET A SPECIFIC TIME OUT
        End If
        If Not Params Is Nothing AndAlso Params.Length >= 1 Then
            cmd.Parameters.AddRange(Params)
        End If

        bo.FillDataTable(cmd)
        cmd.Dispose()

        Return bo.CurrentDataTable

Cheers, Peter
