Got it. But, question, still. Is it true that if you have an SQL backend that it is better to use the SQL Adapters instead of the OLE adapters? -----Original Message----- From: dba-vb-bounces at databaseadvisors.com [mailto:dba-vb-bounces at databaseadvisors.com] On Behalf Of Eric Barro Sent: Monday, November 15, 2004 2:40 PM To: dba-vb at databaseadvisors.com Subject: RE: [dba-VB] OleDBAdapter vs SQLDataAdapter me.startdate.text -----Original Message----- From: dba-vb-bounces at databaseadvisors.com [mailto:dba-vb-bounces at databaseadvisors.com]On Behalf Of Nicholson, Karen Sent: Monday, November 15, 2004 11:24 AM To: dba-vb at databaseadvisors.com Subject: RE: [dba-VB] OleDBAdapter vs SQLDataAdapter So if my @startdate is an unbound field on a form, then @startdate = me.startdate.value? -----Original Message----- From: dba-vb-bounces at databaseadvisors.com [mailto:dba-vb-bounces at databaseadvisors.com] On Behalf Of chizotz at mchsi.com Sent: Monday, November 15, 2004 2:20 PM To: dba-vb at databaseadvisors.com Subject: Re: [dba-VB] OleDBAdapter vs SQLDataAdapter You can parameters to the data adapter select command. Here's a C# example, which you should be able to adapt to VB pretty easily: dsADARpt1.Clear(); daADARpt.SelectCommand.Parameters["@startDate"].Value = startDate; daADARpt.SelectCommand.Parameters["@endDate"].Value = endDate; daADARpt.Fill(dsADARpt1); The SQL in the data adapter uses the parameters basically exactly as you are used to, for example the SQL in the above referenced data adapter includes a line: WHERE (dw_draw1.draw_date >= @startDate) AND (dw_draw1.draw_date <= @endDate) I hope that helps.
