Re: What's the best way to open a recordset for insert only?

Constant scan cost: 100%
SELECT cost: 0%

Yaaaay SQL Server.

OK, this helps a lot, although I suppose we'll have to trust SQL
Server not to evaluate 0=1 or 1=2 for every existing row in the table.

So it was a failed experiment, and it looks like I'll have to use
the recordset. But I'm wondering if there's a way to open the
recordset so that I can call AddNew on it, but doesn't query the
entire table first.

Use a disconnected recordset opened using a sql query that includes
"WHERE 1=2"

rs.CursorLocation = adUseClient
m_rsname = "select <fields> from " & m_rsname & " WHERE 1=2"
rs.Open m_rsname, m_conn, , adLockBatchOptimistic, adCmdText
Set rs.ActiveConnection = Nothing
'add your records, then
Set rs.ActiveConnection = m_conn
rs.UpdateBatch
