Is there a parameter I can include in an OLEDB connection string to the following set commands OFF, so I can avoid setting them off in the stored proc(s) that need them off?

ANSI_WARNINGS
ANSI_NULLS
CONCAT_NULL_YIELDS_NULL

I've already tried

AnsiNPW=no        -- works in ODBC
Ansi warnings=off -- puts into Extended properties attribute and adds  
                     several other parameters as well, but no effect

Well, I say no effect - in SQL Profile, the Audit Login for connections show that warnings are on, and there is no batch after (like from a VFP SPT connection) that then sets them off, nor does it show if this is an existing connection.

TIA
