Hi ,
kindly ignore this as i found what i wanted from the BOL. I have just
found out that the query itself is quite fast after tracing thru the codes.
This query insert data into a temp table. The problem happens when the report
from MS Access is formatting the data not only from the temp table but also
SQL table.
How is it possible to create a ADO connection that can be used by ms access
report instead on relying on the odbc-linked table ?
