[AccessD] Update Query - Need to Speed It Up

Rocky,

  I've see you've already made progress, but you might also want to try
saving the SQL as a querydef, then setting the UseTransaction property to
no.  Depending on the number of records that are being changed, this may or
may not yield an improvement.

  Beyond that, if your still looking for more performance, you can use the
SetOption method of DAO to modify some of the JET engine settings (i.e..
MaxBuffers or PageTimeout).

      Dear List:

      I am running an update query on a table with 2,500,000 records and
it's taking just a bit too long for the my and the client's liking.
      The SQL is:

      UPDATE tblInvoiceDetail SET tblInvoiceDetail.fldInvoiceDetailPPV =
"""", tblInvoiceDetail.fldInvoiceDetailVariancePercent = 0;

      It's setting one field to blank the other to 0.

      Is there a way to make it run any faster?


      MTIA,
