of the problem is that the fields are indexed. Using the indexes to select
only the fields that need updating is appropriate of course if it's not all the
records that need updating. The other option is to delete the index,
update, then rebuild the index. Apparently after each update (each record)
Access foes in and adjusts the index. Removing the index entirely, doing
the updates, then rebuilding the index from scratch is SUPPOSED to be
faster. never actually tried it tho.</FONT></SPAN></DIV>

<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>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

<DIV><FONT face=Arial size=2>The SQL is:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>UPDATE tblInvoiceDetail SET

tblInvoiceDetail.fldInvoiceDetailVariancePercent = 0;</FONT></DIV>

<DIV><FONT face=Arial size=2>It's setting one field to blank the other to
0.</FONT></DIV>
