I have several tables where I store a check sum value to a field based on values of other fields in the same table. I am trying to use the Update trigger on these tables to replace this CheckSum field with an integer value. Whenver I do, I get a Can not update the cursor error when I issue a replace ChkSum with lnChkSum command in the SP trigger code. I can kind of understand this in that this is a record level data verification trigger. Is there any way I can use a trigger to replace a field value in the record being updated and validated by the update trigger?

TIA!
