If PB does a delete or update for a datawindow row it creates a database DELETE or UPDATE statement with a WHERE clause depending on your update settings in the datawindow object. The "Row Changed between retrieve and update" comes if this statement does not effect a row in the database - the WHERE does not find the row anymore.

It is not easy to say what's going wrong in your case. There are a lot of different reasons. You may check what statement PB will send to the DB in sqlpreview event or you enable tracing of sql.

Hi Ivan;

  This is more likely because of the DWOs "Update Property" setting because the Where clause generated is referencing "all columns" vs "only changed columns". I would check your DWO update settings first.

  If that does not address this issue, I would run an SQL Trace via the SQLCA.DBMS = "TRACE XXX" setting. HTH

When asking a question about database issues, it would be a big help if you told us what database server you are using and which connection method you are using. Any options set in DBParm could be helpful as well.

Please tell us:

The type/version of database server

Connection Method & DBParm used in PB 12.5
