This is a multipart message in MIME format. -- [ Picked text/plain from multipart/alternative ] One update: update rob/casetest set testfld= case when substr(testfld,1,3)='300' then ('400' || substr(testfld,4,7)) when substr(testfld,1,3)='310' then ('410' || substr(testfld,4,7)) else testfld end Previously I forgot the 'else'. I didn't fail in my earlier test because I had all records covered. But when I added a record that didn't meet the when's it horfed. The else fixed it. This SQL allows you to update a file in one pass. If it is a large file, this may be significant.
