Try wrapping the SELECT with parentheses. Elvis Celebrating 10-Years of SQL Performance Excellence -----Original Message----- Subject: RE: Simple(?) SQL question I may be doing something wrong, or MS-SQL is just a tad different from System i. On our test system, I entered this: update pre_case as a set (a.patient_name) = select coalesce(b.patient_name,a.patient_name) from demographic as b where a.medical_record_no = b.medical_record_no and a.medical_record_no = '990030133' Here is the error I received: Server: Msg 156, Level 15, State 1, Line 1 Incorrect syntax near the keyword 'as'. For testing, I just wanted to modify records associated with a single medical record. Likely, that will have to be what will be done on the live database. Too much unusual data to do a global change. So, anybody either see something wrong with what I entered, or perhaps the statement only works on System i, as written? It is Friday. This mess will still be here next week.
