Your query doesn't seem to work. I tried it in SQL Server with no luck. What version did you write it with?

This query is for Oracle and possibly other databases that support 'row value constructors'. To make this work on SQL Server, try the following:

SET Col1 = a.Col1, Col2 = a.Col2, Col3 = a.Col3, Col4 = a.Col4 FROM
(SELECT Col1a, Col2a, Col3a, Col4a FROM Table2 WHERE Col5a=Table1.Col5) AS a
WHERE Table1.Col5 IN (SELECT Col5a FROM Table2 )
