Subject Basic SQL question Update statement
Date Fri, 25 Sep 2009 20:08:31 GMT
I have a trigger something like

..... UPDATE X SET A=(SELECT ..... )

Now, if the embedded SELECT statement returns no rows I would NOT like
to change the value from A to "bank/null" but let it keep the value it
currently has.

Any suggestions for a one liner which fits into a create trigger statement
