Well, it of course succeeded! :)

SQL is set-oriented, and updating no matching rows is a valid result.
Now, if you mis-type the update command so there is a syntax or naming
error, you will probably find an error return. Also, if you do a select
on a cursor, then loop through, you might find a return code of "100"
when there are no more rows to select. But updates on well-formed
queries are likely to succeed and return zero.
