      If you are using transactions, you need to call
      <B

      UPDATE, or DELETE query, not after the commit.

      When using UPDATE, FrontBase will not update columns where the
      new value is the same as the old value.  This creates the
      possibility that <B
CLASS="function"
>fbsql_affected_rows()</B
> may not
      actually equal the number of rows matched, only the number of
      rows that were literally affected by the query.
     </P

><P
>&#13;     If the last query failed, this function will return -1.
