> For inserts, updates and deletes the values returned are those as set by

the values are those saved after the <TT

This gives access to the *estimated* number of affected rows. The use of
this function saves the overhead of executing a <TT
CLASS="literal"
>SELECT
dbinfo('sqlca.sqlerrdx')</TT
> query, as it retrieves the values that
were saved by the ifx driver at the appropriate moment.
