result_id is a valid
result id returned by sesam_query().
Returns the number of rows affected by a query
associated with
result_id.
The sesam_affected_rows()
function can only return useful values when used in
combination with "immediate" SQL statements (updating
operations like INSERT, UPDATE and DELETE)
because SESAM does not deliver any "affected rows"
information for "select type" queries. The number returned is
the number of affected rows.
