(PHP 3 CVS only)

sesam_affected_rows -- Get number of rows affected by an immediate query

Popis

int sesam_affected_rows ( string result_id )

Gets the number of rows affected by an immediate query.

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.

Seznam parametrů

result_id

A valid result id returned by sesam_query().

Návratové hodnoty

Returns the number of rows affected by a query associated with result_id.
