pg_result_error (PHP 4 >= 4.2.0, PHP 5) pg_result_error --
Get error message associated with result
Описаниеstring pg_result_error ( resource result )
pg_result_error() returns any error message
associated with the result resource. Therefore,
the user has a better chance of getting the correct error message than
with pg_last_error().
The function pg_result_error_field() can give much greater
detail on result errors than pg_result_error().
Because pg_query() returns FALSE if the query fails,
you must use pg_send_query() and
pg_get_result() to get the result handle.
Список параметров
- result
PostgreSQL query result resource, returned by pg_query(),
pg_query_params() or pg_execute()
(among others).
- offset
Row to move the internal offset to in the result resource.
Rows are numbered starting from zero.
Возвращаемые значения
Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки.
