pg_result_error

(PHP 4 >= 4.2.0, PHP 5)

pg_result_error -- Get error message associated with result

Popis

string 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.

Seznam parametrů

result: PostgreSQL query result resource, returned by pg_query(), pg_query_params() or pg_execute() (among others).

Návratové hodnoty

Returns a string if there is an error associated with the result parameter, FALSE otherwise.
