pg_result_error_field

(PHP 5)pg_result_error_field -- Returns an individual field of an error report.

Описание

string pg_result_error_field (resource result, int fieldcode)

pg_result_error_field() returns one of the detailed error message

fields associated with result resource. It is only available

against a PostgreSQL 7.4 or above server. The error field is specified by

the fieldcode.

Because pg_query() and pg_query_params() return FALSE if the query fails,

you must use pg_send_query() and

pg_get_result() to get the result handle.

If you need to get additional error information from failed pg_query() queries,

use pg_set_error_verbosity() and pg_last_error()

and then parse the result.
