# pg_result_error

(PHP 4 >= 4.2.0, PHP 5)

pg_result_error -- Get error message associated with result

## Leírás

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.

## Paraméterek

result

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

## Visszatérési értékek

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

## Példák

Példa 1. pg_result_error() example

`<?php $dbconn = pg_connect("dbname=publisher") or die("Could not connect"); if (!pg_connection_busy($dbconn)) { pg_send_query($dbconn, "select * from doesnotexist;"); } $res1 = pg_get_result($dbconn); echo pg_result_error($res1); ?>`
