pg_result_error

(PHP 4 >= 4.2.0, PHP 5, PHP 7)

pg_result_error — Get error message associated with result

Description

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.

Parameters

result

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

Return Values

Returns a string. Returns empty string if there is no error. If there is an error associated with the result parameter, returns FALSE.

Examples

Example #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);
?>
