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);
?>
