pg_result_error
(PHP 4 >= 4.2.0, PHP 5)
pg_result_error — Get error message associated with result
Description
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 if there is an error associated with the result parameter, FALSE otherwise.
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);
?>
