PG_RESULT_ERROR(3)														PG_RESULT_ERROR(3)

pg_result_error - Get error message associated with result

SYNOPSIS
       string pg_result_error (resource  $result)

DESCRIPTION
       pg_result_error(3)  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(3).

	The function pg_result_error_field(3) can give much greater detail on result errors than pg_result_error(3).

	Because pg_query(3) returns FALSE if the query fails, you must use pg_send_query(3) and pg_get_result(3) to get the result handle.

PARAMETERS
	      o $result
		- PostgreSQL query result resource, returned by pg_query(3), pg_query_params(3) or pg_execute(3) (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(3) 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);
	      ?>
