(PHP 4 >= 4.2.0, PHP 5, PHP 7)
Get error message associated with result
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).
Returns:
Returns a string. Returns empty string if there is no error. If there is an error associated with the result
parameter, returns FALSE
.
Examples:
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); ?>
