pg_result_error
(PHP 4 >= 4.2.0, PHP 5, PHP 7)
pg_result_error — Get error message associated with result
Description
pg_result_error
( resource $result
) : string
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);?>
