Previous Comments: ------------------------------------------------------------------------ [2011-05-19 16:29:01] courts at siam dot org Description: ------------ When using a PostgreSQL rule to return a value on an INSERT, pg_query's return is a resource that contains the correct information, while pg_query_params's return is empty/null. Tested and confirmed on: 'Linux 2.6.18-194.17.1.el5 #1 SMP Mon Sep 20 07:12:06 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux' running PHP 5.3.5-1 [Note: Production server - can't upgrade myself for testing] and on 'Linux 2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:50 UTC 2011 i686 i686 i386 GNU/Linux' virtual machine running PHP 5.3.5-1 and then also tested against 5.3.6 compiled from source. Test script: --------------- Database setup: CREATE DATABASE test WITH OWNER = postgres ENCODING = 'UTF8' LC_COLLATE = 'en_US.UTF-8' LC_CTYPE = 'en_US.UTF-8' CONNECTION LIMIT = -1; CREATE SEQUENCE widget_id_seq INCREMENT 1 MINVALUE 1 MAXVALUE 9223372036854775807 START 1 CACHE 1; ALTER TABLE widget_id_seq OWNER TO postgres; CREATE TABLE widget ( id serial NOT NULL, widgetname character varying(20) NOT NULL, inserttime timestamp without time zone NOT NULL, CONSTRAINT widget_pkey PRIMARY KEY (id) ) WITH ( OIDS=FALSE ); ALTER TABLE widget OWNER TO postgres; CREATE OR REPLACE RULE get_widget_id_on_insert AS ON INSERT TO widget DO SELECT currval('widget_id_seq'::text::regclass) AS id; PHP test script: <?php $db_connection = pg_connect("host=localhost dbname=test user=postgres"); $good_query = "INSERT INTO widget (widgetname, inserttime) VALUES ('Good Test Widget', NOW())"; $good_result_ref = pg_query($db_connection, $good_query); $good_result_data = pg_fetch_array($good_result_ref); echo 'Good result ID:' . $good_result_data['id'] . "\n"; $bad_query = 'INSERT INTO widget (widgetname, inserttime) VALUES ($1, NOW())'; $bad_params = array('Bad Test Widget'); $bad_result_ref = pg_query_params($db_connection, $bad_query, $bad_params); $bad_result_data = pg_fetch_array($bad_result_ref); echo 'Bad result ID:' . $bad_result_data['id'] . "\n"; pg_close($db_connection); exit; ?> Expected result: ---------------- (Note: The difference between this and the actual result is that "Bad result ID:" has an integer value (its id) accessible) [justin@mybox ~]$ php rule_failure.php Good result ID:1 Bad result ID:2 [justin@mybox ~]$ php rule_failure.php Good result ID:3 Bad result ID:4 [justin@mybox ~]$ psql --dbname test --user postgres psql (8.4.7) Type "help" for help. test=# SELECT * FROM widget; id | widgetname | inserttime ----+------------------+---------------------------- 1 | Good Test Widget | 2011-05-18 15:57:22.182711 2 | Bad Test Widget | 2011-05-18 15:57:22.187533 3 | Good Test Widget | 2011-05-18 15:57:26.16656 4 | Bad Test Widget | 2011-05-18 15:57:26.170966 (4 rows) test=# Actual result: -------------- [justin@mybox ~]$ php rule_failure.php Good result ID:1 Bad result ID: [justin@mybox ~]$ php rule_failure.php Good result ID:3 Bad result ID: [justin@mybox ~]$ psql --dbname test --user postgres psql (8.4.7) Type "help" for help. test=# SELECT * FROM widget; id | widgetname | inserttime ----+------------------+---------------------------- 1 | Good Test Widget | 2011-05-18 15:57:22.182711 2 | Bad Test Widget | 2011-05-18 15:57:22.187533 3 | Good Test Widget | 2011-05-18 15:57:26.16656 4 | Bad Test Widget | 2011-05-18 15:57:26.170966 (4 rows) test=# ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=54863&edit=1
