#37124 [Opn->Fbk]: PostgreSQL Query Returns Resource id for Field Value

ID: 37124 Updated by: helly@php.net Reported By: ahaig at penguinmilitia dot net -Status: Open +Status: Feedback Bug Type: PDO related Operating System: Mac OS X 10.4.6 PHP Version: 5.1.2 New Comment: What is the postgres data type you return here? Previous Comments: ------------------------------------------------------------------------ [2006-04-18 18:04:15] ahaig at penguinmilitia dot net I guess I didn't include <?php ?> but I thought I included a full script. You will need to fill in $dsn $user and $password and $table as appropriate. $dsn should refer to a PostgreSQL DB, $table to a table with at least 1 foreign key. Script: <?php $database = new PDO( $dsn, $user, $password ); $statement = $database->prepare("SELECT t.tgargs as args FROM pg_trigger t,pg_class c,pg_proc p WHERE t.tgenabled AND t.tgrelid = c.oid AND t.tgfoid = p.oid AND p.proname = 'RI_FKey_check_ins' AND c.relname =:tablename ORDER BY t.tgrelid"); $table = '<name of table in database with at least 1 foreign key>'; $statement->bindParam( ':tablename', $table ); $statement->execute(); print_r($statement->fetchAll()); die("Here's my error!"); ?> ------------------------------------------------------------------------ [2006-04-18 17:57:30] tony2001@php.net Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If possible, make the script source available online and provide an URL to it here. Try to avoid embedding huge scripts into the report. ------------------------------------------------------------------------ [2006-04-18 17:54:08] ahaig at penguinmilitia dot net Description: ------------ I'm using PostgreSQL 8.0.2 Query: SELECT t.tgargs as args FROM pg_trigger t,pg_class c,pg_proc p WHERE t.tgenabled AND t.tgrelid = c.oid AND t.tgfoid = p.oid AND p.proname = 'RI_FKey_check_ins' AND c.relname =:tablename ORDER BY t.tgrelid :tablename is bound to a var with the value 'tables' (for my particular case), and the same result occurs if I do not use binding and fill the string in myself with 'tables' instead of :tablename. When I run the query in psql it returns: args ------------------------------------------------------------ tables_mainclassname_fkey\000tables\000classes \000UNSPECIFIED\000mainclassname\000object_class\000 tables_databasehandle_fkey\000tables\000databases \000UNSPECIFIED\000databasehandle\000databasehandle\000 (2 rows) Reproduce code: --------------- $statement = $my_PDO_instance->prepare("SELECT t.tgargs as args FROM pg_trigger t,pg_class c,pg_proc p WHERE t.tgenabled AND t.tgrelid = c.oid AND t.tgfoid = p.oid AND p.proname = 'RI_FKey_check_ins' AND c.relname =:tablename ORDER BY t.tgrelid"); $statement->bindParam( ':tablename', $table ); $statement->execute(); print_r($statement->fetchAll()); The same thing occurs if I do: foreach ( $my_PDO_instance->query("SELECT t.tgargs as args FROM pg_trigger t,pg_class c,pg_proc p WHERE t.tgenabled AND t.tgrelid = c.oid AND t.tgfoid = p.oid AND p.proname = 'RI_FKey_check_ins' AND c.relname =:tablename ORDER BY t.tgrelid") as $this_row ) { print_r($this_row); } Expected result: ---------------- Array ( [args] => tables_mainclassname_fkey\000tables \000classes\000UNSPECIFIED\000mainclassname\000object_class \000 ) Array ( [args] => tables_databasehandle_fkey\000tables \000databases\000UNSPECIFIED\000databasehandle \000databasehandle\000 ) Actual result: -------------- Array ( [args] => Resource id #20 ) Array ( [args] => Resource id #21 ) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=37124&edit=1
