#45610 [NEW]: pg_field_type returns wrong type

From: thuejk at gmail dot com Operating system: Linux (probably all) PHP version: 5.2.6 PHP Bug Type: PostgreSQL related Bug description: pg_field_type returns wrong type Description: ------------ For some queries, pg_field_type() returns the wrong field type. It seems to happen when you do a "SELECT *" and there are more than one table in the FROM-clause, with common columns eliminated. I tested with postgresql 7.4 and postgresql 8.1, with the same result. Reproduce code: --------------- <?php $params = "host=localhost dbname=testdb user=testuser password=123456"; pg_pconnect($params); pg_query("begin"); pg_query("CREATE TABLE test1(a integer)"); pg_query("CREATE TABLE test2(a integer, c varchar)"); pg_query("INSERT INTO test1 VALUES (1)"); pg_query("INSERT INTO test2 VALUES (1,'aa')"); $res = pg_query("SELECT * FROM test1 INNER JOIN test2 ON test1.a=test2.a"); $row = pg_fetch_assoc($res); $col_i=0; foreach ($row as $field_name => $dummy) { var_dump($field_name); $type = pg_field_type($res, $col_i++); var_dump($type); if ($field_name == "c") { assert($type != "int4"); } } pg_query("rollback"); ?> Expected result: ---------------- The type of column "c" should be "varchar" Actual result: -------------- The type of column "c" is "int4" -- Edit bug report at http://bugs.php.net/?id=45610&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=45610&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=45610&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=45610&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=45610&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=45610&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=45610&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=45610&r=needscript Try newer version: http://bugs.php.net/fix.php?id=45610&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=45610&r=support Expected behavior: http://bugs.php.net/fix.php?id=45610&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=45610&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=45610&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=45610&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=45610&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=45610&r=dst IIS Stability: http://bugs.php.net/fix.php?id=45610&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=45610&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=45610&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=45610&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=45610&r=mysqlcfg
