note 90912 added to function.pg-field-table

pg_field_table is primarily useful for queries that involve joins between multiple tables, e.g: <?php $res = pg_query("SELECT table1.foo, table2.bar FROM table1 JOIN table2"); echo pg_field_table($res, 0); // Outputs 'table1' echo pg_field_table($res, 1); // Outputs 'table2' ?> However, be aware of a few easy 'gotchas': 1- If your query contains static values in its select-list, pg_field_table() will yield FALSE for those fields (because it was a static value, not one fetched from a table): <?php $res = pg_query("SELECT 'foo', bar FROM table"); echo pg_field_table($res, 0); // FALSE echo pg_field_table($res, 1); // Outputs 'table' ?> 2- If you UNION two queries together from different tables, pg_field_table() will return FALSE for all fields: <?php $res = pg_query("(Select foo, bar from table1) UNION (Select foo, bar from table2)"); echo pg_field_table($res, 0); // FALSE echo pg_field_table($res, 1); // FALSE ?> ---- Server IP: 69.147.83.197 Probable Submitter: 76.2.25.104 ---- Manual Page -- http://www.php.net/manual/en/function.pg-field-table.php Edit -- https://master.php.net/note/edit/90912 Del: integrated -- https://master.php.net/note/delete/90912/integrated Del: useless -- https://master.php.net/note/delete/90912/useless Del: bad code -- https://master.php.net/note/delete/90912/bad+code Del: spam -- https://master.php.net/note/delete/90912/spam Del: non-english -- https://master.php.net/note/delete/90912/non-english Del: in docs -- https://master.php.net/note/delete/90912/in+docs Del: other reasons-- https://master.php.net/note/delete/90912 Reject -- https://master.php.net/note/reject/90912 Search -- https://master.php.net/manage/user-notes.php
