Digg  pg_select
Select records
(PHP 4 >= 4.3.0, PHP 5)
Example 1971. pg_select() example<?php Code Examples / Notes » pg_selectdavid dot tulloh
Valid options are PGSQL_DML_NO_CONV, PGSQL_DML_EXEC, PGSQL_DMP_ASYNC, PGSQL_DML_STRING (pulled out of source code). This function does not support selecting from multiple tables. You can get around this by setting the PGSQL_DML_NO_CONV option. This prevents the error which occurs when the function tries to convert the condition array. I think it is also important to point out that the table_name field is not safe, particularily with the PGSQL_DML_NO_CONV option. The arguements array field is compulsory, as documented. What isn't so clear is that the array has to actually have some values in it, you can't do a select all. In summary, this function is good for a very small subset of basic queries. If you are after anything more complex you are better off with pg_query. wietse
David mentioned that you can't do a Select all. However, when executing this script: <?php $conn_string = "dbname=mydb"; $db = pg_connect($conn_string); $selectfields = array("imgid" => ""); $records = pg_select($db,"mmsfiles",$selectfields); print_r($records); ?> ...I get this result: Array ( [0] => Array ( [imgid] => 1 [file] => /home/wietse/public_html/mms/images/1.gif [thumb] => ) [1] => Array ( [imgid] => 2 [file] => /home/wietse/public_html/mms/images/2.gif [thumb] => ) [2] => Array ( [imgid] => 3 [file] => /home/wietse/public_html/mms/images/3.gif [thumb] => ) [3] => Array ( [imgid] => 4 [file] => /home/wietse/public_html/mms/images/4.gif [thumb] => ) ) |
