PHP : Function Reference : PostgreSQL Functions : pg_delete

pg_delete

Deletes records (PHP 4 >= 4.3.0, PHP 5)
mixed pg_delete ( resource connection, string table_name, array assoc_array [, int options] )

pg_delete() deletes records from a table specified by the keys and values in assoc_array. If options is specified, pg_convert() is applied to assoc_array with the specified options.

Parameters

connection

PostgreSQL database connection resource.

table_name

Name of the table from which to delete rows.

assoc_array

An array whose keys are field names in the table table_name, and whose values are the values of those fields that are to be deleted.

options

Any number of PGSQL_CONV_FORCE_NULL, PGSQL_DML_NO_CONV, PGSQL_DML_EXEC or PGSQL_DML_STRING combined. If PGSQL_DML_STRING is part of the options then query string is returned.

Return Values

Returns TRUE on success or FALSE on failure. Returns string if PGSQL_DML_STRING is passed via options.

Examples

Example 1914. pg_delete() example

<?php
 $db
= pg_connect('dbname=foo');
 
// This is safe, since $_POST is converted automatically
 
$res = pg_delete($db, 'post_log', $_POST);
 if (
$res) {
     echo
"POST data is deleted: $res\n";
 } else {
     echo
"User must have sent wrong inputs\n";
 }
?>

One should take care when checking the return value.
0 == false which is not equal with failed delete.
