pg_delete — 刪除記錄
$connection,$table_name,$assoc_array,$options = PGSQL_DML_EXEC
pg_delete() 刪除符合條件的記錄,條件在 assoc_array 中以 field=>value 格式給出。如果指定了 option,則 pg_convert() 按照該選項(xiàng)作用于 assoc_array 之上。
connectionPostgreSQL database connection resource.
table_nameName 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.
成功時(shí)返回 true, 或者在失敗時(shí)返回 false。 Returns string if PGSQL_DML_STRING is passed
via options.
示例 #1 pg_delete() 例子
<?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";
}
?>
