Description
   To perform a query against a database, you have to use the
   function 
   query(), that takes the query string
   as an argument. On failure you get a
   
   MDB_Error object.  Be sure to check it with 
   
   MDB::isError(). On success, you get
   MDB_OK or when you set a
   SELECT-statment a result resource handle
  
| Example 33-1. A simple MDB query | <?php
// Once you have a valid MDB object...
$sql = "select * from clients";
$result = $db->query($sql);
// Always check that $result is not an error
if (MDB::isError($result)) {
    die ($result->getMessage());
}
// Continue on with your script
?> |
