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
?> |
