* An empty base class intended to emulate PEAR connection
* functionality in applications that supply their own database
* abstraction mechanisms. See {@link Auth_OpenID_SQLStore} for more
* information. You should subclass this class if you need to create
* an SQL store that needs to access its database using an
* application's database abstraction layer instead of a PEAR database
* connection. Any subclass of Auth_OpenID_DatabaseConnection MUST
* adhere to the interface specified here.
* Sets auto-commit mode on this database connection.
* @param bool $mode True if auto-commit is to be used; false if
* Run an SQL query with the specified parameters, if any.
* @param string $sql An SQL string with placeholders. The
* placeholders are assumed to be specific to the database engine
* @param array $params An array of parameters to insert into the
* SQL string using this connection's escaping mechanism.
* @return mixed $result The result of calling this connection's
* internal query function. The type of result depends on the
* underlying database engine. This method is usually used when
* the result of a query is not important, like a DDL query.

* @param string $sql An SQL string with placeholders. The
