Hi
This error is being generated by a lack of override in sqlsrv.php driver.
Please add the following in wp-db-abstraction\drivers\sqlsrv.php, after print_error method:
/**
* Kill cached query results.
*
* @since 0.71
* @return void
*/
function flush() {
$this->last_result = array();
$this->col_info = null;
$this->last_query = null;
if ( is_resource( $this->result ) )
sqlsrv_free_stmt( $this->result );
}
I’ve found out about this function sqlsrv_free_stmt in http://msdn.microsoft.com/en-us/library/cc296152(v=sql.105).aspx.
Hope this helps people trying to move this plugin forward.
Cheers
