// Maybe need some changes 

$table = new Zend_Db_Table('ubiw_transactions_wallet'); 

$subSelect = $table->select() 
->from('ubiw_transactions_wallet', array('wallet_transaction_id', 'transaction_type', 'source', 'status')) 
->where($table->getAdapter()->quoteInto('game_id = ?', 1292)) 
->where($table->getAdapter()->quoteInto('player_id = ?', 1538)) 
->order('`date` DESC') 
->limit(100); 

$mainSelect = $table->select() 
->setIntegrityCheck(false) 
->from(array('a' => $subSelect), array('wallet_transaction_ids' => new Zend_Db_Expr('GROUP_CONCAT(wallet_transaction_id)'), 'transaction_type', 'source', 'status')) 
->group(array('a.transaction_type', 'a.status', 'a.transaction_type')); 

$result = $table->fetchAll($select);
