内部连接和查询优化

-2

SELECT client.client_code,client.client_name,dealing_record.transaction_number, 
transaction_type.transaction,payment_status.status,payment_record.Amount_settled, 
payment_record.payment_date 
    FROM client inner Join payment_record on payment_record.client_id= client.client_id 
     inner join dealing_record on 
      dealing_record.dealing_record_id=payment_record.dealing_id 
     inner join payment_status on 
      payment_record.payment_status_id=payment_status.payment_status_id 
     inner Join transaction_type on 
      dealing_record.transaction_type_id=transaction_type.transaction_type_id 
    WHERE status='pending settlement' AND payment_date BETWEEN '07-Nov-2010' AND 
        '17-Nov-2013';

有另一种方式这可以用较小的内部连接来完成？

这真的取决于你的数据库结构。如果查询速度慢，请确保您已获得快速连接所需的正确索引。 – Jon
