Question

想知道是否有更好的方式来运行此查询，因为BETWEEN重复自我，我只需要添加一个新规则(and local=1) OUTPUT就是我想要的，只是想知道是否有＆＃39;更短或更好的版本。

SELECT COUNT(*) as total, 
(SELECT COUNT(*) FROM orden WHERE actual_date BETWEEN '2017-01-01' AND '2017-01-05' and local=1 and forma_pago='tarjeta' and status=4) as Principal 
FROM orden 
WHERE actual_date BETWEEN '2017-01-01' AND '2017-01-05'
and forma_pago='tarjeta' 
and status=4

Answer 1

这应该这样做：

SELECT COUNT(*) AS total
    , SUM(CASE
            WHEN local = 1 THEN 1
            ELSE 0
         END) AS Principal
FROM   orden
WHERE  actual_date BETWEEN '2017-01-01' AND '2017-01-05'
      AND forma_pago = 'tarjeta'
      AND status = 4;
