mysql - 获得结果的更好方法

Question

想知道是否有更好的方法来运行这个查询，因为 BETWEEN 会自己重复它，我只需要添加一个新规则 (and local=1) OUTPUT 就是我想要的，只是想知道如果有更短或更好的版本。

架构和结果:http://sqlfiddle.com/#!9/e147c/2

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

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;
