Question

我想让我的报告更快，因为需要花费很长时间来加载，我想知道是否有办法从一个选择中进行多次计数。

例如，使这个选择愿望不会改变计数

SELECT IDS, Fecha_Recarga, Banco_Recarga, Tipo, Status, RefVerif, MontoVerif, RecargaDuplicada FROM transaccionesrr WHERE Fecha_Recarga = '2017-02-07' AND Banco_Recarga = 'BANESCO' AND Tipo = 'RECARGA' AND Status = 'PROCESADA'

根据这个选择的结果我想做多个计数，如

Count (*) WHERE RefVerif = '1' AS RefVerif
Count (*) WHERE RefVerif = '1' AND MontoVerif = '0' AS MontoVerif 
Count (*) WHERE RecargaDuplicada = '1' AS Duplicada

这是我知道的存储过程

SELECT COUNT(*) AS RECARGAS,

(SELECT COUNT(*) FROM transaccionesrr WHERE Tipo = 'RECARGA' AND Status = 'PROCESADA' AND Fecha_Recarga BETWEEN PRM_Fecha_Desde AND  PRM_Fecha_Hasta AND Banco_Recarga = PRM_Banco AND RefVerif = '1') AS VERIFICADAS,

(SELECT COUNT(*) FROM transaccionesrr WHERE Tipo = 'RECARGA' AND Status = 'PROCESADA' AND Fecha_Recarga BETWEEN PRM_Fecha_Desde AND  PRM_Fecha_Hasta AND Banco_Recarga = PRM_Banco  AND RefVerif = '0') AS NOVERIFICADAS,

(SELECT COUNT(*) FROM transaccionesrr WHERE Tipo = 'RECARGA' AND Status = 'PROCESADA' AND Fecha_Recarga BETWEEN PRM_Fecha_Desde AND  PRM_Fecha_Hasta AND Banco_Recarga = PRM_Banco  AND RefVerif = '1' AND MontoVerif = '0') AS MONTOVERIF,

(SELECT COUNT(*) FROM transaccionesrr WHERE Tipo = 'RECARGA' AND Status = 'PROCESADA' AND Fecha_Recarga BETWEEN PRM_Fecha_Desde AND  PRM_Fecha_Hasta AND Banco_Recarga = PRM_Banco  AND RecargaDuplicada = '1') AS DUPLICADAS

FROM transaccionesrr WHERE Tipo = 'RECARGA' AND Status = 'PROCESADA' AND Fecha_Recarga BETWEEN PRM_Fecha_Desde AND  PRM_Fecha_Hasta AND Banco_Recarga = PRM_Banco ;

我试图这样做，因为我认为如果你认为有更好的方式我会受到赞赏会更快。

我一直在努力寻找解决方案，但我找不到任何

使用条件聚合：

SELECT COUNT(*) AS RECARGAS,
       SUM(RefVerif = '1') AS VERIFICADAS,
       SUM(RefVerif = '0') AS NOVERIFICADAS,
       SUM(RefVerif = '1' AND MontoVerif = '0') AS MONTOVERIF,
       SUM(RecargaDuplicada = '1') AS DUPLICADAS
FROM transaccionesrr
WHERE Tipo = 'RECARGA' AND Status = 'PROCESADA' AND
      Fecha_Recarga BETWEEN PRM_Fecha_Desde AND PRM_Fecha_Hasta AND
      Banco_Recarga = PRM_Banco ;
