来自第二个查询的未经考虑的空结果

标签： mysql

我有两个问题，我一个接一个地运行。

第一个查询给出了至少有一个列出的类型（LiTy计数> 0）的办事处的ID和名称：

SELECT Off, OffId, COUNT(*) AS NumLiTy
FROM LiTyT
INNER JOIN TaOff USING(OffId)
WHERE Upd Is Null
OR (Upd < DATE_ADD(NOW(), INTERVAL -10  HOUR))
AND (
    Def IS NULL
    OR Def NOT IN (2, 3))
GROUP BY OffId HAVING NumLiTy > 0

第二个查询为我提供了每个列出类型的数据。

SELECT Id, RG, Rif_Year, Rif_Sec,
    IF(Dep_Date='0000-00-00' OR Dep_Date IS NULL,'',Dep_Date) AS Dep_Date,
    Rif_Type, Rif_Obj, Rif_DCU, Rif_DC, 
(
    SELECT Count(*)
    FROM `dt1`
    WHERE `IdLiTy` = LiTyT.Id) AS P_RT,
(
    SELECT Count(*)
    FROM `dt2`
    WHERE `IdLiTy` = LiTyT.Id) AS At_Dep,
(
    SELECT Count(*)
    FROM `dt3`
    WHERE `IdLiTy` = LiTyT.Id) AS Disc,
(
    SELECT Count(*)
    FROM `dt4`
    WHERE `IdLiTy` = LiTyT.Id) AS Provv_C,
(
    SELECT Count(*)
    FROM `dt5`
    WHERE `IdLiTy` = LiTyT.Id) AS Provv_M
FROM LiTyT
WHERE OffId = '1'
AND
(
    LiTyT.Upd IS Null
    OR
    (LiTyT.Upd < DATE_ADD(NOW(), INTERVAL -10  HOUR)))
AND
(
    LiTyT.Def IS NULL
    OR LiTyT.Def NOT IN (2, 3))

问题在于：

第一次查询给了我三个办公室，包括＆gt; 0 

Off      OffId   NumLiTy
Office_1    1      8
Office_2    2      2
Office_3    3      1

但是，当我尝试从第一个办公室获取数据（谁有数= 8）时，我没有得到任何行。

很明显，这两个查询显然只是使用相同的标准，但我无法找到差异并修复它们。

修改： 这是一个检查查询的模式，但我在sqlfiddle上尝试了它，一切似乎都有效。

最后我发现了这个错误！

这是因为在WHERE子句中使用了不正确的括号。所以这就是我现在所拥有的（我故意格式化）：

SELECT OffId, COUNT(*) AS NumLiTy
FROM LiTyT
WHERE Upd Is Null
    OR (
           (
           Upd < DATE_ADD(NOW(), INTERVAL -10  HOUR)
           )
       AND (
           Def IS NULL
           OR (
              Def NOT IN (2, 3)
              )
           )
        )
GROUP BY OffId HAVING NumLiTy > 0

和

SELECT Id, RG, Rif_Year, Rif_Sec,
    IF(Dep_Date='0000-00-00' OR Dep_Date IS NULL,'',Dep_Date) AS Dep_Date,
    Rif_Type, Rif_Obj, Rif_DCU, Rif_DC,
   (SELECT Count(*)
    FROM `dt1`
    WHERE `IdLiTy` = LiTyT.Id) AS P_RT,
   (SELECT Count(*)
    FROM `dt2`
    WHERE `IdLiTy` = LiTyT.Id) AS At_Dep,
   (SELECT Count(*)
    FROM `dt3`
    WHERE `IdLiTy` = LiTyT.Id) AS Disc,
   (SELECT Count(*)
    FROM `dt4`
    WHERE `IdLiTy` = LiTyT.Id) AS Provv_C,
   (SELECT Count(*)
    FROM `dt5`
    WHERE `IdLiTy` = LiTyT.Id) AS Provv_M
FROM LiTyT
WHERE OffId = '1'
    AND (
        Upd Is Null
        OR (
               (
               Upd < DATE_ADD(NOW(), INTERVAL -10  HOUR)
               )
           AND (
               Def IS NULL
               OR (
                  Def NOT IN (2, 3)
                  )
               )
           )
         )
