Question

我有一个SQL Server表。现在，此表包含主键Id，A, B, C, D, E, F, G

等列

现在我想从这个表中选择行

A=A, B=B, C=C, D=D and G > 132

所以我试图从这个表中选择哪些行A,B,C,D列具有相同的数据和G列数据＆gt; 132。

那我怎么能这样做？谢谢。

我尝试了此查询，但返回了相同的Id行

    SELECT TableA.Id,TableA.UserId,TableA.MaximumHp,TableA.Attack,TableA.Defense,TableA.SpAttack,TableA.SpDefense,TableA.Speed
FROM myTable as TableA
Inner Join myTable as TableB on 
TableA.MaximumHp = TableB.MaximumHp
  AND TableA.Attack = TableB.Attack
  AND TableA.Defense = TableB.Defense
    AND TableA.SpAttack = TableB.SpAttack
      AND TableA.SpDefense = TableB.SpDefense
        AND TableA.Speed = TableB.Speed
       AND TableA.Id != TableB.Id

听起来你想把桌子加到自己身上

SELECT *
FROM Table t1
Inner Join Table t2 on t1.A = t2.A
  AND t1.B = t2.B
  AND t1.C = t2.C
  AND t1.D = t2.D
  AND t1.G > 132
  AND t1.ID <> t2.ID

我认为你的意思是重复的。告诉我这是否是您正在寻找的。

SELECT [Table].A, [Table].B, [Table].C, [Table].D, [Table].E, [Table].F, [Table].G
FROM [Table] LEFT JOIN (SELECT A, B, C, D FROM [Table] 
GROUP BY A, B, C, D
HAVING count(*) > 1)
AS sub ON ([Table].A=sub.A) AND ([Table].B=sub.B) AND ([Table].C=sub.C) AND ([Table].D=sub.D)
WHERE G>132 and sub.A is not null;

这将为您提供a，b，c和D等于表中另一行的所有行...并且G＆gt; 132
