Question

我有两个查询，我想获得其中两个的最大值。

myString.Contains(".all")

Answer 1

您甚至可以在一个查询中执行此操作：

SELECT
    CASE WHEN SUM(CASE WHEN HasHuman=0 THEN 1 ELSE 0 END) >
              SUM(CASE WHEN HasHuman=1 THEN 1 ELSE 0 END)
         THEN SUM(CASE WHEN HasHuman=0 THEN 1 ELSE 0 END)
         ELSE SUM(CASE WHEN HasHuman=1 THEN 1 ELSE 0 END) END
FROM [dbo].[Table]
WHERE ItemID IS NOT NULL    -- you were not counting NULLs

Answer 2

SELECT MAX(RC) 
 FROM (SELECT COUNT(p.ItemID) AS RC FROM dbo.[Table]
       WHERE HasHuman=0
       UNION 
       SELECT COUNT(p.ItemID) AS RC FROM dbo.[Table]
       WHERE HasHuman=1
       ) A

Answer 3

您可以在单个查询中计算两个结果，然后应用TOP：

select top 1 
   HasHuman,
   COUNT(p.[ItemID]) as cnt
from [dbo].[Table]
group by HasHuman 
order by cnt desc

SQL MAX值为两个子查询
