SQL 使用 VALUES 生成带数据的临时表实例代码详解

--语法：
--SELECT * FROM (
--VALUES
-- (1,2,3,......)
-- ,(1,2,3,......)
-- ,(1,2,3,......)
-- ,(1,2,3,......)
-- ,(1,2,3,......)
-- ,(1,2,3,......)
--) AS t(c1,c2,c3......)

SELECT * FROM (
　　VALUES (123456),(123456),(123456),(123456),(123456)
) AS T(c1)

-- 试检1
SELECT * FROM (
　　VALUES (123456),(123456),(123456),(123456),(123456)
) AS T(c1)

-- 试检2 生成1个列的临时表
select * into #tmpTable FROM (
 VALUES (123456),(123456),(123456),(123456),(123456)
) AS T(c1)

-- 生成5个列的临时表 #tmpTable2
select * into #tmpTable2 FROM (
 VALUES (1,2,3,4,123456)
  ,(2,3,4,5,123456)
  ,(3,4,5,6,123456)
  ,(4,100,100,3,123456)
  ,(23,4,5,5,123456)
) AS T(c1,c2,c3,c4,c5)

select * from #tmpTable2

-- 计算5列的平均值，求各，最大值，最小值，计数
select * into #tmpTable3 FROM (
 VALUES (1,2,3,4,123456)
  ,(2,3,40000,5000,123456)
  ,(3,4222,5,6000,123456)
  ,(4,100,100,3,123456)
  ,(23,4,5,5,123456)
) AS T(c1,c2,c3,c4,c5)

select a.*
 ,(select Max(NewData) from (values (C1),(C2),(C3),(C4),(C5)) as #temp(NewData)) as nMax 
 ,(select Min(NewData) from (values (C1),(C2),(C3),(C4),(C5)) as #temp(NewData)) as nMai 
 ,(select Sum(NewData) from (values (C1),(C2),(C3),(C4),(C5)) as #temp(NewData)) as nSum 
 ,(select Avg(NewData) from (values (C1),(C2),(C3),(C4),(C5)) as #temp(NewData)) as nAvg 
 ,(select count(NewData) from (values (C1),(C2),(C3),(C4),(C5)) as #temp(NewData)) as nCount 
 from #tmpTable3 as a
