年底了,职员都有长薪金的机会,人事部需要做一份报表,就是显示薪金前后值的一份报表。为了实现这样的功能,使用SQL的OUTPUT功能,即可实现原薪金与新薪金比较的报表。
SELECT [MemberId],[Name],[Salary] FROM [dbo].[Member]
结果
MemberId Name Salary
1 Mr. John 2200.00
2 Mr. Joe 2500.00
使用OUTPUT功能实现报表:
代码
UPDATE [dbo].[Member]
--每个职员长5%薪金
SET [Salary] = [Salary] * (1 + 0.05)
OUTPUT
deleted.[MemberId] AS [MemberId],
deleted.[Name] AS [Name],
deleted.[Salary] AS [OldSalery],
inserted.[Salary] AS [newSalery]
--每个职员长5%薪金
SET [Salary] = [Salary] * (1 + 0.05)
OUTPUT
deleted.[MemberId] AS [MemberId],
deleted.[Name] AS [Name],
deleted.[Salary] AS [OldSalery],
inserted.[Salary] AS [newSalery]
结果:
MemberId Name OldSalery newSalery
1 Mr. John 2200.00 2310.000000
2 Mr. Joe 2500.00 2625.000000
