SQL利用Case When Then多条件判断

When c is not null then c

select substring(convert(varchar(8), getdate(), 112), 1, 8)

+ cast(max_ContractNo as varchar(4))

end max_ContractNo

代码如下复制代码 ALTER PROC NumShowTimes(@numValue NVARCHAR(MAX))ASBEGIN DECLARE @TempTable TABLE(num NVARCHAR(4))---定义存放数字的表 DECLARE @TempNum NVARCHAR(4) -- DECLARE @Value nvarchar(max) SET @Value = @numValue ---判断输入的是否是数字 WHILE(LEN(@numValue)0) BEGIN SET @TempNum=SUBSTRING(@numValue,LEN(@numValue),1) SET @numValue=SUBSTRING(@numValue,1,(LEN(@numValue)-1)) IF @TempNum LIKE'[^0-9]' BEGIN PRINT 'YOU INPUT NOT NUM' RETURN END END ----获取数据插入表中 WHILE(LEN(@Value)0) BEGIN SET @TempNum=SUBSTRING(@Value,LEN(@Value),1) SET @Value=SUBSTRING(@Value,1,(LEN(@Value)-1)) INSERT INTO @TempTable VALUES (@TempNum) END SELECT num,count(num)AS [count] FROM @TempTable GROUP BY numEND

WHERE datediff(Day,Adddate,getdate())=0

+ replicate('0', 4-len(max_ContractNo)) --以指定的次数重复字符表达式

else cast(cast(substring(max(My_ContractNo), 12, 4) as bigint) + 1 as varchar(8))

from (select

[Remarks] [varchar](50) COLLATE Chinese_PRC_CI_AS NOT NULL CONSTRAINT [DF_UserContractNo_Remarks] DEFAULT (''),

SQL利用Case When Then Else End 多条件判断 以指定的次数重复字符

as usestate

when State=1 and Joinstate=0 then 2

else 0

When a is not null then a

When d is not null then d

case

CREATE TABLE [UserContractNo](

From Table Name

[My_ContractNo] [varchar](50) COLLATE Chinese_PRC_CI_AS NOT NULL CONSTRAINT [DF_UserContractNo_My_ContractNo] DEFAULT (''),

from UserContractNo

利用一个存储过程

+'568'

when substring(max(My_ContractNo), 12, 4) is null then '1'

[AddDate] [datetime] NOT NULL CONSTRAINT [DF_UserContractNo_AddDate] DEFAULT (getdate()),

Else ''

Select top 100 State,JoinState, (case

[Id] [int] IDENTITY(1,1) NOT NULL,

去掉判断输入的是否是数字那个while循环,就显示所输入的所字符出现的次数,包括汉字

end )

When b is not null then b

Select

文章介绍了利用sql存储加while一个个判断,然后再利用Case When Then Else End 多条件判断 以指定的次数重复字符。

百家了乐八大技巧 ,when State=1 and JoinState=1 then 1

from UserInfo

End 列名

) s

[ApplyUserDetailID] [int] NOT NULL,
