SQL Server常用技巧

1：在SQL语句中，将存储过程结果集（表）存入到临时表中

insert into #tmp EXEC P_GET_AllChildrenComany '80047'

说明：#tmp要提前创建好

2：字符串循环分割处理

1：字符串分割循环
declare @str varchar(1000)
declare @splitchar varchar(5)

set @str='01,02,333,U04,5,'
set @splitchar=','
declare @location int
set @location=charindex(@splitchar,@str)
while @location<>0
begin
print substring(@str,1,@location-1)

set @str=substring(@str,@location+1,len(@str)-@location)

set @location=charindex(@splitchar,@str)

end

3：字段累计拼接（）

DECLARE @Salary VARCHAR(MAX) =''
SELECT @Salary = @Salary + '[' + SalaryItemID +'],' FROM Rlzy_MDB.dbo.U_SalaryItems
SET @Salary=SUBSTRING(@Salary,1,LEN(@Salary)-1)

　　4:获取表结构信息

exec sp_help 'SD_001_FM03_RESULT'
