SQLSplit拆分字符串

SQLServer拆分字符串到临时表 无 GOCreate function [dbo].[split](@SourceSql varchar(max),@StrSeprate varchar(10))returns @temp table(line varchar(max))asbegin declare @i int set @SourceSql = rtrim(ltrim(@SourceSql)) set @i = charindex(@StrSep

GO
Create function [dbo].[split]
(
@SourceSql varchar(max),
@StrSeprate varchar(10)
)
returns @temp table(line varchar(max))
as
begin
 declare @i int
 set @SourceSql = rtrim(ltrim(@SourceSql))
 set @i = charindex(@StrSeprate,@SourceSql)
 while @i >= 1
 begin
 if len(left(@SourceSql,@i-1))>0
 begin
 insert @temp values(left(@SourceSql,@i-1))
 end
 set @SourceSql=substring(@SourceSql,@i+len(@StrSeprate),len(@SourceSql)-@i)
 set @i=charindex(@StrSeprate,@SourceSql)
 end
 if @SourceSql <> ''
 insert @temp values(@SourceSql)
 return
end

-----测试
GO
Select * From dbo.split('asd,f,gh,jk,l',',')

--SQL 递归
