sql server 自定义split(分割)函数

ALTER function [dbo].[split]

)
returns @temp table(F1 varchar(100))
as
begin
declare @i int

end
set @SourceSql=substring(@SourceSql,@i+1,len(@SourceSql)-@i)
set @i=charindex(@StrSeprate,@SourceSql)
end

//应用
--开始迭代分割出来的参数
declare @str nvarchar(10)
declare auth_cur cursor for select F1 from split(要分割的参数,'分隔符')
open auth_cur
fetch next from auth_cur into @str
while ( @@fetch_status = 0 )

//做处理
