SQL 实现Split 功能

create function f_split(@SourceSql varchar(max),@StrSeprate char(1))
returns @temp table(a varchar(100))
--实现split功能 的函数
as
begin
--declare @temp as table(a varchar(100))
--declare @SourceSql as nvarchar(max)
--declare @StrSeprate as nvarchar(10)
--set @SourceSql='ABC:BC:C:D:E'
--set @StrSeprate=':'
declare @i int
set @SourceSql=rtrim(ltrim(@SourceSql))
set @i=charindex(@StrSeprate,@SourceSql)
while @i>=1
begin
--print substring(@SourceSql,@i+1,1)
if (substring(@SourceSql,@i+1,1)=@StrSeprate)
begin
set @i=charindex(@StrSeprate,@SourceSql,@i+1)
continue
end
insert @temp values(left(@SourceSql,@i-1))
set @SourceSql=substring(@SourceSql,@i+1,len(@SourceSql)-@i)
set @i=charindex(@StrSeprate,@SourceSql)
end
if @SourceSql<>'\'
insert @temp values(@SourceSql)
return
