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
调用：Select * From dbo.split('1003,1004,1005',',')
结果如下：
100310041005
