sql里没有数组类型所以没有Split
create function dbo.fn_split
(
@inputstr varchar(8000),
@seprator varchar(10)
)
returns @temp table (a varchar(200))
as
begin
declare @i int
set @inputstr = rtrim(ltrim(@inputstr))
set @i = charindex(@seprator, @inputstr)
while @i >= 1
begin
insert @temp values(left(@inputstr, @i - 1))
set @inputstr = substring(@inputstr, @i + 1, len(@inputstr) - @i)
set @i = charindex(@seprator, @inputstr)
end
if @inputstr <> '\'
insert @temp values(@inputstr)
return
end
go
--调用
declare @s varchar(1000)
set @s='1,2,3,4,5,6,7,8,55'
select * from dbo.fn_split(@s,',')
drop function dbo.fn_split
