请教一个MSSQLSELECT语名的写法
表结构
id ids
1 3,8,83,92,215,7
传入一个值8,92要取出3,83,215,7
即是取出不存在于传入ID串其它所有ID都取出来.
请问这个SELECT 语语应该怎么写。谢谢啦 MSSQL
[解决办法]
drop table t
go
create table t(id int, ids varchar(100))
insert into t
select 1 , '3,8,83,92,215,7'
go
declare @a varchar(100) = '8,7'
;with tt
as
(
select id, ids,@a+',' as a,ids+',' as ids_t
from t
where ids like ('%' + REPLACE(@a,',', '%') + '%')
),
ttt
as
(
select id,ids,
cast(a as varchar(max)) as a,
cast(ids_t as varchar(max)) as ids_t ,
1 as level
from tt
union all
select id,ids,
cast(stuff(a,1,charindex(',',a),'') as varchar(max)) ,
cast(replace(ids_t,left(a,charindex(',',a)),'') as varchar(max)),
level + 1
from ttt
where charindex(',',a) > 0
)
select id, ids_t
from
(
select id, ids,left(ids_t,len(ids_t)-1) as ids_t,
ROW_NUMBER() over(partition by id order by level desc) as rownum
from ttt
)a
where rownum = 1
/*
idids_t
13,83,92,215
*/

--> 测试数据：[tb]
if object_id('[tb]') is not null drop table [tb]
go
create table [tb]([id] int,[ids] varchar(15))
insert [tb]
select 1,'3,8,83,92,215,7'
--------------开始查询--------------------------
Select
a.id,ids=substring(a.ids,b.number,charindex(',',a.ids+',',b.number)-b.number)
into #tb
from
Tb a join master..spt_values b
ON B.type='p' AND B.number BETWEEN 1 AND LEN(A.ids)
where
substring(','+a.ids,b.number,1)=','
declare @str varchar(8000)
set @str = '8,105,7'
set @str = 'select ids='''+replace(@str,',',''''+' union all select ''')+''''
set @str='select ids into #temp from ('+@str+') a select * from #temp a where not exists(select 1 from #tb where ids=a.ids) drop table #tb,#temp'
