sqlserver分割字串並轉行

插入測試資料

create

table test(name nvarchar(
100)
,class nvarchar(
100)
,[description] nvarchar(
100)
)insert
into test
select
'張三;李四'
,'一二班'
,'小學'
union
allselect
'王五'
,'一三班'
,'小學'
union
allselect
null
,'一四班'
,'中學'
union
allselect
'王二麻子;阿貓;阿狗'
,'一五班'
,'中學'
select
*from test

想要的結果是

引用網上的乙個function(

alter

function
[dbo]
.[splitl]
(@string
varchar
(max)
,@delimiter
varchar
(max)
)returns
@temptable
table
(items varchar
(max))as
begin
declare
@idx
int=
1declare
@slice
varchar
(max)
iflen
(@string
)<1or
len(isnull(
@string,''
))=0
return
while
@idx!=0
begin
set@idx
= charindex(
@delimiter
,@string)if
@idx!=0
set@slice
=left
(@string
,@idx-1
)else
set@slice
=@string
iflen
(@slice
)>
0insert
into
@temptable
(items)
values
(@slice
)set
@string
=right
(@string
,len
(@string)-
@idx)if
len(
@string)=
0break
endreturn
end

select

*from splitl(
(select
top1 name from test)
,';'
)

最終**

with tmp 

as(select row_number(
)over
(order
by name) num,
*,isnull(name,
'a;'
) name1
from test a)
select
case b.items when
'a'then
null
else b.items end name,a.class, a.description
from tmp a
cross
(select
*from splitl(
(select name1 from tmp where num=a.num)
,';'))
as b

如果沒有null，可以這樣寫
