資料庫行轉列 列轉行的Sql語句總結

結果資料庫

通過for xml path把skill按-拼接在一起（-纏繞-寄生-蛛網束縛），然後使用stuff函式把第乙個-符號去掉。

sql code

select a.* 

into #result
from
( select '唐三' as name,'纏繞' as skill
union all
select '唐三' as name,'寄生' as skill
union all
select '唐三' as name,'蛛網束縛' as skill
union all
select '小舞' as name,'爆殺八段摔' as skill
union all
select '小舞' as name,'無敵金身' as skill
) aselect name,
stuff(
(select '-'+ a1.skill from #result a1 where a1.name=a.name for xml path(''))
,1,1,''
) as skill
from #result a
group by name
order by name
drop table #result

結果資料庫

通過convert(xml,'' + replace(a.skill, '-', '

') + '

sql code

select a.* 

into #result
from
( select '唐三' as name,'纏繞-寄生-蛛網束縛' as skill
union all
select '小舞' as name,'爆殺八段摔-無敵金身' as skill
) aselect a.name,b.skill from
(select a.name,skill=convert(xml,'' + replace(a.skill, '-', '
') + '
')from #result a
)aselect skill = n.v.value('.', 'varchar(100)') from a.skill.nodes('/root/v') n(v)
)bdrop table #result

結果資料庫

select '唐三' as name,'纏繞-寄生-蛛網束縛' as skill from dual

union all

select '小舞' as name,'爆殺八段摔-無敵金身' as skill from dual

) aconnect by level <= length(a.skill) - length(regexp_replace(a.skill, '-', '')) + 1) order by name;

select routine_name, routine_definition

from information_schema.routines
where routine_definition like '%表名%'
and routine_type='procedure'
