根据列中的逗号拆分列值

Question

我有一个名为Test的表，具有以下值

ID Name Description
1  Xyz   Mumbai,Delhi

我想要Sql查询，它将给出如下输出

ID Name Description
1  Xyz   Mumbai
1  Xyz   Delhi

Answer 1

您可以将regexp_substr与'[^,]+'模式一起用作第二个参数，以分隔逗号分隔的字符串

with tab( ID, Name, Description ) as
(
 select 1,'Xyz','Mumbai,Delhi' from dual
)
select ID, Name, 
       regexp_substr(Description,'[^,]+',1,level)
       as Description
  from tab 
 connect by level <= regexp_count(Description,',')+1;

ID  NAME   DESCRIPTION
--  ----   -----------
1   Xyz    Mumbai
1   Xyz    Delhi
