Question

我正在研究SQL Developer。我只想要那些有非数字数据的记录。我使用的查询是：

select * from  TBL_NAME where regexp_like (mapping_name,'%[!0-9]%');

奇怪的是，这不起作用。

Answer 1

这个怎么样？如你所说，返回非数字的值。

SQL> with test (col) as
  2    (select 'abc123' from dual union
  3     select '12345'  from dual union
  4     select 'abc'    from dual union
  5     select '($ff3'  from dual union
  6     select '12.345' from dual
  7    )
  8  select col
  9  from test
 10  where not regexp_like (col, '^\d+|(\.\d+)$');

COL
------
($ff3
abc
abc123

SQL>

如果没有小数值，正则表达式甚至更简单：'^\d+$'

一块蛋糕：

SQL> with test (col) as
  2    (select 'ABC'   from dual union
  3     select 'BCE1'  from dual union
  4     select '2GHY'  from dual union
  5     select 'WE56S' from dual union
  6     select 'TUY'   from dual
  7    )
  8  select col
  9  from test
 10  where not regexp_like (col, '\d');

COL
-----
ABC
TUY

SQL>

正则表达式与Oracle匹配
