Oracle SQL - REGEXP_LIKE包含az或AZ以外的字符

Question

我想创建一个查询,我选择所有包含非az或AZ字符的记录

所以这样的事情

SELECT * FROM mytable WHERE REGEXP_LIKE(column_1, '![A-Z] [a-z]')

Answer 1

该^否定字符类:

SELECT * FROM mytable WHERE REGEXP_LIKE(column_1, '[^A-Za-z]')

Answer 2

就像是

select *
  from foo
 where regexp_like( col1, '[^[:alpha:]]' ) ;

应该管用

SQL> create table foo( col1 varchar2(100) );

Table created.

SQL> insert into foo values( 'abc' );

1 row created.

SQL> insert into foo values( 'abc123' );

1 row created.

SQL> insert into foo values( 'def' );

1 row created.

SQL> select *
  2    from foo
  3   where regexp_like( col1, '[^[:alpha:]]' ) ;

COL1
--------------------------------------------------------------------------------
abc123
