查找姓氏中包含特定字符的用户名

Question

在Oracle SQL中,我希望找到所有用户名,其姓氏包含一些特定字符,如('Z','X','D','F')或包含来自'A-F'的某些字符范围.

我试过这个:

 SELECT user_last_name
    FROM   userbase
    WHERE  user_last_name LIKE '%A%' OR user_last_name LIKE '%F%' .

那么我该怎么做呢.

我写了有问题的facebook,虽然它与它没有直接关系,因为它是我先生给出的例子.

更新:我尝试了上面的代码,它适用于很多OR,但我们如何定义一些范围来搜索像IN('Z','X','D','F')或IN('A- F')

如果您使用的是最新版本的Oracle,则应该能够使用正则表达式

SQL> ed
Wrote file afiedt.buf

  1   select first_name, last_name
  2     from employees
  3*   where regexp_like( last_name, 'Z|X|D|[A-F]' )
SQL> /

FIRST_NAME           LAST_NAME

如果您希望搜索不区分大小写

SQL> ed
Wrote file afiedt.buf

  1   select first_name, last_name
  2     from employees
  3*   where regexp_like( last_name, 'Z|X|D|[A-F]', 'i' )
SQL> /
