SQL查询中的"NOT LIKE" [英] 'NOT LIKE' in an SQL query

问题描述

这个简单的查询为什么会返回"ORA-00936:缺少表达式"(您可以说数据库是Oracle):

Why does this simple query return 'ORA-00936: missing expression' (the database is Oracle as you can tell):

SELECT * FROM transactions WHERE id NOT LIKE '1%' AND NOT LIKE '2%'

我觉得很傻，但是我在做什么错了?

I feel silly, but what am I doing wrong?

推荐答案

您错过了第二个NOT LIKE中的字段名称id.试试:

You have missed out the field name id in the second NOT LIKE. Try:

SELECT * FROM transactions WHERE id NOT LIKE '1%' AND id NOT LIKE '2%'

where子句中的AND连接2个全条件表达式，例如id NOT LIKE '1%'，并且不能用于列出id为不喜欢"的多个值.

The AND in the where clause joins 2 full condition expressions such as id NOT LIKE '1%' and can't be used to list multiple values that the id is 'not like'.
