SQL LIKE通配符帮助

Question

我需要您的帮助，我有一个简单的查询但不确定如何相应地更改LIKE通配符。这用于查询Oracle数据库。

请你帮忙解决下面的问题，

select * from table_name
where field1 like '1%'
    or field2 like '2%'
    or field3 like '3%'
    or field4 start with 4 but not 4123

Answer 1

select * 
from table_name 
where field1 like '1%' 
or field2 like '2%' 
or field3 like '3%' 
or (field4 like '4%' and field4 not like '4123%')

Answer 2

这是另一种方法：

select *
from table_name
where
  substr (field1, 1, 1) in ('1', '2', '3', '4') and
  field1 not like '4123%'
