Sql Only 字符串搜索

Question

with temp(name) as (select 'abc' from dual
union select '123abc' from dual
union select '1abc3' from dual)
select * from temp where temp.name  like '%[a-z]%'

为什么我无法在输出中获得所有 3 条记录
，我使用的是 Oracle SQL Developer 11g

我使用此查询的原因是:我想检查 Desired 列是否只包含字符串，没有数字和特殊字符

您正在混合 SQL Server 和 Oracle 语法:

SQL SERVER Demo :

with temp(name) as (
      select 'abc' union all select '123abc'  union select '1abc3' 
)
select * from temp where temp.name like '%[a-z]%';
                                        -- [] is T-SQL specific

ORACLE Demo :

with temp(name) as (select 'abc' from dual
union select '123abc' from dual
union select '1abc3' from dual)
select * from temp where regexp_like(temp.name, '[a-z]')
