通过行我假设您是说表person
中的行.您正在寻找的是:
By lines I assume you mean rows in the table person
. What you're looking for is:
select p.name
from person p
where p.name LIKE '%A%'; --contains the character 'A'
以上是区分大小写的.对于不区分大小写的搜索,您可以执行以下操作:
The above is case sensitive. For a case insensitive search, you can do:
select p.name
from person p
where UPPER(p.name) LIKE '%A%'; --contains the character 'A' or 'a'
对于特殊字符,您可以执行以下操作:
For the special character, you can do:
select p.name
from person p
where p.name LIKE '%'||chr(8211)||'%'; --contains the character chr(8211)
LIKE
运算符匹配一个模式. Oracle文档中详细描述了此命令的语法.您通常会使用%
符号,因为这意味着匹配零个或多个字符.
The LIKE
operator matches a pattern. The syntax of this command is described in detail in the Oracle documentation. You will mostly use the %
sign as it means match zero or more characters.
