想要在Oracle数据库中使用Regular Expression进行数据搜索,可以使用Oracle的REGEXP_LIKE函数来实现。该函数用于在查询中筛选出符合正则表达式的数据。 以下是一个示例查询,使用REGEXP_LIKE函数来搜索名字以字母"A"开头的员工: SELECT*FROMemployeesWHEREREGEXP_LIKE(first_name,'^A'); AI代码助手复制代码 在这个示例中,...

你可以在oracle10g中使用正则表达式肆意地匹配你想匹配的任何字符串了。 所谓正则表达式是对于字符串进行匹配的一种模式。举个例子来说字符串’^198[0-9]$’可以匹配‘1980-1989’,也即80后出生的年份。如果希望统计出公司那些员工是80后的,就可以使用如下的SQL语句: select * from emp where regexp_like(to_cha...

Oracle ORA-12725 unmatched parentheses in regular expression 简单来说就是正则表达式中的括号问题 这种一般就可以锁定使用正则的函数,例如regexp_replace、regexp_like和regexp_substr 可以检查自己的内容里面是不是含有括号这个关键字 例如 regexp_replace(w.subject,(select distinct g.vname from user_gys g,aaa...
1、REGEXP_LIKE 是LIKE语句的正则表达式版本 语法:REGEXP_LIKE(源字符串, 匹配表达式[,匹配选项]) 例子: SELECT product_name FROM oe.product_information WHERE regexp_like (product_name, 'SS[PS]/[VS]'); SS[PS]/[VS]匹配:SSP / V 、SSP / S 、 SSS / V 、 SSS / S ...
