我的表中有 4 列。现在，由于这更像是一项数据清理任务，所以我对性能并不是那么特别。但我仍然想知道可能的选择。

看下面的查询：

SELECT * FROM dsopi_person_addr_rule ADDR WHERE 
addr.src_address_line1 LIKE '%DEP%' 
OR addr.src_address_line2 LIKE '%DEP%'
OR addr.src_address_line3 LIKE '%DEP%'
OR addr.src_address_line4 LIKE '%DEP%';

与 DEP 类似，我还有 10 场比赛。我需要为所有 4 个地址行重复每个匹配项。有更好的方法吗？我个人讨厌一次又一次地写作。

**更新：以下是答案

SELECT *
FROM dsopi_person_addr_rule ADDR
WHERE regexp_like (UPPER(addr.src_address_line1),      'DEP|DPT$|ABT|DIP.|DIPART|AFDEL|AVDEL|AVD.|DIV|PGRD|PGP|PPG')

你可以试试regexp_like函数

您可以尝试编写一个存储过程，将“DEP”部分作为参数输入。然后只需连接所有存储过程调用的结果。
