SQL查询提取前几个字符

Question

So I have a column in my 'abc' table called 'phones' I need to select everything from the table but only for the people with '520' area codes and the the format for the phone numbers are like so : (540)333-4534 and (804)232-2222.

I am completely new to SQL and this is over my head so any help would be awesome.

I have so far:

SELECT * 
FROM abc
WHERE phones?????????

Answer 1

Use a like statement with a wildcard:

SELECT * 
FROM abc
WHERE trim(phones) like '(520)%'
