select * from users where firstname like '%3%'
where's the catch?
Thank you very much! The catch is that while I'm a novice..and not even the thought that it's so simple - Conor_Ko commented on July 9th 19 at 10:49
It is better not to use *. The returned field is better to specify clearly.
select `id` from `users` where `firstname` like '%3%', for example - meta.Lehne commented on July 9th 19 at 10:52
