Can't we use [specifier] with like operator with Oracle?

Question

When using the LIKE operator in oracle for matching anyone of the characters can't I use [ specifier ] For eg. Find out the Customer's name starting with either 's' or 'r' SO we can't write query as " select * from emp where customer LIKE '[sr]%'";

Can't we use "[]" braces with LIKE operator in ORACLE?

Answer 1

No, LIKE does not do that.

But you can use regular expressions.

select * from emp where REGEXP_LIKE (customer, '^[sr].*');
