Question

I have an SQL statement:

SELECT * FROM customers WHERE BINARY login='xxx' AND password='yyyy'

There are no blob/binary fields in the table, do I need the BINARY after the WHERE what else does it do?

Answer 1

BINARY is a built-in keyword that after your WHERE clause that forces a comparison for an exact case-sensitive match.

As a side note, you can also make columns case-sensitive by adding the BINARY keyword when you create your table.
