MySQL Functions : Convert a value to a binary string
The BINARY function converts a value to a binary string.
This function is equivalent to using CAST(value AS BINARY).

|---|
Here MySQL performs a character-by-character comparison of "HELLO" and "hello" and return 1 (because on a character-by-character basis, they are equivalent):
SELECT "HELLO" = "hello";
Here MySQL performs a byte-by-byte comparison of "HELLO" and "hello" and return 0 (because on a byte-by-byte basis, they are NOT equivalent):
SELECT BINARY "HELLO" = "hello";
