I know the datatype is BINARY in mysql but what size do i need to make it? what do i fill in for the x?

BINARY(x)

Answer 1

According to this , you can predict the size of a md5.

If you don't want to, it seems like VARBINARY type is what you're looking for.

Answer 2

根据手册 ：

[...] the length for BINARY and VARBINARY is a length in bytes rather than in characters.
