UNSIGNED or BINARY?
Hi,

i'm making a MySQL database to run my website, and was wondering: what's the difference between the field types UNSIGNED and BINARY?

Thanks,
Corbb

The attribute UNSIGNED is changes the range of an integer type. For exampe the INT has this range: -2147483648 to 2147483647, but when it's marked as UNSIGNED, it will have this range: 0 to 4294967295

You use the BINARY attribute when you want to store binary data.. like f.ex. an image in the database
