MySQL and MariaDB store a UUID as 16 raw bytes in a `binary(16)` column, so `prepareValue()` converts the canonical form with `DbUuidHelper::uuidToBlob()` and binds it as `DataType::LOB`. Requires yiisoft/db#1199.

There was a problem hiding this comment.
Will it work when $expression->value is 16 raw bytes or 32 hexadecimal characters? Needs a test
