How to Handle MySQL\'s bit(1) Type with Go\'s bool?

MySQL's bit type handling in Go

When working with a MySQL database in Go using the beego ORM, one may encounter difficulties mapping the MySQL bit(1) type to an appropriate Go data type. This issue arises particularly when trying to utilize the bool type in Go for the corresponding column in the database.

In Go, using bool for MySQL's bit(1) columns results in errors like "strconv.ParseBool: parsing "x00": invalid syntax". To address this, Sqlx provides a custom bool datatype called BitBool specifically for such scenarios.

The BitBool type allows for efficient storage of boolean values in MySQL using the BIT(1) type, saving storage space compared to TINYINT. The Value() method of BitBool converts the bool value to a bitfield ([byte{1}] for true and [byte{0}] for false), while the Scan() method translates the incoming bitfield from MySQL into a BitBool value.

By using the BitBool type, developers can handle MySQL's bit(1) columns effectively in Go, avoiding storage bloat and ensuring compatibility with MySQL's data type without encountering errors.
