// Builder builds SQL in Dialect like MySQL, and PostgreSQL.
// The raw SQL and values are stored in Buffer.

// The core of gocraft/dbr is interpolation, which can expand ? with arbitrary SQL.
// If you need a feature that is not currently supported, you can build it
// on your own (or use Expr).
//
// To do that, the value that you wish to be expanded with ? needs to
// implement Builder.
