	NamedExecContext(context.Context, string, interface{}) (sql.Result, error)
	QueryRowxContext(context.Context, string, ...interface{}) *sqlx.Row
	NamedQueryContext(context.Context, string, interface{}) (*sqlx.Rows, error)
	GetContext(context.Context, interface{}, string, ...interface{}) error
	BeginTxx(context.Context, *sql.TxOptions) (*sqlx.Tx, error)
}

Database provides a database interface
