Types

type DB

type DB interface {
	Querier
	BeginTxx(ctx context.Context, opts *sql.TxOptions) (Tx, error)
	Close() error
}

DB wraps sqlx.Tx and sqlx.DB https://github.com/jmoiron/sqlx/issues/344#issuecomment-318372779

	Df      string
	Conf    config.DbConfig

type GddDB

type GddDB struct {
	*sqlx.DB
}

GddDB wraps sqlx.DB

func (*GddDB) BeginTxx

func (g *GddDB) BeginTxx(ctx context.Context, opts *sql.TxOptions) (Tx, error)

BeginTxx begins a transaction

type GddTx

type GddTx struct {
	*sqlx.Tx
}

GddTx wraps sqlx.Tx

type Querier

type Querier interface {
	NamedExecContext(ctx context.Context, query string, arg interface{}) (sql.Result, error)
	ExecContext(ctx context.Context, query string, args ...interface{}) (sql.Result, error)
	GetContext(ctx context.Context, dest interface{}, query string, args ...interface{}) error
	Rebind(query string) string
	SelectContext(ctx context.Context, dest interface{}, query string, args ...interface{}) error
}

Querier common operations for sqlx.Tx and sqlx.DB

type Tx

type Tx interface {
	Querier
	Commit() error
	Rollback() error
}

Tx transaction
