Types

type Driver

type Driver interface {
	ExecQuerier
	// Tx starts and returns a new transaction.
	// The provided context is used until the transaction is committed or rolled back.
	Tx(context.Context) (Tx, error)
	// Close closes the underlying connection.
	Close() error
	// Dialect returns the dialect name of the driver.
	Dialect() string
}

type ExecQuerier

type ExecQuerier interface {
	// Exec executes a query that doesn't return rows. For example, in SQL, INSERT or UPDATE.
	// It scans the result into the pointer v. In SQL, you it's usually sql.Result.
	Exec(ctx context.Context, query string, args, v interface{}) error
	// Query executes a query that returns rows, typically a SELECT in SQL.
	// It scans the result into the pointer v. In SQL, you it's usually *sql.Rows.
	Query(ctx context.Context, query string, args, v interface{}) error
}

ExecQuerier wraps the 2 database operations.

type Tx

type Tx interface {
	ExecQuerier
	driver.Tx
}

Tx wraps the Exec and Query operations in transaction.

func NopTx

func NopTx(d Driver) Tx

NopTx returns a Tx with a no-op Commit / Rollback methods wrapping the provided Driver d.
