Simple example to database transaction with golang

Tx

Transactions enforce the integrity of the database and guard the data against program errors or database break-downs [=>].

How to use

Wrap your transaction inside Wrap function. It determine between Rollback() and Commit() . See example below:

package main

func main() {
	// ... some codes
	tx : tx.NewTx(db)
	err := tx.Wrap(createUserAndRole)
	if err != nil {
		log.Fatal(err)
	}
	// ... some codes
}

// This our needs
func createUserAndRole(t Transaction) (err error) {
	res, err := t.Exec("INSERT INTO users(name,email) VALUES(?,?)", "example", "[e-mail]")
	if err != nil {
		return
	}

	userId, err := res.LastInsertId()
	if err != nil {
		return
	}

	res, err = t.Exec("INSERT INTO role(user_id,privileges) VALUES(?,?)", userId, "SELECT,INSERT")
	if err != nil {
		return
	}

	return
}
