The following code examples show how to use data modification statements.

Procedure for Updates

You can use Exec to execute data modification statements. Exec returns a Result value which contains the number of affected rows.

INSERT

To insert updates:

result, _ := db.Exec("INSERT INTO Invoices (DueDate) VALUES ('John')")
affected, _ := result.RowsAffected()

UPDATE

To retrieve updates:

result, _ := db.Exec("UPDATE Invoices SET DueDate = 'John' WHERE Id = 'SENT'")
affected, _ := result.RowsAffected()

DELETE

To delete updates:

result, _ := db.Exec("DELETE FROM Invoices WHERE Id = '6'")
affected, _ := result.RowsAffected()
