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 Contact (Name) VALUES ('John')")
affected, _ := result.RowsAffected()

UPDATE

To retrieve updates:

result, _ := db.Exec("UPDATE Contact SET Name = 'John' WHERE SalesPerson = 'U.S.A.'")
affected, _ := result.RowsAffected()

DELETE

To delete updates:

result, _ := db.Exec("DELETE FROM Contact WHERE Id = '1'")
affected, _ := result.RowsAffected()
