Modifying Data
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()
