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 Customers (Name) VALUES ('Hook, Captain')") affected, _ := result.RowsAffected()
UPDATE
To retrieve updates:
result, _ := db.Exec("UPDATE Customers SET Name = 'Hook, Captain' WHERE Id = 'Cook, Brian'") affected, _ := result.RowsAffected()
DELETE
To delete updates:
result, _ := db.Exec("DELETE FROM Customers WHERE Id = '10456255-0015501366'") affected, _ := result.RowsAffected()
