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

UPDATE

To retrieve updates:

result, _ := db.Exec("UPDATE Contacts SET Name = 'John Doe' WHERE Discount = 'ACTIVE'")
affected, _ := result.RowsAffected()

DELETE

To delete updates:

result, _ := db.Exec("DELETE FROM Contacts WHERE ContactId = 'c27221d7-8290-4204-9f3d-0cfb7c5a3d6f'")
affected, _ := result.RowsAffected()
