Updating 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 \"template1\".\"public\".Orders(ShipCity) VALUES ('New York')")
affected, _ := result.RowsAffected()

UPDATE

To retrieve updates:

result, _ := db.Exec("UPDATE \"template1\".\"public\".Orders SET ShipCity = 'New York' WHERE ShipName = 'USA'")
affected, _ := result.RowsAffected()

DELETE

To delete updates:

result, _ := db.Exec("DELETE FROM \"template1\".\"public\".Orders WHERE Id = '10261'")
affected, _ := result.RowsAffected()
