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 INVOICES (InvoiceNumber) VALUES ('John')")
affected, _ := result.RowsAffected()

UPDATE

To retrieve updates:

result, _ := db.Exec("UPDATE INVOICES SET InvoiceNumber = 'John' WHERE InvoiceId = 'NewTech Industries'")
affected, _ := result.RowsAffected()

DELETE

To delete updates:

result, _ := db.Exec("DELETE FROM INVOICES WHERE Id = '1894553000000026007'")
affected, _ := result.RowsAffected()
