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 [CData].[Sample].Customers(CompanyName) VALUES ('Caterpillar')")
affected, _ := result.RowsAffected()

UPDATE

To retrieve updates:

result, _ := db.Exec("UPDATE [CData].[Sample].Customers SET CompanyName = 'Caterpillar' WHERE City = 'US'")
affected, _ := result.RowsAffected()

DELETE

To delete updates:

result, _ := db.Exec("DELETE FROM [CData].[Sample].Customers WHERE _id = '22'")
affected, _ := result.RowsAffected()
