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].[GoogleSpanner].Customer (TotalDue) VALUES ('John')")
affected, _ := result.RowsAffected()

UPDATE

To retrieve updates:

result, _ := db.Exec("UPDATE [CData].[GoogleSpanner].Customer SET TotalDue = 'John' WHERE Name = '12345'")
affected, _ := result.RowsAffected()

DELETE

To delete updates:

result, _ := db.Exec("DELETE FROM [CData].[GoogleSpanner].Customer WHERE Id = '1'")
affected, _ := result.RowsAffected()
