Modifying 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 [CData].[Entities].Customers (CompanyName) VALUES ('Caterpillar')") affected, _ := result.RowsAffected()
UPDATE
To retrieve updates:
result, _ := db.Exec("UPDATE [CData].[Entities].Customers SET CompanyName = 'Caterpillar' WHERE City = 'US'") affected, _ := result.RowsAffected()
DELETE
To delete updates:
result, _ := db.Exec("DELETE FROM [CData].[Entities].Customers WHERE _id = '22'") affected, _ := result.RowsAffected()
