The following code examples show how to use data modification statements.
Procedure for Updates
You can use execute method to execute data modification statements. This will update the cursor's rowcount property with the number of affected rows.
Note that you must commit the connection after performing the modification, or your changes may be lost.
To insert updates:
cursor.execute("INSERT INTO Customers(Company) VALUES ('John')") cnxn.commit() affected = cursor.rowcount
To retrieve updates:
cursor.execute("UPDATE Customers SET Company = 'John' WHERE CompanyName = 'CompanyName'") cnxn.commit() affected = cursor.rowcount
To delete updates:
cursor.execute("DELETE FROM Customers WHERE Id = '12345'") cnxn.commit() affected = cursor.rowcount
