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 Orders(Total) VALUES ('John')") cnxn.commit() affected = cursor.rowcount
To retrieve updates:
cursor.execute("UPDATE Orders SET Total = 'John' WHERE ParentId = '3'") cnxn.commit() affected = cursor.rowcount
To delete updates:
cursor.execute("DELETE FROM Orders WHERE Id = '6'") cnxn.commit() affected = cursor.rowcount
