Modifying Data
The connection is also used to issue INSERT, UPDATE, and DELETE commands to the data source. If desired, parameters can be used with these statements. The provider does not support transactions. Any SQL statements executed by this connector will affect the data source immediately. The commit() method on the connection object should not be used.
Insert
The following example adds a new record to the table:
cmd = "INSERT INTO Accounts (Name, Industry) VALUES (?, ?)" params = ["Manufacturing", "Chemicals"] cur = conn.execute(cmd, params) print("Records affected: ", cur.rowcount)
Update
The following example modifies an existing record in the table:
cmd = "UPDATE Accounts SET Industry = ? WHERE Id = ?" params = ["Chemicals", "1"] cur = conn.execute(cmd, params) print("Records affected: ", cur.rowcount)
Delete
The following example removes an existing record from the table:
cmd = "DELETE FROM Accounts WHERE Id = ?" params = ["1"] cur = conn.execute(cmd, params) print("Records affected: ", cur.rowcount)
