python DB API - fetchmanyを使用したリスト変換

Question

あるデータベースサーバーからデータをフェッチして別のデータベースサーバーにロードしようとしています。私は2つのカーソルを開いていて、1つのカーソルにデータをフェッチして、結果をプリペアして2番目のカーソルに "executemany" INSERTステートメントを実行します。

"executemany"を実行するための結果をそのまま使用できません。リストへの変換、リストへのコピーなどを試みましたが、何も動作していないようです。しかし、手動で結果をクリップボードにコピーし、リストとして再度ペーストすると、INSERTが機能します。私はここで何が欠けているか分からない。以下

>>> scur.execute("select top 3 * from db1.dbo.job") 
<pyodbc.Cursor object at 0x7f9c2a1b2930> 

>>> rows = scur.fetchall() 

>>> rows 
[(1127, u'', u'8196660', u'', u'', 0, u'', u'', None, 35, None, 0, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, u'', 0, None, None), (1128, u'', u'8196638', u'', u'', 0, u'', u'', None, 23, None, 0, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, u'', 0, None, None), (1129, u'', u'8195737', u'', u'', 0, u'', u'', None, 22, None, 0, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, u'', 0, None, None)] 
>>> icur.executemany(stmt1, rows)
