Help us understand the problem. PythonでDBを操作するときに出てくるcursorについて、あまりにも実体不明なので調べた。SQL CURSORとPython cursorの違い、SQL CURSORをどれだけ忠実に実装しているか、という視点でPostgreSQL用のpsycopg2とMySQL用のMySQLdbについて調査した。, PostgreSQL用のpsycopg2では名前付きカーソルを宣言するとサーバーサイドになる。名前なしではクライアントサイドになる。, サーバーサイドカーソル("SSC")とPythonのメソッドの関係は次のとおり。クライアントサイドカーソル("CSC")では特記のない限り使えない。, カーソルはSELECT文などのクエリの結果を1行ずつ逐次取得したり、前後の行に移動したりすることができる。また現在行を他のSQL文から参照することもできる。なお文法の解説が目的ではないので詳細は省略。, カーソルの次の行を取得するには、次のような文を実行する。通常方向はNEXTまたはFORWARDで先に進みながら行を取得する。途中で戻ることも可能で、その場合はPRIORまたはBACKWARDを指定する。先頭FIRSTや末尾LASTに一気に移動することも可能である。, カーソル行を他の文から参照することもできる。これをやるとSELECTの結果を利用しながら他の操作を行うことが簡単にできる。例えばあるカーソルが現在取得済みの行を参照するには次のようにCURRENT OFを使う。, cursorはコネクションオブジェクトの.cursor()メソッドを呼ぶことで作成する。トランザクションはコネクションオブジェクトに対して働くため、一つのコネクションオブジェクトから複数のカーソルを作成した場合、それらは一つのトランザクション内で実行される。, Python cursorがSQL CURSORを宣言、利用しているのか実験して確かめる。方法は A pure Python client for the SAP HANA Database based on the SAP HANA Database SQL Command Network Protocol.. pyhdb supports Python 2.7, 3.3, 3.4, 3.5 and also PyPy on Linux, OSX and Windows. In fact I played around with SQLite3 (included in Python) where the API supports a generator: where I'm getting an "DPI-1001: out of memory" in cx for breaching a GB I only got some 370MB for the generator-based executemany in sqlite3. 1, if the cursor has been closed, or 0, otherwise. PyODBC is the Python package for ODBC. Cursor type.
