As a result MySQLdb has fetchone() and fetchmany() methods of cursor object to fetch records more efficiently. # Python SQL Select Statement Example import pyodbc conn = pyodbc.connect("Driver={SQL Server Native Client 11.0};" … c1.execute("select * from foo") Now I run a query on the second cursor: c2.execute("select * … 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 The Table Name (with a dbo schema) is: dbo.Person 4. PostgreSQLのdbを適当に作成し、テーブルとテストデータを入れる。, 次に名前付きカーソルで同様にSELECTしてみる。上との違いはcursor()に名前を与えただけである。, 次にMySQLdbのマニュアルで"server side cursor"と書かれているカーソルクラスを使って実験してみる。connect()にcursorclass=MySQLdb.cursors.SSCursorを引き渡すと有効になる。, ソースを読んでみるとソケットからデータ読み込まないことでブロックという驚愕の実装。コネクションレベルでブロックしていたら他の文が実行できないのではないだろうか?namesテーブルには2行入っているが、1行目を取得したあと、別途SELECTしたら何が起きるだろうか?, "you can't run this command now"だと。MySQL Connector(クライアントライブラリ)のマニュアルを完全には理解していないが、どうも結果を完全に読み切っていないため、同一スレッド中で次の文が実行できないような状態にあるらしい。他のスレッドからは読み込みは出来ても書き込みが出来ない状態になる。SSCursorは使い物にならない。, PostgreSQLでサーバーサイドカーソルと通常のカーソルを一つずつ使い。サーバーサイドカーソルを参照する。namesのテーブル内の'kenji'を'tomochi'に更新するという極簡単な例。.
