PyCharm でCData ODBC Driver for MarkLogic を使ってみた

MarkLogic にODBC データソースとしてPyCharm から連携。

CData ODBC Drivers は、ODBC をサポートするあらゆる環境から利用可能です。 本記事では、PyCharm からのCData ODBC Driver for MarkLogic の利用を説明します。ODBC Deriver をデータソースとして設定する方法、データソースをクエリするPyCharm のベーシックな方法を含みます。

To begin, this tutorial will assume that you have already installed the CData ODBC Driver for MarkLogic as well as PyCharm.

Pyodbc をプロジェクトに追加

Follow the steps below to add the pyodbc module to your project.

  1. Click File -> Settings to open the project settings window.
  2. Click Project Interpreter from the Project: YourProjectName menu.
  3. To add pyodbc, click the + button and enter pyodbc.
  4. Click Install Package to install pyodbc.

MarkLogic への接続

You can now connect with an ODBC connection string or a DSN. See the Getting Started section in the CData driver documentation for a guide to creating a DSN on your OS.

Set User, Password, and Server to the credentials for the MarkLogic account and the address of the server you want to connect to. You should also specify the REST API Port if you want to use a specific instance of a REST Server.

Below is the syntax for a DSN:

[CData MarkLogic Source] Driver = CData ODBC Driver for MarkLogic Description = My Description User = 'myusername' Password = 'mypassword' Server = 'http://marklogic'

MarkLogic へのクエリの実行

Instantiate a Cursor and use the execute method of the Cursor class to execute any SQL statement.

import pyodbc cnxn = pyodbc.connect('DRIVER={CData ODBC Driver for MarkLogic};User = 'myusername';Password = 'mypassword';Server = 'http://marklogic';') cursor = cnxn.cursor() cursor.execute("SELECT Name, TotalDue FROM Customer WHERE Id = '1'") rows = cursor.fetchall() for row in rows: print(row.Name, row.TotalDue)

After connecting to MarkLogic in PyCharm using the CData ODBC Driver, you will be able to build Python apps with access to MarkLogic data as if it were a standard database. If you have any questions, comments, or feedback regarding this tutorial, please contact us at support@cdata.com.
