CData ODBC Driver for MySQL を使って、SAS からリアルタイムレポートや分析を実施。

CData ODBC Driver for MySQL を使って、SAS からMySQL data データを連携利用。

SAS は、高度なアナリティクス、BI、データ管理、予測分析のためのソフトウェアです。SAS とCData ODBC Driver for MySQL を合わせて使うことで、SAS からリアルタイムMySQL data へのアクセスが可能になります。本記事では、SAS でMySQL のライブラリを作成し、データベースのようにデータを扱い、レポートを作成します。

The CData ODBC Driver offers unmatched performance for interacting with live MySQL data in SAS due to optimized data processing built into the driver. When you issue complex SQL queries from SAS to MySQL, the driver pushes supported SQL operations, like filters and aggregations, directly to MySQL and utilizes the embedded SQL engine to process unsupported operations (often SQL functions and JOIN operations) client-side. With built-in dynamic metadata querying, you can easily visualize and analyze MySQL data in SAS.

Connect to MySQL as an ODBC Data Source

Information for connecting to MySQL follows, along with different instructions for configuring a DSN in Windows and Linux environments (the ODBC Driver for MySQL must be installed on the machine hosting the SAS System).

The Server and Port properties must be set to a MySQL server. If IntegratedSecurity is set to false, then User and Password must be set to valid user credentials. Optionally, Database can be set to connect to a specific database. If not set, tables from all databases will be returned.

When you configure the DSN, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

Windows

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Linux

If you are installing the CData ODBC Driver for MySQL in a Linux environment, the driver installation predefines a system DSN. You can modify the DSN by editing the system data sources file (/etc/odbc.ini) and defining the required connection properties.

/etc/odbc.ini

[CData MySQL Sys] Driver = CData ODBC Driver for MySQL Description = My Description User = myUser Password = myPassword Database = NorthWind Server = myServer Port = 3306

For specific information on using these configuration files, please refer to the help documentation (installed and found online).

Create a MySQL Library in SAS

Connect to MySQL in SAS by adding a library based on the CData ODBC Driver for MySQL.

  1. Open SAS and expand Libraries in the Explorer pane.
  2. In the Active Libraries window, right-click and select New.
  3. Name your library (odbclib), select ODBC as the Engine, and click to Enable at startup (if you want the library to persist between sessions).
  4. Set Data Source to the DSN you previously configured and click OK.

Create a View from a MySQL Query

SAS natively supports querying data either using a low-code, point-and-click Query tool or programmatically with PROC SQL and a custom SQL query. When you create a View in SAS, the defining query is executed each time the view is queried. This means that you always query live MySQL data for reports, charts, and analytics.

Using the Query Tool

  1. In SAS, click Tools -> Query
  2. Select the table sources and the table(s) you wish to pull data from. Then, click OK.
  3. Select columns and right-click to add filtering, ordering, grouping, etc.
  4. Create a local view to contain the query results by right-clicking the SQL Query Tool window, selecting Show Query, and clicking Create View. Name the View and click OK.

Using PROC SQL

  1. In SAS, navigate to the Editor window.
  2. Use PROC SQL to query the data and create a local view.
    NOTE: This procedure creates a view in the Work library. You can optionally specify a library in the create view statement.
    proc sql;
      create view orders_view as
      select 
        shipname, 
        freight 
      from 
        odbclib.orders 
      where 
        ShipCountry = 'USA';
    quit;
    
  3. Click Run -> Submit to execute the query and create a local view.

Report On or Visualize MySQL Data in SAS

With a local view created, you can report, visualize, or otherwise analyze MySQL data using the powerful SAS features. Print a simple report using PROC PRINT and create a basic graph based on the data using PROC GCHART.

Print an HTML Report

  1. In SAS, navigate to the Editor window.
  2. Use PROC PRINT to print an HTML report for the MySQL Orders data.
    proc print data=orders;
      title "MySQL Orders Data";
    run;
    

Print a Chart

  1. In SAS, navigate to the Editor window.
  2. Use PROC GCHART to create a chart for the Orders data.
    proc gchart data=orders;
      pie shipname / sumvar=freight
          value=arrow
          percent=arrow
          noheading
          percent=inside plabel=(height=12pt)
          slice=inside value=none
          name='OrdersChart';
    run;
