CData ODBC Driver for Sybase IQ を使って、SAS からリアルタイムSybase IQ 連携レポートや分析を実施

CData ODBC Driver for Sybase IQ を使って、SAS からSybase IQ 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 Sybase IQ を合わせて使うことで、SAS からリアルタイムSybase IQ data へのアクセスが可能になります。本記事では、SAS でSybase IQ 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 Sybase IQ data in SAS due to optimized data processing built into the driver. When you issue complex SQL queries from SAS to Sybase IQ, the driver pushes supported SQL operations, like filters and aggregations, directly to Sybase IQ 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 Sybase IQ data in SAS.

Connect to Sybase IQ as an ODBC Data Source

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

SybaseIQ への接続には、User、Password、Server、Database のプロパティを設定します。TLS/SSL を有効化するには、UseSSL をTRUE に設定します。

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 Sybase IQ 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 SybaseIQ Sys]
Driver = CData ODBC Driver for Sybase IQ
Description = My Description
User = myuser
Password = mypassword
Server = localhost
Database = Northwind

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

Create a Sybase IQ Library in SAS

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

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

Create a View from a Sybase IQ 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 Sybase IQ data for reports, charts, and analytics.

Using the Query Tool

In SAS, click Tools -> Query
Select the table sources and the table(s) you wish to pull data from. Then, click OK.
Select columns and right-click to add filtering, ordering, grouping, etc.
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

In SAS, navigate to the Editor window.
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 products_view as
  select 
    productname, 
    price 
  from 
    odbclib.products 
  where 
    ProductName = 'Konbu';
quit;
```
Click Run -> Submit to execute the query and create a local view.

Report On or Visualize Sybase IQ Data in SAS

With a local view created, you can report, visualize, or otherwise analyze Sybase IQ 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

In SAS, navigate to the Editor window.
Use PROC PRINT to print an HTML report for the Sybase IQ Products data.
```
proc print data=products;
  title "Sybase IQ Products Data";
run;
```

Print a Chart

In SAS, navigate to the Editor window.

Use PROC GCHART to create a chart for the Products data.

proc gchart data=products;
  pie productname / sumvar=price
      value=arrow
      percent=arrow
      noheading
      percent=inside plabel=(height=12pt)
      slice=inside value=none
      name='ProductsChart';
run;
