DB2 9 and Microsoft Excel 2007 - Part 1: Getting the Data... - Page 2

6.  The Data Connection wizard opens. Select the table whose data you want to import into Excel 2007, and click Next. For example, you can select the contents of the STAFF table located in the SAMPLE database:

Note: To create the DB2 9 SAMPLE database, enter db2sampl from your operating system’s command prompt.

7.  Optionally, save that data connection (I'll refer to this as a database connection since that’s what it is), a great idea if you plan to reuse it, and click Finish:

If you don’t want to save this database connection in the future, you can simply click Finish in the previous step. In the previous figure, you can see that I’ve saved the current database connection (which is solely a connection to the STAFF table) for future reference. You can optionally add a description of this connection object (in the Description field) and search metadata (in the Search Keywords field) for easier subsequent retrieval. Finally, note that you have fine grained control over the authentication settings for this connection by clicking Authentication Settings.

8.  The Import Data window opens. Use this window to specify where the data should be placed in your Excel 2007 worksheet. Select the defaults for now, and click OK:

You can see in the previous figure that you can choose to place the data that is retrieved from DB2 9 in a Pivot Table report or chart, or both. I will discuss these options in my next article. (If you want to further configure this connection string’s properties, click Properties.)

Your Excel 2007 worksheet should now look similar to this:

Of course, at this point you can use the data as you see fit. For example, you can leverage Excel 2007’s strong formatting capabilities and apply a Table Style from the Design ribbon, for example:

You can also use the Table Style Options frame in the Design ribbon, like this:

When the data is loaded in Excel 2007, you can use the External Table Data frame in the Data ribbon to manage the database connection. For example, selecting Unlink will detach the data from the table and make it independent:

And you can quickly filter the returned data without writing a single line of SQL:

One of the things I love about Excel is its strong charting capability. Using this method, it’s very easy to whip up some snazzy charts with your DB2 9 data:

In the previous chart, you can see the ratio of salary to commission expenses for the 5 employees in department 20. Of course, so long as you didn’t disconnect the record set, you can refresh the data and the chart will be updated immediately. For example, run the following data manipulation language statement to drastically change the amount of commission Pernal makes (he’s employee 2 in the chart):

            UPDATE TABLE STAFF SET COMM=55565.56 WHERE ID=20

Now refresh the data:

And, of course, the base data is updated as well:

Now think back to the way most clients leverage Excel: by staging the data in a de facto data server. If your real-time data changed, when would be the next time your analysts would be analyzing real-time data? That’s right, after the next batch job!

Wrapping it Up...

In this article, I showed you how easy it is to import your DB2 9 data into an Excel 2007 worksheet. After getting the data into Excel 2007, I showed you some cool features that you can use to change the way the data is displayed (using different Table Tools ribbon frames) as well as how to create a chart and refresh the data in real time.
