Real Life Query Examples The IIRSLQ02 member in the sample library (hlq.CIMTSAMP) provides the following examples of "real-life" SQL queries. First, let's deal with data that isn't quite as pretty as the data above. He has written several books, including Joe Pluta introduces you to EGL Rich UI and IBM’s Rational Developer for the IBM i platform.Discover incredibly powerful WDSC with this easy-to-understand yet thorough introduction.Quickly get up to speed and productivity using Eclipse. The MySQL is also one of the popular database management system which is used by mid-level companies in their products.
In a join, you combine columns (fields) from one table (file) with columns from another file. At a high level, we can also identify patterns and trends in our data.For this, we will use a collection of built-in functions in SQL, that summarize, or roll-up, our values. So you can see that in this file there are currently two records for ITEMA, with a total quantity of 12.000. Yours could even be slowing you down. While SQL does a very good job within the confines of the 24x80 green-screen paradigm, the graphical assistance capabilities of the Eclipse product line show through pretty well.Here, for example, is the wizard-generated Data Definition Language (DDL) source for a file that was created using DDS source and the standard CRTPF command:This is pretty impressive.
This means they could ask us to update each entry of ‘Nokia’ to ‘Nokia Lumia’, and ‘Samsung’ to ‘Samsung S5’.

The better news is that this article will show you some practical examples on how to use those tools.Please note that this article is specifically about interactive SQL.

Real-Life Database Examples To say that the databases are everywhere would be an understatement.
I would like to explain different MySQL queries which are really used in day-to-day activities in the industry. Transformations are also needed to present data reports in a more human-readable format.Following are some examples for the quarterly and monthly Sales report, using built-in functions:The first query displays a quarterly Sales report. However, the first thing I would see is an error message stating "Duplicate table designator CUSMAS not valid." As you need more formatting in your SQL, you need more verbiage, and SQL is nothing if not verbose.

In my previous articles I have explained different SQL Queries with real life examples. Please note that this article is specifically about interactive SQL.
What if you need more information, such as in this particular case the number of records for a given item or the total quantity? Let's show the distinct values for item numbers in the example: Use these queries as templates to create custom reports or execute them without any change.
