Reuse Your RPG Code with SQL User-Defined Functions

Recently, one of our programmers came to me with a question about retrieving some information from our iSeries. He was using a business intelligence (BI) tool to analyze picking errors across several warehouses, and he needed a way of retrieving the warehouse area for a specific warehouse and item location. Unfortunately, that information was not in a table in our system, but rather was calculated by an RPGLE program and returned as a parameter when the program was called with the warehouse ID and the item location. Because the BI tool used SQL to retrieve information from our iSeries, I suggested that he consider creating an SQL User-Defined Function (UDF) to return the warehouse area. With this method, the warehouse area can be returned as a value by any high-level language, such as PHP or Java, or any tool that uses SQL to access data on the system.
