LIGHTLY TECHNICAL OBSERVATIONS ON PEOPLESOFT, SQR, AND RELATED AND UNRELATED TOPICS

One day, while typing "AND JOB.EFFDT = (SELECT MAX(EFFDT)" for about the 10,000th time, it suddenly occurred to me that I had already typed that about 10,000 times and maybe I should save the SQL for future use. Now, I consider myself fairly intelligent and creative, but sometimes the obvious escapes me. Turns out that it really is quicker to cut, paste and modify than to recode from scratch each time!

OK, please stop laughing. My real purpose today is to give a suggestion for what a template for common HRMS queries might look like. So here's a sample you might want to start with. Before using it, it's important that you review it first. For example, if you are not using EMPL_RCD for separate jobs, you should include "EMPL_RCD=0" to improve performance. This sample is best for the older releases (up to 8.3). At newer releases, you might want to drop the EMPLOYMENT reference and decide whether to rely on PERSONAL_DATA or to use the "live" tables instead. Also, decide whether you can rely on the SETID_ fields in JOB, or they are not always accurate (the subject of a previous post) and you prefer to go through the set control tables. And is "ALPS" what you consider a complete list of active codes? Or just rewrite the whole thing in your preferred style. Your mileage may vary—you get the idea. After your review and testing are complete, hopefully you'll have a good base to use for a large percentage of your future ad hoc queries.
