Hey SQL users! Are you repeating the same query in every report? Are your queries getting too complicated? Organize them with recursive queries! Too many SQL reports can lead to clutter on your desktop and in your head. And is it really necessary to code each of them separately? Ad-hoc queries can share much of the same SQL code with managerial reports and even regulatory reports. Suppose you’ve been writing basic SQL queries for a while.
What happens when you combine CASE with SQL’s data modifying statements? Find out in this article. The CASE expression is a very useful part of SQL and one that you’ll employ frequently. We’ve already covered what the CASE expression does, how to format it, and how to use it in a SELECT statement in “Using CASE to Add Logic to a SELECT”. Another article, “How to Sort Records with the ORDER BY Clause” demonstrated how to use CASE in an ORDER BY clause.
