Tech Tip: Converting Legacy Date Fields to DB2 Web Query Dates, Part II

Available for Members and Guests. This is an off-site link.  Please review our Terms of Service (bottom of page) for additional information.

 Article Abstract:

(Gene Cobb) In my previous TechTip, "Converting Legacy Date Fields to DB2 Web Query Dates, Part I," I described how to use the powerful DB2 Web Query for IBM i built-in functions (BIFs) to convert your legacy date fields to "smart dates."
