BLOB is physically in the database. The datalink is a pointer to your IFS, or other server, file. We use a datalink to reference engineering drawings for a web based application.

Whoa, I think I need to know more about this DATALINK. We have a need in the near future to reference photos, drawings, signatures that will be stored in the IFS and link them to a particular record in the native database. Or should I say, the native file record will have links to the IFS objects. Without fully recognizing all of the capabilities, the only function I could see using this for would be to automatically pop up a photo/drawing/signature in Windows when a user hits a function key on a green-screen app (F9=Show mug shot). However, looking through the archives, I have to wonder how stable this is. In http://archive.midrange.com/midrange-l/200203/msg02072.html, Richard Theis of IBM shows what appear to be several complex steps to set up and then adds "Sometimes, it works !" He provides a reference that I have yet to look at, but if it is typical of most IBM manuals, it won't give any "how to" advice. I guess I'm still unclear about the difference between a BLOB and a DATALINK. Anyone feel like taking a stab? tia, db -- This is the Midrange Systems Technical Discussion (MIDRANGE-L) mailing list To post a message email: MIDRANGE-L@xxxxxxxxxxxx To subscribe, unsubscribe, or change list options, visit: http://lists.midrange.com/mailman/listinfo/midrange-l or email: MIDRANGE-L-request@xxxxxxxxxxxx Before posting, please take a moment to review the archives at http://archive.midrange.com/midrange-l.
