Check the SQL produced by your $execdirect, see if it is valid.  I've sometimes found an $execdirect will not work where a $prepare and $execute will, so maybe try that combination.

It has made me realize that I need to get my app to be able to be used via the web. I want to make it a two step process by providing a JS Form subset of the windows of the desktop app for the outside sales staff that will be able to have read/write access to the Omnis Datafile .df1, and then work on converting the rest of the app to SQL, etc.

I can do selects and inserts, and the inserts are nicely reflected in the Omnis data file as shown on the desktop windows. BUT, I am having a problem in getting an update to work. I have tried using the prebuilt $update() method (it returns flag True), I have tried creating a Statement object and using various permutations of the $execdirect method (they return flag False).
