Optional function not installed

I m new in clarion development. I’m tring to open a odbc table in my application and I receive the message ‘optional function not installed’. Please could anyone can help me

That is not an error I’ve seen before.
Can you give us some more context on what exactly you are doing when you receive the error?
What is the backend database?


Thank Rick
