Thanks Graham for your answer.
University talk. (not a pun).
PictureColumn is a Type implementation you find in Xojo.
Also, RecordSet and DatabaseRecord are unknow @ sqlite.com
At last, I (try to) program in Xojo and this is not an easy task even with nearly 40 years in this business.
Before I forgot: I will (tomorrow 'cause it is too late for today 50 minutes to midnight) try your code. Thanks.
