Hi Alll,
I have a fileupload control allows multiple files to upload. I should write a validation should not allow duplicate file names uploaded and should not be there in database too.
Does anyone had this situation. Your thoughts will highly help me.

you can save the file names in a rule input (check the array box). check if any matches occur, try looking at the array functions in documentation to see which one works for you. to check in the db, you can create a QE which returns the file name column and compare it with your values.
