Hi,
Like to check if there is a SQL expression to check if the string sequence/array is empty? I need to do content filtering such that if either a particular string exists in the sequence/array or if the sequence/array is empty, I should allow the data to go through. Thank you.
Sorry to say, there is no way to test for the length of a sequence in the SQL filter expression. I suggest that you use a dummy string so that the sequence is never really empty. So, you can test for the presence of the particular string or the dummy string to pass the filter.
Ok, thanks, would use that method for now.
