Hi, I was able to get unique value without any duplicates using regular expression as "(?<=\,|^)(.+?)\,(?=(.+\,)?\1(\,|$))". For Example: `select regexp('abc,abc,123,000,123,000','(?<=\,|^)(.+?)\,(?=(.+\,)?\1(\,|$))','') from dual()` For more details, you can refer to [REGEXP](https://community.denodo.com/docs/html/browse/7.0/vdp/vql/appendix/syntax_of_condition_functions/text_processing_functions#regexp) section of the Virtual DataPort VQL Guide. Hope this helps!
