I observe that your SQL query is syntactically wrong (closing double quote)
and the FROM clause is missing, but apart from that it should work fine.
Could it be that there are spaces or other invisible characters in the "result" attribute?
What do you get for
SELECT DISTINCT '|' || result || '|' FROM <table> WHERE result <> 'PASS';
