Hi list, I was wondering if it was possible for a field in SQL query to return NULL if latter value is exactly the same ? - for given ORDER BY clause, I guess. For example, query returns:
xxyy 1 4 true xxyy 5 7 true xxyy 21 8 true yyzz 5 1 false yyzz 7 7 false yyzz 8 34 false I'd like the output to be: xxyy 1 4 true NULL 5 7 NULL NULL 21 8 NULL yyzz 5 1 false NULL 7 7 NULL NULL 8 34 NULL Is there any magical trick to achieve this ? regards mk
