Peart said, 'When you choose not to decide, you still have made a choice. If you just list the ungrouped columns, the DBMS will either throw an error (Oracle does that - the right choice, imo) or pick one value more or less at random (MySQL). You could add them up: SELECT a,b, SUM(c) 'tot' FROM V GROUP BY a,b You could add pick the smallest value: SELECT a,b, MIN(c) 'first' FROM V GROUP BY a,b Or you could take the mean (AVG), the standard deviation (STD), and any of a bunch of other functions that take a bunch of values for c and combine them into one.What isn't really an option is just doing nothing. You could discard column c as unimportant: SELECT DISTINCT a,b FROM V Or you could perform some kind of aggregation on them.
