Hi Brian. That's what actually I was trying to build in order to get it. I was thinking about 2 nested query. The inner one just sorting the output, something like: SELECT * FROM huge_table ORDER BY a_column_of_huge_table ASC The outer would compare for example the current tuple with the following one and as you said "If it finds an index such that a[i] > a[i+1], you know the result isn't sorted correctly." Could you please write to me a sort of "what should that nested query be", please? Remark I'm not a database user and SQL is not that fresh to me. Thank you Brian! > My advice would be to write a quick application that creates a cursor of > the sorted results, and sucks them out.
