Retrieving Distinct Rows from a Table in SQL Server: A Solution Using Common Table Expressions (CTEs)
Understanding the Problem and Requirements The problem at hand is to retrieve distinct rows from a table based on two specific columns (Num1 and Num2) while considering a third column (Range). The twist here is that the order of values in these two columns matters, i.e., (A, B) should be treated as equivalent to (B, A), but if there are multiple rows with the same highest range for both permutations, we only want one of them.
