Get all unique combinations of 2 columns from a table
3 views (last 30 days)
I have a table that has 4 variables, similar to this:
Item1 Item2 Item3 Item4
_____ _____ _____ _____
1 5 7 10
What is the best way to produce the delta of each combination of columns? Ex. Item1 vs Item2, Item1 vs Item3, etc.
