Hello,
I have a spread sheet that has 300+ columns. I would like to create a loop that will select the data 1 column at a time without have to hand code the column name every time I want to select the next column. I have tried to use a variable but of course that does not work. Any help would be appreciated. This is my first post to this site so I apologize if I am asking in the wrong section.
Thank you.

You may think that you want to do this now, but IMHO you'd be better off coding the column names and selecting all of them at once. Otherwise the query will run dog slow.


My mantra: No loops! No CURSORs! No RBAR! Hoo-uh!

My thought question: Have you ever been told that your query runs too fast?

My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.


Need to UNPIVOT? Why not CROSS APPLY VALUES instead?
Since random numbers are too important to be left to chance, let's generate some!
Learn to understand recursive CTEs by example.
Splitting strings based on patterns can be fast!
