Solutions are easy. Understanding the problem, now, that's the hard part.

So you want to udpate data based on the name of a column? Is that right?

you could try something like


UPDATE Employees
SET Day1= '0'
WHERE (isnumeric(Day1) =1)

UPDATE Employees
SET Day1= '#'
WHERE (isnumeric(Day1) <>1)



but from the brief look at your table it looks like you have some flaws in your Db design, you could maybe improve it with better tables design and some normalisation.
