I am trying to convert data to a new db. I have one column where the data is either 'Y' or 'N'.

I need to change all the 'Y' to 'N'
and
change all the 'N' to 'Y'

I would like to do this in a sproc, I will be doing this nightly, but when I do my updates it changes them all to 'N'

Please help!

Either Use Temp table or
First Update Y to Z, N to Y then Z to N

This should do it in one update stetement.


Update MyTable
set
	MyCol =	case MyCol
		when 'Y' then 'N'
		when 'N' then 'Y'
		else MyCol
where
	MyCol in ('Y','N')
