It sounds like you want the id values for three distinct columnx values. Is this right? Try this.
To be honest I'm not sure what you are asking either but it sounds like you want to return the ids for those rows where there are duplicate values in columnx (limit the result to 3).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
