Actually, I want to make the two big data sets have the same variable name list which is from the second file. Some variables in data file 1 need to be dropped. 

I think I should creat a name list from data 2 then select the data from data 1 according to this data 2 name list.

Can u tell me how to code in Stata?
Thanks
