I need to merge 7 datasets, monday, tuesday, wed, thur, friday, sat, and sun.

 

Use data set step is easy but I want to create a variable that I can identify whether those are from the dataset monday, or from sat, or from other dataset/

 

therefore, I am thinking to use "coalesce"

but I usually only merge two datasets, and never tried to merge seven together once.

 

the requriment is,

1) merge 7 at one time

2) create an index to identify where it is from, so in case there are ids same from monday and tue, I can still identify by looking at the index id.

any advice?

Thanks

Here's a recent question that has a viable approach:

That's assuming that MERGE means a SAS MERGE and not some other combination.

Thanks. Can you suggest an option with sql, since they are very large datasets?
