How to Efficiently Concatenate SAS Datasets with Varying Column Names?

[anarose192]

I'm currently working on a project in SAS Studio and SAS on demand, and I need to concatenate multiple datasets with varying column names. I've come across several approaches, but I'm looking for the most efficient method. Could someone kindly guide me through the steps or share any code snippets that can help me achieve this seamlessly? Your expertise would be greatly appreciated!

Please describe your situation in more detail. Do you have different names for the same variable, or should end the variables up side-by-side, with missing values for the datasets where they were not present?

By efficient, do you mean the time it would take to write the program?

If your variables that you want to be in the some output variable have the same positions in the input data sets, you can use the UNION ALL operator in SQL, since it doesn't care about variable names (except the one from the first table).
