append different aggregating results of columns into one table?
hi,
I want to calculate some average, median, max, min etc. (those that are not in the metadata results) of the data in one table,
I use several aggregate operators on that dataset to do this, and then append the results. However, the Append operator is complaining, that column names or so are not matching, but the column number is matching, I just want to append them no matter what the columns are. Is that anyhow possible?

You can also use "rename by generic names" if you know they really are the same and then simply rename them after.
Hello
The Append operator requires the attribute names to be identical in all the example sets. In your case, the names will all be different. Perhaps you want to Join the attributes instead? Here's an example that might help...
