Displaying RowID in Select * (all) Statement

Question

I am trying to display the RowID alongside all columns from a Select * statement.

I am using Oracle with Toad to run the SQL statement.

I have two tables that I need to compare, but I do not have any unique identifiers to use when sorting the two tables for comparison. So I thought that using the RowID to sort the two tables in order to compare them could help.

Is there a way to add RowID to a Select * statement? I cannot add all the columns names as there are over 50 of them. I will be doing this to multiple sets of tables where the number and name of columns will vary.

Any help or ideas around this would be greatly appreciated.

Thanks in advance,

Answer 1

You can do something like

SELECT rowid, a.*
  FROM table_name a

But I'm not sure that is actually going to help you. Sorting the data on ROWID is not going to be particularly useful since that is just a physical location on disk. It's just as arbitrary as presenting the data unsorted.
