I need to understand what does TOP actually mean?
SELECT TOP 5 from TABLE1;
The above will fetch me 5 rows. However I don't understand what did Teradata use to determine the top 5 rows as I have not put any 'ORDER BY' clause.
Then with which column(s) did it do the sort?
Should it fetch me the same rows always?
Thanks in advance.
