Data format in a generic query

Question

My boss had given me a tough task. the requirement he gave me is:
Lets say select tname from tab;
EMP
DEPT
EMPSAL
i want the table name and the number of records in the table as in one row
Emp Dept EmpSAl
100 5 100
The output should come as 1 row with its result as second row. Is there anyway i can implement this?
I appreciate your quick reply on this..
Thank you

boss is crazy and he wants this report anyhowI think you are allowed to let the database go crazy for the sake of the crazy boss.
Write the output into a file using utl_file.
