Dheeraj:

If you need the table, then there is no need to drop it. Is your previous experience with Oracle where it is faster to drop and create a table?

This is not the case with Teradata. The fastest thing that Teradata does is delete all of the rows from a table. So, instead of dropping and creating (which involves the data dictionary via deletes and inserts) do: DELETE Table-name;

If it fails ERRORCODE > 0, then do your CREATE TABLE. If it works, you are ready to load the table with the needed rows.

Hope this helps,
