Answer / prabhudatta barick

Automatic Optimizer Statistics Collection
By default Oracle 10g automatically gathers optimizer
statistics using a scheduled job called GATHER_STATS_JOB.

As it gathers table statistics automatically
so no need to gather table statistics before
running this query.

SELECT num_rows
FROM dba_tables
WHERE table_name = '<TABLE_NAME>';

This will give u the total no. of records in a table....
