The most accurate way would be to do
select count(*) from table
but that might be slow if your table is ~100GB in size. You can
still make a query to USER_TABLES or DBA_TABLES and there is a column
called NUM_ROWS which tels you how many rows did the table have when it
was last analyzed.

Hi,
Analyze all the tables and select num_rows from dba_tables. Hope this helps
you.

All,
Is there an easy way to find out how many rows are
there is each table for a schema?
Run the following script:
-
Aim : TIP for "find out the no. of rows in each tables in user's
schema"
--Date: 19th May, 2000
--Author: Ramesh Papnoi
--Subject : TIP for finding out the no. of rows in each tables
in User's Schema on which user
Or if your tables are all analyzed and you want a rough answer (faster but
less accurate)
select table_name , num_rows from dba_tables where owner='&schema';
You might want to round the num_rows.
Again, only as good as the last analyze - when it was done and estimate vs
compute.

Analyze the tables, then look at num_rows in dba_tables.
