Number of records in each partition

Question

Hi,
Can any one please tell me, how to display number of record in each partion in any table.
I wanted to use following in PL/SQL but it gives me error.
Declare
Cursor c1 is
select partition_name into part_name from all_tab_partition where table_name = 'table_name';
BEGIN
for rec in c1
Loop
select count(*) into temp_var from table_name partition(rec.part_name)
END LOOP;
END;
I guess I need dynamic SQL ..
Any thoughts on this ??
Thanks,
Av

It is always better to analyze the tables and get these details from num_rows as mentioned before but just in case you want the latest information from the table dynamically then use the following
Declare
Cursor c1 is
select table_name,partition_name from all_tab_partitions where table_name = 'SALESDETAILS';
v_sql varchar2(2000);
temp_var number:=0;
BEGIN
for rec in c1
Loop
execute immediate 'select count(*) from '||rec.table_name||' partition('||rec.partition_name||')' into temp_var;
dbms_output.put_line('The Partition '||rec.partition_name||' of table '||rec.table_name||' has '||temp_var||' rows');
END LOOP;
END;
