Plz find error... ?? in pl/sql block...

Question

i couldn't able to run the query ... may i know where i have gone wrong... plz don't tell me the new solution... but rather find the wrong code in my program...
1 DECLARE
2 CURSOR cursor_list_tables_db IS
3 SELECT table_name FROM user_tables WHERE table_name LIKE upper('emp%');
4 row_count NUMBER ;
5 BEGIN
6 FOR rec IN cursor_list_tables_db LOOP
7 SELECT count(*) INTO row_count FROM rec.table_name;
8 DBMS_OUTPUT.PUT_LINE (rec.table_name || ' ' || row_count);
9 END LOOP ;
10* END ;
I even replace the line 7 as ....
EXECUTE IMMEDIATE 'SELECT count(*) FROM REC.TABLE_NAME' INTO row_count ;
but still getting the same error....i.e
PL/SQL: ORA-00942: table or view does not exist
Regards...

hi Jennesh ,
I am new to PL/SQL .
May I know Y
FOR rec IN cursor_list_tables_db LOOP
SELECT count(*) INTO row_count FROM rec.table_name;
is giving error
it is removed by
EXECUTE IMMEDIATE 'SELECT count(*) FROM '
||REC.TABLE_NAME INTO row_count ;
may i know the reason how it is recified . for the
first view it seems ok.
Thanks and Regads

DECLARE
CURSOR cursor_list_tables_db IS
   SELECT table_name
   FROM user_tables
   WHERE table_name LIKE upper('emp%');
row_count NUMBER ;
BEGIN
dbms_output.put_line('First syntax results in this query-- Second syntax results in this query:');
FOR rec IN cursor_list_tables_db LOOP
    dbms_output.put_line('SELECT count(*) FROM '|| rec.table_name||'---SELECT count(*) FROM  rec.table_name ');
END LOOP;
END;
First syntax results in this query-- Second syntax results in this query:
SELECT count(*) FROM EMP---SELECT count(*) FROM rec.table_name
SELECT count(*) FROM EMP1---SELECT count(*) FROM rec.table_name
SELECT count(*) FROM EMP2---SELECT count(*) FROM rec.table_name
PL/SQL procedure successfully completed.
