oracle - Get counts of all tables in a schema

Question

I am trying to get the record counts of all tables in a schema. I am having trouble writing the PL/SQL. Here is what I have done so far, but I am getting errors. Please suggest any changes:

DECLARE
v_owner varchar2(40);
v_table_name varchar2(40);

cursor get_tables is
select distinct table_name,user
from user_tables
where lower(user) = 'SCHEMA_NAME';


begin

open get_tables;
fetch get_tables into v_table_name,v_owner;

    INSERT INTO STATS_TABLE(TABLE_NAME,SCHEMA_NAME,RECORD_COUNT,CREATED)
    SELECT v_table_name,v_owner,COUNT(*),TO_DATE(SYSDATE,'DD-MON-YY') FROM         v_table_name;

CLOSE get_tables;

END;

This can be done with a single statement and some XML magic:

select table_name, 
       to_number(extractvalue(xmltype(dbms_xmlgen.getxml('select count(*) c from '||owner||'.'||table_name)),'/ROWSET/ROW/C')) as count
from all_tables
where owner = 'FOOBAR'
