Hello
The query works well for me
SQL> select * from t1;
NAME      VALUE
divya        10
deepa        11
SQL> select * from t2;
NAME      VALUE
deepa        11
divya        20
divya        22
SQL> select t1.name,t1.value,t2.value
  2  from t1,t2
  3  where t1.name=t2.name and t1.value != t2.value;
NAME      VALUE     VALUE
divya        10        20
divya        10        22If this is not what you want, then explain with some sample data
