Hi,
i have table1 with "name varchar2(100)" as column and has 100 records
i have another table table2 with "name varchar2(100)" as column and has 150 records.

If i give
select count(t1.name) from table1 t1,table2 t2
where t1.name = t2.name

It does not work. Why..There are few matching records in table1 when physically compared with table2
