Hi,
I'm a novice to the query world.
I'm trying to make a select query where I have to select 'rate' from table 'A' if the rate has not been changed in table 'B'. The table 'B' has code of table 'A' as foreign key.
Someone please help me to make this query.

Hoping for quick response. Thanking you in anticipation.

[code]
select a.rate
from tableA a
where exists
(
select *
from tableB b
where b.code = a.code
and b.rate = a.rate
)

OR

select a.code, a.rate
from tableA a
inner join tableB b on a.code = b.code
where a.rate = b.rate
[/code]
