How can I replace column value with a particular value in SQL

Question

Hi All,
Can anyone please tell me how can I format my output with replacing a column value with a specific value which actually depends on the present value of the column
I am executing the following SQL statement
select state,count(id) from <table_name> where composite_dn= <composite_dn_name> group by state;
My Present output is:
State No.Of Instance
1 3
3 28
I want to replace the value in the column state as follows
State No.OfInstances
Completed 3
Faulted 28
I want "1" to be reppaced by "Completed" and "3" to be replaced by "Faulted"
Is is possible with SQL or PL/SQL , if it is then how can I achieve this required result. Please help!!
Thanks in Advance!!

Hi Roshni,
I guess this CASE clause can be simulated by a DECODE and also it is very easy to use.
Refer -- http://www.techonthenet.com/oracle/functions/decode.php
select decode(t1.state,t2.state_id,t2.state_name), t1.count_id
from <table_2> t2, (select state,count(id) count_id
from <table_name>
where composite_dn= <composite_dn_name>
group by state) t1
where t1.state = t2.state_id;HTH
