Sum(Case when c= '3' then 1 else 0 end) as c,


where  msg not like '%fatal%' or msg not like '%exception%' or msg not like   '%fopen%'
then Select telco ,
Sum(Case when a= '1' then 1 else 0 end) as a_e, 
Sum(Case when b= '2' then 1 else 0 end) as b_e, 
Sum(Case when c= '3' then 1 else 0 end) as c_e,

From temp_inbox  group by t

here a, b ,c column name

I want to write the above requirement one query. If i write two query based two where condition then i get result but i want to write single query and show my result in the following way :

a   b   c   a_e   b_e   c_e

5   6   7    10    4     10
1   2   7     45   20    2

sample data:

         a  b   c  msg

         1  0   0  fatalerror

         0  0   3   successed
         1  0   0   exception
         0  2   0   successful

select telco, 
sum(
     case when (msg  like '%fatal%' or out_msg like '%exception%' or out_msg like '%fopen%') and a = '1' 
     then 1 else 0 end 
) as a,
sum(
     case when (msg  like '%fatal%' or out_msg like '%exception%' or out_msg like '%fopen%') and a = '2' 
     then 1 else 0 end 
) as b,
sum(
     case when (msg  like '%fatal%' or out_msg like '%exception%' or out_msg like '%fopen%') and a = '3' 
     then 1 else 0 end 
) as c,
 sum(
     case when (msg not like '%fatal%' or out_msg not like '%exception%' or out_msg not like '%fopen%') and a = '1' 
     then 1 else 0 end 
) as a_e,
sum(
     case when (msg not like '%fatal%' or out_msg not like '%exception%' or out_msg not like '%fopen%') and a = '2' 
     then 1 else 0 end 
) as b_e,
sum(
     case when (msg not like '%fatal%' or out_msg not like '%exception%' or out_msg not like '%fopen%') and a = '3' 
     then 1 else 0 end 
) as c_e
