hi
create table cust_product
(cust varchar(10), prod varchar(10))
insert into cust_product VALUES ('A','P')
insert into cust_product VALUES ('A','Q')
insert into cust_product VALUES ('A','P')
insert into cust_product VALUES ('B','Q')
insert into cust_product VALUES ('C','Q')
insert into cust_product VALUES ('A','P')
insert into cust_product VALUES ('B','P')
insert into cust_product VALUES ('C','P')
I need the output to be
cust No. of Product (P) No. of Product(Q)
A 3 1
B 1 1
C 1 1
Can anyone help?

select cust,

count(case when prod='P' then prod end) as 'No. of Product (P)',

count(case when prod='Q' then prod end) as 'No. of Product (Q)'

from cust_product

group by cust

order by cust

or

select cust, sum(case prod when 'P' then 1 else 0 end) as 'No. of Product (P)' , sum(case prod when 'Q' then 1 else 0 end) as 'No. of Product (Q)'

from cust_product

group by cust

order by cust

Since you are using SQL Server 2005 you can use a PIVOT.

declare @cust_product table

(cust varchar(10), prod varchar(10))

insert into @cust_product VALUES ('A','P')

insert into @cust_product VALUES ('A','Q')

insert into @cust_product VALUES ('A','P')

insert into @cust_product VALUES ('B','Q')

insert into @cust_product VALUES ('C','Q')

insert into @cust_product VALUES ('A','P')

insert into @cust_product VALUES ('B','P')

insert into @cust_product VALUES ('C','P')

SELECT cust, [P],

FROM @cust_product

PIVOT(COUNT(prod) FOR prod IN ([P],

)) AS ProductPivot

How about using PIVOT?:

DECLARE @cust_product TABLE (cust varchar(10), prod varchar(10))

insert into @cust_product VALUES ('A','P')

insert into @cust_product VALUES ('A','Q')

insert into @cust_product VALUES ('A','P')

insert into @cust_product VALUES ('B','Q')

insert into @cust_product VALUES ('C','Q')

insert into @cust_product VALUES ('A','P')

insert into @cust_product VALUES ('B','P')

insert into @cust_product VALUES ('C','P')

SELECT cust, P AS COUNT_OF_P, Q AS COUNT_OF_Q

FROM @cust_product

PIVOT (COUNT(prod) FOR prod IN ([P],

)) AS UNPVT

Enjoy!
