Getting 2 SUMs from the same table

Hi All

I'm really stuck on this one so would appreciate any help you can give.

In essence, I have 1 SQL 2000 table with rows of data logging stock
movement. To differenciate between a stock sale and a stock receipt the
table has a TRANSACTIONTYPE field so that 8,7 equal invoices and 3 equals a
receipt.

I've been asked to report on this data by suming the total qty used on
invoices and the total qty recvd for each stock item, but I can't figure out
how I sum the same rows twice in the one query.

For example, my query is as follows:

select st.stockid as 'STYLE',
s.picture as 'COLOUR',
'' as 'IN FIRST IN LAST WEEK',
'' as 'THIS WEEK IN',
'' as 'TOTAL IN',
'' as 'OUT FIRST OUT LAST WEEK',
SUM(st.quantity) as 'THIS WEEK OUT',
'' as 'TOTAL OUT',
'' as 'REMAINING',
'' as 'TOTAL DIGESTION %'
from stocktransactions st, stock s
where st.stockid = s.stockid and
st.transactiontype in (8,7) and
st.transactiondate >= '2005-07-12 00:00:00' and
st.transactiondate <= '2005-07-12 23:59:59'
group by st.stockid,s.picture
order by st.stockid

Apart from the 'THIS WEEK OUT' column SUMing all of the stock sales by
transactiontype 7,8, I also want the 'THIS WEEK IN' column to SUM all of the
transactions by transactiontype 3, so that I get the following results:

STYLE COLOUR ... THIS WEEK IN ... THIS WEEK OUT ......
IVP Red 12 23
STP Blue 4 15
etc etc

My problem is that I don't want to exclude a stock item if it hasn't got a
row/value for the THIS WEEK IN and/or the THIS WEEK OUT. Am I asking too
much of SQL?

My table schemas are as follows:

create table STOCKTRANSACTIONS
(
STOCKTRANSACTIONID T_STOCKTRANSACTIONSDOMAIN not null
identity(1,1),
TRANSACTIONTYPE smallint not null,
TRANSACTIONDATE datetime null ,
REFERENCE varchar(40) null ,

Madhivanan|||Robbie,

You have some data types in your schema that aren't really data types.
You have STOCKTRANSACTIONID as a data type of
T_STOCKTRANSACTIONSDOMAIN. Are you using SQL Server? How about
posting with good data types and some inserts so people can help you
better.

Thanks,

I assume that these are so-called user-defined data types created with
sp_addtype.
