"Timeout expired" error, when executing view in SQL Server 2008 - sql

Question

I've written a query in SQL Server 2008. The query takes about 4 minutes to execute.
I need this query as a View. So, I've created a view with this query and when I try to execute the view creation script, it shows the following error:
Timeout Expired.
The timeout period elapsed prior to completion of the operation or the server is not responding.
The query is:
SELECT t.jrnno,
(SELECT SUM(t1.amount)
FROM dbo.T_sh AS t1
WHERE (t1.b_or_s = '1') AND (t1.jrnno = t.jrnno)) AS buy,
(SELECT SUM(t2.amount)
FROM dbo.T_sh AS t2
WHERE (t2.b_or_s = '2') AND (t2.jrnno = t.jrnno)) AS sale,
SUM(t.amount) AS Total,
SUM(t.h_crg) AS Howla,
SUM(t.l_crg) AS Laga,
SUM(t.taxamt) AS Tax,
SUM(t.commsn) AS Commission
FROM dbo.T_sh AS t
WHERE (t.tran_type = 'S')
AND (t.jrnno NOT IN (SELECT DISTINCT jrnno
FROM dbo.T_ledger))
GROUP BY t.jrnno
T_sh and T_ledger both tables have about 100K rows. What could be the possible reason and how can I overcome this?
Update:
select
t.jrnno,
SUM(CASE WHEN t.b_or_s = 1 THEN t.amount ELSE NULL END) buy,
SUM(CASE WHEN t.b_or_s = 2 THEN t.amount ELSE NULL END) sale,
SUM(t.amount) AS Total,
SUM(t.h_crg) AS Howla,
SUM(t.l_crg) AS Laga,
SUM(t.taxamt) AS Tax,
SUM(t.commsn) AS Commission
FROM
dbo.t_sh t
WHERE
t.tran_type = 'S'
AND NOT EXISTS(SELECT 1 FROM dbo.T_ledger x where x.jrnno = t.jrnno)
group by
t.jrnno
It solved my problem. Thanks everyone for your quick response.

Answer 1

Try this query:
select
t.jrno,
SUM(CASE WHEN t1.b_or_s = 1 THEN t.amount ELSE NULL END) buy,
SUM(CASE WHEN t1.b_or_s = 2 THEN t.amount ELSE NULL END) sale,
SUM(t.amount) AS Total,
SUM(t.h_crg) AS Howla,
SUM(t.l_crg) AS Laga,
SUM(t.taxamt) AS Tax,
SUM(t.commsn) AS Commission
FROM dbo.t_sh t
WHERE t.tran_type = 'S'
AND NOT EXISTS(SELECT 1 FROM dbo.T_ledger x x.jrno = t.jrno)

Answer 2

Your query only needs to scan dbo.T_sh once:
SELECT t.jrnno,
SUM(CASE WHEN t.b_or_s = 1 THEN t.amount ELSE NULL END) AS buy,
SUM(CASE WHEN t.b_or_s = 2 THEN t.amount ELSE NULL END) AS sale,
SUM(t.amount) AS Total,
SUM(t.h_crg) AS Howla,
SUM(t.l_crg) AS Laga,
SUM(t.taxamt) AS Tax,
SUM(t.commsn) AS Commission
FROM dbo.T_sh AS t
WHERE t.tran_type = 'S'
AND t.jrnno NOT IN (SELECT DISTINCT
tl.jrnno
FROM dbo.T_ledger tl)
GROUP BY t.jrnno
