Hi *.*
I've a problem with my query, perhaps you professionals can kindly
Help me to overcome this, let me explain the problem, We have an
Inventory software with about 8500 of Goods (we stored it in table
Called tblPart), every input/output of these Goods saves in a Table
Called tblInvRate, we have a field called Type, if it's input then
Type=1, if that's output the Type=-1, Qty is the number of input or
Output.
Now with the following query we get the remain of Goods in the
Inventory:
SELECT dbo.tblPart.pkCode, dbo.tblPart.Title,SUM(Rate.Qty *
Rate.Type) AS PriorRemain
FROM dbo.tblInvRate Rate INNER JOIN
dbo.tblPart ON Rate.fkPart = dbo.tblPart.pkCode
WHERE Rate.[Date] < '850515'
GROUP BY dbo.tblPart.pkCode, dbo.tblPart.Title
HAVING SUM(Rate.Qty * Rate.Type)>0
This query takes about 1 sec to execute,
In tblInvRate we have a field called IsRated and Rate, Rated and
IsRated sets in a sp named prRatingInv which calculate the rate of the
Goods and...
We need to have the last rate of Goods in the remain query so we use
This:
SELECT dbo.tblPart.pkCode, dbo.tblPart.Title,
SUM(Rate.Qty * Rate.Type) AS PriorRemain,
(SELECT TOP 1 Rate
FROM dbo.tblInvRate
WHERE (fkPart = dbo.tblPart.pkCode
AND [Date]<='850515' And IsRated = 1)
ORDER BY [Date] DESC, [Time] DESC) AS
Rate
FROM dbo.tblInvRate Rate INNER JOIN
dbo.tblPart ON Rate.fkPart = dbo.tblPart.pkCode
WHERE Rate.[Date] < '850515'
GROUP BY dbo.tblPart.pkCode, dbo.tblPart.Title
HAVING SUM(Rate.Qty * Rate.Type)>0
Above query may take about 40 to 80 secs to execute!!! (Total number of
rows in the tblInvRate is about 1.000.000 records)
H've run the Index Wizard but it can't find any more index on the
Tables, now would you please help me in this situation,
here is the schema of these tables:
CREATE TABLE [tblPart] (

Thanks in advance,
Waiting for your tips and advices,
HamedHamed,
Try using the correlated query after the remain of Goods in the Inventory
has been calculated.
select
a.*,
(
SELECT TOP 1
b.Rate
FROM
dbo.tblInvRate as b
WHERE
b.fkPart = a.pkCode
AND b.[Date] <= '850515'
And b.IsRated = 1
) as Rate
from
(
SELECT
dbo.tblPart.pkCode,
dbo.tblPart.Title,
SUM(Rate.Qty * Rate.Type) AS PriorRemain
FROM
dbo.tblInvRate as Rate
INNER JOIN
dbo.tblPart
ON Rate.fkPart = dbo.tblPart.pkCode
WHERE
Rate.[Date] < '850515'
GROUP BY
dbo.tblPart.pkCode, dbo.tblPart.Title
HAVING
SUM(Rate.Qty * Rate.Type)>0
) as a
go

Please, can you post indexes for each table also?
Seems that column [dbo].[tblInvRate].[IsRated] is not integer, correct?.
Ttry casting the value you compare with. Let us assume it is bit data type,
then:
|--Filter(WHERE:(Convert([b].[IsRated])=1))
(
SELECT TOP 1
Rate
FROM
dbo.tblInvRate
WHERE
fkPart = dbo.tblPart.pkCode
AND [Date]<='850515'
And IsRated = cast(1 as bit) <-- change this

In my first post I forgot the "order by" clause in the correlated subquery.
I think that is the reason why we are getting diffrent execution plans.
select
a.*,
(
SELECT TOP 1
b.Rate
FROM
dbo.tblInvRate as b
WHERE
b.fkPart = a.pkCode
AND b.[Date] <= '850515'
And b.IsRated = 1
ORDER BY [Date] DESC, [Time] DESC <-- forgot this
) as Rate
from
(
SELECT
dbo.tblPart.pkCode,
dbo.tblPart.Title,
SUM(Rate.Qty * Rate.Type) AS PriorRemain
FROM
dbo.tblInvRate as Rate
INNER JOIN
dbo.tblPart
ON Rate.fkPart = dbo.tblPart.pkCode
WHERE
Rate.[Date] < '850515'
GROUP BY
dbo.tblPart.pkCode, dbo.tblPart.Title
HAVING
SUM(Rate.Qty * Rate.Type)>0
) as a
go
