Hi Everybody,
One of my friend asked me "How do we reduce the query logical, scan reads
in SQL Server?".
I really don't know, how to answer him.
Can anybody explain me regarding this.
thanks,
Srini
How do I determine which method I should use ifI want to optimize the performance of a database.I took Northwind's database to run my example.My query is I want to retrieve the Employees' Firstand Last Names that sold between $100,000 and$200,000.First let me create a function that takes the EmployeeIDas the input parameter and returns the Employee'sFirst and Last name:CREATE FUNCTION dbo.GetEmployeeName(@EmployeeID INT)RETURNS VARCHAR(100)ASBEGINDECLARE @NAME VARCHAR(100)SELECT @NAME = FirstName + ' ' + LastNameFROM EmployeesWHERE EmployeeID = @EmployeeIDRETURN ISNULL(@NAME, '')ENDMy first method to run this:SELECT EmployeeID, dbo.GetEmployeeName(EmployeeID) ASEmployee, SUM(UnitPrice * Quantity) AS AmountFROM OrdersJOIN [Order Details] ON Orders.OrderID =[Order Details].OrderIDGROUP BY EmployeeID,dbo.GetEmployeeName(EmployeeID)HAVING SUM(UnitPrice * Quantity) BETWEEN100000 AND 200000It's running in 4 seconds time. And here are theStatistics IO and Time results:SQL Server Execution Times:CPU time = 0 ms, elapsed time = 0 ms.SQL Server Execution Times:CPU time = 0 ms, elapsed time = 0 ms.SQL Server Execution Times:CPU time = 0 ms, elapsed time = 0 ms.SQL Server parse and compile time:CPU time = 17 ms, elapsed time = 17 ms.(3 row(s) affected)Table 'Order Details'. Scan count 1, logical reads 10,physical reads 0, read-ahead reads 0.Table 'Orders'.

And here are the Statistics IOand Time results:SQL Server Execution Times:CPU time = 0 ms, elapsed time = 0 ms.SQL Server Execution Times:CPU time = 0 ms, elapsed time = 0 ms.SQL Server Execution Times:CPU time = 0 ms, elapsed time = 0 ms.SQL Server parse and compile time:CPU time = 0 ms, elapsed time = 0 ms.SQL Server Execution Times:CPU time = 0 ms, elapsed time = 0 ms.SQL Server Execution Times:CPU time = 0 ms, elapsed time = 0 ms.SQL Server Execution Times:CPU time = 0 ms, elapsed time = 0 ms.SQL Server parse and compile time:CPU time = 0 ms, elapsed time = 0 ms.Table '#temp_Orders0000000000F1'.

The logical reads arevery few compared to the second method.The second code is less clean and uses a temp table buttakes 0 second to execute. The logical reads are waytoo high compared to the first method.What am I supposed to conclude in this example?Which method should I use over the other and why?Are both methods good depending on which I prefer?If I can wait four seconds, it's better to reduce the logicalreads in order to provide less Blocking on the live tablesin a heavily accessed database?Which method should I choose on my own database?Calling a function like dbo.GetEmployeeName getsprocessed per each returned row, correct? That meansIf i had a scenario where 1000 records were to be returnedwould it be better to dump 1000 records to a temp tablevariable and then call a function to process each recordone at a time?Or would the direct approach without usinga temp table cause slower processing and moreblocking/deadlocks because I am calling the functionper each row as I am accessing directly from the tables?Thank you
View 1 Replies View Relatedwe had some slow down complaints lately and this query seems to be the culprit almost every single time. The estimated execution plan is a clustered index seek as there is a clustered index on the uidcustomerid column. setting profile statistics on shows that every time it executes it does an index seek.
profiler session showed a huge number of reads for these queries depending on the value being looked up. 1500 through 50000. i set up profile io on and the culprit is lob logical reads. everything else is 0 or very low. in this case lob logical reads is over 1700.
3 of the columns in the select statement are text columns. when i take them out of the query the lob logical reads drops to 0 and goes up incrementally as i add each column back in.
is there anyway to improve the performance without changing data types to varchar(max)?

i am assuming there is a better way to write this query (since im not too proficient in SQL)
sql Code:
Original
- sql Code
select client_id from clients where client_id not in
(select schedule_det.client_id from schedule_det,
schedule_mstr where schedule_det.schedule_id=schedule_mstr.schedule_id
and schedule_mstr.status_code!='COMPLETE')
SELECT client_id FROM clients WHERE client_id NOT IN (SELECT schedule_det.client_id FROM schedule_det, schedule_mstr WHERE schedule_det.schedule_id=schedule_mstr.schedule_id AND schedule_mstr.status_code!='COMPLETE')
ok i have table1, table 2 and table 3.
these table have some common feild names. table1,2 and 3 all have a,b,c and d as field names. each table has other field names too but the ones they all have in common are a,b,c and d.
so i would like to write a query that returns all rows from all 3 tables where column d is greater than 5 and less than 10.
so basically i want it to treat the records from all 3 tables ad one big dataset.
how would i write a query to do this.
i know i could say:
SELECT a,b,c,d
FROM table1,table2,table3
but what gets me is the WHERE clause
do i have to say WHERE table1.d >5 AND table1.d <10 OR table2.d>5 AND table2.d <10 OR table3.d>5 AND table3.d <10
??
any guidance please?

I have a table with many records in it. There is one field called "Nature". How would I select the value that appears the most often in the "Nature" field? The nature field contains text.
For example, this code selects those with more than 10 records...
I just want the top record.
SELECT count(*) FROM WEBASGN_FULL GROUP BY NATURE HAVING count(*) > 10
Basically select nature from webasgn_full that occurs the most often in the table....
Thanks
I need help on writing a query which will return my results as I need them.
I have three tbls.
TimeType, TimePlan and TimeSpent
TimeType simply lists the Individual Jobs (types) a user can be doing.
The TimePlan and Time Spent each list individual records with start and end dates and what TimeType was being performed.
Each TimeType can have multiple starting and ending dates for the TimePlan and Timespent.
I need my results to show individual timetypes, with the starting and end dates for the Timeplans and also the TimeSpent
EG:
TypeType | TimeplanStart | TimeplanEnd | TimeSpentStart | TimeSpentEnd
Writing | 01/02/2007 | 02/02/2007 | |
Writing | | 03/02/2007 |
So there will be multiple Types, and for each one I need to show the start and end dates.
I would normally write this as three seperate queries.
The first would get the TimeTypes,
The second the TimePlan starting and ending dates for that type,
The third , the Spent starting and ending dates for that type
However that doesn't come across as very efficient so I wonder if there was any other alternative
Please help me to get this result

Hi !
There is one table tCustomers. It has following columns: ID, Name, Code...
By the mistake in this table has appeared incorrect records (duplicates).
How can I write the query to find them ?
I tried:
Select c.ID ID1,s.ID ID2, c.NAME NAME1,s.NAME NAME2, c.Code C1, s.Code C2, From tCustomers c, tCustomers s
where c.Code=s.Code and c.ID <> s.ID
But the result is not that I expected
I have a Table "T1" with col "id","name".
Table "T2" with "TID","ID" etc..d
[Here, id of T1 is mapped to id of T2]
Now, I wanted to write a query such that the query should output T1.id,T1.name and a third column which will show me the count of records in T2 corresponding to an ID in T1.
Any help on this is highly appreciated.
Thanks!
hi guys,
I run into this question again. Here is it.
I have two tables like this:
StoreVisit(StoreVisitID(PK), UserID, StoreID, LoginID, LogoutID)
ProductOrders(ProductID, UserID, StoreID, OrderQuantity, StoreVisitID)
What I want to do is, I need to find out the lastest store visit record and put the StoreVisitID into ProductOrders table for the same userID, StoreID. So what I tried is:
update ProductOrders set StoreVisitID=sv.StoreVisitID
from ProductOrders po
inner join (select top 1 * from StoreVisit where UserID=po.UserID and StoreID=po.StoreID order by StoreVisitID desc) sv
on po.StoreID=sv.StoreID and po.UserID=sv.UserID
Where po.UserID=@UID and po.StoreVisitID is null
When I run it, it shows the error:
The column prefix po, does not match with a table name or alias name used in the query.
Looks like it does not recognize the po in select top 1... .
I hope you guys already understand what I am trying to do. I am wondering what is the best way to do this?
Thanks.

i am working on asp.net
i am passing two values through querystring to the next page, that values are comming to next page but i want to display results on these two crieria hats.
i have written following query which working fine in sql server 2000

but when i am trying to do this in asp.net its not working. following code accepting only one value . i want to compair two value. Please guide me how to write above query in asp.net using 'and' and 'like' operatorasp.net ==>select * from addahall where HCity='" + city + "' ==> city is variable
please let me know as early as possible i have very less time.
I'll start by giving the basic idea of the data structure I'm looking at in the database (pardon my MS Paint skills!):
And this all starts with a root plan. So (taking projects out of the picture for the minute), it could be a structure going any number of levels down like so: plan -> goal -> strategy -> plan -> goal -> strategy -> plan -> goal -> strategy, etc.And not forgetting, that a strategy can also have any number of projects, and all these relationships are one to many, so it ends up being like a large tree structure.
What I am trying to accomplish is user security related, in that I need to enforce rules set to say whether a single user is allowed to view a project. You can define the rules at any level in the structure above. So if for instance, a user is given a rule that they can access anything from a goal, they can see any projects that exist in any strategies underneath that goal in the tree structure. I hope this is making sense so far... The rules can also just be defined at a specific project level.
These rules (at the moment, I'm more than happy to change if this is a silly way of doing it) are set in a table that has the columns:user_id intplan_id intgoal_id intstrategy_id intproject_id intallow bitEvery row will have a user_id value, and one of either a plan_id, goal_id, strategy_id or project id (which I thought would be a simple way to pull out what kind of rule if needed), and the allow column just defines if it's an allow or deny rule (a specific deny rule on any object lower in the tree structure will override any cascaded allow rule).
The way my application needs to grab this information, is to simply have some way of returning a list project_id values for which the current user is allowed to access. I'm basically stumped. The closest I have gotten (which still didn't quite work) was going to end up using quite a large number of cursors... Which is bad. It can be inefficient to an extent, as once these values are gathered once, I can store them in a Session variable, so it's not grabbing them every time the user tries to load a project.
Thanks for any help!

I can't figure out how to replace a single digit entry in my database with a new digit. i want to replace in the alarms.severity all values of 4 with a new value of 2. For some reason the script I wirte won't get past the digit 4 in the statement. Anyone have a script they can let me try?

i want to write a query to get 1st, 2nd and 3rd max salary ?
I am wondering if there is some type of recursive query to return the values I want from the following database.
Here is the setup:
The client builds reptile cages.
Each cage consists of aluminum framing, connectors to connect the aluminum frame, and panels to enclose the cages. In the example below, we are not leaving panels out to simplify things. We are also not concerned with the dimensions of the cage.
The PRODUCT table contains all parts in inventory. A finished cage is also considered a PRODUCT. The PRODUCT table is recursively joined to itself through the ASSEMBLY table.
PRODUCTS that consist of a number of PRODUCTS are called an ASSEMBLY. The ASSEMBLY table tracks what PRODUCTS are required for the ASSEMBLY.
Sample database can be downloaded from http://www.handlerassociates.com/cage_configurator.mdb
Here is a quick schema:
Table: PRODUCT
--------------------------
PRODUCTIDPK
PRODUCTNAMEnVarChar(30)
Table: ASSEMBLY
--------------------------
PRODUCTIDPK(FK to PRODUCT.PRODUCTID)
COMPONENTIDPK(FK to PRODUCT.PRODUCTID)
QTYINT
I can write a query that takes the PRODUCTID, and returns all
PRODUCT

PRODUCTIDPRODUCTNAME
--------------------
1Cage Assembly - Solid Sides
2Cage Assembly - Split Back
3Cage Assembly - Split Sides
4Cage Assembly - Split Top/Bottom
5Cage Assembly - Split Back and Sides
6Cage Assembly - Split Back and Top/Bottom
7Cage Assembly - Split Back and Sides and Top/Bottom
833S - Aluminum Divider
933C - Aluminum Frame
10T3C - Door Frame
11Connector Kit
12Connector Socket
13Connector Screws

I need a query that will give me all parts for each PRODUCT.
Example: I want all parts for the PRODUCT "Cage Assembly - Split Back"
The results would be:
PRODUCTIDPRODUCTNAME
--------------------
2Cage Assembly - Split Back
1Cage Assemble - Solid Back
933C - Aluminum Frame
10T3C - Door Frame
11Connector Kit
833S - Aluminum Divider
12Connector Socket
13Connector Screws
Is it possible to write such a query or stored procedure?
