Help Optimising SQL Query
Jul 23, 2005Hi,I have a problem I would really appreciate help with. I am generatingdynamic SQL and need to optimise it. The specific example I am trying tooptimise looks like this:SELECT DISTINCT DataHeaderID FROM TB_DataDetailText T1 WHERE(EntityFieldID IN ( 31) AND (Data LIKE '12BORE%' )) AND(DataHeaderID=(SELECT DISTINCT DataHeaderID FROM TB_DataDetailText CT2WHERE T1.DataHeaderID = CT2.DataHeaderID AND (EntityFieldID IN ( 34)AND (Data LIKE 'SIDE BY SIDE%' )) ))AND(DataHeaderID=(SELECT DISTINCT DataHeaderID FROM TB_DataDetailText CCT3WHERE T1.DataHeaderID = CCT3.DataHeaderID AND (( Data LIKE 'church%' ))))I was OK optimising it with just 2 criteria and changed:SELECT DISTINCT DataHeaderID FROM TB_DataDetailText T1 WHERE(EntityFieldID IN ( 31) AND (Data LIKE '12BORE%' )) AND(DataHeaderID=(SELECT DISTINCT DataHeaderID FROM TB_DataDetailText CT2WHERE T1.DataHeaderID = CT2.DataHeaderID AND (( Data LIKE 'church%' ))))which took 26 seconds to using a derived tableSELECT distinct T1.DataHeaderID FROM TB_DataDetailText as T1inner join (SELECT distinct DataHeaderID, Data FROM TB_DataDetailText )CT2on T1.DataHeaderID = CT2.DataHeaderIDWHERE(T1.EntityFieldID IN ( 31) AND (T1.Data LIKE '12BORE%' ))and (( CT2.Data LIKE 'church%' )) which took 0.03 seconds on the same data.My problem is I need to write code to generate the SQL for 1 to n criteriaand am struggling to write the query for more than 2Best regards,Andrew

Optimising SQL Jobs
Apr 30, 2008Hi all,
I have 20 SQL jobs thst are scheduled to run from say every 5mins to others that run every hour.
Does anyone know the best way to optimise these jobs to run.
At the moment once these jobs are running I cannot browse any tables in teh DB. I get a locked timeout rquest exceeded..
Do I need to stagger when the jobs run.
Or make one big job where they all run one after another ?
Any help ?

Optimising Big Queries
Mar 26, 2008Hi there
Recently our company purchased a product from ip2location.com; a database containing 2.9million IP address ranges, and their approximate cities/countries of registration.
Naturally, I thought - "Hey, wouldn't it be great if we could cross reference this with our IIS logs so we could see where our visitors are from?".
So, I set about doing just that. Our IIS logs are already in SQL.
The trouble is, the ip2location database is so large that executing a query against it to find which range a particular IP address is within takes me 1 second. Multiply that by 1,000,000 log rows, and Houston - we have a problem.
One of the issues is that each record in the ip2location database comprises a FROM_IP and TO_IP range to describe a range of IPs. So to find which IP range a particular IP resides in, I have to join using a BETWEEN statement (or so, I think anyway!).
Does anyone have any suggestions on how to improve this process, or has anyone done anything similar before?
Ideally, I'd like to write a trigger to grab the IP region data (i.e. City/Country) and update the IISLog with that value when the new row is inserted, saving me having to do it later.
I tried this, and the batch import of IIS logs into SQL took so long I got bored and gave up :)
Any help anyone can offer would be appreciated.
Many thanks
Richard.
P.S. Somebody is bound to ask - "Why couldn't you just use Google Analytics?"; my answer is because we want to slice up our log data into chunks, and give it to our customers in semi-real time. Plus the logs report on other services - not just HTTP. ;)
Optimising Queries
Mar 23, 2006Hi.Maybe I'm just being dim, but I'm struggling to get my head aroundoptimising a query with regard to indexes. If I make a select query, suchas a pseudo-example 'select * from bigtable where foo='bar' and(barney>rubble and fred<flintoff)', and the table is indexed on 'foo', howcould I make that any better? What indexes could I add, or what could Ichange in the query?I know it looks simple, but so am I.CheersChris Weston
View 5 Replies View RelatedOptimising Select Statements Which Has A ‘LIKE’ Where Clause.
Dec 14, 2004Hi all
I have been doing some development work in a large VB6 application. I have updated the search capabilities of the application to allow the user to search on partial addresses as the existing search routine only allowed you to search on the whole line of the address.
Simple change to the stored procedure (this is just an example not the real stored proc):
From:
Select Top 3000 * from TL_ClientAddresses with(nolock) Where strPostCode = ‘W1 ABC’
To:
Select Top 3000 * from TL_ClientAddresses with(nolock) Where strPostCode LIKE ‘W1%’
Now this is when things went a bit crazy. I know the implications of using ‘with(nolock)’. But seeing the code is only using the ID field to get the required row, and the database is a live database with hundreds of users at any one time (some updating), I think a dirty read is ok in this routine, as I don’t want SQL to create a shared lock.
Anyway my problem is this. After the change, the search now created a Shared Lock which sometimes locks out some of the live users updating the system. The Select is also extremely SLOW. It took about 5 minutes to search just over a million records (locking the database during the search, and giving my manager good reason to shout abuse at me). So I checked the indexes. I had an index set on:
strAddressLine1, strAddressLine2, strAddressLine3, strAddressLine4, strPostCode.
So I created an index just for the strPostCode (non clustered).
This had no change to the ‘Like select’ what so ever. So I am now stuck.
1)Is there another way to search for part of a text field in SQL.
2)Does ‘Like’ comparison use the index in any way? If so how do I set this index up?
3)Can I stop a ‘Shared Lock’ being created when I do a ‘like select’?
4)Do you have any good comebacks I could tell the boss after his next outburst of abuse (please not so bad that he sacks me).
Any advice truly appreciated.
Optimising A Table With Lots Of Boolean Fields
Jul 17, 2006I have an application that reads a monitoring devices that produces 200 digital outputs every second and I would like to store them in a table. This table would get quite big fairly quickly as ultimately I would like to monitor over a hundred of these devices.
I would like to construct queries against each of the individual digital channels or combinations of them.
M first thought is to set up a table with 200 separate columns (plus others for date stamp, device ID etc) however, I am concerned that a table with 200 boolean (1-bit) fields would be an enormous waste of space if each field takes maybe one to four bytes on the hard disk to store a single bit. However, this would have the advantage of make the SQL queries more natural.
The other alternative is to create a single 200 bit field and use lots of ANDing and ORing to isolate bits to do my queries. This would make my SQL code less readable and may also cause nore hassle in the future if the inputs changed, but it would make the file size smaller.
In essence I am asking (hoping) the following : If I create a table with 200 boolean fields, does SQL server express automatically optimise the storage to make it more compact? This means that the server can mess around at the bit level and leave my higher level SQL code looking cleaner and more logical.
Optimising Merge Replication For Both Server And Client Subscribers
Jan 4, 2007
I need to merge replicate data to two different types of subscribers:
Clients subscribers which will have a very small percentage of the data from the central database. The data on these machines will be managed using dynamic filtering on host_name()
Server subscribers which will manage a copy of all the data from the central database
There will be far fewer server subscribers than client subscribers.
As I see it I have two options for the configuration
1) Use two separate merge publications €“ one which is filtered and one which isn€™t
2) Use a single merge publication and setup the filtering so that the server subscribers receive all the rows
Which option is likely to lead to better performance?
With option 1) there would be 2 complete sets of replication metadata which need to be maintained €“ so I am tending towards option 2. Are there any disadvantages in using a dynamic filter to return a very large number of rows?

Error: 8624 Internal Query Processor Error: The Query Processor Could Not Produce A Query Plan.
May 24, 2007SQL Server 2005 9.0.3161 on Win 2k3 R2
I receive the following error:
"Error: 8624, Severity: 16, State: 1 Internal Query Processor Error: The query processor could not produce a query plan. For more information, contact Customer Support Services."
I have traced this to an insert statement that executes as part of a stored procedure.
INSERT INTO ledger (journal__id, account__id,account_recv_info__id,amount)
VALUES (@journal_id, @acct_id, @acct_recv_id, @amount)
There is also an auto-increment column called id. There are FK contraints on all of the columns ending in "__id". I have found that if I remove the contraint on account__id the procedure will execute without error. None of the other constraints seem to make a difference. Of course I don't want to remove this key because it is important to the database integrity and should not be causing problems, but apparently it confuses the optimizer.
Also, the strange thing is that I can get the procedure to execute without error when I run it directly through management studio, but I receive the error when executing from .NET code or anything using ODBC (Access).

Opening Up Odbc Data Source In The Query Query Inside Of The Server Manager
Jun 15, 2007I'm trying to find the command to open up an odbc conection inside sql2005 express. I only have ues of an odbc connector, we're conection to remedy. We will eventually be using stored procedures to extract the data we need from remedy and doing additional data crunching. I'm a foxpro programmer so once I get the correct syntax for making the odbc connector I shold be ok. Also I need a really good advanced book on sql2005. The type of book that would have my odbc answer. I've spent all morning trying to find this information and was unable to.
Thanks in advance

This succeeds when the invalid column name is a valid column name in the outer query. So in this situation the sub-query would fail when run by itself but succeed with an incorrectly applied filter when run as a sub-query. The danger here is that if a SQL Server user runs DML in a production database with such a sub-query which then the results are likely not the expected results with potentially unintended actions applied against the data. how many SQL Server users have had incorrectly applied DML or incorrect query results and don't even know it....?
Why The Query Works In Query Analyser And Doesn't Work In Reporting Service ?
Apr 30, 2007
Hello everybody,
I'm developing a report using the following structure :
declare @sql as nvarchar(4000)
declare @where as nvarchar(2000)
set @sql = 'select ....'
If <conditional1>
begin
set @where = 'some where'
end
If <conditional2>
begin
set @where = 'some where'
end
set @sql = @sql + @where
exec(@sql)
I run it in query analyser and works fine, but when I try to run in Reporting Services, Visual studio stops responding and the cpu reaches 100 %.
I realize that when I cut off the if clauses, then it works at Reporting services.
Does anybody know what is happening?
Why the query works in query analyser and doesn't work in Reporting Service ?
Thanks,
MaurĂcio

Transact SQL :: Adding Results Of Query To Another Query Via Dynamically Added Columns
Jul 30, 2015For each customer, I want to add all of their telephone numbers to a different column. That is, multiple columns (depending on the number of telephone numbers) for each customer/row. How can I achieve that?
I want my output to be
CUSTOMER ID, FIRST NAME, LAST NAME, TEL1, TEL2, TEL3, ... etc
Each 'Tel' will relate to a one or more records in the PHONES table that is linked back to the customer.
I want to do it using SELECT. Is it possible?
Can A Calc'd Query Column Be Compared Against A Multi Value Variable Without A Nested Query?
Nov 15, 2007do i need to nest a query in RS if i want a calculated column to be compared against a multi value variable? It looks like coding WHERE calcd name in (@variable) violates SQL syntax. My select looked like
SELECT ... ,CASE enddate WHEN null then 1 else 0 END calcd name
FROM...
WHERE ... and calcd name in (@variable)
SQL Server Admin 2014 :: Estimated Query Plan For A Stored Procedure With Multiple Query Statements
Oct 30, 2015When viewing an estimated query plan for a stored procedure with multiple query statements, two things stand out to me and I wanted to get confirmation if I'm correct.
1. Under <ParameterList><ColumnReference... does the xml attribute "ParameterCompiledValue" represent the value used when the query plan was generated?
<ParameterList>
<ColumnReference Column="@Measure" ParameterCompiledValue="'all'" />
</ParameterList>
</QueryPlan>
</StmtSimple>
2. Does each query statement that makes up the execution plan for the stored procedure have it's own execution plan? And meaning the stored procedure is made up of multiple query plans that could have been generated at a different time to another part of that stored procedure?

I executed the code successfully and I got a box which asked for "Enter the query string".
I typed in the following: EXEC dbo.SalesByCategory @Seafood. I got the following box: Query attempt failed. Must declare the scalar variable "@Seafood". I am learning how to enter the string for the "SQL query programed in the subQuery_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnQuery.Click" (see the code statements listed above). Please help and tell me what I missed and what I should put into the query string to get the information of the "Seafood" category out.
Thanks in advance,

SP To Perform Query Based On Multiple Rows From Another Query's Result Set
Nov 7, 2007I have two tables .. in one (containing user data, lets call it u).The important fields are:u.userName, u.userID (uniqueidentifier) and u.workgroupID (uniqueidentifier)The second table (w) has fieldsw.delegateID (uniqueidentifier), w.workgroupID (uniqueidentifier) The SP takes the delegateID and I want to gather all the people from table u where any of the workgroupID's for that delegate match in w. one delegateID may be tied to multiple workgroupID's. I know I can create a temporary table (@wgs) and do a: INSERT INTO @wgs SELECT workgroupID from w WHERE delegateID = @delegateIDthat creates a result set with all the workgroupID's .. this may be one, none or multipleI then want to get all u.userName, u.userID FROM u WHERE u.workgroupIDThis query works on an individual workgroupID (using another temp table, @users to aggregate the results was my thought, so that's included) INSERT INTO @users SELECT u.userName,u.userID FROM tableU u LEFT JOIN tableW w ON w.workgroupID = u.workgroupID WHERE u.workgroupID = @workGroupIDI'm trying to avoid looping or using a CURSOR for the performance hit (had to kick the development server after one of the cursor attempts yesterday)Essentially what I'm after is: SELECT u.userName,u.userID
FROM tableU u
LEFT JOIN tableW w ON w.workgroupID = u.workgroupID
WHERE u.workgroupID = (SELECT workgroupID from w WHERE delegateID = @delegateID) ... but that syntax does not work and I haven't found another work around yet.TIA!
Easy SQL Question. How To Display Query Results In Query Analyzer
