Slow Query With Java Using Prepare Statement
Jul 12, 2007
We are using sql server 2005 with java and the last version of driver JDBC, some querys show bad performance when you send by application but if you use sql query analyzer the performance is excellent. We have take a profiler trace and saw that Java call SP_PREPEXEC when it makes a call of preparestatement. We taken the sentence from profiler (with SP_PREPEXEC) and saw the same problem, the query plan is bad, but if we avoid use the prepare statement the query works fine and the performance problem is overcome. Since we have the application with java and use every time the preparedstatement sentence from java, it is very expensive for us , change the code. Do you have any solution for these problem?

I am trying to use the export wizard to export to a MS Access file, using the provide source query option. I get the error below when pasting the query in. The query does run successfully in SSMS, it is a long running query. About 8 minutes to complete.
TITLE: SQL Server Import and Export Wizard

The statement could not be parsed.

ADDITIONAL INFORMATION:
Deferred prepare could not be completed.
Query timeout expired (Microsoft SQL Native Client)
Any ideas?

Hi,
I've got a table with about 500 000 records and growing monthly by about 40 000 records
When I perform the following query:
DELETE from [myTable] WHERE Month = '07' AND Year='2005'
This query will take about 10 minutes to execute. Columns Month & Year are both indexed.
Surely MSSQL can't be this slow on only 500 000 records.
Must I do some other database optimization ???
Thanks

hello,I have the following query. it returns result in less than 1 second.select *from employee e, address awhere e.id=a.emp_idand e.id=1234The problem is that it becomes extremely slow if i take the last lineout. So the query looks like:select *from employee e, address awhere e.id=a.emp_idThe above query is only supposed to return ~500 rows. but i stillhaven't got the result back after 30 minutes.Does anyone have any suggestions about troubleshooting this problem?Thank you in advance!Eddy

I have been trying to optimize a few DAX calculations that I have in my cube and ran into this problem Basically my DAX Measure
Counterparty Collateral Base DKK:=
[Counterparty Collateral Contracts DKK (filtered)]
+
CALCULATE(-[Account Balances DKK], Accounts[Counterpart Type ID] <> 8, Accounts[ContractTypeID] <> 14, Accounts[ContractTypeID] <> 16)
is pretty fast,
whereas as soon as I change the 2nd part to only add Account Balance if its>0, it takes ages i.e.
Counterparty Collateral Base DKK:=
[Counterparty Collateral Contracts DKK (filtered)]
+
IF(CALCULATE(-[Account Balances DKK], Accounts[Counterpart Type ID] <> 8, Accounts[ContractTypeID] <> 14, Accounts[ContractTypeID] <> 16)>0,
CALCULATE(-[Account Balances DKK], Accounts[Counterpart Type ID] <> 8, Accounts[ContractTypeID] <> 14, Accounts[ContractTypeID] <> 16),0)
Offcourse because I check every row I suppose with that "if" statement. Question is how do I improve it?
B
y the Way: [Account Balances DKK] is in the table - Account Balances
[Counterparty Collateral Contracts DKK (filtered)] is in the table- Open Positions
This calculated measure [Counterparty Collateral Base DKK] is in Open Positions.And the query in MDX, that I run to pull this measure, looks like
select {[Measures].[Counterparty Collateral Base DKK]
}on 0,
Non Empty {[Accounts].[Counterpart ID].children
*[Base Currencies].[Currency Code].children
*[Products].[Product Name].children
} on 1
from [model]
where [Dates].[Date].&[2015-06-30T00:00:00]
The requirement is such that I have to add the measures in two separate tables.How can I improve the performance when adding the filter?

The following stored procedure is run whenever someone searches my database. When I first created the site, this search took less than 3 seconds. Now, there is more data in the system and the search is taking over 30 seconds.
I am not very good with SQL and I'm sure I am doing some dumb things. Is there a better way to write this query to speed things up?

Hi, I have a query which returns normally in less than a couple of seconds. When coupled with a "TOP" statement however, the execution time changes in a way I can't explain.
When using "TOP 1000", the query returns in its normal time. Any top value greater than 10 seems to function normally. However, as soon as we hit this "magic number" the query begins taking 30+ seconds to return.
As far as we can see, there is nothing odd about this query or the data that it is searching, and this problem has us stumped! Can anyone explain why top is producing these results, and is there any optomisation changes that anyone can suggest to give us faster queries in these cases?
Many thanks, Andy J.

I support a website (ASP.NET 2.0) where recently users have been unable to insert data due to timeout issues. The functionality executes a query that inserts a single row into a SQL Server 2005 db table. I tried running this query from the backend, and it took 4:48 to insert a single row! Interestingly, after that initial agony any similar inserts I tried took no time whatsoever. I have checked the execution plan, but unfortunately don't really know what I'm looking for with inserts, as most of my experience with execution plans is with select statements. Any resources anyone could point me to for troubleshooting this would be much appreciated.
Thanks,
-Dave

I have 2 SQL servers. And in the first one I have added the second SQL as a Link Server. When I run an SQL statement on the linked server I get the following message.
Server: Msg 7202, Level 11, State 1, Line 1Could not find server 'PROD' in sysservers. Execute sp_addlinkedserver to add the server to sysservers.[OLE/DB provider returned message: Deferred prepare could not be completed.]
The SQL statement that I am runnins is
Select * from openquery(PROD,'Select * from PROD.GMS.dbo.qryDispCL')
But when I run only the SQL statement "Select * from PROD.GMS.dbo.qryDispCL" it works perfect. But I need to have the first statement running.
Please help. Your valuable feedback is greatly appriciated.

Hello,
I am trying to use the Import export wizard to created a package,
using the provide source query option. If i just copy the query from a text file
and try to paste , sql only accepts it partially. so i saved it as a sql file
and then opened it in the window. However, when i click on 'next' or 'parse' , i
get the below error.
TITLE: SQL Server Import and Export Wizard
------------------------------
The statement could not be parsed.
------------------------------
ADDITIONAL INFORMATION:
Deferred
prepare could not be completed.
Query timeout expired (Microsoft SQL Native Client)
The query is pretty big, but it executes successfully in the Management Studion Query Explorer window. I had no problem creating a package using DTS with the same query in Sql 2000. I also tried to migrate the package already existing in Sql 2000, but even though i can migrate it successfully , the package does not execute in Sql 2005. Also i tried other queries which are as big as this one, again the query source window during import/export does not seem to accept large queries??? I depend heavily on large queries for my packages, which i run daily. I have not had any issues with this is sql 2000. Can someone help me with this???
Thanks in advance.

I have an update query running which to just now has been running for 22 hours running on two tables 1 a lookuptable that has just been created within the batch the other a denormalised table for doing data analysis on
the query thats causing teh problem is
--//////////////////////////////////// this is the one thats running
Print 'Update Provider 04-05 EmAdmsCount12mths : ' + CAST(GETDATE() AS varchar)
GO
Update Provider_APC_2004_05
set EmAdmsCount12mths =
(Select COUNT(*)-1
from Combined_Admissions
where ((Combined_Admissions.NHSNumber = Provider_APC_2004_05.NHSNumber) or
(Combined_Admissions.PASNUMBER = Provider_APC_2004_05.PDDISTNO)) and
(Combined_Admissions.AdmDate BETWEEN DateAdd(yyyy,-1,Provider_APC_2004_05.AdmDate) AND Provider_APC_2004_05.AdmDate) AND
Combined_Admissions.AdmMethod like 'Emergency%')-- and
-- CA.NHSorPrivate = 'NHS'))
FROM Provider_APC_2004_05, Combined_Admissions
any help in improving speed would be most welcome as there are 3 more of these updates to run right after this one and the analysis tables are almost double the size of this one

DECLARE @BuildClrVersionx nvarchar(128)
SET @BuildClrVersionx =

I am getting the following errors:
OLE DB provider "SQLNCLI" for linked server "LKMSSQLADM01" returned message "Deferred prepare could not be completed.".
Msg 8180, Level 16, State 1, Line 1

If you have any ideas how I can run this query across a linked server I would appreciate it.

Hi,
I am using SQL Server Destinations in my data flow tasks. I'm running this package in the server until i encountered this error:

The error is specific to the component, but the error is fatal and will cause the Data Flow task to stop running. There may be error messages posted before this with more information about the failure.
What could be the reason for this? I don't usually have an error.

Having searched the forum, this one clearly has form... However beyond assisting those who have fallen at the first hurdle (i.e. forgetting/not knowing that they cannot execute the package remotely to the instance of SQL Server into which they are inserting), the issues raised by others have not been addressed. Thus I am bringing nothing new to the table here - just providing an executive summary of problems which others have run into, written about, but not received answers for.
First the complete error:
Description: Unable to prepare the SSIS bulk insert for data insertion. End Error Error: 2008-01-15 04:55:27.58 Code: 0xC004701A Source: <xxx> DTS.Pipeline Description: component "<xxx> failed the pre-execute phase and returned error code 0xC0202071. End Error DTExec: The package execution returned DTSER_FAILURE (1). Started: 4:53:34 AM Finished: 5:00:00 AM Elapsed: 385.384 seconds. The package execution failed. The step failed.
Important points
It mostly works - It produces no error more than 9 times out of 10.
It fails on random dataflows - My package has several dataflows, (mostly) executing concurrently. Where the error occurs it does not do so on the same dataflow each time: on one run it'll fail on dataflow A whilst B,C,D and E succeed, then A-E will all succeed (and continue doing so for the next ten runs thereafter), and then the error recurs for dataflow D, with A,B,C and E all succeeding.
Hope someone has something interesting to say,
Tamim.

This sounds like a pretty easy one. I have a SQL 2000 database with 2-3.4GHZ CPUs and 1GB of RAM. I have one database on it. I go in Query Analyzer on another machine and run a simple query like 'SELECT * FROM USERS' which should return 15,000 rows.
IT takes 30 (thirty) seconds to finish this query. OMG
Where do I start to decipher why on Earth this takes more than .01 seconds?
Thanks.

Hi,
I have a query that takes minutes to execute, even through there are about 300,000 records are being processed. I would appreciate any help with optimizing that query.
I have two tables: User and Usage. Table user has two fields: User_Id and Date_Created and a non-clustered index on User_Id. Table usage has two fields also: User_Id and Date_Used and non-clustered index on both fields. The User table is populated when the user registers. The Usage table is populated every time the user opens a document.
Here is what I need to do: get the number of users from the Usage table who opened a document at least once after they have registered during the last 30 days for each day in the time frame, where the time frame varies.
For example, if the time frame is 8/01/00 - 8/31/00, I need to get the following data:
date returns
---- -------
8/01/00 10 (10 users returned to the document between 7/2/00 and 8/1/00)
8/02/00 15 (15 users returned between 7/3/00 and 8/02/00)
.
.
.
8/31/00 20 (20 users returned between 8/1/00 and 8/31/00)
Here is my query:
SELECT [date],
(SELECT count(distinct user_id)
FROM usage u JOIN [user] ON u.[user_id] = [user].[user_id]
WHERE u.[date] BETWEEN usage.[date]-30 AND usage.[date]
AND u.[date]>[user].date_created
GROUP BY usage.[date])returns
FROM usage
WHERE [date] BETWEEN @date1 AND @date2
This query works fine, but too slow. We use MS SQL server 7.0.
Thank you,

I have a query which responds immediately when run however if I add an order by clause it takes 40 seconds. Below is the query with the order by clause
SELECT distinct Licenseplate, platetypecode.platetypecode, platetypecode.platetypecodeid
FROM Ticket INNER JOIN PlateTypeCode
ON PlateTypeCode.PlateTypeCodeID = Ticket.PlateTypeCodeID
ORDER BY licenseplate
The Ticket table contains approx. 11,000 records. I have created a nonclustered index for the licenseplate field, a 7 char varchar field.
Any suggestions for speeding up the query?

The following query is causing some problems because it's taking too long to complete. I looked at the estimated execturion plan and I am unsure why it appears to spend over 50% of its time doing a 'Bookmark Lookup' on on particular column (SRA_SR_ID in the S_EVT_ACT table). There is an index on the column - S_EVT_F14. I'm not sure if the query is using the index properly. What can be done to specifically improve this particular problem? In general, does anyone have some suggestions for optimizing the query as a whole?
Thanks in advance. Clive

I have a query that is taking too long to run. It take 14 seconds to return 6800 rows. However, if I move the query out of a stored proc, it takes 1 second. I want to understand this issue and ideally fix the stored proc case.
I've simplified my actual queries for readability.
-- @filter is value to filter against or NULL to return all records.
CREATE PROCEDURE queryPlayerStations(@filter INTEGER)
AS
SELECT * FROM MyTable
-- Other joins and query logic omitted for brevity
WHERE ((@filter IS NULL) OR (MyTable.Column = @filter))
GO
DECLARE @filter INTEGER
SET @filter = NULL
-- Takes 14 seconds to return 6800 rows. That's unacceptable performance
EXEC dbo.queryPlayerStations @filter
When I run the query directly in Query Analyzer, it runs very fast.
DECLARE @filter INTEGER
SET @filter = NULL
-- Takes ~1 second to return 6800 rows. That's great performance
SELECT * FROM MyTable
-- Other joins and query logic omitted for brevity
WHERE ((@filter IS NULL) OR (MyTable.Column = @filter))
When I put the parameters in the stored proc it runs fast.
CREATE PROCEDURE queryPlayerStations
AS
DECLARE @filter INTEGER
SET @filter = NULL
SELECT * FROM MyTable
-- Other joins and query logic omitted for brevity
WHERE ((@filter IS NULL) OR (MyTable.Column = @filter))
GO
-- Takes ~1 second to return 6800 rows. That's great performance
EXEC dbo.queryPlayerStations
Anyone have any ideas what I can do to improve the stored proc case?

Hi guys/gals
I have only just signed up, as I have a problem thats confusing me a lot
I have a page (classic asp - sadly) that displays a list of invoices for a certain customer
Each of these customers has fairly complex permissions system, but the page generates a list of invoices and values in 0.01 seconds
However in the while...do loop, for each invoice it checks a database table for "extra charges"..
This is a simple SQL query
"Select Sum(amount) from extra_charges where invoice_number=" & current_invoice_number
However each time it runs this simple select statement it takes 2 seconds - which causes the page to load in 70 seconds instead of 0.01
I am absolutely beyond confused. I have tried it in a stored procedure, and a direct ado query..
The table by the way is empty on my current test system, and one one other system has about 150 records in it. Both take the same time
Any help would be appreciated?
This is a MSSQL 2000 database I've inherited, I am usually a PHP/MYSQL developer - so im a little out of my field of expertise here

i want to have a like search in the following query.
SELECT DISTINCT TOP 200 a.AccountID,
a.AccountNumber,
c.CLI,
con.SurName,
addr.Address1 [Account Address],
addr.Postcode as [Account Postcode],
atp.Name AS Type,
cs.Code AS Status
FROM account_t a
INNER JOIN customer_t cust on a.customerID = cust.CustomerID
INNER JOIN AccountType_T atp on cust.AccountTypeID = atp.AccountTypeID
INNER JOIN CustomerStatus_T cs ON a.CustomerStatusID = cs.CustomerStatusID
INNER JOIN Contacts_T con on cust.MasterContactID = con.ContactID
INNER JOIN Address_T addr ON cust.MasterAddressID = addr.AddressID
LEFT OUTER JOINCLI_T c ON a.AccountID = c.AccountID
WHERE (c.CLI LIKE @CLI + '%')
AND (con.SurName LIKE @Surname + '%')
AND (addr.Address1 LIKE @Address + '%')
AND (REPLACE(addr.Postcode, ' ', '') LIKE @Postcode + '%')
AND c.DateArchived IS NULL
here all fields @CLI, @Surname, @Address, @Postcode are varhcar types...which is making this query very slow...is there any suggestion to improve this query?
thanks in advance

When I want to display the total records (#) in a webpage, it is very slow. When I try to remove the total records and show them per 20s, it responds very fast.
Any ideas?

What might be going on here? The Query is against a single table withsome criteria. The database is active with upto 200 connected usersand at peak times there are 10 or more active sessions. Most of thetime, the query comes back in milliseconds. Occasionally though, it itcan take a whole minute. I've been watching CPU, Memory, Disk. Noneof these appear to be the bottlenecking. (CPU usually below 10% andalways below 50%, pages/sec is 0, and disk % is low and does notspikes during hangs) I also checked to see if hangs were synching withTlog backups or other scheduled jobs, but that is not the case. Thebox has good hardware 4GB RAM and 2 CPU at 3.4 GHz. What could beholding this query up?Thanks for any ideas.Dave

This UNION query is very slow. With only 3,000 records in the Parent tableand 7,000 records in the Child table, it takes about 60 seconds to run andreturns about 2200 records.Any ideas on speeding it up?
