Query Taking Ages For No Apparent Reason
Jan 19, 2004
Hope someone can help me with this because its driving me potty!
I have a .NET script that sends really simple queries to SQL server that works perfectly 50% of the time but for the other 50% it takes ages (2-3 minutes) and then fails, I'm assuming because it times out. I then check the SQL by excecuting it via query analyzer and it again takes ages but will work eventually (I'm assuming because this bypasses the timeout settings, but changing these isn't on).
This happens randomly, the scripts will be working fine and then fail a few times before magically working again!
Any ideas? Perhaps some database features that commonly cause this problem? The problem only occurs with one database, all our others are fine but we can't spot any differences!
Any help or tips would really be appreciated.
Thanks.

Hi,
I hava a JAVA application that updates a SQL2000 (SP3a)database.
The application handles different types of "jobs" which effectively update the DB.
One job in particular appears to block all subsequent jobs. It comprises of a large amount of inserts/updates in a single transaction. This is necessary as it is an "all or nothing" scenario - so we cannot break the transaction into smaller ones. The transaction appears to succeed as it reaches the COMMIT TRAN statement without error.
However the records do not get written to the database.
EM indicates a large number of locks held on the tables accessed by the transaction and these do not get released.
Using the SP sp_blocker_pss80, the blocking SPID has a waittime of 0 and a waittype of 0x0000 - the lastwaittype is WRITELOG and its status is AWAITING COMMAND
I am using MS SQLSERVER JDBC Driver SP2 (considering using jTDS)
I have tried
- increasing Transaction Log size
- Moving Transaction Log to a separate Disk
- Reducing Isolation Mode to Read Uncommitted
- Set AutoCOMMIT to true
- set Close Cursor on COMMIT
- set SelectMethod to Direct - (we use Cursor by default)
None of these have succeeded in fixing the issue.
The job will succeed if it is the first/only job to access the database.
But if another job precedes it - then the blocking occurs.
I have verified that the preceding job only holds shared dataabase locks
before the blocking job is run.
Each job will use its own JDBC connections to access the database for reading
purposes, but all of the writing goes through the blocking SPID.
Any ideas?
Thanks, Liam

In the master database for a SQL Server instance I noticed the dt... objects (procedures, etc.) in create date of today about 7 minutes before I looked in sysobjects. No changes have been made to that instance for months. Also in other cases I noticed the same thing just different dates for each instance. Any ideas on why the dates would change?

Hi folks,Hopefully this is a simple fix, but I keep getting Syntax error withthis statement in an MS SQL DTS statement and in Query Analyzer:Update A Set A.deptcode = A.deptcode,A.type = A.Type,a.TotalExpenseUnit = (a.LaborExpenseUnit + a.OtherExpenseUnit)Where a.Type in ('FYTD04', 'Prior Year','Budget')From Data_Unsorted A Join Data_Unsorted B OnA.deptcode = B.deptcode and A.type = B.TypeBelow is the error from Query Analyzer:Server: Msg 156, Level 15, State 1, Line 5Incorrect syntax near the keyword 'From'.Where do I place my Where..In statement since I only want to limit theUpdate to run for items where a.type is FYTD04, Prior Year, or Budget?Thanks,Alex.

Hello there. I've been debating the best way to store the age of a ticket in a queue. Here's a little overview:
The application has a form that has users enter the current count and oldest ages of tickets in several queues. The format in the application they pull this data from stores it as Day:Hour:Minute (0:04:59)
The first time around, I stored them as datetime. But since you can't store a Day as zero (some tickets may be 0 days, 23:54 Hours old) I stored the day as a year. Well that proved to be stupid, because the averages in reports were way off. Next I stored the age as text, like this: 10459 (1 Day, 04:59 Hours old). Now my problem is when using that number in a report, I have to convert it to decimal and multiply the day by 24 and add it to the hour, just so they will be weighted correctly.
This is a mess... and I've searched all over the internet for examples, but every search result is for storing a persons age, not the age of a ticket.
Any one have any ideas?

I have the below query which returns thousands of records. can I optimize the returned result set faster without changing the structure of the database?
SELECT dbo.tblComponent.ComponentID, dbo.tblComponent.ComponentName, dbo.tblErrorLog.ShortErrorMessage, dbo.tblErrorLog.LongErrorMessage, dbo.tblErrorLog.LogDate, dbo.tblErrorLevel.Description,dbo.tblErrorLog.ErrorLogIDFROM dbo.tblErrorLevel INNER JOIN dbo.tblErrorLog ON dbo.tblErrorLevel.ErrorLevelID = dbo.tblErrorLog.ErrorLevelID INNER JOIN dbo.tblComponent ON dbo.tblErrorLog.ComponentID = dbo.tblComponent.ComponentID

Hi,
I am running this query and it is taking over 3 minutes.
"select * from table1 where CONVERT(varchar(10),dated,5) = '13-09-01' "
Table1 has a column called dated which is datetime datatype.
Any suggestions how can i optimize this query?I tried Non-clustered index on Dated column and time came down to less than 3 but still more than 2min.
TIA.

update a set PROJ_START_DT = b.PROJ_START_DT, PROJ_END_DT = b.PROJ_END_DT
from WPData a left outer join b on a.Proj_ID = b.Proj_ID -- join up and update

Below is my query which is taking a long time to execute, DB is SQL Server 2005 through a web Application
I have downloaded the latest MS SQL 2005 driver 1.xxx and still the query takes long to execute
The Description field is a Full_text indexed catalog column
the p.vendornumber is a primary key same with c.ID
Any one have an idea why it is taking this long to run
The Execution Time is: 13640 ms Which I think is very long
SELECT Upper(p.Type) Type,p.Modelname,p.partno,Upper(p.description) description,

Hey all! First post-- I apologize for the newbness of the question, but I'm having an issue with a basic query... here goes:
I want to calculate the percentages of statuses found from two tables. Let say T1 is my list of statuses:
T1
Passed
Failed
Not Completed
and T2 is the table where I derive my total # of statues for each id and how many in each status.
T2
ID, Desc, Status , numtimesinstatus
1, Test1, Failed, 3
1, Test1, Passed, 1
3, Blah, Failed, 5
3, Blah, Not Completed, 1
What I'd like to do is get the percentages for each available status in T1, from T2-- I can do this; however, I'm having trouble in the cases where a particular ID hasn't been in one of the status (in other words, calculating a 0%). What I'd like to get from these two tables is:
Result
ID, Desc, Status, %age
1, Test1, Failed, 75.0
1, Test1, Passed, 25.0
1, Test1, Not Completed, 0.0
3, Blah, Failed, 83.3
3, Blah, Passed, 16.67
3, Blah, Not Completed, 0.0
Can anyone shed some light? Thanks!

dear guys. i have this one problem, where the sql statements really took very long time to be processed. It took more than 1 minute, depending on the total data in the table. I guest this have to do with the 'count' statements. here is the code:
------------------------------------------------------------
$sql = "SELECT company,theID,abbs,A as Active,N as Nonactive,(A+N) as Total
FROM(
select distinct D.nama As company, C.domID As theID, D.abbrew As abbs,
count(distinct case when B.ids is NOT NULL THEN A.dauserid END) As A,
count(distinct case when B.ids is NULL THEN A.dauserid END) As N
FROM
tableuser A LEFT OUTER JOIN tabletranscript B on (A.dauserid=B.dauserid)
INNER JOIN thedommember C ON(C.entitybuktiID=1 AND C.mypriority=1 AND
C.entitybuktiID=A.dauserid)
INNER JOIN mydomain D ON (C.domID=".$getID.")
GROUP BY D.nama, C.domID, D.abbrew
ORDER BY company
)";
Hope any of you can simplify this statements into a query that doesnt take ages to be processed.
Thanks in advance....

I am not sure if I am in the correct location or if I should be in the SQL forum but here is my question:
I have an update statement that goes out through SQL 2000 through a local linked server to another SQL 2000 server on my machine. When I run the update in Query Analyzer it takes less than a second. When I run it in my C# code using the SqlCommand object and parameters it takes me ~23 seconds. If I remove one of the parameters it goes down to ~15 milliseconds. Has anyone heard of this happening?
The parameter that I remove is a simple char(10) column that isn't the primary key and is used in the WHERE statement. There isn't an index on the field.
23 Seconds
Update table Set column = @val WHERE field = @field AND other = @other
15 milliseconds
Update table Set column = @val WHERE field = 'values' AND other = @other

I'm running a query (see below) on my development server and its taking around 45 seconds. It hosts 18 user databases ranging from 3 MB to 400 MB. The production server, which is very similar but with only 1 25 MB user database, runs the query in less than 1 second. Both servers have been running on VMWare for almost 1 year with no problems. However last week I applied SP 2 to the development server, and yesterday I applied Critical Update KB934458. The production server is still running SQL Server 2005 Standard SP 1. Other than that, both servers are identical and running Windows 2003 Server Standard SP 1. I'm not seeing this discrepancy with other queries running against user databases.

Hi
I have one stored procedure and its taking 10 mins to execute. My stored procedure has 7 input parameters and one temp table( I am getting the data into temp table by using the input parameters) and also I used SET NOCOUNT ON. But if copy the whole code of the SP and execute that as regular sql statement in my query analyzer I am getting the result in 4 seconds. I am really puzzled with this.
What could be the reason why the SP is taking more than query,Unfortunately I can't post the code here.
Thanks.

Hey all, i'm making the pages meta keywords on my site dynamic, and i was wondering is there is a string, for example "Dell 17" Monitor Brand New", that would split it into each word for the meta keywords. example "Dell, 17", Monitor, Brand, New" (and possibly to not put a comma on the last word?)

We are experiencing an intermittent locking or hanging problem on our SQL Server (at the application level on the clients) and it has gotten worse very recently.
I haven't seen any processes that appear to be locked yet but I noticed that we don't have a lot of space available (the database is 1.4 gigs and we have about 245 megs available).
If this is inadequate disk space, could that be causing an apparent locking problem?
Thanks in advance for any help.

Hi,
I use SQL Server 2000 as a backend database for my Access Front end. It has been working fine for months with no problems.
This morning I arrived in work to find a problem with a table called "TimeSheets". If I try to access the table through Access I get an ODBC timeout error. Likewise, if I open the table in Enterprise manager, it opens fine, but any sorts or if I try to go to the last record, it returns the following error: "[Microsoft][ODBC SQL Server Driver] Timout expired".
So I tried to query the table in SQL Query Analyzer. Everytime it freezes on record 15,936. The table holds 17,643 records.
I tried running DBCC CHECKTABLE ('Timesheets'), and get the following message:
DBCC results for 'Timesheet - Item'.
There are 17643 rows in 401 pages for object 'Timesheet - Item'.
DBCC execution completed. If DBCC printed error messages, contact your system administrator.
I can't see any error messages, but by now I'm reaching the limit of my knowledge of SQL Server.
So, can anybody please help me with this? Any suggestions why my table has apparently become corrupted? Any suggestions how I might fix it?
Thanks a lot for any help

SQL Server 2005 SP2 (build 3054)Consider the following scenario:- A complex multi-statement table valued function is created. Let's callit dbo.tfFunc(@Param1, @Param2)- A SELECT statement is executed, that calls the above function twice,each time with a different set of parameters. In pseudocode:SELECT <column list>FROM dbo.tfFunc(1, 2) AS f1<some JOIN operatordbo.tfFunc(3, 4) AS f2ON f1.col = f2.colINNER JOIN dbo.Table1 AS t1ON ...etc.The exact statement is probably irrelevant, as long as the same table-valued function is called twice (I have observed the issue in two verydifferent statements calling the same function). The statement isexecuted in a SNAPSHOT isolation level transaction, although this mayalso be irrelevant.- The statement continues executing for a long time. If sp_who2 is run atthat time, the following row is returned for the statement connection(only relevant columns are shown):SPIDStatusBlkByCommandCPUTimeDiskIOLastBatch63 SUSPENDED63SELECT2928268308/31 18:17:37The statement appears to be blocked by itself. If sp_lock is run at thattime, the following rows are returned:spiddbidObjIdIndIdTypeResourceModeStatus63213166246410TABSch-SGRANT63213166246410TABSch-MWAITIt appears that SQL Server waits indefinitely trying to obtain a schema-modification lock on a resource which already has a schema-stability lockplaced on it by the same connection.The following is pure speculation, but it seems reasonable to assume thatthe server has materialized the result of the first call to the functionusing a temporary table in tempdb, and is trying to materialize theresult of the second call using the same temporary table (same ObjId insp_lock results).I do not know why this does not cause a deadlock error.Unfortunately, I do not have a simple repro script for this. The actualcode is rather complex. While I can devise a workaround, this does looklike a bug. I am posting it here before submitting a bug on Connect, incase anyone can shed some light. Thanks.--remove a 9 to reply by email

We have created a multithreaded application that reads result sets from MS SQL Server (both 2000 and 2005). The MS SQL Server app and our app reside on the same machine. We are using the latest version of ODBC32.DLL (3.526.1830.0) and SQLSRV32.DLL (2000.86.1830). Our application is written in C++ using the Visual C++ 6.0 compiler and libraries. Our app runs as a service, therefore the apparent memory leak is a real problem. Our app needs to run on a server in a closet without human intervention.
We are kicking off many user threads that each can read from the database tables. Each of the reads from the database occurs within a critical section to minimize the threads stepping on each other. The ODBC interface class follows all the steps defined in the ODBC application developers documention (see code below).
We see or app memory steadily increasing over time (we used PerfMon to monitor Private Bytes and Virtual Bytes, per ODBC documentation). If we terminate the threads which are retreiving the result sets, the memory drops back to the level noted prior to starting the threads.
The code below is admittedly inefficient, however, it should not leak memory when accessing the database. Note that it works very well, returns the result sets that we expect exactly.

Found some bad behavior in the 2005 Management Studio Import and Export Wizard.
In the Select Source Tables and Views box, I selected multiple objects, and then clicked Edit Mappings.
The Transfer Settings dialog box appears, and states: "Define the settings that can be applied to all selected table transfers."
I selected the "Delete rows in existing destination tables" option to overwrite the existing data. But Management Studio DID NOT DELETE THE ROWS IN THE EXISTING TABLES. Instead, the records were appended to existing data, wreaking havoc on our month-end accounting system.
This happened multiple times, and occured even though the final screen confirmed that existing records would be deleted in each of the individual tables.

I used the SQL Server 2005 Upgrade Advisor to upgrade from SQL Server 2000 Enterprise to 2005 Standard. The only complaint I got concerned DTS packages, but I had none anyway. When I open SQL Server Management Studio, I can run queries, but they're against tables in the old 2000 databases. The SQL engine and Server agent are version version 8.0. Not surprising that new TSQL statements like 'BACKUP SERVICE MASTER KEY TO FILE' won't work.
Do I have to uninstall my previous version before upgrading?
Thanks.

On SQL 2012 (64bit) I have a CLR stored procedure that calls another, T-SQL stored procedure.
The CLR procedure passes a sizeable amount of data via a user defined table type resp.table values parameter. It passes about 12,000 rows with 3 columns each.
For some reason the call of the procedure is verz very slow. I mean just the call, not the procedure.
I changed the procdure to do nothing (return 1 in first line).
So with all parameters set from
command.ExecuteNonQuery()to
create proc usp_Proc1
@myTable myTable read only
begin
return 1
end
it takes 8 seconds.I measured all other steps (creating the data table in CLR, creating the SQL Param, adding it to the command, executing the stored procedure) and all of them work fine and very fast.
When I trace the procedure call in SQL Profiler I get a line like this for each line of the data table (12,000)
SP:StmtCompleted -- Encrypted Text.
As I said, not the procedure or the creation of the data table takes so long, really only the passing of the data table to the procedure.

When I design package under ssis, I always use execute sql task to replace OLE DB Command. Normally, I use staging tables to get all data from data source,then modify or generate some columns on the staging tables according to bussiness rules using execute sql task, Finally,transfer to data destination. And execute sql task is more effiecient than OLE DB Command. I suppose there's reason for using
OLE DB Command. But I don't know. So what's the reason to use OLE DB Command?

I am having difficulty in identify my deadlock reason. So, please give me some hints.
In my application, I have 2 standard functions. One for transaction creation and one for reporting. The strange problem is I seldom / never got any deadlock witht the transaction creation. Instead, I got deadlock problem with the reporting.
In the reporting function, I only use select and aggregate function. Why will deadlock be raised? Can someone give me an example why such deadlock happened?
Thanks in advance.

SQL Server is terminating due to 'stop' request from Service Control Manager.
Any help?

Hi,
I have a package that just won't run from a job.
To test the problem, I created a very simple package. All it does is load a simple text file to a table on the local server.
I set protection level to "encrypt sensitive with password", and set the password. I changed the creator name to the SQL Server Agent Account. (don't know how to change the GUID?)
It runs fine from BIDS and msdb storage. But if I run it from the job, it fails with:
Executed as user: DOMAINUSERNAME. The package execution failed. The step failed.
No logging occurs, even though I have set the package to log, which seems to indicate it's not even getting as far as starting the package. I've restarted all the services.
I tried running this package from a job on ANOTHER server and it works, no problem. There's just something going on with this other server where it won't run from the job... both servers use the same SQL Server Agent account.
I've consulted http://support.microsoft.com/kb/918760 and it talks about this problem but I have everything set correctly... never had this problem before... seriously.
HELP

While investigating performance problems within an application recently I carried out some tests using SET SHOWPLAN ON.
I had a query like this within a stored procedure:
SELECT MAX(X) FROM Y WHERE Z LIKE @MYVAR
Where @MYVAR was passed in. I discovered that SQL Server did a Table Scan even when Z had an index on it. A problem with 200,000 rows!
If I said
SELECT MAX(X) FROM Y WHERE Z LIKE 'HELLO%'
(i.e., used a constant instead of a variable) SQL Server did use the index correctly and did not do a table scan.
I got around this by rewriting my statement:
SELECT MAX(X) FROM Y (INDEX=MYINDEX) WHERE Z LIKE @MYVAR
in other words by manually specifying the index I had created on the Z column.
Hope this helps someone.
