Please Help! Suspended/Stalled Query

Mar 10, 2007

Hi,

I am having a problem with one package that attempts to do a join on two large tables. Within the data flow task control is the ole db source control which has the initial query that joins and filters the tables.

The total number of rows that should be returned are about 80-90million. Running this in debug mode shows the number of rows read/inserted into the ole db destination and it always hits the about the same number of records where it just stops/stalls/suspends around 75 million. I have read some possible solutions such as changing the max degrees of parrallelism but that has not worked.

I am currently using SQL Server 2005 64bit SP2 on a 64 bit platform. This is the only package that does anything like this and I am at my wit's end with this problem.



Please help!



Thanks,
Cheston

Trouble Install SQL Server Express (2005). Stalled On Current Component Is Installing

Mar 21, 2007

Hi


I am installing Visual Studio 2005 Professional Edition. Everything goes well until the installation of SQL Server Express occurs. SQL Express installation progresses fine until very end of the installation. At that point it becomes stuck.

The installation says "Current component is installing" and is stuck on that message. The installer does not seem to be frozen as the picutres changes. However CPU usage for the setup processes is 0.

I have disabled all virus scanning software already.


Any help is apprceciated.

Suspended Status

Sep 25, 2007



Hi All,

Using SQL Server 2005 w/ SP2 I have a simple select query with a parameterized WHERE clause that in Management Studio runs nearly instantly, everytime. Using the same login, when I run the same query using SQL RS the results (only 6 rows) takes upwards of 5 minutes. If I look at the Activity Monitor, it shows the process as suspended and indicates a CXPACKET. Everything I have read on the forums about this indicate it is an issue with not having SP2 , which I do. Or a 64 bit version, I have 32. Or for large bulk updates, I am doing a very simple select. Does anyone have any clue on this?

regards
Bill

Calculating Length Of Time A Ticket Was Suspended

Mar 7, 2007

I'm trying to find a solution to for a report i am building and was hoping that some of you will share your expertise with me. Basically, I need to work out how long an Incident Ticket was suspended (ie it's status is "on hold").

The data is stored something similar to the following...

Ticket Date Status
------ ---- ------
333 14/03/2005 10:24:19 "to on hold"
333 14/03/2005 15:23:01 "from on hold"
334 14/03/2005 11:14:11 "to on hold"
334 14/03/2005 16:26:15 "from on hold"
335 15/03/2005 10:10:15 "to on hold"
335 15/03/2005 11:15:35 "from on hold"
335 15/03/2005 13:26:10 "to on hold"
335 15/03/2005 14:30:59 "from on hold"
335 16/03/2005 14:00:05 "to on hold"
335 16/03/2005 16:45:15 "from on hold"
336 16/03/2005 10:10:15 "to on hold"
336 16/03/2005 12:45:12 "from on hold"

This is the result i'd like to see....

Ticket Start Hold End Hold Time Suspended
------ ---------- -------- --------------
333 14/03/2005 10:24:19 14/03/2005 15:23:01 datediff(...
334 14/03/2005 11:14:11 14/03/2005 16:26:15 datediff(...
335 15/03/2005 10:10:15 15/03/2005 11:15:35 datediff(...
335 15/03/2005 13:26:10 15/03/2005 14:30:59 datediff(...
335 16/03/2005 14:00:05 16/03/2005 16:45:15 datediff(...
336 16/03/2005 10:10:15 16/03/2005 12:45:12 datediff(...

Has anybody done something along the same lines? If so, could you point me in the right direction?

Thanks in anticipation

2005 BACKUP LOG Process Goes To Suspended State For Every DB

Dec 4, 2007

Hello. We recently ran into extremely large transaction log sizes on our SQL 2005 box...turns out they were not being backed up. After doing some research, I found that they should be backed up very frequently in order to kee their sizes down. I kind of inherited the mess, but got three maintenance plans set up:


FULL Backup that runs weekly

DIFFERNTIAL Backup that runs nightly

TRANSACTION LOG backup that runs hourly
However, since I implemented the plans there has been high CPU utilization at all times. I finally figured out what was causing it today...the BACKUP LOG process is hanging in "Suspended" mode when I view processes. I have to manually kill them to release the CPU utilization.

How can I trace the cause of the hang? Is there a better way to backup/truncate the log files?

Regards,

Matthew

SQL Server 2005 SP2 Cannot Be Installed Because The Database Engine Setup Remains In Suspended Installation Mode

Feb 23, 2007

SP2 refuses to install for the Database Engine because €śthe previous upgrade did not complete€?, i.e. it detects a suspended installation. The same thing happened to me when I installed SP1. I then remember opening the maintenance dialog and completing the setup, after which SP1 installed just fine.

When I try to do the same thing this time, I€™m presented with the €?complete the suspended installation€? option, which when I run it reports the installation completed successfully. However, in reality the installation still remains in suspended mode for whatever reason. If I reboot and open the maintenance dialog, I€™m still presented with the €?complete the suspended installation€? option. I€™ve even tried to run it more than once, but it doesn€™t help. Needless to say, SP2 still refuses to install.

I don't know why the installation is in a suspended state. I know every part of SP1 installed successfully in the end, and the computer never crashed during the installation. I've been using it every day since then, without any problems. All other parts of SP2 did install successfully.

I created a feedback entry on Microsoft Connect, where you can find the log files created by Windows Installer. The URL is:
https://connect.microsoft.com/SQLServer/feedback/ViewFeedback.aspx?FeedbackID=259606

Any ideas what I can do to resolve this problem?

SQL Server 2008 :: Backup Running Long And Backup Threads Show Suspended

Feb 18, 2015

SQL Server 2008 r2 - 6 GB memory...I attempted a backup on a 500GB database but it was taking way too long. I checked the resources on the box and saw the CPU at 100%. I checked the SQL Server activity log and saw a hung query (user was not even logged on) that had multiple threads so I killed it and now the CPU utilization is back to normal.

Trouble is, now all of the threads in the activity monitor for the backup show 'suspended' and the backup appears to be not doing anything.

Error: 8624 Internal Query Processor Error: The Query Processor Could Not Produce A Query Plan.

May 24, 2007

SQL 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).

SQL Server 2012 :: Adding Count To Query Without Duplicating Original Select Query

Aug 5, 2014

I have the following code.

SELECT _bvSerialMasterFull.SerialNumber, _bvSerialMasterFull.SNStockLink, _bvSerialMasterFull.SNDateLMove, _bvSerialMasterFull.CurrentLoc,
_bvSerialMasterFull.CurrentAccLink, _bvSerialMasterFull.StockCode, _bvSerialMasterFull.CurrentAccount, _bvSerialMasterFull.CurrentLocationDesc,
_bvSerialNumbersFull.SNTxDate, _bvSerialNumbersFull.SNTxReference, _bvSerialNumbersFull.SNTrCodeID, _bvSerialNumbersFull.SNTransType,
_bvSerialNumbersFull.SNWarehouseID, _bvSerialNumbersFull.TransAccount, _bvSerialNumbersFull.TransTypeDesc,

[code]...

However, as you can see, the original select query is run twice and joined together.What I was hoping for is this to be done in the original query without the need to duplicate the original query.

Query Fails With Invalid Column Name But Succeed As Sub-query With Unexpected Results

Sep 22, 2015

-- The 3rd query uses an incorrect column name in a sub-query and succeeds but rows are incorrectly qualified. This is very DANGEROUS!!!
-- The issue exists is in 2008 R2, 2012 and 2014 and is "By Design"

set nocount on
go
if object_id('tempdb.dbo.#t1') IS NOT NULL drop table #t1
if object_id('tempdb.dbo

[code]....

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,

SQL Server Admin 2014 :: Estimated Query Plan For A Stored Procedure With Multiple Query Statements

Oct 30, 2015

When 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,
Scott Chang

SP To Perform Query Based On Multiple Rows From Another Query's Result Set

Nov 7, 2007

I 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!

Query Designer Encountered A Query Error Via Enterprise Manager

Jan 7, 2002

I am trying to run queries against any of the user tables in my MS SQL 7.0 database. I get a message the Query Designer encountered a query error.
We have tried rebooting the SQL Server and I am still getting these messages. Also, the SQL error logs look fine - all database
maintenance are running successfully including the DBCCs which show no errors. Any help would be greatly appreciated as we are to go
into production in a few days.
