Multiple Table Joins Makes Query Go To Sleep
Jul 23, 2005Hello All & Thanks in advance for your help!Background:1) tblT_Documents is the primary parent transaction table that has 10fields and about 250,000 rows2) There are 9 child tables with each having 3 fields each, their ownPK; the FK back to the parent table; and the unique data for thattable. There is a one to many relation between the parent and each ofthe 9 child rows. Each child table has between 100,000 and 300,000rows.3) There are indexes on every field of the child tables (though Idon't believe that they are helping in this situation)4) The client needs to be presented a view that has 5 of the mainfields from the parent table, along with any and all correspondingdata from the child tables.5) The client will select this view by doing some pattern-matchingsearch on one of the child records' detail (e.g. field-name LIKE%search-item% - so much for the indexes...)Problem:When I do the simple join of just the parent with one of the children,the search works *fairly* well and returns the five parent fields andthe corresponding matching child field.However, as soon as I add any one of the other child records to simplydisplay it's unique data along with the previously obtained results,the resulting query hangs.Is the overall structure of the tables not conducive to this kind ofquery? Is this a situation where de-normalization will be required toobtain the desired results? Or, more hopefully, am I just an idiotand there is some simpler solution to this problem?!Thanks again for your assistance!- Ed

Pause The Current Batch?

Does TSQL (2005) have a way to pause the current batch for a given number of seconds? This would be helpful during testing.

Runtime Error After Some Pause
Apr 18, 2006Hello,
My users often view some report for some minutes and after that want to return to parent report.
If they did it after small time (~less than minute), everything is OK. But if this pause is above 1 minute they receive "Runtime Error" message and can only to go to homepage.
I think that this is some session time or something like that.
Am I right? How can fix it?
Thank you
Pause And Resume Mirroring
Dec 5, 2007
If we have a situation that the Mirror server is unavailable for a day....very unlikely, but it happens when servers are moved from one data center to another....Lets assume we are doing safety off (high performance mode)
Should we pause mirroring on the principal server?
When we pause, does the transaction log keeps growing ?
Can we backup the logs ?
If we don't pause mirroring
Does the transaction log keeps growing ?
Can we backup the logs ?
What we can expect we we bring online the mirror server next day! will there be any performanbce problems since mirroring will try to catch up....
Considering moving to mirroring from logshipping for our disaster recovery.
Thanks,
Status Lights (Red/Stop Green/Start Yellow/Pause)
Jul 16, 1998For some reason the status lights in my Enterprise manager are no longer working. I am connected to the databases, but because the indicator lights are not working, I can`t get a quick visual status of my servers.
Any way to get my lights back on?
SQL 2012 :: SSIS Automatic Pause And Manual Restart Options
Jun 25, 2014As part of an ETL process which takes several days I need to build in an auto pause on processing with no set time for restarting it again. So we cannot use the script..WAITFOR DELAY '00:01:00'
Apparently the Loop is not an option as it uses too much CPU.We need to run a few manual checks and there is no way to determine the amount of time needed. After these check are done I need some way of resuming the package from where it stopped.
The obvious way probably is to build this into two separate packages but this would break the logical way our containers are being setup, in other words, it would make us break a container into two different parts in different packages.

Jan 24, 2007Hi,
Im currently running a website in conjuction with MSSQL Express. However at the moment the website/database seems to 'sleep' when no-one is using it, then there are huge dealays accessing the data while the database/website kicks in again. I tried to google this but truthfully i don't know what i am looking for. Does anyone have any ideas? Or whether this problem is Database or website driven? I thought there might be a control in the web.config but i haven't found a solution as yet!

Reporting Service Seems To Go To Sleep After A While...
Sep 11, 2007
My reporting server seems to go to sleep after some time of non-use. This is affecting the users who create reports at the start of the day. A report that takes 1 second to generate takes 11 seconds on first hit in the morning. After the initial "wake up" call, the report server generates the reports normally without any delay. Can I keep it awake the whole time? Is there a setting somewhere?

SSRS 2005 Goes To Sleep!
Jul 17, 2006Has anyone figured out why it takes about 30-60 seconds to load a report or even get the login webpage in SSRS2005?? This seems to happen in 2 situations. One, the server has just started up and its the first request for a report or the SSRS webpage. Two, no one has requested a report or a SSRS webpage for a while (say 30min, maybe less). Its like part of SSRS has gone to sleep. Is there anyway to keep this from happening??

Problem With Sleep Function In SSIS
Jun 22, 2006Hi,
I have a script task in SSIS which uses a sleep command. sleep(600000) which waits for 10 minutes. This works fine when i execute the package through GUI. But when i execute the same with Commandline, it does not work. Is there some thing which I have not set. I have also tried the Windows API call for sleep still it behaves the same way.
Any help??
Thanks in advance

Report Server Goes To Sleep....zzzzzzz
Jul 21, 2006The known issue about the report server going to sleep after being idle for a while is causing me a problem. I have set up a dummy sibscription to create and email a report every hour and also have set the IIS setting on the application pool the RS uses (shut down worker process after being idle for x mins, I have set this to 860!).
But the report server still goes to sleep and it can take up to 60 seconds for a report to start up.
What else can I set to reduce this problem?
SPID Goes To SLEEP Every Time I Run A DBCC Command
May 14, 2008So every time i run a DBCC command like DBCC SHOW_STATISTICS and DBCC INDEXFRAG, the query executes and goes on for ever. When i do a sp_who2 i notice that my DBCC SPID goes to sleep mode with high CPUTime and High DiskIO's. i also noticed that my server has no activity, no inserts, no updates and no select statements running by other users. Why cant i run a DBCC command?
You thoughts and suggestions are highly appreciated!

How To Repeat Delete Records And Sleep Awhile In T-SQL
Feb 14, 2008Hi:
I have one table in which there are almost 800,000 records, and I tried to delete them by SQL stored-procedure in which executing SQL like this: "delete from tablename where date='YYYYMMDD'", once I started this procedure, I noticed SQL server will take most of CPU resources in a short period, but that's not acceptable. and there are some other useful records in this table, we can't use Drop Table.
So my question is "can we delete 1000 records and then sleep awhile, and repeat until all these records are deleted !"
Any refernece will be appreciated, thanks!
Can We Pause Log Shipping, Bring Primary Db To Simple Recovery Model And Then Back To Full R Model?
Apr 25, 2008
We have the following scenario,
We have our Production server having database on which Few DTS packages execute every night. Most of them have Bulk Insert stored procedures running.
SO we have to set Recovery Model of the database to simple for that period of time, otherwise it will blow up our logs.
Is there any way we can set up log shipping between our production and standby server, but pause it for some time, set recovery model of primary db to simple, execute DTS Bulk Insert Jobs, Bring it Back to Full recovery Model AND finally bring back Log SHipping.
It it possible, if yes how can we achieve this.
If not what could be another DR solution in this scenario.
Thanks Much

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).

SQL Server 2012 :: Adding Count To Query Without Duplicating Original Select Query
Aug 5, 2014I 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,
Maurício
