EXtremely Long Time In Execution Query

Mar 21, 2007

Hi all,

I have a query, rather complex one to deal with more than 1 million rows, used to run 40 minutes in SQL Server 2000 in query analyzer. Now, it has been 10 hours in SQL Server 2005 in management studio. And still has not finished yet! Anything can go wrong here. Basically nothing changes, except for I have my server upgrade from SQL Server 2000 to SQL Server 2005. Seems something is wrong crazy in SQL Server 2005. Any suggestions?

Thanks,

Ning

Long Execution Time When Using Parameter

Dec 20, 2007

Hi all,

If I use the following query for a Dataset and the execution takes a few seconds to show results



SELECT *

FROM dbo.ICParameter

WHERE (PatientID = @ID ) AND (LogTime > DATEADD(day, -1, GETDATE()))

ORDER BY LogTime


If I replace '99010200101' with @ID and enter '99010200101' when prompted for ID, the execution takes forever. Actually I have never got any results even after waiting for 10 minutes.

Could anyone shed some light on this?

Thanks in advance.

Extremely Long Lines Of Text

Sep 25, 2006

I have a dtsx package that works fine with one exception. When I open the dtsx package in BI, it gives me the following message:

Document contains one or more extremely long lines of text. These lines will cause the editor to respond slowly when you open the file. Do you still want to open the file?

When I respond yes, the package opens and I can edit or execute with no problem. Still, I want to understand what could cause this message to occur and, more importantly, how I can get rid of the message. When I try to simply execute the package I still get the same error and it seems this will be a problem for trying to run the package from SQL Server agent.

It seems likely to me that this message refers to the dtsx file (in xml format) itself. Does that make any sense?

Error - Document Contains One Or More Extremely Long Lines Of Text

May 6, 2008

Hi,

I've created a dataset with 27 measures and 20 query parameters. When attempting to load the report containing this dataset I'm shown the message;

'Document contains one or more extremely long lines of text. These lines will cause the editor to respond slowly when you open the file. Do you still want to open the file.'

If I do open the file it does indeed respond very slowly or even hangs.

I can manually format the XML code but amending the code in any way (i.e. using the layout designer to move a chart) removes my formatting and re-introduces the problem.

Are these an unreasonable amount of measures / parameters?

Environment;
VS2005 v8.0.507
MSSQL 2005 9.00.1399.06 Build 3790 SP2
Windows Server 2003 SP2

Many thanks.

CTE Query - Long Load Time

Dec 5, 2014

I have a CTE query that is used to fill in nulls on a history table. The With statement executes just fine. sub 2 seconds on 974 records, however the main query is what's turning the whole query into a turtle. I know that it's the looping that it's doing there that is causing the slow down, but I'm just not sure how to fix it. I've tried inserting it into a temp table, refactored the code a hundred times, but nothing seems to be working.

Code is below and the execution plan is attached.
Server Version: 12.0.2342.0
Enterprise: 64bit

;WITH BuildTable
AS ( SELECT [GEGTH].[ID]
, [GEGTH].[Changed By]
, CAST( [dbo].[GetWeekStarting] ([GEGTH].[Changed Date] , 2 ) AS DATE) AS WeekOf
, [GEGT].[Title]

Dm Query Taking Long Time

May 16, 2007

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.



use MyDatabase

GO

select db_name(database_id) as 'Database', o.name as 'Table',

s.index_id, index_type_desc, alloc_unit_type_desc, index_level, i.name as 'Index Name',

avg_fragmentation_in_percent, fragment_count, avg_fragment_size_in_pages,

Does anyone see this problem?

How To Optimize Following Query For Execution Time

Limit Query Execution Time

Aug 15, 2007

Hello,I ran a query that I thought would take an hour, but instead took 14hours to run. The consequence was it bogged down our data warehouseand the overnight build was adversely impacted.Is there a local setting I can set to limit the execution time myquery will take? I dont want to have a server setting and impact otherqueries, just the one I am running.I know there will be people asking about the 14 hour build and what isit doing and so forth. I will address that but I also look to thesesituations as a learning opportunity.Thanks in advance.Rob

Issue Related To Execution Time Of Sql Query

Apr 30, 2008

I have created 2 tables in a database which are mostly similar, the table1 will execute with more speed (take only less than or equal to 1 sec) but the table2 will take 4 or 5 secs to execute the query,moreover the similar datas was presented in both the tables. the eg:- query that i have executed is select max(c_code) from table1 and select max(c_code) from table2, the first one take less than 1 sec and the second one take more than 4 or 5 secs, also there is a procedure i hve written to update both the tables, and i got the time out error, if the table1 alone is updated using the procedure it is OK but the table2 alone is updated using the procedure the time out error will be shown, pls reply the reason for this problem as early as possible, it will be a grateful if anybody reply for this trouble?

Execution Time For Stored Procedure Vs. Query Analyzer

Feb 21, 2002

HI,
I have an interesting situation. I have created a stored procedure which has a select union query and it accepts some parameters. When I execute this procedure it takes 8 minutes. When I copy the script in stored procedure and run it directly in Query Analyzer it takes 2 1/2 minutes?? Same numbers of rows are returned either way in the result set with about 13,000.

I cannot figure this out and it is almost the same thing except that in Query Analyzer I declare the parameters variables and its values?

Any feedback would be appreciated!

Thanks in advance...

Query Analyzer -&> Subtree Cost Vs. Execution Time

Jul 14, 2004

I am using a stored procedure that is behaving badly - the subtree cost is about 2000 and it takes between 3-4 seconds to run, and sometimes it takes over a minute to run. I have made some optimizations that cause the stored procedure to run in generally under 1 second (at most under 2 seconds), but the subtree cost of it jumps to 4000!! All of this while the server was experiencing similar load (the tests were done within minutes of each other).

I know that the subtree cost is a way to gauge the performance of a query against other queries, but I have typically seen the cost go in the same direction as the execution time (they both go up or the both go down).

How does SQL Server determine the cost (I know that is based on statistics, but I was wondering if anyone had more details)? Is it more important to have a lower subtree cost, or a lower execution time? Am I going to get into trouble later with this high subtree cost?

I would appreciate any help on this matter.

SQL Server 2012 :: Saving Query Text / Execution Time And Rows Count

Right now I've created a sp and a job that runs every 1 milliseconds but I can't figure out how to get execution time and rows count. Another problem with this is that if the query takes too long I end up with several rows in my table.

It Takes A Long Time To Insert The First Record Each Time When The Program Start

Dec 15, 2006

I am using VS2005 (VB) to develop a PPC WM5.0 Program. And I am using SQLCE 3.0. My PPC Hardware is in 400MHz.

The question is when the program try to insert the first record into sdf database after each time the program started. It takes a long time. Does anyone know why and how can I fix it?

I will load the whole database into a dataset when the program start and do all the "Insert", "Update", "Delete" in this dataset and fill it into database after each action.

        cn.Open()
        sda = New SqlCeDataAdapter(SQL, cn) 'SQL = Select * From Table
        scb = New SqlCeCommandBuilder(sda) 
        sda.Update(dataset)
        cn.Close()

I check the sda.update(), it takes about 0.08s for filling one record into database normally. But:

1. Start the PPC Program

2. Load DB into dataset

3. Create a ONE new record in dataset

4. Fill back to DB

When I take this four steps everytime, the filling time is almost 1s or even more!

Actually, 0.08s is just a normal case. Sometimes, it still takes over 1s to filling back a dataset which only inserted one record when the program is running. (Even all inserted records are exactly the same in data jsut different in the integer key)

 However, when I give up the dataset and using the following code:

            cn.Open()
            Dim cmd As New SqlCeCommand(SQL, cn) ' I have build the insert SQL before (Insert Into Table values(XXXXXXXXXXXXXXX All field)

           cmd.CommandType = CommandType.Text
            cmd.ExecuteNonQuery()
            cn.Close()
            StartTime = Environment.TickCount

 I found that it is still the same that the first inserted record takes more time, but just about 0.2s. And the normal insert time is around 0.02s. It is 4 times faster!!!

Possibly Extremely Simple SQL Query

Jan 27, 2004

Right, I'm no SQL programmer. As I type this, I have roughly the third the hair I had at 5 o'clock last night. I even lost sleep over it.

I'm trying to return a list of records from a database holding organisation names. As I've built a table to hold record versions, the key fields (with sample data) from a View I created to display this is as follows:

record_id-----org_id-----live-----version
====== ===== === =====
1-------------1----------0----------1
2-------------2----------0----------1
3-------------1----------1----------2
4-------------2----------0----------2

as you can see the record id will always be unique. record 3 is a newer version of record 1, and 4 of 2. the issue is thus: i only want to return unique organisations. if a version of the organisation record is live on the system (in this case record id 3), i want to return the live version with its unique record id. i'm assuming for this i can perform a simple "SELECT WHERE live = 1" query.

however, some organisations will have no live versions (see org with id 2). i still wish to return a record for this organisation, but in this case the most recent version ie version 2 (and again - its unique record id)

in actual fact, it seems so much clearer when laid out like this. however, i feel it's not going to happen this end, and so any help would be greatly appreciated.

many thanks in advance,

phil

Timeout Errors When Execution Long Running Procedure

Apr 21, 2007

When I execute a long running procedure, I get timeout errors when other users try to execute other procedures with UPDATE or INSERT statements.



I suspect that the other procedures are trying to execute DML statements on tables that are locked by the long running procedure.



I have a sharred trigger on all my tables that creates and updates records in tables AuditLogDetails and AuditLogParent for keeping a log of modifications. I suspect that tables AuditoLogDetails and AuditLogParent are locked by the long running procedure.



How can I change the LOCKING behavior of the long running procedure to fix the time out errors that I get?

SQL 2012 :: Long Delay Between Job Start And Actual Package Execution

May 7, 2014

I have problems sometimes with a package.

There is and SQL Agent job that starts a package (from a file system using cmd command). Usually job takes 8-10 minutes. But sometimes it get stuck for a long time (1+ hour).

DTexec process can be found with procmon, but it seems it just not doing anything (And package is not logging to file Start of the execution) After long wait it just runs a package quickly.

I've moved a package to SSIS catalog to try to get more detailed logging, but with no luck.

Job starts at 1 PM, package execution starts at 1:49 PM. Without any messages about the execution in SSISDB log.

First I've thought it might be long validation problem, but when package executes validation messages are there and they perform quick.

First Time SSIS Long Time DTS

May 21, 2008

A few pointers would be appreciated.

I am looking at building multiple SSIS packages. There will be some similarities. Flexibility is of highest importance. The main packages will need to connect to SQL Server1 as a source and SQL Server2 as a destination to transfer over dimenion data from multiple databases. (other SSIS packages may need to use SQL Server2 as a source and SQL Server1 as a destination)

For a single dimension table containing column dim_id on the target server (SQLServer2). I need to pass the results of the following SQL and insert into SQLServer2.database.dim_table

select dim.id
from SQLServer1.database08.dim_table
union
select dim.id
from SQLServer1.database07.dim_table
union
select dim.id
from SQLServer1.database06.dim_table


Now next year the names of the databases on SQLServer1 will be database09,database08,database07!

Now so far my best thought is creating views in my destination SQL Server. So I need some way of dropping and recreating the views. Previously in DTS I would expect to see SQL Server connection that I could use as source and destination. Now I can see SQL Server destination but not source? Also How do I just use SSIS to run some SQL. i.e execute a stored procedure, drop and creat views?

Many thanks,
Ells
p.s Flexibility is the key, in the last three months all the ip and server names have changed more than once so need to be as flexible as possible.

SQL SP Takes Long Time To Run From VB.NET App

Nov 22, 2007

Hi all,

I have a stored procedure that is called from a VB.NET application that takes an enormously long time to execute. In the QA it only takes 10sec but in the application it takes ages. The stored procedure is as follows:

PROCEDURE NAME IS SPTOPTWENTYUSERS

SELECT TOP 20 STRUSERNAME,SUM(INTBYTESRECVD) AS INTDOWNLOAD FROM TBLISAWEBLOGS
WHERE DTELOGDATE BETWEEN @BEGINDATE AND @ENDDATE
GROUP BY STRUSERNAME
ORDER BY INTDOWNLOAD DESC

The code that runs it is as follows:

sSQLString = SPTOPTWENTYUSERS
Using cnn As New SqlConnection(GetPath)
Try
Dim cmd As New SqlCommand(sSQLString, cnn)
Dim dr As SqlDataReader

With cmd
.CommandType = CommandType.StoredProcedure
.CommandTimeout = 0
.Parameters.Add("@BEGINDATE", SqlDbType.DateTime)
.Parameters.Add("@ENDDATE", SqlDbType.DateTime)
.Parameters("@BEGINDATE").Value = dtpStartDate.Value
.Parameters("@ENDDATE").Value = dtpEndDate.Value
End With
cnn.Open()
dr = cmd.ExecuteReader

Any help on why this happens would be much appreciated.

thanks

It works fine in dev box, but when I place on shared hosting, and some people access it  crashed. The website can not be accessed. Hosting support told me maybe I need to reprogram my code. So anybody has solution for this problem ? Should I create new thread ?
