Update On Machine Runs Immediately, Update On Linked Server Takes 8 Minutes
Jan 2, 2008
What's up with this?
This takes like 0 secs to complete:
update xxx_TableName_xxx
set d_50 = 'DE',modify_timestamp = getdate(),modified_by = 1159
where enc_id in
('C24E6640-D2CC-45C6-8C74-74F6466FA262',
'762E6B26-AE4A-4FDB-A6FB-77B4782566C3',
'D7FBD152-F7AE-449C-A875-C85B5F6BB462')
but From linked server this takes 8 minutes????!!!??!:
update [xxx_servername_xxxx].xxx_DatabaseName_xxx.dbo.xxx_TableName_xxx
set d_50 = 'DE',modify_timestamp = getdate(),modified_by = 1159
where enc_id in
('C24E6640-D2CC-45C6-8C74-74F6466FA262',
'762E6B26-AE4A-4FDB-A6FB-77B4782566C3',
'D7FBD152-F7AE-449C-A875-C85B5F6BB462')
What settings or whatever would cause this to take so much longer from the linked server?
Edit:
Note) Other queries from the linked server do not have this behavior. From the stored procedure where we have examined how long each query/update takes... this particular query is the culprit for the time eating. I thought it was to do specefically with this table. However as stated when a query window is opened directly onto that server the update takes no time at all.
2nd Edit:
Could it be to do with this linked server setting?
Collation Compatible
right now it is set to false? I also asked this question in a message below, but figured I should put it up here.

UPDATE CD SET col1=SR.col1,col2=SR.col2,col3=SR.col3,col4=SR.col4,col5=SR.col5,col6=SR.col6,col7=SR.col7,
col8=SR.col8,col9=SR.col9,col10=SR.col10
FROM LNKSQL1.db1.DBO.Table1 CD
join Table2 USRI on USRI.col00 = CD.col00
join table3 SR on USRI.col00 = SR.col00
Here, I'm trying to tun this from an instance and do a remote update. col00 is a primary key and there is a clustered index that exists on this column. When I run this query, it does a 'select * from tabl1' on the remote server and that table has about 60 million rows. I don't understand why it would do a select *... Also, we migrated to SQL 2005 a week or so back but before that everything was running smooth. I dont have the execution plan from before but this statement was fast. Right now, I can't run this statement at all. It takes about 37 secs to do one update. But if I did the update on a local server doing remote joins here, it would work fine. When I tried to show the execution plan, it took about 10 mins to show up an estimated plan and 99% of the time was spent on Remote scan. Please let me know what I can do to improve my situation. Thank you

The query below runs in sub second time if I don't call it as a stored procedure. I have looked at the execution plan for both the query and the query as a stored procedure and they are the same.
When I put the query into a stored procedure it takes over 2 minutes to run.
All feedback (even the ugly stuff) is more than welcome. I want to master this issue and forever put it behind me.
This is the sql when I just execute it outright:1 DECLARE

I have an SSIS package that when run from Visual Studio takes 1 minute or less to complete. When I schedule this package to run as a SQL Server job it takes 5+ and sometimes hangs complaining about buffers.
The server is a 4 way 3ghz Xeon (dual core) with 8GB ram and this was the only package running.
When I look in the log I see that the package is running and processing data, although very very very very very slowly.
Has anyone else experienced this?
Thanks for your help

Hello
I have interesting situation with one of my update statement.
Update takes 2 min to run and usually updates 20000 rows.
However lately update executes for longest time - 10 hours.
After I reindex table the updates run fine again
Please advice what can cause this
I do not think reindexing table before every update is good idea
We are running SQL 2000 SP4, Windows 2003 Server
Thank you in advance for all your help

I have a job scheduled that imports a table from a Oracle database. The job runs at 3am and reports success. But for some reason when i query the table to see how many records there are, I see the same row count as the day before (it should increase everyday- student enrollment). When i execute the package manually, the table updates fine.
SQL Server 2014/Win7 x64.

Problem Summary: Merge Statement takes several times longer to execute than equivalent Update, Insert and Delete as separate statements. Why?
I have a relatively large table (about 35,000,000 records, approximately 13 GB uncompressed and 4 GB with page compression - including indexes). A MERGE statement pretty consistently takes two or three minutes to perform an update, insert and delete. At one extreme, updating 82 (yes 82) records took 1 minute, 45 seconds. At the other extreme, updating 100,000 records took about five minutes.When I changed the MERGE to the equivalent separate UPDATE, INSERT & DELETE statements (embedded in an explicit transaction) the entire update took only 17 seconds. The query plans for the separate UPDATE, INSERT & DELETE statements look very similar to the query plan for the combined MERGE. However, all the row count estimates for the MERGE statement are way off.
Obviously, I am going to use the separate UPDATE, INSERT & DELETE statements. The actual query plans for the four statements ( combined MERGE and the separate UPDATE, INSERT & DELETE ) are attached. SQL Code to create the source and target tables and the actual queries themselves are below. I've also included the statistics created by my test run. Nothing else was running on the server when I ran the test.
Server Configuration:
SQL Server 2008 R2 SP1, Enterprise Edition
3 x Quad-Core Xeon Processor
Max Degree of Parallelism = 8
148 GB RAM
SQL Code:
Target Table:
USE TPS;
IF OBJECT_ID('dbo.ParticipantResponse') IS NOT NULL
DROP TABLE dbo.ParticipantResponse;
[code]....

Sorry i think i may have posted this in the incorrect forum before - if i have done it again here can someone tell me where i should post this please, thanks:
Hi,
we are having problems with a server Intel RZeon 3ghz, 3gb ram running 2003 service pack 2 with a 70gb drive and and 400 gb drive all with adequate free space. There are 6 hard disks in total and i assume operating at least RAID 5. We have SQL2000 server with a few standard sized databases and a connection to one other server.
A few months ago the back up of SQL server databases started taking 4- 5 hours when before it took 20 minutes. We had actually lost one of our disks in the RAID array and it before this was spotted by our engineers we reindexed the sql databases and defragged both 70gbC: and D: 400gb drives hoping to correct this slow down. Unfortunately the new disk had not been correctly seated and this was why it was taking 4-5 hours. After fixing the disk the backups took 12 minutes again but then started taking 2-3 hours after a few days.
The reindex/defrag did seem to improve the speed of the backups to 12 minutes (from 20 minutes) when the backup did function correctly (also the sql databases' performance improved). However the backups only take 12 minutes after a server reboot - this can last from only 2, up to 5 backups(days) in a row before a slow down to 2-3 hours and again only a reboot will sort out this problem.
NB this intermittent slowdown only occurred after the disk failure.
We have tried monitoring SQL server and can find no CPU/RAM intensive clashes or long running jobs interferring with the back up. Does anyone know what might be going on here? and if there are any server monitoring tools that may help us discover what is causing this problem ?
thanks for your help
best regards

I'm new to SQL and am having some trouble figuring out Triggers. We use Microsoft Dynamics SL (formerly Solomon) for our accounting. We have a table that only has data in it while we're processing checks called PRCHECKTRAN. We'd like to build a report that uses the information in this table but it's only available until we "keep" the checks that we're printing. This creates an added step because we have to stop our Payroll process to go out and print the reports. It's been suggested to use a trigger to make a copy of the records in the PRCHECKTRAN table so we've got them after the checks are "kept." We're wanting something that's done behind the scenes so the user can continue to do things the way they always have while giving us access to the data past the payroll period.
Basically as soon as we calculate checks, PRCHECKTRAN is populated. Once the checks are accepted as good, PRCHECKTRAN is cleaned out. I think I need an update or insert trigger that copies all records over to another table that we'll create called something like PRCHECKTRAN_HOLD. I'm just not familiar enough with SQL to write it. Any direction you can provide would be greatly appreciated. Thanks.

We have a MS SQL Server 6.5 database table with 643,000 records.
There are several indexes including some clustered indexes.
We do a statement: update wo set udf3 = '1234567890123456' where woid = '123'
this returns immediately.
Then we try the same statement where the string is 1 character longer and it
takes 45 minutes to return. There is no indication of what the server is doing
during this time.
There is no index on UDF3 and WOID is the primary key.
Any suggestions what is happening? What can we do to correct it?
DBCC CheckTable finds no errors.
name rows reserved data index_size unused

Hi There,I have an update statement to update a field of a table (~15,000,000records). It took me around 3 hours to finish 2 weeks ago.

I'm having a problem with an update operation in a stored procedure. Itruns so slowly that it is unusable, unless I comment a part out in whichcase it is very fast. However, I need the whole thing :). I have atable of email addresses of people who want to get invited to parties.Each row contains information like email address, city, state, country,and preferences for what types of events are of interest.The primary key is an EMAILID, and has a unique constraint on the emailfield. The stored procedure receives the field data as arguments, andinserts the record if the email address passed is not in the database.This works perfectly. However, if the stored procedure is called for anemail address that already exists, it updates the existing row insteadof doing an insert. This way I can build a web page that lets peoplemodify their preferences, opt in and out of the list and so on.If I am doing an update, the stored procedure runs SUPER SLOW (and thepage times out) unless I comment out the part of the update statementfor city, state, country and zipcode. However, I really need to be ableto update this!My database has 29 million rows.Thank you for telling me anything about how I can speed up this update!Here is the SQL statement to run the stored procedure:declare @now datetime;set @now = GetUTCDate();EXEC usp_EMAIL_Subscribe @Email='dberman@sen.us', @OptOutDate=@now,@Opt_GenInterest=1, @Opt_DatePeople=0, @Opt_NewFriends=1,@Opt_OldFriends=0, @Opt_Business=1, @Opt_Couples=0, @OptOut=0,@Opt_Events=0, @City='Boston', @State='MA', @ZCode='02215',@Country='United States'Here is the stored procedure:SET QUOTED_IDENTIFIER ONGOSET ANSI_NULLS ONGOALTER PROCEDURE [usp_EMAIL_Subscribe](@Email [varchar](50),@Opt_GenInterest [tinyint],@Opt_DatePeople [tinyint],@Opt_NewFriends [tinyint],@Opt_OldFriends [tinyint],@Opt_Business [tinyint],@Opt_Couples [tinyint],@OptOut [tinyint],@OptOutDate datetime,@Opt_Events [tinyint],@City [varchar](30), @State [varchar](20), @ZCode [varchar](10),@Country [varchar](20))ASBEGINdeclare @EmailID intset @EmailID = NULL-- Get the EmailID matching the provided email addressset @EmailID = (select EmailID from v_SENWEB_EMAIL_SUBSCRIBERS whereEmailAddress = @Email)-- If the address is new, insert the address and settings.

I have a SQL 2005 & SQL 2000 server. I am attempting to execute a simple update statement, something that looks like:
update AD
set AD.SomeDate = getdate()
from [ServerX].DB.dbo.Table
where ColumnX = 'X'
ServerX is the SQL 2000 box.
ServerY is the SQL 2005 box. Server Y is where this statement is invoked from. (Not shown in statement).
I have a linked server set up.
When executed from the 2000 box, it runs in < 1 second.
When both environments are 2005 to 2005, it takes less than < 1 second.

Hi to everyone,
I'm facing a problem that drives me crazy. I've a web application that has the following problem. When I test the application on my developement machine all runs fine, but when I put into production server there is a problem in connection pooling. Look at the following image, the blue line is the number of connection in the pool and the violet line is the number of connection reclaimed. From the image it is clear that connection are returned on the pool only in block, maybe when the garbage collection pass and reclaim the object. The strange thing is that on my developement machine all is good, and also I'm using Enterprise Library and the connection are managed internally.- Thanks to everyone for any help.

Hi!
Please
I got the following Error Message when trying to update a AS400 Database
"(Table Name) on (Data Source) not valid for operation"
My question is? Does Sql Server require journaling the files? How Should I change this option?. Please Help!
I did try to fix the above error, but then I got a new message:
OLE DB provider 'MSDASQL' supplied inconsistent metadata. The object '(user generated expression)' was missing expected column 'Bmk1000'.
Could you help me?
I will appreciate your help.
Thanks in advance

Does Anyone know what this means?
I run the query in the attached file on multiple servers with success but some of them refuse to cooperate. I've tried recreating the linked server on the problem servers but this doesn't help. All I want to do is check db file size and free space and get it to work. Why does it have to be so damn complicated?
Any ideas welcome - including an entirely different way of doing this.

I am getting an error trying to update a table in DB2 via SQL Server using a Linked Server. I can query the table using OPENQUERY but not via four-part name.
I can do this...
SELECT
Select * from OpenQuery(db2link, 'Select frst_nm from yccfssc9.person where id_prsn = 2')
When I try to Query using four-part names I get the following error...
7399 OLE DB Provider 'MSDASQL' reported an error. The provider does not support the necessary method.
UPDATE
When I try to update using this...
Update OpenQuery(db2link, 'Select frst_nm from yccfssc9.person where id_prsn=2') Set frst_nm = 'Fred'
I get the following error...
The OLE DB provider 'MSDASQL' indicates that the object has no columns.
When I try to update using four part names I get the error that says that the provider does not support the necessary method.
OTHER INFO
I was originially using version 6.1 of the db2 client (db2odbc.dll) but tried the 7.1 client and got the same error.
I believe we are using version 6.1 of db2 connect.
The mainframe db2 is version 7.0 release 1.0
Any help would be greatly appreciated. I referenced Microsoft Knowledge Base Article #270119 to get the workarounds that I attempted...

I have a linked server set up on my local SQL 2000 instance. I try and run an update against an SQL 2005 database and it take 29 seconds. I checked the execution plan and it says it takes the entire time on the Remote Scan. Is there something I need to do to speed this up? There is an index on the PK that I am searching against.

I've got the output from a cursor that generates the following sql statement.
Update SERVERNAME.DATABASENAME.dbo.TABLENAME set [update] = 'Y', status = NULL, completed = NULL where trigger_id = 10255
The statement generates the following error if the statement is run remotely
Msg 8180, Level 16, State 1, Line 1
Statement(s) could not be prepared.
Msg 156, Level 15, State 1, Line 1
Incorrect syntax near the keyword 'update'.
But the statement executes without error as formatted if run directly on the linked server.
Both servers are running 2000 sp 3a. The servers will be converted to 2005/2008 without patching to sp4.

Hi guys -
I have been googling all day and not found a reasonable solution to my problem.
Here is what I am trying to do. The T-SQL code is included at the bottom of this message.
- The user can specify columns that are stored in a CVColumn table (the data for which comes from an external source). For example, we may provide LastName and FirstName columns and the user could add ShoeSize and FavoriteColor.
- When we get the data from the other source, we create it as a dataset in the *code* with each user-defined field as a column of the table and each person as a row in the table. This is used *everywhere* including binding to grids, etc... So the dataset may look like this:
PersonID
LastName
FirstName
ShoeSize
FavoriteColor
- The dba has required that the data be stored in a normalized fashion. Since we don't know what the columns are - the data is stored in the *table* as:
PersonID
ColumnName
ColumnValue
- When the user gets the data from the external source the first time, the code loops through every person row and every column of the row to insert fields into the table using an Insert stored proc. This performs reasonable well.
- When the code retrieves the data from the database, it needs to reformat the data into one row per person, one column per field so that all of the other code can do the binding, etc.
- So I created a temp table with the appropriate rows and columns and then updated that table with the appropriate data. *This* is the stored proc that has been running now for almost an hour.
- There *must* be a way to do this that performs better?
Here is my T-SQL:
Code Snippet
DECLARE @columnNamesWithSizes varchar(8000)
DECLARE @delim varchar(1)
DECLARE @values varchar(8000)
-- Get the set of column names
SET @columnNamesWithSizes='swiCMKey VARCHAR(4092), swiCMContactManager VarChar(100), swiCMContactManagerID int,
swiCMFolder VarChar(4092), swiCMCVFolder VarChar(4092)'
SELECT @columnNamesWithSizes=COALESCE(@columnNamesWithSizes + ',', '') + ColumnName + ' VARCHAR(50)' FROM CVColumn
-- Create the table with the desired set of columns
EXEC ('CREATE TABLE ##tempTable ( ' + @columnNamesWithSizes + ')')
-- Insert the primary key into each row
EXEC ('INSERT INTO ##tempTable (swiCMKey) SELECT DISTINCT ContactID as swiCMKey FROM CVContact')
-- Use a cursor to loop through all of the records
SET @delim=''''
DECLARE @swiCMKey VARCHAR(4096)
DECLARE contactList CURSOR FOR
SELECT swiCMKey FROM ##tempTable
OPEN contactList
FETCH NEXT FROM contactList INTO @swiCMKey
-- Loop until all rows in temp table have been processed.
WHILE @@FETCH_STATUS = 0
BEGIN
SET @values=null
-- Retrieve all of the columns for this contact
SELECT @values = COALESCE(@values + ',', '') + ColumnName + '=' + @delim + COALESCE(Value,'') + @delim
FROM CVContact
WHERE CVContact.ContactID=@swiCMKey
-- Perform the update to the temp table with the column values
EXEC ('UPDATE ##tempTable SET ' + @values + ' WHERE swiCMKey=' + @delim + @swiCMKey + @delim)
-- Get the next one
FETCH NEXT FROM contactList INTO @swiCMKey
END
CLOSE contactList
DEALLOCATE contactList
-- Return the results
SELECT * from ##tempTable
-- Kill the temp table
DROP TABLE ##tempTable
Any ideas or othre suggestions would be much appreciated!
(BTW - up until today the data from the code-based dataset was stored as XML and then read back as XML. However, we found with 80,000+ people that it took 5 minutes to read the XML. But that is faster than this stored proc!<G>)

I have an IS package containing approx. 10 tasks in the control flow - one of these tasks is a rather large data flow containing around 50 transformations plus 3 sources and two destinations. Around 10 of these are script components and another 10 are Union All transformations. The rest are primarily lookups, conditional splits and derived column transformation.
The XML file containing the package is approx. 4.5 MB. As I am developing the package, it is becoming increasingly slow to work with as more transformations are added to the data flow. Now, it takes 8 minutes every time I have to open the package for development (DelayValidation is even set to true) and DTExec (not the debugger) uses the same amount of time before it starts executing the package. It also takes a very long time to edit the data flow, as I typically have to wait 1-2 minutes every time the designer has to "commit" a change.
Does anyone have any idea what can be done to speed up the package - both with regard to development and execution?

We are having problems getting the ADO.NET client to failover in a timely manner in a web application. Here's what happens:
1) Database fails over in 3 to 5 seconds
2) Clients attempt to login to primary and receive SQL server not available errors
3) The clients slowly start to connect and succeed without errorson the secondary.
4) We are still see SQL Server login errors on the primary, even after the failover
5) When we failback to the primary, it all happens within a few seconds (no problems)
If we recycle IIS, this problem goes away
Here's what we have tried
1) Turning off connection pooling (has no effect). We also can see the connections get killed on the primary server
2) Applying this hotfix (http://support.microsoft.com/kb/944099)
And yes, we are running a script to sync up the SIDS so that doesn't appear to be a problem. What seems to be happening is the primary server is getting stuck in the ADO.NET application memory. The problem is we don't know how to fix it.
BTW, our hardware is SQL Server 2005, Windows Server 2003, .NET 2.0 (and .NET 3.5)
Let me know if you need additional information. Thanks in advance

In an ASP, I have a dynamically created SQL statement that amounts to "SELECT * FROM Server1.myDB.dbo.myTable WHERE Col1 = 1" (Col1 is the table's primary key). It returns the data immediately when executed.
However, when the same record is updated with "UPDATE Server1.myDB.dbo.myTable SET Comments = 'blah blah blah' WHERE Col1 = 1", the page times out before the query can complete.
I watched the program in Profiler, and I saw on the update that sp_cursorfetch was being executed as an RPC once per each row in the table. In a table of 78000 records, the timeout occurs well before the last record is fetched, and the update bombs.
I can run the same statements in Query Analyzer from a linked server and have the same results. The execution plan shows that a Remote Query is occurring on the select that returns 1 row, and a Remote Scan is taking place on the update scanning 78000 rows (I guess this is where all the sp_cursorfetch calls are happening...?).
How can I prevent the Remote Scan? How can I prevent the execution of the RPC sp_cursorfetch for each row in the remote table?
Thank you!
