Remote Update Having A Linked Server Takes Forever To Execute
Oct 17, 2006
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

I used a stored procedure in my report. If I run the sp in Management Studio (on my pc, database is on a sql server) it takes only several minutes; but from reporting services (also on pc) I put it in the data tab and execute it, it takes forever, actually never finish. I want to know why it's taking so long to execute it from reporting services while it returns data instantly from Mgt Studio. There is cursor in the sp. I don't know whether this is the culprit. Anyone knows why? Thanks!
Below is the sp.

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

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.

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.

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;

SQL Server 2000, QA Database: A table called Telephone_Directory with just 4.000 records.
SELECT * FROM Telephone_Directory is taking forever.
If I stop the select after 1 second I see 162 rows.
If I stop the select after 1 minute I see again 162 rows.
Why this could be happening?
The same querie on Production Database is taking 6 seconds to retrieve the 4.000 records.

I have a database that is about 300 gig. I am setting up replication to a reporting server. We are doing a series or mock loads and I will need drop the tables and reload the main database a few times before we go live. To do that I plan to stop replication and drop all the articles, drop the subscription, then load the new data, then reinitialize and restart replication.
The first time I tried to do this, when I drop the articles, it seems to be trying to "clean up" the distribution database on the reporting server and that is taking a couple of hours to do. The disruption database is about 40 gig.
Is this correct behavior in SQL2005 replication? Is there a way to avoid this? I have all the replication pieces scripted out and would like to just drop replication, reload, and then run my scripts to recreate replication. But this "clean up" is going to cause me a lot of headache if I don't figure out what is going on.
Am I going down the wrong road here? Is there an easier way to do this? Any comments would be great!!!!
Thanks in advance for any help.

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!

I have a row that is being used log track plays on our website.
Here's the table:
CREATE TABLE [dbo].[Music_BandTrackPlays](
[ListenDate] [datetime] NOT NULL DEFAULT (getdate()),
[TrackId] [int] NOT NULL,
[IPAddress] [varchar](20)
) ON [PRIMARY]
There's a CLUSTERED INDEX on ListenDate ASC and a NON CLUSTERED INDEX on the TrackId.
I have a TRIGGER on the Music_BandTrackPlays table that looks like the following:
CREATE TRIGGER [trig_Increment_Music_BandTrackPlays_PlayCount]
ON [dbo].[Music_BandTrackPlays] AFTER INSERT
AS
UPDATE
Music_BandTracks
SET
Music_BandTracks.PlayCount = Music_BandTracks.PlayCount + TP.PlayCount
FROM
(SELECT TrackId, COUNT(*) AS PlayCount
FROM inserted
GROUP BY TrackId) AS TP
WHERE
Music_BandTracks.TrackId = TP.TrackId
When a simple INSERT statement is done on the Music_BandTrackPlays table, it can take quite a long time. When I remove the TRIGGER the INSERTs are immediate. The Execution plan for the TRIGGER shows that a 'Inserted Scan' is taking up most of the resources.
How exactly is the pseudo 'inserted' table formed?
For now, I think the easiest thing to do is update my logging page so it performs 2 queries. One to UPDATE the Music_BandTracks table and increment the counter, and perform the INSERT into the Music_BandTrackPlays table seperately.
I'm ok with that solution but I would really like to understand why the TRIGGER is taking so long. The 'inserted' pseudo table will be 1 row 99% of the time. Does SQL Server perform a table scan on all 20 million rows in order to determine what's new and put it in the inserted pseudo table?
Thanks!

I am trying to create a clustered index on a View of a table that has an xml datatype. This indexing ran for two days and still did not complete. I tried to leave it running while continuing to use the database, but the SELECT statements where executing too slowly and the DML statements where Timing out.

How can I make indexing the view with the xml data type take less time?

I have a simple update/initialization query (set integer column = 0 on all rows) that's been running for over 28 hours. There are just over 27 million rows in the table. In current activity it shows that the transaction is open but it's sleeping, and in locks it shows 1 DB S mode lock, 766 page X mode locks, 1 page U mode lock, and one table X mode lock. Server is 7.0 with 1.7 gig ram. Anyone have any ideas as to why it's taking so long? Table is about 7 gig in size; can't get to it in Enterprise Manager without locking it up...

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 need to be able to query remote server tables and join them to local tables. Thought that linked server would be best so that I can use local stored procs for parameters if needed. I have no administrative control over remote server. I have been given select permissions only to one db on remote server. Both servers are sql2000, local machine has spk3.
I have established the remote server in network client utility. I can register the remote server in EM, look at tables. I can run select statements against the remote server in QA when I log in and specify that server. I can reference an odbc data connection with web pages and display rowsets.
Next, I created a linked server under security, using sql (since it's an sql 2000 db) with the same name used above in the client utility and the em. I created a local login with the same name and password as the login used successfully above (Paragraph 2). On the security tab, I've used sa as the local login and entered the remote user and password, using the default 'be made without using a security context'. When I try to view the tables (which I can do through registered) or run this through QA:
SELECT * FROM OPENQUERY(CASCE, 'SELECT person_pk, lastname FROM dbName.dbo.tblName (NOLOCK)'),
I get: sql error 17: sql server does not exist or access denied
If I edit security, wipe out the top settings and specify the security context below using the login information, same thing. Tried messing around with different security contexts, no help or ole db error.
Any help? In addition, any tutorials out there a little more user friendly than the bol? I think I want to use the linked server option and stored procs.

exec [CIMPDB01CIMT2].zz_am.dbo.usp_SpaceMon
and so on..... no problem
But when I try to execute it by using a script (and substitute the instance names with values taken from a table) it won’t:
declare @x int
declare @dbname varchar(500)
declare @SQL nvarchar(600)
set @x = 1
create table #databases
(ID int IDENTITY,name varchar(500))
insert #databases select instancelongname from instances where actief='J'
while @x <= (select max(id) from #databases)
begin
select @dbname = name from #databases where id = @x
print @dbname
select @SQL='exec ' + @dbname + '.zz_am.dbo.usp_SpaceMon'
print @SQL
execute @SQL
set @x = @x + 1
end
drop table #databases
Msg 203, Level 16, State 2, Line 17
The name 'exec [CIMPDB01CIM].zz_am.dbo.usp_SpaceMon' is not a valid identifier.
Please help....

I setup a linked server with the following server login mapping:
Local login: db1reader
Remote login: db2reader
db2reader is granted to have read permissions in db2.
I created a stored proc p1 using WITH EXECUTE AS 'db1reader'
Inside the stored proc, I access the link server db2 by "select * from db2server.db2.dbo.table"
db1 reader is granted to have EXECUTE permission on stored proc p1. Trustworthy is on in db1.
Then, I use SQL server 2005 management studio to connect to db1 using db1reader account. Try to execute the stored proc p1. It tells me "Access to the remote server is denied because no login-mapping exists."
Then, I launched a new query in management studio, type in the following TSQL
execute as login = 'db1reader'
go
select * from db2server.db2.dbo.table
revert
go
This time, it works without any error.
Then, in the same query window. I delete all my old TSQL statements and execute my p1 stored proc again.
USE [db1]
GO
DECLARE @return_value int
EXEC @return_value = [dbo].[p1]
SELECT 'Return Value' = @return_value
GO
This time, it works.
What did I do wrong?

Can anyone tell me, if, generally, the performance or the cost of executing a pass-through command on a linked server in SQL Server 2005 would be better using OPENQUERY or the new option with EXECUTE -- whether the two servers are on the same box or not? I haven't been able to find a comparison between the two.
Have there been any tests of the difference?
What effect on performance is there with 'rpc out' set with sp_serveroption so EXECUTE can be used?
To be more specific I have a development box with SQL Server 2005 and Oracle 9.2.
The new option with EXECUTE would be something like the example in MSDN (Example J.) at:
http://msdn2.microsoft.com/en-us/library/ms188332.aspx
EXEC ( 'SELECT * FROM scott.emp') AT ORACLE;
GO

I have created a linked server (to an AS/400) via MSDASQL. It works fine when I execute queries locally (i.e. from Management Studio running on the SQL 2005 server).
However, when I execute a query from a remote machine I get an error (see below for the exact message).
I know the ODBC connection is between the SQL server and the AS/400, and that the remote client does not have connectivity to the AS/400. But shouldn't the SQL server be able to pass the query through to the linked server even if the query is initiated from a remote machine?
Does anyone have any suggestions on how I can resolve this problem so that queries against the linked server can be executed from remote machines?
Errors:
OLE DB provider "MSDASQL" for linked server "MERCURY" returned message "[Microsoft][ODBC Driver Manager] Driver's SQLSetConnectAttr failed".
OLE DB provider "MSDASQL" for linked server "MERCURY" returned message "[IBM][iSeries Access ODBC Driver]Key value in connection string too long.".
Msg 7303, Level 16, State 1, Line 1
Cannot initialize the data source object of OLE DB provider "MSDASQL" for linked server "MERCURY".
Environment: SQL 2005, Standard Edition SP2
Thanks in advance for any suggestions.

Hi,
Is that possible to execute SSIS packages from a remote SQL Server 2005 in another domain at local computer (Windows XP)?
Can I use SQL authentication to connect to the remote SSIS? My problem is, the user who execute the SSIS is not allow to access to SQL server directly. Is that possible to code everything in a batch file instead?
I tried to use web services to execute the remote SSIS but it always return "authentication error"?
Can someone help?
Many thanks!
Regards,
Mashmallow

The following T-SQL 2005 snippet executes a remote sproc on an Oracle database.
DECLARE @OutParam VARCHAR(5)
EXEC ('{Call getnextpin(1)}') AT ALTTEST
GetNextPin takes a single input parameter.
I need to modify the above code snippet to return the next PIN number into @OutParam.
Any ideas?
Any help appreciated.
Regards,
Paul.
