Runnaway UPDATE Statement In SQL2005 - How To Resolve?
Jun 16, 2006
I am in the process of moving a SQL2000 database to a SQL2005 database.
Porting from: SQL200, Windows Server 2000(SP4) (32 bit dual processor 4GB RAM)
to:SQL2005, Windows Server 2003(SP1) (x64 bit dual processor 4GB RAM)
After porting the database from SQL2000 to SQL2005 (no changes)
I then compare an update statement running from Management Studio on the 2003 Server and and Query analiser on the 2000
Server.
SQL2000 completes the command in 2 minutes SQL2005 is still running after 60 minutes.
SQL2000 is the live/production system with users connected, the SQL2005 is in a test environment with no other processors
running.
The SQL2005 activity monitor shows:
-----------------------------------
3 suspended processes in CXPACKET wait state and
2 runnable process high CPU counts (SQLServer running at 100% cpu).
All processes with the same Process ID.
Wait time is 0
High CPU counts for the runnable processes.
Low physical IO
No lock conflicts
When I add the "option (maxdop 1)" to the update statment then:
The activity monitor shows:
---------------------------
1 runnable process with a high CPU count (SQLServer running at 50% cpu).
Wait time is 0
High CPU count for the runnable processe.
Low physical IO
No lock conflicts
How do I debug this situation?
Why is the SQL2005 unable to complete the task?
The update statement is as follows...
-------------------------------------
update BI_LENDING_TRANSACTIONS
set [Balance Movement Month] = M.[Balance Movement Month]
from BI_LENDING_TRANSACTIONS as T,
BI_BALANCE_MOVEMENT_DATES as M,
BI_COMPANIES as C
where (T.[Transaction Date] >=
(SELECT DATEADD(d, - 70, minDate) from (select min([Transaction Date]) minDate
from p_BI_LENDING_TRANSACTIONS) t1)
OR
T.[Transaction Date] >= C.[MostRecentSnapShotDate] or
T.[Value Date] = T.[Balance Movement Month] ) and
T.[Value Date] <= C.[MostRecentSnapShotDate] and
T.[Value Date] >= T.[Transaction Date] and
T.[Company_Code] = M.[Company_Code] and
T.[Value Date] > M.[SnapShotFromDate] and
T.[Value Date] <= M.[SnapShotToDate] and
C.[Company_Code] = M.[Company_Code]
I am in the process of moving a SQL2000 database to a SQL2005 database.
Porting from: SQL200, Windows Server 2000(SP4) (32 bit dual processor) to:SQL2005, Windows Server 2003(SP1) (x64 bit dual processor)
After porting the database from SQL2000 to SQL2005 (no changes) running the same update statement from Management Studio on the 2003 Server and and Query analiser on the 2000 Server.
SQL2000 completes the command in 2 minutes SQL2005 is still running after 60 minutes.
SQL2000 is the live/production system with users connected, the SQL2005 is in a test environment with no other processors running.
When the problem first showed up the SQL2005 activity monitor displayed CXPACKET wait type on 2 processes with the same pid number. I now no longer have any wait type being displayed but my wait time is increasing rapidly. No block is reported.
I assume that I have an CXPACKET lock problem.
Am I correct that I have a CXPACKET problem and if so what is the resolution?
The update statement is as follows...
update BI_LENDING_TRANSACTIONS set [Balance Movement Month] = M.[Balance Movement Month] from BI_LENDING_TRANSACTIONS as T, BI_BALANCE_MOVEMENT_DATES as M, BI_COMPANIES as C where (T.[Transaction Date] >= (SELECT DATEADD(d, - 70, minDate) from (select min([Transaction Date]) minDate from p_BI_LENDING_TRANSACTIONS) t1) OR T.[Transaction Date] >= C.[MostRecentSnapShotDate] or T.[Value Date] = T.[Balance Movement Month] ) and T.[Value Date] <= C.[MostRecentSnapShotDate] and T.[Value Date] >= T.[Transaction Date] and T.[Company_Code] = M.[Company_Code] and T.[Value Date] > M.[SnapShotFromDate] and T.[Value Date] <= M.[SnapShotToDate] and C.[Company_Code] = M.[Company_Code]
I have a database table which needs to make the Index "ParentREF, UniqueName" unique - but this fails because duplicate keys are found. Thus I now need to cleanup these duplicate rows - but I cannot just delete the duplicates, because they might have rows in detail tables. This means that all duplicate rows needs an update on the "UniqueName" value - but not the first (valid) one!
I can find those rows by
SELECT OID, UniqueName, ParentREF, CreatedUTC, ModifiedUTC FROM dbo.CmsContent AS table0 WHERE EXISTS ( SELECT OID, UniqueName, ParentREF FROM dbo.CmsContent AS table1 WHERE table0.ParentREF = table1.ParentREF AND table0.UniqueName = table1.UniqueName AND table0.OID != table1.OID ) ORDER BY ParentREF, UniqueName, ModifiedUTC desc
...but I struggle to make the required SQL (SP?) to update the "invalid" rows. Note: the "valid" row is the one with the newest ModifiedUTC value - this row must kept unchanged!
ATM the preferred (cause easiest) way is to rename the invalid rows with UniqueName = OID because if I use any other name I risk to create another double entry.
SQL2000 used to send a 2 part update using sp_msdel followed by sp_msins instead of just calling sp_msupd. I thought this used to happen on tables with compostie primary keys. Does any know know if this still occurs in SQL2005 and maybe why?
On 1 pc i installed VS2008 besides VS2005 and SQL 2005 (before i installed VS2008 everything was fine)
On the other is a fresh installed XP machine with only VS2008 SQL2550 and Office2007 Latets service packs are installed
On both machines when i open a table in SQL 2005 with the 'open table' command the show of the table is very slow. Every row is updated file by field, the grid is not showing, the row and column headers are not 'grey' as normal.
Scrollign is impossible as the screen updates start again that slow.
Even a small table with 10 rows and 15 field behaves this slow. Its not workable.
When i run above script, it prompt me an error message; "Microsoft OLE DB Provider for SQL Server The requested operation could not be performed because OLE DB provider "IBMDA400" for linked server "TESTDB2" does not support the required transaction interface."
If i run it without "begintrans" and "committrans", it update the data successfully.
I am currently having this problem with gridview and detailview. When I drag either onto the page and set my select statement to pick from one table and then update that data through the gridview (lets say), the update works perfectly. My problem is that the table I am pulling data from is mainly foreign keys. So in order to hide the number values of the foreign keys, I select the string value columns from the tables that contain the primary keys. I then use INNER JOIN in my SELECT so that I only get the data that pertains to the user I am looking to list and edit. I run the "test query" and everything I need shows up as I want it. I then go back to the gridview and change the fields which are foreign keys to templates. When I edit the templates I bind the field that contains the string value of the given foreign key to the template. This works great, because now the user will see string representation instead of the ID numbers that coinside with the string value. So I run my webpage and everything show up as I want it to, all the data is correct and I get no errors. I then click edit (as I have checked the "enable editing" box) and the gridview changes to edit mode. I make my changes and then select "update." When the page refreshes, and the gridview returns, the data is not updated and the original data is shown. I am sorry for so much typing, but I want to be as clear as possible with what I am doing. The only thing I can see being the issue is that when I setup my SELECT and FROM to contain fields from multiple tables, the UPDATE then does not work. When I remove all of my JOIN's and go back to foreign keys and one table the update works again. Below is what I have for my SQL statements:------------------------------------------------------------------------------------------------------------------------------------- SELECT:SELECT People.FirstName, People.LastName, People.FullName, People.PropertyID, People.InviteTypeID, People.RSVP, People.Wheelchair, Property.[House/Day Hab], InviteType.InviteTypeName FROM (InviteType INNER JOIN (Property INNER JOIN People ON Property.PropertyID = People.PropertyID) ON InviteType.InviteTypeID = People.InviteTypeID) WHERE (People.PersonID = ?)UPDATE:UPDATE [People] SET [FirstName] = ?, [LastName] = ?, [FullName] = ?, [PropertyID] = ?, [InviteTypeID] = ?, [RSVP] = ?, [Wheelchair] = ? WHERE [PersonID] = ? ---------------------------------------------------------------------------------------------------------------------------------------The only fields I want to update are in [People]. My WHERE is based on a control that I use to select a person from a drop down list. If I run the test query for the update while setting up my data source the query will update the record in the database. It is when I try to make the update from the gridview that the data is not changed. If anything is not clear please let me know and I will clarify as much as I can. This is my first project using ASP and working with databases so I am completely learning as I go. I took some database courses in college but I have never interacted with them with a web based front end. Any help will be greatly appreciated.Thank you in advance for any time, help, and/or advice you can give.Brian
Following update runs 20 hours till TEMPDB grows up to 400GB and runs out of space with error message:

Ok I have a query "SELECT ColumnNames FROM tbl1" let's say the values returned are "age,sex,race".
Now I want to be able to create an "update" statement like "UPATE tbl2 SET Col2 = age + sex + race" dynamically and execute this UPDATE statement. So, if the next select statement returns "age, sex, race, gender" then the script should create "UPDATE tbl2 SET Col2 = age + sex + race + gender" and execute it.
i was tasked to created an UPDATE statement for 6 tables , i would like to update 4 columns within the 6 tables , they all contains the same column names. the table gets its information from the source table, however the data that is transferd to the 6 tables are sometimes incorrect , i need to write a UPDATE statement that will automatically correct the data. the Update statement should also contact a where clause
the columns are [No] , [Salesperson Code], [Country Code] and [Country Name]
i was thinking of doing
Update [tablename] SET [No] = CASE WHEN [No] ='AF01' THEN 'Country Code' = 'ZA7' AND 'Country Name' = 'South Africa' ELSE 'Null' END
Hello,I am trying to update records in my database from excel data using vbaeditor within excel.In order to launch a query, I use SQL langage in ADO as follwing:------------------------------------------------------------Dim adoConn As ADODB.ConnectionDim adoRs As ADODB.RecordsetDim sConn As StringDim sSql As StringDim sOutput As StringsConn = "DSN=MS Access Database;" & _"DBQ=MyDatabasePath;" & _"DefaultDir=MyPathDirectory;" & _"DriverId=25;FIL=MS Access;MaxBufferSize=2048;PageTimeout=5;" &_"PWD=xxxxxx;UID=admin;"ID, A, B C.. are my table fieldssSql = "SELECT ID, `A`, B, `C being a date`, D, E, `F`, `H`, I, J,`K`, L" & _" FROM MyTblName" & _" WHERE (`A`='MyA')" & _" AND (`C`>{ts '" & Format(Date, "yyyy-mm-dd hh:mm:ss") & "'})"& _" ORDER BY `C` DESC"Set adoConn = New ADODB.ConnectionadoConn.Open sConnSet adoRs = New ADODB.RecordsetadoRs.Open Source:=sSql, _ActiveConnection:=adoConnadoRs.MoveFirstSheets("Sheet1").Range("a2").CopyFromRecordset adoRsSet adoRs = NothingSet adoConn = Nothing---------------------------------------------------------------Does Anyone know How I can use the UPDATE, DELETE INSERT SQL statementsin this environement? Copying SQL statements from access does not workas I would have to reference Access Object in my project which I do notwant if I can avoid. Ideally I would like to use only ADO system andSQL approach.Thank you very muchNono
It appears to update only the first qualifying row. The trace shows a row count of one when there are multiple qualifying rows in the table. This problem does not exist in JDBC 2000.
I'm writing a fairly involved stored procedure. In this Stored Procedure, I have an update statement, followed by a select statement. The results of the select statement should be effected by the previous update statement, but its not. When the stored procedure is finish, the update statement seemed to have worked though, so it is working.
I suspect I need something, like a GO statement, but that doesnt seem to work for a stored procedure. Can anyone offer some assistance?
I run the following statement and it will not update beyond 7 million plus rows and I have about 38 million to complete. I keep checking updated row counts and after 1/2 day it's still the same so I know something is wrong because it was rolling through no problem when I initiated it. I need to complete ASAP so it's adding to my frustration. The 'Acct_Num_CH' field is an encrypted field (fyi).
SET rowcount 10000 UPDATE [dbo].[CC_Info_T] SET [Acct_Num_CH] = 'ayIWt6C8sgimC6t61EJ9d8BB3+bfIZ8v' WHERE [Acct_Num_CH] IS NOT NULL WHILE @@ROWCOUNT > 0 BEGIN SET rowcount 10000 UPDATE [dbo].[CC_Info_T] SET [Acct_Num_CH] = 'ayIWt6C8sgimC6t61EJ9d8BB3+bfIZ8v' WHERE [Acct_Num_CH] IS NOT NULL END SET rowcount 0
I just upgraded my SQL 2000 server to SQL2005. I forked out all that money, and now it takes 4~5 seconds for a webpage to load. You can see for yourself. It's pathetic. When I ran SQL2000, i was getting instant results on any webpage. I can't find any tool to optimize the tables or databases. And when I used caused SQL Server to use 100% cpu and 500+MB of ram. I can't have this.Can anyone give me some tips as to why SQL 2005 is so slow?

i've a SQL2000 server and SQLserver CE installed, also i've about 100 reps having a palm with them, entering a data through a developed software, then make a daily connection to make synchronization and send their data to the server. most of thes reps make the synchronization at the same time each day, so most of them get the error message of Deadlock on a resource of process ID... how can i resolve this issue and what is the most appropriate type of locking i can use to prevent this issue?

But when i type any word(e.g East) the page is refresh back to Webform1.aspx with the not updated data and the database is also not updated. Any idea?

I need some help. please. Here is what I got. From the webpage I can pull the following data to update a table. update Vehicle set Name='TestUnitName' ,Make='TestMake', Model='TestModel', SoftwareVersion='TestVersion', DynamicChange='1', ProviderID='1', Description='TestDescription', VIN='TestVIN', IMEI='TestSIM', EngineTypeId=' ', Phone=' ', MobilePhoneProviderID='' where VehicleID=64 But I also get the error: "The UPDATE statement conflicted with the FOREIGN KEY constraint "FK_Vehicle_EngineTypes".

I need to set a column value where the id is within a string. However, I need to set the column to a default value if the id is not within the string. Hope that was easy to understand!
ie:
This currently works...
SET @strSQL = 'UPDATE tblTest SET Archive = 1 WHERE RecID IN (' + @IDList + ')
If the ID is not in the list then I want that column set to 0. How can I do this?
Hi I use a update sub, the problem is that i got an error, the error is: Syntax error in UPDATE statement. I guess the UPDATE statement is: strUpdate = "Update tblUsers Set UserName=@UserName, Password=@Password, RetypePassword=@RetypePassword, Email=@Email, Comments=@Comments Where UserID=@UserID"
Remark:I use Acceess DataBase, exactly the same code works fine in SQL, i just changed the DataBase(From Access to SQL).
Is the problem can be in other place? Thank you very much for your assistance.
Hi, I'm having trouble writing this update statement and was wondering if anyone could help me out :
My database is sort of set up lilke this: There are 3 tables: Orders, OrderDetails and Inventory
Orders has a pk called OrderID. OD has several ProductIDs listed for that OrderID Inventory has 2 fields, the pk InventoryID(which is the same as ProductID) and QOH
So OD kinda looks like this: OrderID ProductID Quantity Cost 192 12 2 $10 192 3 1 $12 192 14 2 $50 193 12 1 $11 .... . ... ...
so what i want to do is take each productID for a specific orderid and decrement the inventory for it by OD.quantity
This is what I was trying
UPDATE Inventory Set QOH = QOH - @qty WHERE Inventory.InventoryID IN ( SELECT ProductID FROM OrderDetails WHERE OrderDetails.OrderID = @OrderID and @qty = OrderDetails.Quantity )
