Update Never Finishes. Update Utilizes Indexes And Usually Takes 2 Min To Run.
Feb 8, 2008
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

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.

I am cleaning up a large database table that has Date keys instead of real DateTimes. To do this, I am running the following query...
UPDATE MQIC.DBO.OBSERVATION_F
SET MQIC.DBO.OBSERVATION_F.OBS_DATE = MQIC.DBO.DATE_D.ACTUAL_DATE
FROM MQIC.DBO.OBSERVATION_F INNER JOIN MQIC.DBO.DATE_D
ON MQIC.DBO.OBSERVATION_F.DATE_KEY = MQIC.DBO.DATE_D.DATE_KEY
where Actual_Date is what is being stored, and the Date_Key is to be dropped.
The particulars are this -
Date_D table - 92,000 rows - 40 MB
Observation_F - 2,000,000 rows - 3.2 GB
This is being run on a remotedly hosted rack server with an AMD processor, 1 GB RAM, 60 GB harddisk space, 20 GB used.
SQL-Server 2005 Express - SP1
If I do the same query as a SELECT Statement,
UPDATE MQIC.DBO.OBSERVATION_F
SELECT MQIC.DBO.OBSERVATION_F.DATE_KEY, MQIC.DBO.DATE_D.ACTUAL_DATE
FROM MQIC.DBO.OBSERVATION_F INNER JOIN MQIC.DBO.DATE_D
ON MQIC.DBO.OBSERVATION_F.DATE_KEY = MQIC.DBO.DATE_D.DATE_KEY
it runs to completion in about 15 min - during the entire time there is extensive used of CPU from Task Manager.
If I do the above statement, it seems to use lots of resources (50% +) for about 5 min, then falls to 5%. It just seems to sit there, for an hour + at which time I've killed the query.
This is actually the second time I tried this. The first time was on a different machine, with the P4, 3GB RAM, plenty of disk space, and using SQL-Server 2005 Standard - SP1. Exactly the same decrease in resources happened, and even though it ran several hours, no results.
Any thoughts here - not waiting long enough, memory leaks, etc.?
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. After thatno one touched the server and no configuration changed. Untilyesterday, I re-ran it again and it took me more than 18hrs and stillnot yet finished!!!What's wrong with it? I can ran it successfully before. I have triedtwo times but the result was still the same.My SQL statement is:update [all_sales] aset a.accounting_month = b.accounting_monthfrom date_map bwhere a.sales_date >= b.start_date and a.sales_date < b.end_date;An index on [all_sales].sales_date is built successfully.A composite index on ([date_map].start_date, [date_map].end_date) isbuilt successfully.My server config is:SQL Server 2000 with Service Pack 3Windows 2000 with Service Pack 4DELL PowerEdge 6650 ServerDUAL XEON 1900MHz Processors2G RAM2G Page File on Drive C2G Page File on Drive DDELL Diagnostics on all SCSI harddisks were all PASSED.Any experts could simly give me a help????Thanks x 1,000,000,000

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.

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

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]....

I am using the Maintencance Plan wizard, but it only allows me to either select the "reorganize data and indexes" option or the "update statistics" option (in the Optimizations tab). I can't select both of them. What is the reason for this?

Hello again,
Two Short questions this time,
I have a table with several indexes, currently most of them are very narrow (one column), and the question is, when I modify the table by updating a record, does all the indexes are calculated again?? Even if the modified field isn't indexed??? Or the server is smart and knows what indexes to calculate if any.
Second question, can I give to a query a low priority(In dynamic SQL), for example when I don't want my query to exploit too many system resources so it won't interfere the main system ?
Inon.

We are planning to standardize our newly deployed sql server, As a part of it we have configured 2 maintenance plans 1) Update Statistics which runs daily and 2) Index Reorganize which runs on weekly.
Apart from above, any other things to be in place for better maintenance of the sql server.
Also, how to Index Rebuild activity for clustered indexes requires any downtime.

I am hoping someone can shed light on this odd behavior I am seeing running a simple UPDATE statement on a table in SQL Server 2000. I have 2 tables - call them Table1 and Table2 for now (among many) that need to have certain columns updated as part of a single transaction process. Each of the tables has many columns. I have purposely limited the target column for updating to only ONE of the columns in trying to isolate the issue. In one case the UPDATE runs fine against Table1... at runtime in code and as a manual query when run in QueryAnalyzer or in the Query window of SSManagementStudio - either way it works fine.
However, when I run the UPDATE statement against Table2 - at runtime I get rowsaffected = 0 which of course forces the code to throw an Exception (logically). When I take out the SQL stmt and run it manually in Query Analyzer, it runs BUT this is the output seen in the results pane...
(0 row(s) affected)
(1 row(s) affected)
How does on get 2 answers for one query like this...I have never seen such behavior and it is a real frustration ... makes no sense. There is only ONE row in the table that contains the key field passed in and it is the same key field value on the other table Table1 where the SQL returns only ONE message (the one you expect)
(1 row(s) affected)
If anyone has any ideas where to look next, I'd appreciate it.
Thanks

Hi SQL fans,I realized that I often encounter the same situation in a relationdatabase context, where I really don't know what to do. Here is anexample, where I have 2 tables as follow:__________________________________________ | PortfolioTitle|| Portfolio |+----------------------------------------++-----------------------------+ | tfolio_id (int)|| folio_id (int) |<<-PK----FK--| tfolio_idfolio (int)|| folio_name (varchar) | | tfolio_idtitle (int)|--FK----PK->>[ Titles]+-----------------------------+ | tfolio_weight(decimal(6,5)) |+-----------------------------------------+Note that I also have a "Titles" tables (hence the tfolio_idtitlelink).My problem is : When I update a portfolio, I must update all theassociated titles in it. That means that titles can be either removedfrom the portfolio (a folio does not support the title anymore), addedto it (a new title is supported by the folio) or simply updated (atitle stays in the portfolio, but has its weight changed)For example, if the portfolio #2 would contain :[ PortfolioTitle ]id | idFolio | idTitre | poids1 2 1 102 2 2 203 2 3 30and I must update the PortfolioTitle based on these values :idFolio | idTitre | poids2 2 202 3 352 4 40then I should1 ) remove the title #1 from the folio by deleting its entry in thePortfolioTitle table2 ) update the title #2 (weight from 30 to 35)3 ) add the title #4 to the folioFor now, the only way I've found to do this is delete all the entriesof the related folio (e.g.: DELETE TitrePortefeuille WHERE idFolio =2), and then insert new values for each entry based on the new givenvalues.Is there a way to better manage this by detecting which value has to beinserted/updated/deleted?And this applies to many situation :(If you need other examples, I can give you.thanks a lot!ibiza

If I have a table with 1 or more Nullable fields and I want to make sure that when an INSERT or UPDATE occurs and one or more of these fields are left to NULL either explicitly or implicitly is there I can set these to non-null values without interfering with the INSERT or UPDATE in as far as the other fields in the table?
EXAMPLE:
CREATE TABLE dbo.MYTABLE(
ID NUMERIC(18,0) IDENTITY(1,1) NOT NULL,
FirstName VARCHAR(50) NULL,
LastName VARCHAR(50) NULL,
[Code] ....
If an INSERT looks like any of the following what can I do to change the NULL being assigned to DateAdded to a real date, preferable the value of GetDate() at the time of the insert? I've heard of INSTEAD of Triggers but I'm not trying tto over rise the entire INSERT or update just the on (maybe 2) fields that are being left as null or explicitly set to null. The same would apply for any UPDATE where DateModified is not specified or explicitly set to NULL. I would want to change it so that DateModified is not null on any UPDATE.
INSERT INTO dbo.MYTABLE( FirstName, LastName, DateAdded)
VALUES('John','Smith',NULL)

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 having a strange problem that I can't figure out. I have an SQL stored procedure that updates a small database table. When testing the Stored Procedure from the Server Explorer, it works fine. However, when I run the C# code that's supposed to use it, the data doesn't get saved. The C# code seems to run correctly and the parameters that are passed to the SP seem to be okay. No exceptions are thrown.
The C# code:
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["touristsConnectionString"].ConnectionString);
SqlCommand cmd = new SqlCommand("fort_SaveRedirectURL", conn);
cmd.CommandType = CommandType.StoredProcedure;
Label accomIdLabel = (Label)DetailsView1.FindControl("lblID");
int accomId = Convert.ToInt32(accomIdLabel.Text);
cmd.Parameters.Add("@accomId", SqlDbType.Int).Value = accomId;
cmd.Parameters.Add("@path", SqlDbType.VarChar, 250).Value = GeneratePath();
try
{
conn.Open();
cmd.ExecuteNonQuery();
}
catch(Exception ex)
{
throw ex;
}
finally
{
conn.Close();
}
The Stored Procedure:
ALTER PROCEDURE developers.fort_SaveRedirectURL
(
@accomId int,
@path varchar(250)
)
AS
DECLARE
@enabled bit,
@oldpath varchar(250)
/* Ensure that the accommodation has been enabled */
SELECT @enabled = enabled FROM Experimental_Accommodation
WHERE Experimental_Accommodation.id = @accomId
IF (@enabled = 1)
BEGIN
/* Now check if a path already exists */
SELECT @oldpath = oldpath FROM Experimental_Adpages_Redirect
WHERE Experimental_Adpages_Redirect.accom_id = @accomId
IF @oldpath IS NULL
BEGIN
/* If Path already exists then we should keep the existing URL */
/* Otherwise, we need to insert a new one */
INSERT INTO Experimental_Adpages_Redirect
(oldpath, accom_id)
VALUES (@path,@accomId)
END
END
RETURN

I'm new to this forum.
This 'problem' has occured many times, but I've always found a way around it.
I have pages with datagrids, in which a user can edit a certain fields and then update the tables with new data. Lets say when a user edit a Name field and a money field. If he/she left those two fields blank, the table is automatically updated with a <null> (for the name field) and a 0 (for the money field.) Both these columns were set up to allow Null values.
Anyone has an idea why they were updated that way? And is there like a standard on how the data types are updated if a field is left blank?
Thank you very much.

I do realize that his could be posted in a few spots but I think the answer is in the SQL.
I have a ASP.NET page, with a SqlDataSource, Text Box and Calendar Controls. I have the textbox and calendar controls eval'ed to the same sql data source DateTime Field. The text box is formatted eval to small time and the calendars eval has no formatting.
ex:
<asp:TextBox ID="START_TIME" Text='<%# Eval("EVENT_START","{0:t}") %>' runat=server Width=200></asp:TextBox>
I want to merge the two controls; one has the date the other has the time when I update the pages data to the SqlDataSource field EVENT_START. I've tried a couple of methods, but I would like some other opinions. As Sql server only supports date and time together I am storing the two together.
I could merge the two together in the code behind on the update button's event handler or merge the two during the update query using parameters.
Not that I could get an illegal date for the calendar control, but I could get garbage from the textfield time. So I still would have to do validation on the text field before the SQL server could do the update.
There's a few ways to go about this, so I was wondering if anyone else has figured out an elegant way to handle it.

I want to update two tables in one page. So I created two FormView bound on two SqlDataSource controls, and I create a Update button on the bottom of page. And I writen some codes as below:
btnUpate_Click(object sender, EventArgs e){
sqlDataSource1.Update();
sqlDateSource2.Update();}
But, the records haven't updated.
In SqlDataSource2_Updating() function, I found all the parameters is null.
So, how to modify my code to do it.

hi!
I have a big problem. If anyone can help.
I want to retrieve the last update time of database. Whenever any update or delete or insert happend to my database i want to store and retrieve that time.
I know one way is that i have to make a table that will store the datetime field and system trigger / trigger that can update this field record whenever any update insert or deletion occur in database.
But i don't know exactly how to do the coding for this?
Is there any other way to do this?
can DBCC help to retrieve this info?
Please advise me how to do this.
Thanks in advance.

I have a table where table row gets updated multiple times(each column will be filled) based on telephone call in data.
Initially, I have implemented after insert trigger on ROW level thinking that the whole row is inserted into table will all column values at a time. But the issue is all columns are values are not filled at once, but observed that while telephone call in data, there are multiple updates to the row (i.e multiple updates in the sense - column data in row is updated step by step),
I thought to implement after update trigger , but when it comes to the performance will be decreased for each and every hit while row update.
I need to implement after update trigger that should be fired on column level instead of Row level to improve the performance?

Hello,
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?

Hi! Select gets all records that contains illegal chars... Ok, to replace '[' { and some other chars I will make AND '% .. %' and place other intervals, that is not the problem.The problem is: How to replace not allowed chars ( ! @ # $ % ^ & * ( ) etc. ) with '_' ?I have seen that there is a function REPLACE, but can't figure out how to use it. 1 SELECT user_username
2 FROM users
3 WHERE user_username LIKE '%[!-)]%';
