UPDATE Statement Speed Drop
May 5, 2003
Background:
I have a table (named achtransactions) that has 618,423 rows. I have the ID field set as the Primary Key.
Problem:
Usually when doing a single, simple update (ie: UPDATE achtransactions SET transstatus = 'APPROVED' where id = 123456) it would take less than a second.
All of a sudden, beginning today, the same UPDATE statement is taking about 20 seconds on average. Other smaller tables (~100 rows) update instantly, just appears to be this one table.
Any ideas on what I should look at to find the problem?
Thanks in advance,
CooperS

Hello,
Server hardware: Intel core 2 duo, 2Gb ram, SATA 1500Gb, SQL Server 2005
I have big table (~ from 50000 to 500000 rows) :
Code Snippet
CREATE TABLE [dbo].[CommonPointValues](
[ID] [bigint] IDENTITY(1,1) NOT NULL,
[pointID] [bigint] NOT NULL,
[pointValue] [numeric](10, 2) NOT NULL,
[qualityID] [int] NOT NULL,
[dateFrom] [datetime] NULL,
[dateTo] [datetime] NULL,
CONSTRAINT [PK_PointValues] PRIMARY KEY CLUSTERED
(
[ID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, FILLFACTOR = 100) ON [PRIMARY]
) ON [PRIMARY]
UPDATE statement:
Code SnippetUPDATE dbo.CommonPointValues SET dateTo = @last_update WHERE ID = @lastValID
2000 rows update takes about 1 sec.
INSERT statement:
Code Snippet
INSERT INTO dbo.CommonPointValues (pointID, pointValue, qualityID, dateFrom, dateTo )
VALUES (@point_id, @value_new, @quality_new, @last_update, @last_update )
Speed with INSERT is similar like with UPDATE.
I need about 10000 updates per 1 second and 10000 inserts per 1 second or together 5000 inserts and 5000 updates per 1 sec.
Should I update hardware or try some improvements to table structure.

I have a single UPDATE statement that has been running for 13+ hours and I have no idea of when it will complete.
Recipients has 80 million records
UpdatedStagingRecipients has 34 million records.
Why would this possibly take so long? Is there anything that I can do at all?
UPDATE Recipients
SET Recipients.First = UpdatedStagingRecipients.First
, Recipients.Last = UpdatedStagingRecipients.Last
, Recipients.StreetAddress = UpdatedStagingRecipients.StreetAddress
, Recipients.City = UpdatedStagingRecipients.City
, Recipients.State = UpdatedStagingRecipients.State
, Recipients.Postal = UpdatedStagingRecipients.Postal
, Recipients.Country = UpdatedStagingRecipients.Country
, Recipients.DOB = UpdatedStagingRecipients.DOB
, Recipients.Obscene = UpdatedStagingRecipients.Obscene
, Recipients.Gender = UpdatedStagingRecipients.Gender
, Recipients.IPv4 = UpdatedStagingRecipients.IPv4
, Recipients.NameSourceID = UpdatedStagingRecipients.NameSourceID
, Recipients.NameLine = UpdatedStagingRecipients.NameLine
, Recipients.AddressSourceID = UpdatedStagingRecipients.AddressSourceID
, Recipients.AddressLine = UpdatedStagingRecipients.AddressLine
, Recipients.RecordCreationSourceID = UpdatedStagingRecipients.RecordCreationSourceID
FROM Recipients INNER JOIN UpdatedStagingRecipients ON (Recipients.UserName = UpdatedStagingRecipients.UserName AND Recipients.DomainID = UpdatedStagingRecipients.DomainID)
TRUNCATE TABLE UpdatedStagingRecipients

The following stored procedure is run whenever someone searches my database. When I first created the site, this search took less than 3 seconds. Now, there is more data in the system and the search is taking over 30 seconds.
I am not very good with SQL and I'm sure I am doing some dumb things. Is there a better way to write this query to speed things up?
Thanks a lot,

We are planning to add a new attribute to one of our tables to speed updata access. Once the attribute is added, we will need to populatethat attribute for each of the records in the table.Since the table in question is very large, the update statement istaking a considerable amount of time. From reading through old postsand Books Online, it looks like one of the big things slowing down theupdate is writing to the transaction log.I have found mention to "truncate log on checkpoint" and using "SETROWCOUNT" to limit the number of rows updated at once. Or "dumptransaction databaseName with No_Log".Does anyone have any opinions on these tactics? Please let me know ifyou want more information about the situation in order to provide ananswer!

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.

Processor speed? or more Ram? I want to make a good decision, so I´d really appreciate your help...
Thanks, Luis Luevano

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

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
What is the best way to script this

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.

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?

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]

Hey all,
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?
Thanks in advance,
Pete

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
)
but, i'm having no luck...... any suggestions ?

what would the syntax be for the following update statement?
"UPDATE [Stocklist]
SET
[client] to textbox2.text
[notes] to textbox3.text
[paid] to textbox4.text
[status] to "old"
WHERE
[Make] = dropdownlist1.SelectedValue
[Model] = dropdownlist2.SelectedValue
[IMEI] = dropdownlist3.SelectedValue
[status] = new"
I know this is a simple question even for someone who is just starting out , thats why I posted it into the "Getting Started" forum.
Thanx in Advance

I have a table that looks like this.
tkinit adir adate1
0007 0.00 01/01/1996
0007 0.00 01/01/1997
0007 25.00 01/01/1998
0007 27.00 06/01/1998
0008 0.00 01/01/1996
0008 0.00 01/01/1997
0008 32.00 01/01/1998
0008 37.00 06/01/1998
I need to populate the adir field where the adate < 12/31/1998 with the rate where adate = 01/01/1998.
I cant seem to figure out exactly how the statement should go so that I populate each timekeepers rate with their specific rate.
Thanks

Is there any way to create a "dynamic" update statement in a stored procedure?
Lets say I want to choose whether to update all columns in a table or just one. If I want to update just one column, is there a way to make the other columns keeping their values instead of NULL?
Thanks!
Pete

I am looking for a solution to my unique problem.
myTable is having following records
ID Field1 Field2 Field3 Field4
1 x y 100 0
2 xx zz 5 0
3 x y 200 1
4 a b 1 1
5 a b 2 0
6 k L 78 1
7 aa bb 25 1
8 k L 15 0
Now the problem is if I want to update a latest record's(if you go by ID)Field4 with 2 for the records where Field1 + Filed2 is unique, can I do this in a single query?
I can select the unique record by the following query
select Field1,Field2 from myTable group by Field1,Field2 having count(ID)>1
Any ideas?
