Large Amount Data Deletion Blocking Other Operations
Jan 30, 2007
Hi Experts:
We have several database linked via merge replications. Due to business requirements, we need to delete 5M rows in one table, we did it on one subscriber. However, the publisher kept uploading the deletion operations from the subscriber and blocked any downloading operation from publisher to subscriber. How can we acceralte the replications now as this has already operated in 2 days, and will continue 1-2 days? Is it possible to set the publisher take the downloading before uploading? How to speed up large amount data deletion operations in replication environment?
Thanks in advance!

I need to delete data from a particular table which has more than half a million records. The data needs to be deleted is more than 200,000 records from the table. What is the best way to delete the data from the table other than importing into a temporary table and performing the same operation?
Let me know if the strategy to be followed is okay.
1. Drop all the triggers
2. Drop all the indexes
3. Write a procedure with a loop setting ROWCOUNT to 1000 and delete the records. ( since if I try to delete all the rows it will give timeout error )
The above procedure will delete 1000 records for each batch inside the loop till it wipes out all the data for the specified condition.
4. Recreate Indexes and Triggers.
Please let me know if there are any other optimal solution.
Thanx,
Zombie

Hi,I am using SQL 2000 and has a table that contains more than 2 millionrows of data (and growing). Right now, I have encountered 2 problems:1) Sometimes, when I try to query against this table, I would get sqlcommand time out. Hence, I did more testing with Query Analyser and tofind out that the same queries would not always take about the sametime to be executed. Could anyone please tell me what would affect thespeed of the query and what is the most important thing among all thefactors? (I could think of the opened connections, server'sCPU/Memory...)2) I am not sure if 2 million rows is considered a lot or not, however,it start to take 5~10 seconds for me to finish some simple queries. Iam wondering what is the best practices to handle this amount of datawhile having a decent performance?Thank you,Charlie Chang[Charlies224@hotmail.com]

I have SQL 2000 and need to retrieve fairly large amout of data (~50.000 characters) in XML format and then insert it into the field ofthe text type.As 'FOR XML' can't be used with either local variables, INSERT INTO orSELECT INTO this makes "XML support" quite useless in many aspects.Can anyone please help me in solving this.Thanks a lot for your help and time.Pavel

Hi,
My application needs to retrieve data from a table which has more than 15 lakh records. The records keep increasing in thousands every 15 days.
Is there anyway i can reduce the time to retrieve? basically i have a select statement with a few conditions and a clause for the id's of these records.

I have an interesting challenge. we are not allowed to allow users direct access to data in our SQL Server. Audit requires us to take the data out of our production server and pass it to the user. my situation is i have a table in SQl with over 100,000 records and growing. i want to pass that to an access data base. i am utilizing DTS and a data transform.
i s there a better way? the package is running slow and even appears to freeze. i see this amount of data as growing as well.

Recently we added a new table into our SQL2000 database specifically to store scanned in images of documents. This new table contains a PK field, a couple of datetime fields, a couple of char(1) fields and one 'image' field.
Before adding this table, the database size was approx 6GB. Six months after adding this new table, the database has grown to 18GB - 11GB of this is due to the scanned in images.
Would this new table affect the SQL performance with regards to accessing other data in the database that has nothing related to the new table?
If so, would moving this new table into it's own database be recommended?
Thanks

I have a combo box where users select the customer name and can eithergo to the customer's info or open a list of the customer's orders.The RowSource for the combo box was a simple pass-through query:SELECT DISTINCT [Customer ID], [Company Name], [contact name],City,Region FROM Customers ORDER BY Customers.[Company Name];This was working fine until a couple of weeks ago. Now wheneversomeone has the form open, this statement locks the entire Customerstable.I thought a pass-through query was read-only, so how does this do atable lock?I changed the code to an unbound rowsource that asks for input of thefirst few characters first, then uses this SQL statement as therowsource:SELECT [Customer ID], [Company Name], [contact name],City, Region Fromdbo_Customers WHERE [Company Name] like '" & txtInput & "*' ORDER BY[Company Name];This helps, but if someone types only one letter, it could still bepulling a few thousand records and cause a table lock.What is the best way to populate a large combo box? I have too muchdata for the ADODB recordset to use the .AddItem methodI was trying to figure out how to use an ADODB connection, so that Ican make it read-only to eliminate the locking, but I'm striking outon my own.Any ideas would be appreciated.Roy(Using Access 2003 MDB with SQL Server 2000 back end)

guys,I have a project need to move more than 100,000 records from onedatabase table to another database table every week. Currently, usersinput date range from web UI, my store procedure will take those dateranges to INSERT records to a table in another database, then deletethe records, but it will take really long time to finish this action(up to 1 or 2 hours).My question is if there is some other way I should do to speed up theaction, I am thinking about use bcp to copy those records to datafileand then use bcp to insert it into SQL Server table. Is this the rightway to do it or should I consider other solution (then, what is thesolution.)Thanks a lot!

We have created a databse in SQL Server 7 for support issues.
We are having trouble with only one aspect of the databse and that is the body of the supported problem.
The databse is basically a Question/Answer Support database whch house Frequently Asked Questions.
When the user does a search on a specific problem they have a list of matching questions shows on the screen (links).
When the question is clicked on it shows the Questions with the Answer of possible fixes.
Our problem lies in the fact that SQL server is truncating the Answer portion. I have tried different Data Types with maximum lengths with no success it keeps truncating it.
Right now I am on Data Type nvarchar with a length of 4000.
If anyone has any pointers on how to solve this problem all input is appreciated. You can post here to the forum or e-mail me directly at jason@flnet.com
Thank You.

Is there any way how to create indexies after insertion of any
number of records (I dont want to create index after insertion of every record,
but for example after insertion of 1000 records) ?
I heard it should be possible with „bulk insert“ or with
transactions. Is it right ? I need do this with MS SQL Server 2005 (Workgroup
edition).
Thank you for your ideas!

Hello all - I currently have a project that has a gridview on the front end. The user can select multiple items from this grid, hit a button and all of the selected records should be updated in the process. However, this resultset can have a large amount of data coming back, and I'm stumped on how to pass all of the ID's to the sp. I'd rather not call the SP for each record selected, as there could be 1,000 items selected, and well, I'd rather not call the SP 1000 times :p. I thought of generating a comma delimited list as I'm looping through the grid and using dynamic sql, but the IDs are about 6-7 numbers long, and including comma, would take up almost all of the max space in a varchar.
Are there any good solutions to this problem? Passing the items as an array? Generating a data table in .NET and passing that?
Any help would be appreciated.

How can I make a recursive algorithm in TSQL without using a large amount of resources?
New hires are put on a 6 month probation period, Their probation ends at the 6 month mark + sick time isnull(floor(sick_hours/8),0) they accrued during that 6 months. Their accrued sick days are added to the 6 month probation period to establish a new probation end date.
I then have to do the following loop:
1)Determine if any of the days between the original probation end date and the new probation end date have any weekend days or holidays for a particular employee.
2)If it does, I add those days to the new probation end date to create a newer probation end date.
a.I then go back up to step 1).
3)If it does not, I jump out of loop and look at the next employee on probation.
Note: I already have coding for determining number of sick days accumulated during an employee’s probation period. Recursive CTE? Recursive function? Other?

I am having a small problem.
When I generate a report with a large amount of text data (Paragraphs) the report will not split the text between two pages.
It will move the entire text box to the next page leaving a large amount of space on the previous page.
I tried every control on the page to render this. I tried textboxes, tables, lists, rectangles, subreports, etc..
The data is stored in a SQL table using a text data type (there can be a large amount of data entered into these database.
Any help on this would be great. I like reporting services, but there are just a few bugs.
I am using Reporting Services 2000 with Service Pack 2 and Hotfix
http://support.microsoft.com/?kbid=912424 (That fixed a different PDF rendering issue) and this problem was occuring prior to this hotfix.
Thanks in advance

In the full recovery model, if i run a transaction that inserts 10MB of data into a table, then 10 MB of data is moved in the data file. Does this mean then that the log file will grow by exactly 10MB as well?
I understand that all transactions are logged to the log file to enable rollback and point in time recovery, but what is actually physically stored in the log file for this transactions record? Is it the text of the command from the transaction or the actual physical data from that transaction?
I ask because say if I have two drives, one with 5MB/s write speed for the log file and one with 10MB/s write speed for the data file, if I start trying to insert 10 MB of data per second into the table, am I going to be limited to 5MB/s by the log file drive, or is SQL server not going to try and log all 10 MB each second to the log file?

We have an employee table that contains bank details and are experiencingproblems with account numbers being erased and lost. In order to track downwhy this is happening (either due to our application code or SQLreplication) we'd like to be able to prevent certain columns from beingdeleted if they already contain some data.Is it possible to setup a check constraint to prevent our ee_acct_no columnsfrom being set to NULL or blank strings if it contains an account number(i.e a 9 digit number)? We have setup the column to allow NULL's as we don'talways know employees bank details until later, so we do need to put them onour database without bank details initially.Also, if possible, can someone suggest a stored procedure or trigger i couldcreate that would fire a user-defined error message that would email anoperator if a bank account number changed?Many thanksDan Williams.

We have been asked whether it is possible to completely delete sensitive data. When data is deleted it is not actually completely removed from the database but is marked as deleted. It is possible to zero out that data using sp_clean_db_free_space but this doesn't affect the transaction log.
We had hoped that CHECKPOINT would clear the data from the log but we are not completely certain of this. So the question becomes is there a built-in command or function in SQL Server 2008, or subsequent versions, that will completely remove deleted data, both from the transaction log and the database itself? Or is there a 3rd party tool to accomplish the same thing?

Hello,
I have not been able to locate information on the following problem. The first step I have in a packge (Execute SQL Command) is to delete the data from an MS Access database table. The package hangs at this step after all validation is complete. In the package, once the table data is deleted, it is repopulated in a later step. The deletion step and the repopulation step use the same connection manager.
There is no information in the log about an error. At the time the package ran, there was a lock file on the database with about six users connected. I'm not sure what version of Access the database was created in, but I have 2003 on my machine, and I cannot open the database.
Any ideas?
Thank you for your help!

I'm creating a temporary table in a Sql 2005 stored procedure that contains the transaction amount entered in a period <= the period the user enters.
I can return that amount in my result set. But I also need to separate out by account the amounts just in the period = the period the user enters. There can be many entries or no entries in any period. I populate the temporary table this way:
SELECT
t.gl7accountsid,
a.accountnumber,
a.description,
a.category,
t.POSTDATE,
t.poststatus,
t.TRANSACTIONTYPE,
t.AMOUNT,
case
when t.transactiontype=2 then amount * (-1)
else amount
end as transamount,
t.ENCUMBRANCESTATUS,
t.gl7fiscalperiodsid
FROM
UrsinusCollege.dbo.gl7accounts a
join
ursinuscollege.dbo.gl7transactions t on
a.gl7accountsid=t.gl7accountsid
where
(t.gl7fiscalperiodsid >= 97
And
t.gl7fiscalperiodsid<=@FiscalPeriod_identifier)
And poststatus in (2,3)
and left(a.accountnumber,5) between '2-110' and '2-999'
And right(a.accountnumber,4) > 7149
And not(right(a.accountnumber,4)) in ('7171','7897')
order by a.accountnumber
Later I create a temporary table that contains budget information. I join these 2 temporary tables to produce my result set. But I don't know how to get the information for just one period. For example, if the user enters 99 as the FiscalPeriod_identifier, I need a separate field that contains only those amounts(if any) that were entered for each account in Period 99.
Can anyone help? It may be that I am not seeing the forest for the trees, but I can't figure it out.
Thanks very much.
