Access To SQL Server 2000 Pauses With Lots Of Inserts, Updates, ...
Nov 21, 2007
Hi,
I have the following problem: Within a VBScript, I use a component (written in C++ I think with use of ADO) for sending "Insert", "Update" Statements to an SQL Server 2000 for inserting, updating data. If I insert 100 - 120 Records in a Loop, all works fine. If I insert 1000 records, approximately 150 records will be inserted very quick, then the program pause fo approx. 8 - 15 minutes and then it proceed for the next 150 recs, pause for 8 - 15 minutes and so on.
If I use a SQL Server 2005 for the database, all works fine. The same happens with another customer and another program written in Visual Basic 6.0 with ADO. The access to SQL 2000 pause and with SQL 2005 all works fine. It seems to me that this is a problem with some buffers, timeout, or so. Has anyone an idea on what screw I can turn?
Thanks
Hans

Hi,
I am working on an application to analyse down time on a production line system. The system has about 40 rows inserted per minute. The inserts are coming from about 10 different stations.
I need to a analyse the downtime between each insert from each station. The plan is to copy the data to another database on a different server so as not to affect the live system that is being updated by the production line.
However the initial requirement was to do this at night while the production line was down but now they want the data to be updated every 3 hours which means performing this huge query while the production line is bombarding the DB with inserts.
I am wondering what is the best way of doing this. Is there any way I can limit the abount of processor this proceedure will take.
Any advice appreciated,
Thanks,
Sean

Hi All,
I'm a relative novice on SQL Server and am a complete beginner at SQL, so am looking for a little help.
I currently use a DTS package to perform inserts / updates to a "production" table.
The DTS package transforms a comma separated file into a "temporary" table that is truncated / cleared before the load starts.
The temporary table has a column denoting Insert or Update. The production table is almost identical, however, doesn't contain the Insert / Update column. The DTS package then, depending upon the Insert / Update flag, either inserts data into the production table or updates data in the production table.
When the DTS package has completed, I'd like to be able to run an SQL Query that validates everything in the "temporary" table is identical to that in the "production" table, which it should be.
I have managed to do some queries to verify that everything has loaded / updated i.e. select primary_key from temporary table where primary_key not in (select * from production table), however, what I haven't been able to do is verify that all the columns on the temporary table match the values in the production table (excluding the Insert / Update flag).
I tried concatenating the columns in each table and comparing the concatenated values, however, this failed due to the different data-types, i.e. decimal, text etc.
Any help will be greatly appreciated.
Many thanks.
Cheers,
David

I have a database setup and the fields setup as nchar(200).
Now, when I update a row using the code below it inserts the text but then seems to fill the rest of the field with spaces. i.e. if the text is only 10 characters, mssql seems to put 190 characters on the end of it to make 200.
Is there any reason how I can stop this/1 // Create new command
2 comm = new SqlCommand(

Hi...
I have data that i am getting through a dbf file. and i am dumping that data to a sql server... and then taking the data from the sql server after scrubing it i put it into the production database.. right my stored procedure handles a single plan only... but now there may be two or more plans together in the same sql server database which i need to scrub and then update that particular plan already exists or inserts if they dont...
this is my sproc...
ALTER PROCEDURE [dbo].[usp_Import_Plan]
@ClientId int,

SET @Status = 'Updating plan information in Plan table.'
UPDATE
Statements..Plan
SET
PlanName = PlanName1,
Description = PlanName2
FROM

AND
(
IsNull(cp.PlanName,'') <> IsNull(c.PlanName1,'')
OR
IsNull(cp.Description,'') <> IsNull(c.PlanName2,'')
)
SET @Count = @@ROWCOUNT
IF @Count > 0
BEGIN
SET @Status = 'Updated ' + Cast(@Count AS varchar(10)) + ' record(s) in ClientPlan.'
END
ELSE
BEGIN
SET @Status = 'No records were updated in Plan.'
END
SET @Status = 'Adding plan information to Plan table.'
INSERT INTO Statements..Plan (
ClientId,

Hi
I have 3 table (tbl1, tbl2, tbl3).
tbl1 colums ---Pid(autonNumber),Pcode(unique values),PGuid
tbl2 columns---Pid, CatId,Fid
tbl3 Colums----Pid,BundleId
Using Trigger(After Insert) in tbl1 to insert the data of tbl1.Pid to tbl2.Pid and tbl3.Pid . tbl1 will be uploaded with new rows and existing rows will be updated from the csv file.
Trigger in tbl1 works fine by inserting data to tbl2.Pid and tbl3.Pid.
My questions are :
1. Is it possible to use trigger to update tbl2 and tbl3 if records exist if not insert new record to colum Pid in tbl2 and tbl3 from Pid of tbl1
2.Or is it possible to use sql procedure to do cascaded updates or inserts by merging datasets from tables and csv file using asp.net
3.Or How can I use single Trigger to insert if not exist and update if data exist.
4.Or Do I have to use two trigger one for insert and one for update. If this is the case how do check for data existance.
After insert Triger I am using at the moment is below (replied as an answer in this forum for my previous thread)
create trigger t1 on tbl1
after insert
as
begin
declare @id int
select @id=pid from inserted
insert into tbl2(pid) values(@id)
insert into tbl3(pid) values(@id)
end

I am looking for pros and cons for the following scenarios:
When a table contains a unique key constraint is it viable to always do an insert and immediately check the @@ERROR value and if @@ERROR states a duplicate key exception then perform an update statement?
Another possible solution would be to always check if the key exists and then do the insert / update based upon that result. This method will always require two steps.

Hi:
We have a weird problem in our test SQL 2005 SP1 - Windows 2003 Enterprise SP1 - Server (after upgrading from SQL 2000).
While changing data via JBOSS - JDBC connection, we get all our data modifications rolled back.
Selects are fine. Same SQL 2005 Inserts/Updates through JBOSS are fine on other machines with Windows XP (JBOSS is on the same machine there, while in troubled configuration it's on its own server).
But in production imitation environment we can't modify data.
Please advise where to look for the solution.
Thanks.

We recently upgraded from a HP LH3(Dual PIII 550, 512MB, NT 4 SP6, MDAC 2.5, SQL 7 SP3) to a new Dell 2550: (Dual PIII 1.26, 512 MB, NT 4 SP6, MDAC 2.6, SQL 7 SP3).
Our system is comprised of a service that listens on a port and then sends the requests to a Transaction Server,
inserts stuff into the database and then goes back the other direction to send the response.
We have a stress tester that we can start multiple threads and send different type of transactions. One of these transactions is a simple ping, just a header and footer that gets inserted into the database and then a header and footer is returned to the client.
Our problem is that these are working correctly on the live database server and our live (service) workstation, as it will send thousands of pings without stopping. On the new server it will stop on 35 pings, pause for several seconds, then send another 35 pings, pause, this cycle continues. (No, we don't have any code inserted to do this :P)
We have watched the Performance Monitor and see nothing out of the ordinary. We have ran a trace on both the test server and this new server. Near the end on the new server's trace it shows the disconnect twice with a duration of 40094 and then it starts up with a call to the sp_sqlagent_get_perf_counters. This trace only had the SQL command and stored procedure events. We had ran a trace that contained all events and stress tester actually worked without pauses. But this slowed down the transactions too much, and isn't really an acceptable resolution.
Has anyone ever encountered this problem? Any options that need to be set?
Thanks,
G.

Hello people!Here is the situation:We have an old propriatary database that is used for daily tasks. Not much we can do with it, but we have to use it.I can create basically a read only connection to it through ODBC.I would like to, on a timed interval copy certain data for reporting from this slow thing to my SQL server so that I can learn to program, and create some cool reports etc without having to wait on this server all day.So here is what I don't quite understand.I had originally planned on just deleting the contents of the tbl on my SQL server just before I populated it each time, but found out that my AutoNumber field will continue to increase, and I'm assuming that eventually I'm going to run into a problem as a result.Should I be doing some kind of update instead? if so do I need to first CHECK if the record exisit, if not then do an insert, if so do an update type thing?Or is there a way to basically do it in one command?I hope this makes sense. I would show you some code but there really isn't much to show you other than my insert statement :->Thanks for any advice!Josh

Hopefully someone can at least point me in the right direction for moreresearch (e.g.: correct terminology). My only previous experience was justdumping data into a database using ODBC, and that was some years ago so nowmostly forgotten.I need to write an NT Service/Application (in C/C++) that will be gettingdata sent to it via SQL Server 2000. The data will arrive in my SQL Server(read-only access), via replication of tables from another remote SQLServer.My application needs know when new row are inserted, or updated so it can toread this data (needs to be quick/timely so hopefully no polling) to theninterface with other remote proprietary systems.T.I.A.PS: If you can recommend appropriate books on SQL Server 2000 that wouldalso be useful.

I have transactional replication set up between two SQL Server 2000 databases. In some cases when I perform an UPDATE on a published table on the the publisher, SQL Server attempts to perform a DELETE followed by an INSERT on the subscriber using the stored procedures created during the initial snapshot.
Why does it do this?
How can I stop it doing this and force an UPDATE on the publisher to call the UPDATE procedure on the subscriber?
Thanks

Hi all,
This managed application was written to run on a Symbol 3090 Win CE 5.0 scanning device. We are using the symbol provided classes to access the scanning interface, and SQL Compact database on the device to collect the scanned data, and then using merge replication to synchronize scanned data when the device is docked. The problem we have experienced seems to be releated to the performance when inserting and updating records in the database.
We have tested some randomly generated 1000 records and inserting/updatating into a database. At first the time to commit a record increases when the database is flushing into the memory (The flush interval in the connection string property is 10 seconds by default). and then as the database size grows increasing the time to commit every single record which is causing the application to perform slowly as they scan items into the database. However, the device program memory remains consistant as they are scan items. From our tests, I found the time to execute either a update/insert command on 2MB sqlMobile database (upto 10000 records, depending on the size of the columns) is taking nearly 2 to 2 and half seconds to complete. Below is the only code I am executing,
If Not sqlObj.UpdateItem(1061022, itemNo, 1) Then
sqlObj.InsertResultSet(1061022, itemNo, itemObj.Style, itemObj.Color, itemObj.Size, itemObj.Description, 0, 1)
End If
For the notes, I am using prepared updated command and resultset.insert methods to perform update and insert commands into the database.
Any help on this issue is highly appreciated.
Thanks
Ravi.

Ok, I think this may have a simple answer. Basically I have no problems in setting up QueryString/Control/etc parameters when I use SELECT in the Configure Data Source Wizard as it prompts me for the necessary parameters. But when I try to use the Configure Data Source Wizard with an UPDATE, INSERT or DELETE it does NOT prompt me for the required parameters.Is this a bug or am I just missing something? Do I have to put them in manually or something?Thanks!

I have a 14GB database whose data content is legacy and is described as static. The log file is significantly large and continues to change size mostly increasing by 2-5GB a day (~60GB now) I have observed over the past two days; it shrank once unexpectly by a few GB. The instance is hosting other databases such as: EnterpriseVaultDirectory, EnterpriseVaultMonitoring, EnterpriseVaultStore, and NetPerfMon - might these seemingly unrelated data sources be involved?
I am trying to a trace to find traffic against the tables, no such luck.
Web applications are playing against it for queries but there should be no UPDATEs beign applied. I can only suspect that other unknown applications are performing operations but have yet to find unexplained connections.
Are there any other reasons why this type of log file activity would happen merely due to queries or stored procedure calls?
Lets also state, "mirroring, indexing, replication" are not at play. I know logging "Full" is not necessary as "Simple" should suffice but I am still hunting down why UPDATEs might be getting through. I realize I might adjust the migrated SQL 2000 security model to deny updates to find what breaks but would rather not take that iniative yet.
The installation is a fresh SQL 2005 Standard setup with SP2 applied; the databases were upgraded.

We have a SQLServer 2005 Enterprise merge replication publication with SQL Mobile 3.0 subscribers (Windows Mobile 5.0 and 6.0). We do not use pre-computed partitions due to trigger performance issues with an SSIS/ETL application that supplies data to the merge database. We do use the "Optimize" (=true) option, though we have tried this both ways with no significant differences. We use filters and joins for each worker ID (as HOST_ID) from the subscriptions.
The sync times become increasingly worse after we run the snapshot and bring the publication online. I have tried rerunning the snapshots, this helps little, as it often behaves like the subscription was set to reinitialize and forces a big sync (reload of all data) to the subscriber. We have tried much of the obvious (e.g., flattening filters and joins, adding indexes, etc.).
When users are synchronizing, we watch replication monitor and notice that a lot of time is spent processing "enumerating inserts and updates for article [any article]", especially processing the many generations and batches. This is true for any follow-up syncs after the 1st big sync (initializing the subscription).
I read several posts regarding the batches and generations of changes, and decided to try increasing the €œDownloadGenerationsPerBatch€?. I tried adding this parameter to the snapshot agent job, and the job fails each time with a vague message, even with the default value of 100. How do you change this parameter for SQLServer 2005 Enterprise?
Any suggestions?
Thanks in advance,
Matt

Hello guys och dolls.
I have a DTS program in sql-server 2000 which worked to week 27 but not from week 28. During that time I was on vacation och no one else was working with the server.
The part which is the problem looks like this.
if exists (select * from dbo.sysobjects where id = object_id(N'[lenko7].[aviskydd]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [lenko7].[aviskydd]
GO
CREATE TABLE [lenko7].[aviskydd] (
[Col002] [varchar] (255) NOT NULL,
[linecount] [int] NOT NULL
) ON [PRIMARY]
GO
I have not changed owner.
I don't understand why this DTS package suddenly cant work because it has been working for a several years with no problems. The only thing a know is that we have updated windows 2000 cause of a critical updates Juli 13.
Is there anyone who has the same problem.

Hi,
I have few tables. I want to identify the RECORDS for a table which has been created/modified for a particular date and time. I don't want to write a trigger to capture the event for add/update.
Is there any system table which track for date and time using stored procedure each individual records which has been last updated or newly created records??
Note : The application already created without lastModified date and each table... so, we don't want to modify the application or db.

I am kind of baffeled. I have a table with a column of 8 varchar in 2000
and the same in 6.5. When I insert into 2000 with a data length of more than 8 chars via Cold Fusion into the table, it fails. The same Cold Fusion
program inserts into the 6.5 table, but truncates the data but does not fail.
Does anyone know why this happens. Thanks, Newbie.

I've created a small company database where the tables reside in a SQLServer database. I'm using Access 2000 forms for a front end.I've got a System DSN set-up to SQL Server and am using links withinAccess 2000 to get to the SQL Server tables.My forms worked fine until I made a few minor changes to the databaseschema on SQL Server (e.g. added a foreign key, or added a column).After that, all the links break - I click on a table link and get anerror msg like "invalid object name."Deleting the links after a schema change and re-adding the links seemedto fix the problem. The forms I'd already created seemed to work fineafter re-creating the links.But then I got more advanced with my forms. I have it set up so thatfor certain entry fields, the combobox gets populated with values froma table (the description appears in the drop-down and the correspondingprimary key value gets populated in the table). I created a number offorms using this technique, entered data, and everything worked fine.Made a small schema change and it broke everything -- not the actualtable links, but the functionality for the drop-downs. My values nolonger appeared, and this was true for forms that accessed tables whoseschemas did not change.This is driving me nuts. Is there any way to keep my forms frombreaking each time I make a small schema change?Thanks.- Dana
