hi,
I'm using a OLE DB COMMAND component to perform an update (SQL statement) but the procces takes about 9 hours, so I changed it to a stored procedure but it was the same, I need to update about a a million of rows and the package is very simple.
How can I improve the time, Can I use another component or startegy?
thanks
Good afternoon everyone, I have written a view that pulls customer demographic infomration as well as pulling data from multiple scalar-valued functions. I am using this view to pull and send data from one database to another in the same SQL server. The problem that I am having is that I am running this import as a scheduled job in windows. The job is taking almost 24 hours to complete this task. The total number of records that are being pulled is around 21,000+. I have tried removing the functions from the view and it only takes the view 20 seconds to pull the demographic information from the same 21,000+ records but when I add the function calls this is where the time to complete goes through the roof. Has anyone encountered this before if so what would you suggest doing? Any help would be appreciated. Here is the syntax for my view: SELECT TOP 100 PERCENT CUS_EMAIL AS Email, CUS_CUSTNUM AS MemberID, CUS_PREFIX AS Prefix, CUS_FNAME AS FirstName,
CUS_LNAME AS LastName, CUS_SUFFIX AS Suffix, CUS_TITLE AS Title, CUS_STATE AS State, CUS_COUNTRY AS Country, CUS_ZIP AS ZipCode,
CUS_SEX AS Gender, CAST(CUS_DEMCODEA AS nvarchar(20)) + ',' + CAST(CUS_DEMCODEB AS nvarchar(20))
+ ',' + CAST(CUS_DEMCODEC AS nvarchar(20)) + ',' + CAST(CUS_DEMCODED AS nvarchar(20)) AS DemoCodes,

Hi,
I have a table with 48 million rows,when i executed following update query it is taking 10 HOURS in SQL SERVER 2000 with SP1.
Where as when i executed same query in SQL SERVER7.0 with same table then it is taking 13 MINUTES. Comming to Machine...SQL 2000 Server has more processors and greater memory than SQL 7.0 m/c.
It looks strange but this is true.Does any one faced such problem..is there any bug in SQL 2000?????
Here is Query::
update cus_pay_jan_dist set univ_regdate = b.dayid
from cus_pay_jan_dist a with (nolock), tm_dayids b with (nolock)
where a.univ_regdate = b.dayidnum and a.univ_regdate like '2001%'
Thanks

I have an update statment in my SSIS that use to take 10 minutes in SQL 2000 dts and now its take 1 hour 15 minutes in SQL 2005.
this is my sql update statment -
Update WeeklySalesHistory set
weekendingdate =
(SELECT LastTransDateTime from ReplicationControl
where TableName = 'WEEKHST')
where weekendingdate is null
It is using ole db connection. About 36,000 records that it is updating.
I have read ole db can be slow and to use staging table. Does that mean on all updates like this I have to use a staging table and then insert. I didn't use to have to do this in SQL 2000. Has it changed. Are there any other options?
any input greatly appreciated.
Dear Experts,

Im migrating data but its taking too long to commit insertion, what sould i do?

dear guys. i have this one problem, where the sql statements really took very long time to be processed. It took more than 1 minute, depending on the total data in the table. I guest this have to do with the 'count' statements. here is the code:
------------------------------------------------------------
$sql = "SELECT company,theID,abbs,A as Active,N as Nonactive,(A+N) as Total
FROM(
select distinct D.nama As company, C.domID As theID, D.abbrew As abbs,
count(distinct case when B.ids is NOT NULL THEN A.dauserid END) As A,
count(distinct case when B.ids is NULL THEN A.dauserid END) As N
FROM
tableuser A LEFT OUTER JOIN tabletranscript B on (A.dauserid=B.dauserid)
INNER JOIN thedommember C ON(C.entitybuktiID=1 AND C.mypriority=1 AND
C.entitybuktiID=A.dauserid)
INNER JOIN mydomain D ON (C.domID=".$getID.")
GROUP BY D.nama, C.domID, D.abbrew
ORDER BY company
)";
Hope any of you can simplify this statements into a query that doesnt take ages to be processed.
Thanks in advance....
I have a VB application which uses SQL server as the database and uses Crystal reports for reporting.We are using a stored procedure to create a report and we pass ID from the vb side to run the stored procedure.
In boston the report shows up in 4 sec.But in california it takes 7 min.
We have a very good network(T3).Why it is taking more time in california ?.
Any ideas ?
Hi,
I am running this query and it is taking over 3 minutes.
"select * from table1 where CONVERT(varchar(10),dated,5) = '13-09-01' "
Table1 has a column called dated which is datetime datatype.
Any suggestions how can i optimize this query?I tried Non-clustered index on Dated column and time came down to less than 3 but still more than 2min.

Hi guys.
I am having trouble in time issues while backuping my database.
My database size is around 50GB. It is taking around 5hrs.

Hello All,
I have SQL Server 2005 installed on my machine and I am firing following query to insert 1500 records into a simple table having just on column.
Declare @i int
Set @i=0
While (@i<1500)
Begin
Insert into test2 values (@i)
Set @i=@i+1
End
Here goes the table definition,
CREATE TABLE [dbo].[test2](
[int] NULL
) ON [PRIMARY]
Now the problem with this is that on one of my server this query is taking just 500ms to run while on my production and other test server this query is taking more than 25 seconds.
Same is the problem with updates. I have checked the configurations of both the servers and found them to be the same. Also there are no indexes defined on either of the tables. I was wondering what can be the possible reason for this to happen. If any of u people has any pointers regarding this, will be really useful
Thanks in advance,
Mitesh
Hi:
I have a query which returns approximately 50000 records, I am using a linked server to connect to two databases and retrieve data.

I'm running a query (see below) on my development server and its taking around 45 seconds. It hosts 18 user databases ranging from 3 MB to 400 MB. The production server, which is very similar but with only 1 25 MB user database, runs the query in less than 1 second. Both servers have been running on VMWare for almost 1 year with no problems. However last week I applied SP 2 to the development server, and yesterday I applied Critical Update KB934458. The production server is still running SQL Server 2005 Standard SP 1. Other than that, both servers are identical and running Windows 2003 Server Standard SP 1. I'm not seeing this discrepancy with other queries running against user databases.

Hi,
I have a DTS in SQL Server 2000, Where I am importing some data from a remote server (SQL 2000) to local server (SQL 2000).And this is working fine. it is taking max of 1 min to execute the package.
Now I have created the same DTS in sql server 2005 (SSIS) where the source server is sql server 2000 and the destination server is 2005.and I have created the ssis in that server. The same logic which i have created in sql 2000. But here it is taking almost 10 min to execute the package.
Where as the same in sql server 2000 taking max of 1 min. Why this happening.. Is there any configuration to execute the SSIS package.?
I have a SSIS package where a small table of 270 rows are fuzzy looked up with a table in another sql server and inserts the records to a temporary table. This takes more than 3 hours in debug mode or so and never goes beyond this step.I have used a OLE DB destination to insert to temporary table and temporary table doesn't get a value.
View 2 Replies View Relatedi have sql 2000 db of about 120 GB. its taking about 10 -12 hours to restore on the same disk as new database.
server configuration is good.
when i try to restore another db of about 10 GB size, its restoring in about 5 minutes.
Sometime is necessary to stop MSSQLSeverOLAPServieces to do a full backup in my OLAP Server disks. After backup had finished and I tried to star MSSQLSeverOLAPServieces but it takes almost 30 minutes to the services starts.
What can it be causing that?

I have a stored procedure that normally takes about 5 hours to complete:
DELETE tblX WHERE PROC_DT < dateadd(day, -93 , getdate())
tblX has about 55 million records and has an index on PROC_DT.
I have this running as a scheduled task. Over the weekend, the task executed and it is still running 56+ hours later. Does anybody have any ideas as to where I should look for the problem? I am afraid to kill the process because of the rollback time.
Hi
I have one stored procedure and its taking 10 mins to execute. My stored procedure has 7 input parameters and one temp table( I am getting the data into temp table by using the input parameters) and also I used SET NOCOUNT ON. But if copy the whole code of the SP and execute that as regular sql statement in my query analyzer I am getting the result in 4 seconds. I am really puzzled with this.
What could be the reason why the SP is taking more than query,Unfortunately I can't post the code here.
Thanks.
Hi All,
Scenario:
There are two applications running on different server say ServerA and ServerB. Both applications are using same database server SQL Server 2005 say ServerB. Called the application as ApplicationA and ApplicationB with respect to Server names
It means for ServerA the database is remote and for ServerB, database is local.
Both the applications are Java application and using datasource to connect to the database. The driver used are SQL Server 2000 driver (which includes 3 jars). This can be a question that why 2000 driver is used for 2005. The reason is, application on ServerA is getting error while using SQL Server 2005 as Driver not proper.
Problem Area:
When ApplicationB (local to database) is doing some DB operations (which includes select and then batch insert), ApplicationA (remote) is trying to insert a record which is taking too long time (around 40 sec.). This is causing timed out in ApplicationA.
ApplicationA is inserting the data into the same table from where ApplicationB is selecting the data.
Any help????
Cheers

Does the validation time of DTSX package depend on the amount of data?
I have a data transfer task which contains a oledb source data from a SQL Server 2005 view. Then the data go through 3 Lookup transfromations before going into another view, also on SQL Server 2005 but a different database.
The purpose of this package is to load fact data, so it has to deal with few million of rows. Before setting DelayValidation to true, it takes few minutes just to open the package in BI Studio. Now with DelayValidation set to false, I can open the package without any problem. But it takes more than 5 minutes during Validation, Prepare for Execution and Pre-execution Phase. During the time the memory usage and cpu time on SQL Server goes up significantly. The CPU doesn't hit 100% though. My client machine doesn't have any significant activity.
I have similar packages ( Oledb view -> 3 or 4 lookup Transformations -> Oledb Table) but dealing with dimension data. With DelayValidaion set to False, those packages can be opened in BI Studio within few seconds. They also take only few seconds during those 3 phases before starting actual execution phase.
So I have an impression that the validation time depends on the amount of data in the database. Shouldn't it just depends on the metadata?
Hello,
I'm trying to figure out why my transaction log backup is taking up to an hour to complete. I started off with a full recovery model with a Full database back up every Sunday, differential backups every Tuesday/Thursday and log backups every 5 minutes. I would have thought that the log file backups would execute much quicker because I'm backing them up more often.
Here is my backup statement, I'm hoping I've got a wrong option that you can point out to me:
BACKUP LOG [xxxx] TO [LogFilexxxxBackups] WITH NOINIT , NOUNLOAD , NAME = N'xxxx log backup', SKIP , STATS = 10, NOFORMAT
The process is as follow,
The destination table is truncated and indexes are dropped before loading and after data being inserted we re-create the indexes.
Before this, a view extracts data from more than 22 tables from a staging database and tries to insert this data in the destination table.
it used to take 12-15 mins, but since yesterday loading one particular table never completes. While loading, the database is set to Simple recovery. There are no blocking. It's part of a daily batch thats loads 6 GB of data everyday. But while loading on particular table it's just keep running for hours. I tried rebuilding the indexes and re-starting the SQL Server but of no use.
Any help is much appreciated as this production batch job.
Thanks in advance.

Hi
I have Lookup task to determine if source data should be updated to or insert to the customer table. After Lookup task, the Error Output pipeline will redirect to insert new data to the table and the Output pipeline will update customer table. But these two tasks will be processing at the same time which causes stall on the process. Never end.....
The job is similiart to what Slow Changing Dimention does but it won't update the table at the same time.
What can I do to avoid such situation?
Thanks in advance,
JD
I have a backup mainentance plan that does a full backup daily at 03:00am and then 2 minute transaction log backups throughout the day to a raided hard drive (It is set to overwrite after 2 weeks), When i go into enterprise manager and select the database to restore it just seems to take too long to read the backup history in. Can this time be reduced as i need to be able to restore the database A.S.A.P but still need a point in time restore to within 2 minutes of going down??
Thanks
I have SSIS Projects taking a long time to open with packages with a large number of data flows. Is there a way to turn off validation of metadata when a package opens? Turn off validation during execution on SSIS Service (after previously validated in dev)? Or be able to control when validation takes place in general?
In my one package (1 of 5) I have 43 data flows (with a single source to target mapping) in 4 sequence containers, and it takes approximately 2-3 seconds per source to target mapping and sequence container to validate which will translate to 1 ½ to 2 ½ minutes to open. When the project with all 100+ tables for the data warehouse goes through validation, I can make coffee in the time it takes to open the project. I have to delete *.suo file (or verify all packages are closed in the designer and save the project file), and when I open the project, I have to jump immediately to SSISÃ Work Offline to set it to not validate the metadata to be able to work in a timely fashion. DelayValidation=TRUE does not help much.
Running in debug mode, has an effect of causing packages that were not open and validated to go through validation though I am not running those packages. Validate once during design and run forever.
Even if I re-open a package that I just closed from designer and had gone through validation, it will go through the validation process again.
It would be great if there could be an on-demand option off the menu bar to allow one to control when validation can take place for a project, or a more granular validation option for a specific data flow or container.
I have a CLR stored proceudure than runs under 2 or 3 mins when run in management studio. But when the report calls the same SP, it runs in around 30 mins and the CPU usage goes to 90 or 100% and the sqlserver service uses massive amount of memory. Previously the report worked fine, only after made a few data driven subscriptions and redeployed the reports with minor changes that it began to happen.
