Need Lil Fast Help
Jan 17, 2006
my system has 2 db's - sql server 2000 & db2 @ separate locations. i have a select query which needs 2 pick up consolidated data from both the tables. also the schema on the db2 has minor changes when compared with the schema on sql server 2000.
while searching on microsoft i came across the technique of creating a linked server. would this be possible 2 implement in my scenario. also would in this case, be advised that i create another view in the db2 server which has changed the db2 schema to the sql server schema format??
please hurry..
regards,
sameer

4. We don't won't use Cluster.
Once in while becouse of nethwork, or other problem log shipping fails,
so I have to restart log shipping all over starting from restore in stand by mode last full back of my db.IT takes 2-3 hrs just to do this restore !!!
1. So I am asking advice is any way I can bring down time for restore ?

I have stoopidly enough deleted default Db. That causes Enterprise Manager to be unable to work with my DB's. The default DB I deleted had no other functions other then being default DB, I mean it was outdated, and I had other DB's that contained all my importent work. They are still running, and I can view DB driven site hosted at localhost, even though default DB no longer excist. I am even able to upload new content, or add new users, so this means all my other DB's are fine. I can even see SQL server icon in my bottom right corner of my desktop, and it shows server running.
Now I am in the need of adding tables and rework some of my excisting tables and stored procedures, but I am not able to do that with Enterprise Manager, due to the lack of default Database.
How do I correct this problem? I have gotten one tip of doing the following: EXEC sp_defaultdb 'User', 'DB' but I am not sure what to do with this.....tried to run it from command line, and put my username and the DB I would set to default but nothing happend.
So I need more details, step-by-step guiding will work, as I don't know a hole lot about Enterprise Manager and SQL.
Btw, this is my error in Enterpr.Managr:
A connection could not be established to MyComputerVSDOTNET2003
Reason: Cannot open default database. Login failed..
Please verify SQL server is running and check your SQL server registration prpoerties and try again
Pls tell me there is a way to fix this problem.

Hello everybody,
please advice: what is the fastest standard method of user interface access to SQL database? I am looking for fast display of one master record plus related dependent records, plus fast scrolling through master records with display of dependent records as fast as posible. Perhaps a standard problem with standard solution? At current state of matters, I am still much slower then with my old Access97 database.
thanks for any advice,

I notice this morning that my tempdb grows very fast. I have 26GB in my
hardrive and all the space occupied by tempdb and finaly the qeury got failed due to 0 space in hardrive and there is no space to grow tempdb.
The select query supposed to bring about 40000 rows.
I ran this same query in different server that is not growing even 1 mb.
I checked the tempdb option the Trunc log on checkpoint is true.
Why this problem happening ?.
I have just dbo permission to access all the database.
Do you have any advice regarding this?.
Thanks,
Ravi

(Win2003, SQL Server 2000 SP4)
I have a database of about 5Gb of size. Some queries where taking more than 1 minute to complete execution (all of them are stored procedures). Because of that lack of performance, I call the command DBREINDEX for each table, executed the sp_updatestats system stored procedure and finally I executed the sp_recompile system stored procedure for each sp in my database.
After all this task, queries completed in a matter of a few seconds instead of minutes. Strange enough is that some hours later (about 6 hrs), after normal use (this database belong to a Client/Server information system), the problem appeared again: Queries started to take too long to complete.
I am assuming that indexes are degrading too fast so that they required another ReIndex, but I am not sure.
Any thoughts? How can I prevent this behaviour?
Thank a lot in advanced.

I have a weird situation I had not expected.....
I insert a record to a table and "later" I update it.
I have two fields to capture time information: Created and LastModified.
My update is very simple: update .... set ..,[LastModifiedDate] = GetDate() where id = @pId.
Now my problem is that I am seeing the created and lastmodified times as the same (in format 2007-09-05 12:38:42.383) !!??!
The record has definitely been updated (other fields are populated).
Can anybody enlighten me?

Hi,
I have made some stored procedures to check if a user is involved with a certain record. basically every stored procedure contains the following logic.
example spCheckClientRelated:
select @res = count(*) from client_role where client_id = @cid and employee_id = @eid
if (@res = 0)
begin
... next select
end
if (@res = 0)
begin
... next select
end
....
return @res
end
so far so good. But the final check in CheckClientRelated tests if a user is related to one of the sales projects for that client.
I allready have the spCheckSalesProjectRelated that returns 1 or 0 similar to the example above
so I want to find an efficient method that selects all the sales_project_id 's from the sales_project table where client_id = @cid (i use offcourse select @sid = sales_project_id from sales_project where client_id = @cid at the moment)
And then I have to execute the spCheckSalesProjectRelated method for each @sid and @eid. This if offcourse where my problem is located. I don't know how to do a fast check for every selected @sid, until spCheckSalesProjectRelated returns 1
As you probably can determine from my question, sql is not really my domain, and I'm certainly not an expert, but I don't mind reading or looking up some stuff, so even a clue or a direction to look in would be most appreciated
thx in advance.

I have a very puzzling situation with a database. It's an Access 2000 mdbwith a SQL 7 back end, with forms bound using ODBC linked tables. At ourremote location (accessed via a T1 line) the time it took to go to a recordwas very slow. The go to mechanism was a box that the user typed the indexvalue into a combo box, with very simple code attached:with me.RecordsetClone.FindFirst "[Index] = " & me.cboGoToIf Not .NoMatch ThenMe.Bookmark = .BookmarkEnd Ifend withNow, one would say that going to a record is slow because I'm using..FindFirst over a T1 line. And that's what I thought. However, as I wasworking with the form, commenting out various sections not related to the GoTo, I found that the Go To functionality changed, though I didn't modify thecode.Previously, going to a record near the end of the 50,000 record recordsettook about 1-2 seconds, but going to a record near the beginning, took about20 seconds. After the form changed, going to any record in the recordsettook about 1-2 seconds.So the question remains: why did it take so long to go to a record near thebeginning of the recordset, but not near the end (and the ones in the middletook an amount of time about halfway between the two), and what changed sothat now the form is working fine for all records?I've compared the changed form with the previous copy, and I don't see anydifferences. I've compared all code in the form module, and I've comparedall form properties. The forms are identical as far as I could tell. Butsomething happened as I was commenting/uncommenting code in the form thatgot rid of the problem with it taking a long time to go to some of therecords.My first thought was that something got recompiled, and now the form isfast. So I went back to the original version and changed some code andrecompiled, also did a compact and repair. But it was still slow. I alsotried doing an explicit decompile and then recompiled it. But it was stillslow.So this is very frustrating that the form is now working fine, but I can'tsee anything that's changed. If I don't see why the form is now fast, thenthere's no reason to believe that it might not at some point go back tobeing slow again. And then I'd just have to hope that something changes. Itwould be good to figure this out.Any ideas as to what might have changed here to cause the form's Go To to befast would be appreciated.Thanks,Neil

I have a table containing URLs. I want to be able to look up an URL veryfast, so I used an nvarchar to store the URL, and put an index on it(maybe naive).Anyway, I bump into:"The index entry of length 911 bytes for the index 'UQ__URL__1367E606'exceeds the maximum length of 900 bytes."What's the best way to handle this? I want to do the look up fast. Theonly thing I could think up was adding an extra column containing a digestfor the URL, and look up all URLs with the same digest, *and* having thesame value (which could give either 1 or 0 results).I am new to MS SQL, so I might describe a silly solution, basically I wantto look up URLs to ID the fastest way possible.--John MexIT: http://johnbokma.com/mexit/personal page: http://johnbokma.com/Experienced programmer available: http://castleamber.com/Happy Customers: http://castleamber.com/testimonials.html

I am trying to implement a very fast queue using SQL Server.The queue table will contain tens of millions of records.The problem I have is the more records completed, the the slower itgets. I don't want to remove data from the queue because I use thesame table to store results. The queue handles concurrent requests.The status field will contain the following values:0 = Waiting1 = Started2 = FinishedAny help would be greatly appreciated.Here is a simplified script to demonstrate what has been done.CREATE TABLE [dbo].[Queue] ([ID] [int] IDENTITY (1, 1) NOT NULL ,[JobID] [int] NOT NULL ,[Status] [tinyint] NOT NULL) ON [PRIMARY]GOCREATE INDEX [Status] ON [dbo].[Queue]([Status]) ON [PRIMARY]GOCREATE PROCEDURE dbo.NextItem@JobID integer,@ID integer outputASSELECT TOP 1 @ID = [ID]FROM Queue WITH (READPAST, XLOCK)WHERE (Status = 0) AND (JobID = @JobID)RETURNGO

I seem to remember reading many moons ago about a function where youcan retrieve a count of the last recordset you opened.For example:I've got a stored procedure that returns a recordset using the TOP 10so I only get the top 10 records. I need to know the recordcount but Idont want to reuse the SELECT statement because its quite complex.Any ideas?What does @@Count do?Thanks in advance

I think I am asking this in the right place.
I'm trying to get a record count from a table with 30million items and it takes forever.
Here is my code:
SELECT COUNT(f_id) AS 'ROWCOUNT' FROM tablename
Is there a faster way.
BTW f_id is primary key indexed.
Thanks

Templog is growing 1 GB per hour.
I've read some articles about this issue, that talk about how to shrink it.
In this case I need to find out what and why this is happening
How can I monitore it?
I know, sometimes, I exaggerate in using temporary files, in order to make reports faster.
The Tempdb size is normal.
Thanks

I have created an integration services package with a script-source reading data from Active directory. Pretty much data is read and written into a sql2005 database.
I have notised that when I run the package via right-clicking the package (Under stored packagesMSDB) and selecting "Run Package" it takes about 45 minutes for it to complete successfully. The same goes if I run the package from inside Visual Studio. However, when I create a job and put this package as one of it's tasks the task takes about 1h 40min. This is more then double the time! In neither case the server is occupied with soething else. And I have tried it several times so it wasn't just an "accident".
Any idéa of what this depends on?

What should I have done? Is there anything that can be done other than restoring from backup?
How does one know if the database is really recovering or is EM just joken? I can wait 2 hours
before starting the restore
I was BCPing 12 million rows into a staging table. II used the '-b' option every 20K which I thought
would do a commit and clear the log in batches. After the process EM appeared to show the transaction log
as empty. Upon inspecting the Bcp output file I discovered the message that the BCP did not complete
because syslogs was full. I could not do a truncate transaction log or a dump database. I tried to
do a truncate transaction with no_log and it appeared to just hang. I stopped the SQL Server thinking
I could dump the transaction log, but could not start the Sql Server again. I then stopped the NT Server
because 'if all else fails'. The SQL Server started but the user database if marked as recovering.

I'm trying to figure out how to determine why the same database is fast on my desktop but slow on a robust multiprocessor win2003 server.
I have a complex proc that takes about 27 seconds on my desktop sql server but takes almost 5 minutes on the server. The server processors are running at about 1% utilization while the proc is running.
Any ideas on how to troubleshoot this extremely poor performance?

Hi all,
I'm having a problem with one of our ddbb because we didn't run the maintenance plan from the beginning. The thing is that the hard drive is out of space and the log files are around 100GB. We only have 20MB free. Do you think that is space enought to run the maintenance plan or the shrink command??
Thanks very much!!!

I'm looking for a way to insert 50k records into a SQL Server table, and need to get it done faster. right now using BULK INSERT takes 5-10 seconds, but faster would be better, and even better if it were a consistent amount of time.
I've heard of DTS but don't know quite how to use it - would be offer any performance gains? any clue what the bottleneck is for BULK INSERT? hard drive speed? amount of RAM (this was on a 512mb machine)? parsing the fields?
thanks for any ideas.

I have a table that needs to be incorporated into the data warehouse.The table has the following schema.
CREATE TABLE [dbo].[Consignment](
[Id] [int] IDENTITY(1,1),
[BooingID] INT
[BookingDate] [datetime] NULL,
[CarrierServiceName] [nvarchar](255) NULL,
[CarrierServiceCode] [nvarchar](255) NULL,
[code]...
This Table has the same granularity as the fact table as it’s one row per booking.However due to the nature of the data I would not want to incorporate this into the fact table.The Originating and Destination addresses are populated for each booking and are required for reporting.
Question:Should this be moved into a fast changing Dimension table.? or would there be a better way to incorporate this data.

Hi everyone
I want to know if it's possible to do a for/while-loop so i can use INSERT
Look:
I've this int [] test = new test[140];
But i need to insert for every value (140) a number
so normally it would be :
INSERT ... (case1, case2, case3 ...) value (test[1],test[2],test[3] ...)
But isn't there a way to it with a loop?
SOmething Like this ?
for( int i = 0 , i< 140, i++) {
INSERT case[i] value test[i]
}
Thanks in advance
