Query Does Not Improve After Tables Defragmentation
Oct 22, 2004Hi ,
I have
SQL Server with 2 processors , 2 GB memory and RAID 5
40 GB db (Pricing ) working with 3rd party application.
in db Pricing
table A = 180000 rows (20 column and 5 indexes incling clustered primary)
table B = 1789000 rows (25 coumns and 6 indexes incling clustered primary )
table C = 10005 rows (15 columns and 4 indexes incling clustered primary)
Users start complaining about poor performance when selecting data from tables A,B and C
I used profier to capture all queries running with A,B and C tables
where duration more then 1 second.
Profiler shows 0 cpu and very high read for all capured queries
I run INDEXDEFRAG on tables A,B and C
then rerun Profiler
No changes at all in profiler reading
same low CPU and high read
If the is no changes in performance after INDEXDEFRAG can I conclude following
everything has been done to optimize tables A,B and C , query code or table structure should be modified?
or
any other improvment could be done without modifing code?
Thank you

Hard Drive Defragmentation Opinions
May 9, 2008I'm wondering what other people do in regards to running hard drive defragmentation programs on SQL Server 2005 servers (assume 64-bit and Windows 2003). From what I can tell the most common opinions are:
1. Don't defragment because it doesn't help and it can cause problems.
2. Use Diskeeper
3. Use the built-in Windows defragmenter
Other respected defragmented programs are PerfectDisk, O&O Defrag, JkDefrag, and Contig.
What is your hard drive defragmentation strategy?
SQL Security :: Shrinking Log Files With Defragmentation?
Aug 6, 2015I have a no of databases in full recovery model whose files are many times their datafiles. It is because these databases were copied from the development servers and in the development servers they were not taking the transactional log backups although once in the production server it is ensured that a transactional log is taken once in a day atleast. I plan to shrink the logfiles using the dbcc commands. However I am afraid that it may lead to severe defragmentation and performance hits.
We are using Sql Server 2008R2 enterprise edition which is clustered.
In this context my questions are:-
1)What is the best course to do the shrinking of log with out defragmentation?
2)Can I do the shrinking when the database is in use or is online in production?
3)Will the shrinking of the logfile improve the performance in any manner like that of the i/o operations or paging?
4)Can I do the shrinking of the log files alone without the shrinking of the corresponding data files?
SQL2005 Cannot Backup A Restored SQL2000 Database With Unknow Database Full-text Catalog Database
Nov 15, 2007
We replicate a SQL2000 database (DataBaseA) to a SQL2000 database (DataBaseB) by using the Restore function and hasn't change its logical name but only the physical data path and file name. It is running fine for a year. We use the same way to migrate the DataBaseB to a new SQL2005 server with the Restore function and the daily operation is running perfect. However, when we do the Backup of DatabaseB in the SQL2005, it just prompt the error message
System.Data.SqlClient.SqlError: The backup of full-text catalog 'DataBaseA' is not permitted because it is not online. Check errorlog file for the reason that full-text catalog became offline and bring it online. Or BACKUP can be performed by using the FILEGROUP or FILE clauses to restrict the selection to include only online data. (Microsoft.SqlServer.Smo)
Please note we left the DataBaseA in the old SQL2000 server.
Please help on how we can delete the Full-text catalog from DatabaseB so we can do a backup
Many Thanks

I downloaded and ran AdventureWorks.msi into my SQL Server Management Studio Express (SSMSE) one year ago.But I did not know how to attach it to my SSMSE then. Last week, I deleted it from the "Add or Remove" of Control Panel and I downloaded the new AdventureWork.msi and installed it my SSMSE.

I clicked on AdventureWorks.mdf and I got the following error: One or more files do not match the primary of the database.

The ASPNETDB.MDF was shown in App_Data and Database Explorer, but not in the SQL Server Management Studio Express. The AdoStepBy Step database created by a ConfigDB.exe was displayed in the Management Studio, but not in the App_Data, or Database Explorer.
Is this the way SQL Server 2005 runs the 2005 databases for SQL Server 2005 Express only? Or also in SQL Server 2005?

View 6 Replies View RelatedIntegration Services :: Import Varying Number Of Tables Each Time From One Database To Different Database
Sep 9, 2015I am new to SSIS. I have been struggling with this for the past one week. I have a weird task. I need to import several tables from one database to a different server with a new database name. We need to do this at the end of every year. The main problem here is that the number of tables varies every year. You may not have all the tables as last year or may have more tables. So I need to create a dynamic task that takes care of this every year without changing the package.
I have performed the following tasks **
1. Create a new dynamic database. ( I have used Execute SQL Task to do this) 2. Copy all the table structures ( I have used Execute SQL Task to do this)
3. Import Data. This is the main problem. I was trying to create a dynamic connection string with variables as suggested in several forums but I finally came to know that this cannot be done if the table structures are different as the metadata cannot be refreshed at runtime.
4. The final step to create a process to validate the data (the count from each table for both source and destination. I think this can be done with Sql task.
What is the best method to do this? My DBA does not like “Transfer SQL Objects Task” or “transfer Database Task”. I would like to create this as a dynamic process.
Migrating From Sql2000 MSDE Database To Sql2005 Express - Attach Database Errors
Apr 23, 2006I have a medical records system, SoapWare v4.90, that uses MSDE (SQL2000) databases. Due to the 2gb limitation, I am trying to migrate over to SQL 2005 (Standard or Express) which I have heard works fine. The SoapWare has a datamanager that allows me to log in to the MSDE instance, detach the SoapWare databases from msde (as well as do backups, etc) which I can confirm are detached.
Then I log back into a SQL2005 database instance using the datamanager and try to attach the database. This is what their pictured instructions demonstrate. However, I get the following error:
Database 'sw_charts' cannot be upgraded because it is read-only or has read-only files. Make the database or files writeable, and rerun recovery.
Of course, some of the entries will be read only, since doctors have to sign off the charts and are not allowed to subsequently change them. But I should still be able to switch over to sql 2005?!?!?!?
Or... is there a way to attach the databases to SQLExpress manually?
Help pls?

Feb 12, 2008Using SQL Server Express 2005, I have two databases. AppDB - The main application database.GeoDB - A somewhat static ZIP code / states / other geographic stuff databaseI need to have some foreign key columns in tables in AppDB reference columns in the GeoDB database tables. Eventually other application database besides AppDB will be doing the same thing in our infrastructure. After googling and reading for days, here is what I
think I know:You cannot create foreign keys that reference tables in another database in SQL Server.You
cannot create foreign keys that reference columns in a view, and you definitely cannot make an index on a view that has base tables in another database.You can create a trigger that references tables in another database, but this can be flaky? (nested/recursive trigger problem).SQLServer
2005 supports multiple schemas within the same database. Maybe I should logically separate my databases this way? Seems like it would be a tough solution to manage since I already have some databases live in production that will eventually use this 'static' GeoDB. Also, seems like it
wouldn't be as portable as keeping the GeoDB info in its own database,
but maybe I'm being too software engineer-ish here - afraid of low
cohesion, high coupling.I will greatly appreciate any advice I can get, or any more options I am missing. Thanks,Adam Nofsingerucnmedia.com

I would like to capture a success message if possible.I can extract the physical device name of the database in question using the following code:
SELECT physical_device_name, *
FROM msdb.dbo.backupmediafamily
WHERE media_set_id =(SELECT TOP 1 media_set_id
FROM msdb.dbo.backupset
WHERE database_name='MyDatabase'
AND type='D'
ORDER BY backup_start_date DESC)
I would like if the newly restored database was rename to something different than 'MyDatabase' (as shown above) and has different logs than the original. If possible, and capture a success message when restored.
