Can any one recommend an approach for identifying the frequently accessed tables and files in a SQL/Server application? Particularly, if the database is stored on raw partitions instead of FAT or NTFS. Thanks.
View 3 RepliesI'm working on databases where statistics of some indexes (tables) are changing too frequently. Once I update them manually, one minute after they get 10-20% change, and five minutes after they get over 100% change. Tables get updated very frequently (multiple times in a second).
When I run a query to read from sys.stats, sys.dm_db_stats_properties and other dynamic views, I see that they were last updated when I did it manually, but the change rate overpassed the 500+20% (tables have multiples of 10K rows). Auto create and update statistics are set to true on all databases, and I don't know why sql server does not do that automatically.
I want to know howmany tables were accessed in a database from time A to B. How do I get the list of tables accessed (excluding the 'SELECT's)?
View 3 Replies View RelatedI have inherited support for a database with many used tables. Thereisn't any documentation on what is used or dead. I was hoping to runtraces and capture the objectid but the property doesn't work thatway.Any good ideas would be appreciated.

But it doesn't explicitly tell wherther Interpreted (disk-based) tables can be accessed by Natively compiled stored procedures.And SQL Server Express edition doesn't allow creating Memory-optimized objects to very this.
View 2 Replies View RelatedI have a query that retrieves a single record from searching on two tables.
The statement goes like this...
select sum(amount) from Table1 A union Table2 B on a.id = b.id
where date < ### and date > #### and account = ###
As people are running a particular report, this statement is executed time and
time again to pull up the numbers necesarry for the report. When the report gets slow, I can speed it up by updating the statistics. My concern is that I'm having to update the statistcs every hour; otherwise, the query becomes slow. I have noticed that users are inserting data while users are running the report on one of the tables listed above. I'm sure that's making it become more fragmented and ultimately slowing down the query.
Do you have any suggestion on how I can make the union of these two tables faster? Or is there anything I could do to speed the query besides creating clusted indexes?
Any help would be appreciated....thank you
Hi Everybody:
We have a table which needs to be updated 2 million times per day. It hosts all real time transaction. There are 200K records in this table. Would you please to share your experience with me about how to protect/save such table in SQL 2000 from any possible damage?
We plan to use point-in-time backup (every 5 minutes). It still takes at half an hour to recover the whole database. Any new technology from Microsoft or SQL 2000 you can recommend?
Thank you very much.

I use SQL2005 EE to capture the "In Progress Data" from the Devices and have connected it to the Main server-SQL2005 SE thro linked Server. I Run a Job that updates the Main server and Clears the "in Process Data".
Off late I have been seeing that the systems with SQL2005 EE have gone slow ? I have not investigated the reason. But wanted to find out if using this method ,should I need to take additional precautions ?

What is a Yak? 07May2007
Hey guys. I need a little help once again, here's the problem:
We are using an attendance system software that adds records in an Access 97 table whenever someone logs in or out of the room (Yes, it's old and I hate it, but it came with the hardware).
So we plan to create a program that lets admins check those login/logout data in an SQL Server 2005 database using a Visual Basic as the frontend.
Our only problem is, how do we transfer data from the Access 97 tables to our SQL tables *everytime* it gets updated? We don't need every detail the Access97 table has (it has IDNo, CardNo, Time, Location, plus other useless stuff). We just need to extract the IDNo(int) and Location(varchar) field(we'll just use getdate() for the Time since the update is done in realtime anyway).
So in a way, we are trying to find out a way to technically sync both tables, just like Database Mirroring style.
Any suggestions?
Hi,
In a project with SQL Servcer 2005 the customer is interested to save (archive) content of a table frequently. They want to have possibility to restore the table content as before. I have suggested to export the table every day to a text file and save the file in Visual source safe. If they need there will be possibility to import the text file later. Now I wonder, is there any other way to do archiving of the table content in SQL Server 2005?
Best regards

Hi guys,
I faced problem related to Locking and Isolation Level on Table(s).
My problems is there r some tables which r frequently updated, and I also want to fire select query over those tables every 1 seconds and want to get only committed records.
In current scenario we start transactions with ReadCommitted Lock for updating records. But in this scenario I can€™t get select query result because of some of recourses r used by transactions so after some time it gives Deadlock error.
So I want solution like both operation run simultaneously and get only committed records at a time of transaction running
Please help me for solving my problem.

We have some databases on old servers which we would like to discontinue but do not know if they are being used.

Hi,
I have trouble displaying images that are accessed through URLs in my report.
If I call the URL directly in the Browser the Image can be opened without problems.
The images can be accessed with an anonymous access.
When I deploy the report or in the Preview of Visual Studio I get the following message:
[rsWarningFetchingExternalImages] Images with external URL references will not display if the report is published to a report server without an UnattendedExecutionAccount or the target image(s) are not enabled for anonymous access.
In Layout View of Visual Studio the image is showen correctly.
The Images are stored on a Solaris maschine with WebSphere 6.0 as WebServer.
Any ideas?
Thank you.

I am trying to manage a sql server.
In this sql server, I have about 200 databases.
Is there any way/suggestions to check to see if some of the database has not been accessed/updated for the last month or longer?
I am trying to develop a system to remove the database that's no longer needed.
Thank you.
Is anyone aware of a method of determining when a table was last modified or accessed?
Some of our databases have tables that I am sure are not being used and I would like to generate a list of tables that have not been accessed or modified for some period of time.
I looked for a system procedure but didn't see anything that satisfied my need.
Currently I rename suspect tables and wait for someone or some process to gripe, but I don't care for that method for obvious reasons.
Thanks!
I was having issue with one of my databases in SQL EXPRESS. It is offline this morning …it said “Database 'MyDB' cannot be opened due to inaccessible files or insufficient memory or disk space. When I checked the error log ..it only said “FCB::Open failed: Could not open file D:DatabasesMyDB_Data.mdf for file number 1. OS error: 32(failed to retrieve text for this error. Reason: 15100).
I did alter database offline and and online ..it works for me( I can access the database again but I need to find the cause of this issue )I checked the max memory setting is still by default .. not limited for SQL ..it could be the cause ?

Hello,
I have recently started working on a OLAP application. The database is around 35 gig, with over half of that space being taken by the indexes. What has happened is previous developers have added indexes to attempt to improve the performance of a select statement (for reporting). Some of the indexes work, but many do not.
I would like to drop the ineffective indices. What I would like is a way to find if indexes are being used, preferably by object name. Is there a third party vendor that can monitor objects and how much they are used? Is there another way to do this using SQL?
Thanks in advance,
Jim
