Query takes 1.5 minutes from SQL but more than 1 hour from application
We have one query which used by users to pull the report everyday in the morning. Which, i generally run through SQL and it takes only 1 to 2 minutes but it takes forever for users to pull the report from application.Statistics are updated and indexes seems looks good too. Is there anything else i can do run the query faster?

dynamic sql performance and implementation recs?
I'm working on a new service that will need to provide reporting data for regions. Each region will have its own db table and each db table will have some columns with the same name like ReportDate. The different tables will have a lot of different/unique columns which is why I created a separate table for each region. There will be about 10 region tables.I'm considering using dynamic sql for my sproc so I can write a simple query and then run it generically against each table. This would be much quicker and easier to write and maintain then writing 10 separate queries that perform the same SQL against all tables.Is SS pretty well optimized to handle this type of implementation? Do you see any potential performance issues? Are there any specific steps I should take to optimize performance for this implmentation? Does anyone here think dynamic sql is "evil" for one reason or another? I'm referring specifically to dynamic sql completely done within SS as opposed to an external app passing in dynamic sql statements.

Random Unique Number Always
Hello, I have a stored procedure that will be executing on a recurring basis at different intervals. There is a field that I need to populate with a random unique number but once I use one, I can never use it again. As this procedure will be called all the time and not just once, how do I ensure that I never use the same random number?I was generating it with this code: (SELECT FLOOR(RAND()*(100000-1)+1))But, it occurred to me that there is a small possibility that it could somehow pick the same number as a previous call to the stored procedure? Do I need to actually store the ID somewhere and tell it not to use one that already exists?Thanks!

The transient database snapshot for database 'DB1' (database ID 5) has been marked suspect due to an IO operation failure.
I have looked all over google regarding 'snapshots' in SQL 2008 and I have been reading up on their function and how they are created and removed as well as where you can review them from SSMS...I have NOT found anything of relevance regarding the actual error message. I did find a couple blog posts regarding the error message and DiskKeepper 2010 but that doesn't apply to my situation.We have an SAP instance that has several different kind of landscapes, on the particular server in question there is a lot of activity during the period of a DBCC check being performed.A lot of Disc I/O is generated...sometimes we get the error message in the subject. Additional executions of the DBCC even when nothing is running will fail.once the server is rebooted and the DBCC is started again then it works just fine.I am curious if someone has a different view point on the error listed above.The error is occurring on a SQL 2008 x64 enterprise edition hosted on windows 2008 enterprise. The servers are all virtual servers on an EMC sanAny discussion is appreciated.Thanks,Lee

Lock level
Dear all,I have some stored procedures that I was calling one by one and passing a variable with the market code. All using the same connection.Like 1 - Open connection. 2- Execute sp1. 3 - Execute sp2 ....(those are 7 stored procedures)Now a new team started to trigger this but instead of triggering 1 by 1 till the seven finish, they are doing the opposite. They are executing 5 times the same stored procedure in parallel , each one with a sifferent parameter.This is taking a lot of time. it seems we have several locks (not deadlocks).I know that I can decrease the isolation level inside stored procedures so that they don't cause locking.What is the lowest level ?Also, when the stored proc ends, the isolation level gets to its normal state?thank you

New 2008 R2 Installation Errors
I have a freshly installed SQL Server and I keep getting the same error on some of the actions I attempt. When I right click a database and go to Tasks > Import Data and when I right click a table and go to delete, I get the following error:"Cannot show requested dialog. Additional information: Could not load file or assembly 'Microsoft.SqlServer.Sqm, Version = 10.0.0.0, Culture = neutral, PublicKeyToken = 89845cd8080cc91' or one of it's dependencies. The system cannot find the file specified. (SqlMgmt)"I tried to go through this with my clients DBA but he told me to copy the file from the Program Files into two directories and then register them (the above .dll) but they won't register. He got frustrated and gave up on me. Any ideas?

Blocked Process Alert issues
This is really beginning to annoy me.I have Blocked Process Alerts on every single server in our environment. The alerts are set to email us when the blocked processes get above 2. So what happens? Our DEV server (not Production, not any of the others) is constantly sending emails out about the blocked processes. I finally got annoyed and set up a job to try and catch the blocked processes (runs every 3 minutes). The problem is, the job isn't catching the events that trigger the alerts. In fact, it's catching other blocking events that don't trigger the alerts. I'm about at my wits end.Does anyone have any suggestions on code that can assist me with catching whatever is causing the alerts?The code I'm using I got from Ian Stirk's website / blog. It's attached for reference if you want to see it.

sqlcmd adding/modifying date to filename
We're using the SQLCMD command to extract content from a database and place into an output file. Set that up and it works fine. Then a date was attached to the output file name - that works fine. Last effort to subtract one day from the date and we're stuck.This is what we've tried so far:sqlcmd -S server -d database -E -W -w 900 -s "," -i F:\query-location.sql -o F:\output-file.csv -- this works.Then added the date:sqlcmd -S server -d database -E -W -w 900 -s "," -i F:\query-location.sql -o "F:\output-file$(ESCAPE_NONE(DATE)).csv" -- this works as wellNow the problem area:sqlcmd -S server -d database -E -W -w 900 -s "," -i F:\query-location.sql -o F:\\output-file$(ESCAPE_NONE(select cast (GETDATE() - 1 as DATE)).csv -- this kicks out a syntax error. Is there syntax to do this without using xp_cmdshell or powershell? Googling this we found an article suggesting xp_cmdshell. While that looks like it will work - don't know if that's the route to go. Any comments / syntax recommendations / URLs would be appreciated.Thank you.

SQL Agent CmdExec fails with no message

The step failed.[/quote]I know that the path is correct because if I change it, then it tells me that it can't find the file. The cmdexec looks like this:\\share\path\TheProgram.exeThe program is a console application developed in .NET. The console application runs successfully if started outside SQL Agent. This program is replacing an existing program (which was also a console application) that had been running via the same job successfully. While the program displays data to the console (data which is also logged elsewhere), it does not require any input from the console. I don't care if the console is visible. It's a long-running application, so it should leave the job in a running state, not in an immediate failure state.To add complication to this scenario, the server on which this is running was recently replaced. All software was reinstalled and the database was restored. So it's possible that any special configuration that was done to allow SQL Agent to run this job was lost. The knowledge of that configuration, if any, was lost years ago when the initial developer left.The application should be logging, but it appears the error, whatever it is, occurs before the app starts. The very first thing this application does in main is to log that it's been started.If only I had an error message to work with...Ideas?
