Check For Database
May 6, 2008
Hello,
I am performing a number of queries on a database and inputting the results of those queries into a target database.
These queries are performed inside a number of data flows.
I would like to do two things:
1) Check that the target database can be seen before entering the dataflows. If not, wait X minutes and then retry.
2) If, for some reason, SSIS loses connectivity to the target database during the process, I would like to, is possible, roll back any current transactions and start over.
Unfortunately my knowledge of SSIS is very limited, so if anyone could lend a hand I would appreciate it.
Best regards,
Simon

I was wondering if it was possible to check what server database you are currently connected to, using T-SQL, when executing commands in Query Analyzer. Even though you choose the server and database when connection, sometimes by habit you may connect to the wrong server & DB, and execute an .SQL file. Is it possible to put a line of T-SQL at the beginning that performs this pseudo-code, as a safety feature:-- While in Query Analyzer with a certain .SQL file open:If current server <> 'TheCorrectServer' and current DB <> 'TheCorrectDB' then cancel this .SQL file execution.

Hi everyone,
I am looking for a way to check to see if a database is a snapshot or not. You can for example check different properties of a database by running the following:
SELECT DATABASEPROPERTYEX('databasename','Recovery')
SELECT DATABASEPROPERTYEX('databasename','IsInStandBy')
SELECT DATABASEPROPERTYEX('databasename','Status')
So I am trying to see if there is a way to check for a snapshot
Thanks,
Reghardt

Hi,
I'm wondering is there a command that I can use to check if a certain value exists in the database? Something that returns true or false perhaps?
SELECT * FROM Customers WHERE ID ='1'
Ok so that's simple, but how can I return a true or false if '1' is a value that exists in the db?
thanks.

I want to query my databases to find out if Auto Shrink is set. I know the status column in sysdatabases holds this value as a bit setting but I don't know how can I check this value using a query.

Hi,
I have no way to test this. If let's say the database has logical integrity errors, will it throw back an error to the Check database integrity object such that, the error arrow (the red line which is the error handler stuff) will be triggered for notification purposes?

How can I check if the database is currently being backed up?
Seems like that should be a property, but it's not an attribute of the DATABASEPROPERTY function.

shrinking the log as it is unnecessary IO to the disk.
How often is the check database integrity scheduled. is it daily or weekly.

Hi
I am working at a site that has no dedicated DBA, and our Sql Server 2000 environment has recently been playing up. There are several databases on the Production server that should be inactive (for applications no longer used).
What is the best way for me to see if there has been any recent activity on these databases (short of taking them offline and waiting for screams). Please keep in mind that I am a Sql Server novice.
Cheers

I have a database hosted that doesnt passes the integrity test. Here is the error it gives :
Executing the query "USE [db_cs]
failed with the following error: "Could not locate entry in sysdatabases for database 'db_cs'. No entry found with that name. Make sure that the name is entered correctly.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
Any idea whats wrong and how I can let the integrity test pass for this db.
Thanks,

I allow the user to delete record1 from SQL Table1 and record2 from Table2. The only problem is, record1 and record2 refers to record3 in Table3 and I can´t allow the user to delete record1 if the is a field in record3 with record1 ref. code. I can´t set FK between them cuz there is more than one reference to the same field.
Can someone point the best solution for my problem?

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.

Is there anyway to check for cross-database dependencies?
For example:
I have a stored proc in the Pubs database that contains a query that references a table in the Northwind database (as well as reference a table in the Pubs database.) I'm having no problems finding the depencency for the Pubs table. I can't seem to find the dependency for the Northwind table.
Any help would be appreciated.
Thanks in advance.

I have setup a full maintenance plan on SQL2005. When I run the job, I don't see any error but by loooking at the Log file viewer it appears that Check Database Integrity step failed because :
Alter failed for Server 'LUMONT001'.
Moreover, when I run DBCC CHECKDB from the console I have no error message. Any clue?
Thanks, Paul

Hello everyone! Looking for some insight here on database backups that fail.
We have many SQL servers that we maintain by storing Job/Maintenence Plan history on a central server, which then emails out daily reports to let us know what backed up last night and what didn't
This was easy to do in SQL 2000, not so much in SQL 2005. I have put together a query that gathers the info I need for the successes:
SELECT DISTINCT '00000000-0000-0000-0000-000000000001' AS Plan_ID, mpld.line1 as "Plan Name", bud.database_name as "Database", mpld.server_name, 'Backup Database' as Activity, mpld.succeeded, bs.backup_finish_date, DATEDIFF (MS,bs.backup_start_date,bs.backup_finish_date) as Duration, bs.backup_start_date, mpld.error_number, mpld.error_messageFROM msdb.dbo.sysmaintplan_logdetail mpld
INNER JOIN msdb.dbo.backupset bs
on (select convert(char(12),mpld.start_time,109))=(select convert(char(12),bs.backup_start_date,109))-- on bs.database_name=bud.database_name
inner join
msdb.dbo.bu_dbs bud
on bs.database_name = bud.database_name
WHERE mpld.succeeded = 1 and mpld.line2 like 'Backup%' and bs.type='d'
and bs.backup_start_date > ( SELECT CONVERT(char(12), (GETDATE()-1), 109) )
ORDER BY bud.database_name DESC
But I am having trouble using a query to determine the databases the FAILED during backup. MSDB.BackupSet and MSDB.SYSMaintPlan_LogDetail really have nothing,because often times, even if a step in a Maint. Plan fails, the plan finishes reporting success.
Does anyone know of a good way to gather info about failed database backups?
Thank you!
Mario

I want to run Profiler Traces, Perfmon Checks and whatever else to see what hits the server the hardest in order to work out where I can make performance improvements. We don't have any massive problems other than more timeouts than I would expect from web users no-and-then when they do pretty simple free-text searches. I just want to see if I can lighten the load on the server in general.
Where does a DBA get the most ROI? I don't want to drift into the realm of diminishing returns where I am making changes that have no noticeable impact.
What should I start measuring first and how do you measure it? (E.g. if I should monitor disk writes in Profiler, how many writes are too high for a statement? 100? If so, is one 100-write statement per hour OK but one 100-write statement per second is not OK?)
If there is already an article for this, my apologies. I'd be grateful if you can point me to it.
Is http://www.sql-server-performance.com/ a sufficient one-stop-shop for this question? If so, have you found some articles there to be more useful than others?
