Question: i have to do an update on a table that has a nested index of three fields. however i'm only getting one field as a parameter to work with and i am getting a constraint because there cannot be duplicate records.
Is there a way to only do the update code if the unique key constraint is not thrown? i was thinking about doing this in an if statement but the problem is i do not have all three keys that i can use to do the right query. thanks
Hi!
I have created a formview which I among other things uses to insert new values into a database. What I want to check is if the primary key which is put into the form already exists in the db. If it is I want to get a message to my web page, if not the data can be inserted.
How can I do this?
And if the only way to control this is to create a stored procedure. How do I write such a proc?
Hi,
Can someone please tell me the best practices for checking the primary key field before inserting a record into my database?
As an example I have created an asp.net page using VB with an SQL server database. The web page will just insert two fields into a table (Name & Surname into the Names table). The primary key or the Names table is "Name". When I click the Submit button I would like to check to ensure there is not a duplicate primary key. If there is return a user friendly message i.e. A record already exisits, if there no duplicate, add the record.
I guess I could use try, catch within the .APSX page or would a stored procedure be better?
Thanks

Hello all.
OK i have script which is to be run on several databases. Within this script there are commands to create a primary key on a specific table. Can anyone tell me if it is possible to check if a specific primary key exists on a table?
Thanks people.
I have a server that has several DBs .. some are log shipping(ls_) and others are not. The current TRAN backup script just does a:
select name from sys.databases
where name != 'ls_xxxx'
and name != 'ls_yyyyy'
Is there a way to check a status byte or something so I can remove the hard coded names?
select name from sys.sysdatabase
where status = 'I log ship' -- ;)
I checked several places, but found nothing. Finding other status like RECOVERING et al ... is easy
Hi all,
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. Today, I tried to use the Database Explorer of VB 2005 Express for the first Stored Procedure programming. I clicked on AdventureWorks.mdf and I got the following error: One or more files do not match the primary of the database. If you are attempting to attach a database, retry the operation with the correct files. If this is an existing database, the file may be corrupt and should be restored from a backup. Cannot open user default database. Login failed. Login failed for user 'CENADe1enxshc'. Log file 'C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataAdventureWorks_Data_log.ldf' does not match the primary file. It may be from a different database of the log may have been rebuilt previously. Please help and advise me how to correct this problem.
Thanks,

View 4 Replies View RelatedHi, I have a Users table that I use for membership. Now I am using username varchar(30) as the primary key for this table since username will always be unique.I am storing username in UsersInRole table so that I can find what roles each user has.The question I have is regarding how SQL Server actually stores data:I see that when I add users, they are always stored alphabetically sorted on username. I was expecting that all users will appear on the users table in the order they were added.Example: I have 3 users (john, jonah, wilson). Now I added 4 user with username='bob'If I execute select * from users, it returns me (bob, john, jonah, wilson). Look bob is has become the first row of the table.My question: Is Sql server moving 3 older rows to make room for 'bob' and it is also rebuilding part of the index due this new username 'bob'?If this is the case, then it will have big impact if I have 100K users and I add one user that becomes firstrow. In that case huge other rows will have to move.Bottom line, insert, delete will be expensive. I know sql server keeps data physically sorted on PK. But I am concerned here since rows are losing the order in which they were inserted.Thanks
View 8 Replies View RelatedI would like to do partitioning one of my client, but that primary database is participating in log shipping.
If I do partitioning on primary, automatically apply those changes on secondary db? if not, what is the way?
Note: I am adding new filegroups and ndf file in different drives on primary database.
Hi !
How do I check when my database was last used ? I have two old databases that I think is not in use, but I want to check to make sure before I delete them or take them "offline".

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.

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,

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.
Thanks
what does check database integrity in maintenance plan do.
i heard that the transactional log growth in sql server should be fixed to maximum available disk space and must be monitore the threshold through maintenance plan.how can it be done. please advice me through maintance plan instead of
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,
