Restrict Deletion
What would be the best practice to prevent users who didn't create a record in sql from deleting? When a record is created I have the username who created the record in one of the fields. I was thinking maybe a query?
 
Thank you in advance.

Replication Without Deletion
Hello there,

We are currently setting up out production server to the following requirements:

1. Every month, delete records that haven't been changed in the last 90 days.
2. Replicate insert statements to a backup database which will keep track of all data, and act as an archive/data warehouse.

The first step is easy, as it is just a script that checks the date of the last change on each row. However, the second step is a bit more tricky. We tried setting up replication between two test databases, but we ran into the following problem: Whenever old data has been deleted in the production database, the replication agent deletes it in the data warehouse database too.

Is it possible to override or disable this, so data is only inserted/updated, and not deleted? No applications using the database deletes records, so database integrity should not be a problem.


Thanks for your time,

Ulrik Rasmussen

Deletion Problem
It is an option to set deletion without getting logged since I have problem to delete two years historical data and would like to keep this year data on my 80MB rows. Actually I create a new table to get copy one-year data and I truncated the old table. I am wondering if there is other better way to do this task.

TIA,

Deletion Query
Ok, so I have an issue, was wondering if anybody else has any suggestions.

I have a table that is pretty large, in all regards.  It is a "message" table that holds text messages that users send to each other.

1.  Has some data fields, integers, dates, some bit columns, a message subject field (varchar(250)), and a message body field (field type = text)
2.  Table contains about 70 million records
3.  Table has 6 indexes associated to it
4.  Table has 2 views associated to it.
5.  Table has 8 foreign keys associated to it.

I need to delete, oh, about 90,000 records out of this 70 million record table.  I am able to disable the foreign keys to this table for deletion, but that does not seem to mitigate the problem.  I think the issue lies with having to update the indexes as well as the views.

When I execute the select statement to retrieve the records I need to delete, it executes pretty quickly, no problems there that I can see.

The issue comes when I try to delete the records, it takes way too long, and we know it.  We let it run for an hour and it didn't really get anywhere.  This is in a server environment, some pretty decent hardware, 8gig memory, fast SCSI drives, 8 core processors, i don't know the exact specifics, but they're not bad.

Here's a DBCC SHOWCONTIG on our table

DBCC SHOWCONTIG scanning 'message' table...
Table: 'message' (1448040590); index ID: 1, database ID: 13
TABLE level scan performed.
- Pages Scanned................................: 51602
- Extents Scanned..............................: 6486
- Extent Switches..............................: 6948
- Avg. Pages per Extent........................: 8.0
- Scan Density [Best Count:Actual Count].......: 92.83% [6451:6949]
- Logical Scan Fragmentation ..................: 0.54%
- Extent Scan Fragmentation ...................: 0.93%
- Avg. Bytes Free per Page.....................: 93.5
- Avg. Page Density (full).....................: 98.85%
DBCC execution completed. If DBCC printed error messages, contact your system administrator.

This is from our dev environment which is but a portion of our production db- but I presume our production environment will have similar percentages (not necessarily the pages scanned)

Any suggestions on how to delete records efficiently?

How To Prevent Db Deletion
Hi

I want to try and protect myself from my own stupidity. I have a number of sql databases, but one is LIVE. It is easy to drop tables but I want to set something (e.g. a password) which will help prevent me from dropping tables on the live database.

Any help/direction here would be appreciated.

Database Deletion
While performing import actions I had a system freeze, when the system returned the sessions had been closed and the database had vanished, with the help of support we recovered the database only to find that the original project ID had a suffix attached ( Original 40/0110, New 40/0110-1 ), when I try to return it to it's original numbering convention it says it has to be a unique number which suggests to me it is not deleted but hiding in the background, can the original be recovered or is it possible to renumber the recovered database, I have searched the whole of the databases and the original is nowhere to be seen.

Deletion And Identity Reset
Obviously to delete all records from DB table is simple, however, I would like to make my whole Live DB pretty much empty.  I've copied all my data from my test DB over to my live DB (didn't mean to but I did).  I would like to remove all the data and the identity values, resetting them back at their original values.  Is there a simple way or do I have to do it the hard way.  That being going in and removing Identity, saving and then placing identity back on the DB Table.

Alert On Data Deletion
We have an employee table that contains bank details and are experiencingproblems with account numbers being erased and lost. In order to track downwhy this is happening (either due to our application code or SQLreplication) we'd like to be able to prevent certain columns from beingdeleted if they already contain some data.Is it possible to setup a check constraint to prevent our ee_acct_no columnsfrom being set to NULL or blank strings if it contains an account number(i.e a 9 digit number)? We have setup the column to allow NULL's as we don'talways know employees bank details until later, so we do need to put them onour database without bank details initially.Also, if possible, can someone suggest a stored procedure or trigger i couldcreate that would fire a user-defined error message that would email anoperator if a bank account number changed?Many thanksDan Williams.

Database Still 'exists' After Deletion

Basically, I create a database with sql, then I delete it manually(not via sql statment. This is a problem which I realise. In fact, you can't delete the database because the VS 2005 still is using it) I run the same code again,

Daily Deletion Of Records
Ladys, Gentlement, I have table that grows anywhere from 200,000 to 1,000,000 records perday. Besides that I need to keep at least 6 months historical data from this same table. The transaction log was purged after each batch when testing data monthly. I'm looking for some way of deleting just one day's data if it meets a criteria. It must remain within the 6 months period of historical data. This is what I've come up with so far"

select * FROM dbo.Temp_table WHERE datediff(day, DATE_TIME, getdate()) >= 180

If it meets this criteria I can change the select to a delete? Please Let me know what you think

Auto Deletion Of Records Sqlserver
 Hi I am not sure if I am at right place, anyhow I hope I am :) Now the question: I am using an ASP.net Application with SQL-Server. I want to make a page so that it set the expiration time (date)  for certain record and once that time reaches, it deletes those records, or make any updates to the record (what ever applicable). I also want to control this auto deletion from my application, means that turn this On/Off whenever needed. I am not sure how to start this. I was told by a friend that I need to use triggers from SQL-server but I need some help. Can anyone help me out on this? RegardsMykhan

Deletion Old Data In Replication Environment
Hi to allI have a question about deletion of amount of data:My production environment is this one:- one publisher with a database (historycal events)- 50 subscribers with the prev database in unidirectional replicationunidirectional (from subscribers to publisher)My target was capturing events from the subscribers to send them topublisher (later I can do reports on it).Once the data is on the server i don't need them any more in subscribers.Now I would like to delete the oldest data (year 2003) of some table on thepublisher (remember that replication is unidirectional S->P).The tables contain about 6-7 millions of records.I delete one month per time. The process is about 30 minutes long and themerge agent subscribers changes in retry state.Can I use these queries to make faster this process? Eventually what kind ofproblems can I have ?DELETE FROM mydb WITH (PAGLOCK) WHERE mydb.dbo.mydate Between date1 anddate2orDELETE FROM mydb WITH (ROWLOCK) WHERE mydb.dbo.mydate Between date1 anddate2Thank you very much for your support.Marco

SSIS Crash On Breakpoint Deletion
I'm having an issue with trying to delete breakpoints in my SSIS package.  I think the breakpoints were created when I added dataviewers through my process, however the breakpoints were not deleted when I removed the dataviewers.  It would then appear that my process would not halt on ANY breakpoints - orphaned or valid. 
 
Furthermore, whenever I tried deleting the breakpoints manually, my whole IDE would crash.  I got around the issue by closing the dtsx page first, then deleting the breakpoints, and reopening my dtsx. 
 
Are these valid bugs with SSIS?  Has anyone else experienced this?  I'm running this against a SQL Server 2005 database using VStudio 2005 as an IDE.
 
Thanks!

Deletion/Rename Of Master Database.
Hi All,

Can we have an sql server installation where we dont have a master database. Can the complete data dictionary be stored in another database , or put it other way can master database be renamed.

I have a need to assume that there will always be a master database for any SQL server instance. Want to confirm whether this assumption is true or not.

Thanks in advance.

Unique Columns And Logical Deletion
In tables where reporting or historical information needs to be maintained I find that logical deletion of rows is better than actually deleting the row and any FK relationships.  However when one of the columns in the table must be unique this introduces a problem because uniqueness only matters for "active" rows.  I'm hoping someone can provide some advice on how to best handle this situation.

 

Here is an example to work from.  Suppose we have a table that contains job positions.  The table contains an IDENTITY column for the PK (to avoid duplicating position names), a Name column that must be unique and an IsActive column that is set to 0 when the position has been "deleted".  This setup allows for historical reporting to properly pick up the position information even though it might no longer be used in a company.  You can substitute your own scenarios here as there are quite a few.

 

Now if the Name column is marked as a unique column then the DB will enforce integrity which is what we want.  However we will want to be able to "delete" a position but later add a new position with the same name.  One could argue that we should just "undelete" the original position but that is not often a good idea so assume "undelete" is not an option.  Given the unique constraint a new position could not be created if an existing position (active or otherwise) already existed with the same name.  We could set up the unique constraint to include the Name and IsActive columns but now we are prevented from ever deleting two positions with the same name.

 

My initial thought is to create a new UniqueName column that is unique and remove the uniqueness constraint on the Name column.  The UniqueName column is set (via a trigger) to the Name column when the position is active.  When the position is deleted the trigger changes the UniqueName to include a timestamp or something to ensure uniqueness.  This is handled by the system and not exposed to clients.

 

Any advice or alternatives on this approach (preferably with advantages and disadvantages)?  Thanks.

MS SQL Server 7: Deletion Of Child Records.
Hello All,

I have been involved in a project wherein i have to delete old records from two table and the corresponding child records from the interlinked tables.
I try to find a SQL Procedure that deletes the child records, but that procedure uses the sysforeignkeys table for recursively deleting the child records.
When i looked at my sysoreignkeys table, it was empty(no rows).
Request you all if you can provide me the SQL Procedure that can delete record in the table with the child records.

Thanks in advance

Regards,
Manoj Kumar

Distributed Transaction Completed. Either Enlist This Session In A New Transaction Or The NULL Transaction.
Hi all, I've already read the thread by the same topic, but I found Kevin Yu's comment a bit confusing.  I don't know how to solve my problem.  I have two stored procedures in sql server.  First one inserts into a bunch of tables so it has Begin Transaction and Commit in it.  Second one just inserts into one table so it doesn't have the begin transaction statement in it. From my data access class in c#.net, I have a function which calls both of these stored procedures from within a "using transactionscope" block.  So when it makes the call to the first stored procedure, it returns fine, but when it calls the second one, I get the above error.   I think it has something to do with me declaring transactionscope in my application code, and then calling a stored procedure which also has its own begin transaction.  But I don't know how to fix this.  Any ideas? Thanks

Distributed Transaction Completed. Either Enlist This Session In A New Transaction Or The NULL Transaction
I'm using TransactionScope object and it is giving me problems. The situation is like this.
I've 2 tables in sql server express, say student and courses and other one studentcourse for courses a student has opted for.
An aspx page displays list of users in listbox, when user chooses student, it fetches courses he has opted for and in the checkedlistbox (for courses) these courses are checked. Now when uses makes any changes to courses and clicks update button, i've
two functions at backend first one removes the courses which were previously selected but now not selected in postback, next it inserts courses which was not selected first but now are in this postback.
I use following code:

protected void Update(object sender, EventArgs e)
{
/*
get selections, existing courses etc.
*/
using(TransactionScope tscope=new TransactionScope())
{
try
{
RemoveCourses(/*Student*/ s, /*IList*/ oldCourses, /*IList*/ newCourses);
AddCourses(/*Student*/ s, /*IList*/ oldCourses, /*IList*/ newCourses);
tscope.Complete();
}
catch(Exception ex)
{
lblMessage.Text=ex.Message;
}
}
}

If any exception occurs during update and page is reload or I go to any other page where some data is fetched from sql server I get the exception:
Distributed transaction completed. Either enlist this session in a new transaction or the NULL transaction

Please help!

Help - Recovering A Deleted Job
Any ideas how I can recover a job that has been deleted (?) from SQL7.0 ? We had one which was used on a regular basis which has nowceased to exists. I've spoken to the people responsible for the serverand was met by blank faces (as usual). They have no idea when it wasdeleted, by whom or when. To make matters worse, they don't think theycan get it off the backup set without a major bit of work to theserver. Suprisingly, none of the users noticed that things had stoppedworking.Unfortunately, I needed to do some work on this in preparation for mymonthly meeting with my boss on Monday. Whilst I'm not to blame, I'dlike to understand a little more about any options available to us forrecovery as he will undoubtedly ask when he finds out.I have an old back up on another server, so it's not the end of theworld re-creating it, but I was under the impression it was backed upproperly. Is this normal or have they missed something ?Are there any ways I can recover this ? What can I get done to thebackup to make sure this is backed up properly ?Thanks in advance.Ryan

Recovering Database With Nothing But .DAT
I need to recover a database, but unfortunatelly i don´t have any backup... Well, it was not my fault. Anyway, i only have the physical .DAT files of the data and log devices of the database.
Will it work if I create two devices with the same name as the old devices, create a database with the same name as the old database within these devices and then run a full script of my old database, then change the 'phy_name' on the sysdevices to point to where my old dats were, or replacing the current ones with the old ones? If not, will anything else work?

Thanks in advance.

Recovering Msdb
Hi, I am in the process of writing some backup and recovery procedures for
our SQL Server system and have run into the following problem:

I have been testing the recovery of the msdb database and have had
no luck recovering the full database.

To test the full backup and recovery, I have performed a backup of the msdb database, made
a change (ie. add a task) and then performed an incremental backup.

Following this, I will manually delete the database or shutdown the server and rename
the msdb data device.

I am able to recreate the database and load the database dump, but upon trying
to load the transaction log, I get an error saying that the transaction log dump is out
of sequence. Restart from initial load. This error continues to occur and I have repeated
this process many times.

I was able to restore this database (database dump and transaction log) to another database
named 'test' and then rename it to 'msdb' . This is the only way I have been
able to sucessfully recreate the full msdb database.

I have not been able to find any documentation regarding this and was wondering
if there is a set of procedures around restoring the msdb database after a failure?

Thanks in Advance!

Help Recovering SQL 6.5 Server
I have a client who lost a SQL 6.5 server, all they have is a backup of the Log and data files. The don't have any db dumps.

The reinstalled NT & SQL, so their is nothing on the server of much use.

If we were to use Disk ReInit, this will I think reattach the devices, but what about the DB? What do I do next?

Thanks
