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?
Regards

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

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.

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

Insertion And Deletion Of Records Inside A Single Stored Procedure
Hi, I have two tables A and B. In table A i have three columns called empid, empname and empsalary where empid is an identity column. Table A has some records filled in it. Table B has the same schema except the fact that the empid is not an identity column in table B. Table B does not contain any rows initially. All other aspects remain the same as that of table A. Now i am going to delete some records in table A based on the empid. When i delete the records in table A based on empid the deleted records should be inserted into table B with the same empid. I need to accomplish these two tasks in a single stored procedure. How to do it? I need the entire code for the stored procedure. Please help me. I am trying for the past 4 days. Thanx in Advance

Auto Insert A Variable Number Of Records?
I have the following situation; I have one table (tblA) in which a new record just has been inserted. Once this insert is completed successfully, I want to insert a variable number of records into another table (tblB). The primary key of tblA is being used inside tblB as one of the columns in each insert. I’ve already been able to transfer the primary key, generated by the insert for tblA, pretty easy. But to make things a bit more complicated, the variable number of records to add is being decided by the outcome of a query based on an entry inside tblA (after the insert) and this is then being run on another table (tblC). The SELECT statement from tblC combined with the Select parameter from tblA will then decide how many records I have to insert. Sorry for the (perhaps) confusing way of writing this down, but I’ve been struggling with this for a couple of days now and I really need to get it working. Anybody who can help?Thanks in advance,Sunny Guam

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 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?

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.

Recovering From Transaction Log Deletion In 6.5
I was trying to relocate my transaction log to a bigger drive usingsp_movedevice but I made a mistake in the syntax of the second parameterand put only the path, not the path and the file name.Now my database is marked as "suspect" and I get an error message in my logupon database start up saying that the log file cannot be open.Is there a way to have MS SQL 6.5 "forget" all the logs of this database,create new ones and restart the database? The logs contained nothingimportant, I had truncated them an hour or so before I made my mistake. Ijust want to make sure the data are still usable.When I look at the devices with sp_helpdevice, I can see a log that existand is hopefully in pristine condition and the one that doesn't existanymore.I looked in the archives of various newsgroups but couldn't find somethingthat correspond closely to my situation. I saw something similar but withMS SQL 7.0(http://groups.google.com/groups?hl=...om %26rnum%3D4)using sp_attach_db/sp_detach_db. What would be the equivalent with version6.5?Thanks!Charles--Charles-E. Nadeau Ph.Dhttp://radio.weblogs.com/0111823/

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! Chris P

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. Michael Taylor - 5/31/07 http://p3net.mvps.org
