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

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

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

Insert Parent Child Records...
Hello, We have a complex functionality of migrating data from a single record into multiple parent child tables. To give you an example, lets us assume that we have a single table src_orders in the source database. We have a parent Order table and a child OrderDetails table in the target database. We need to pick one row from src_orders and insert this row in the Order table, pick up its PK (which is an identity column) and then use this to insert rows (say 5) in the OrderDetails table. Again, we go back to the source, take a row, insert it into Orders, pick up the Orders PK and insert n rows in OrderDetails. As of now, we are using the following approach for achieving this functionality. 1. Get the identity generated from the target table and store both the source table id and the target table id in a recordset. 2. Use the recordset as the source to a foreachloop , using foreachADO enumerator 3. Use data flow tasks to get the fields from the parent table for the source id, that needs to be inserted into the target child table In case I have not ended up confusing everyone, can anyone validate this or suggest a better approach? :) Thanks, Satya

Selecting TOP X Child Records For A Parent Record
Hi,I have a stored procedure that has to extract the child records forparticular parent records.The issue is that in some cases I do not want to extract all the childrecords only a certain number of them.Firstly I identify all the parent records that have the requird numberof child records and insert them into the result table.insert into t_AuditQualifiedNumberExtractDetails(BatchNumber,EntryRecordID,LN,AdditionalQualCritPassed)(select t1.BatchNumber,t1.EntryRecordID,t1.LN,t1.AdditionalQualCritPassedfrom(select BatchNumber,RecordType,EntryRecordID,LN,AdditionalQualCritPassedfrom t_AuditQualifiedNumberExtractDetails_Temp) as t1inner join(select BatchNumber,RecordType,EntryRecordID,Count(*) as AssignedNumbers,max(TotalNumbers) as TotalNumbersfrom t_AuditQualifiedNumberExtractDetails_Tempgroup by BatchNumber, RecordType, EntryRecordIDhaving count(*) = max(TotalNumbers)) as t2on t1.BatchNumber = t2.BatchNumberand t1.RecordType = t2.RecordTypeand t1.EntryRecordID = t2.EntryRecordID)then insert the remaining records into a temp table where the number ofrecords required does not equal the total number of child records, andthenloop through each record manipulating the ROWNUMBER to only selectthe number of child records needed.insert into @t_QualificationMismatchedAllocs([BatchNumber],[RecordType],[EntryRecordID],[AssignedNumbers],[TotalNumbers])(select BatchNumber,RecordType,EntryRecordID,Count(*) as AssignedNumbers,max(TotalNumbers) as TotalNumbersfrom t_AuditQualifiedNumberExtractDetails_Tempgroup by BatchNumber, RecordType, EntryRecordIDhaving count(*) <max(TotalNumbers))SELECT @QualificationMismatched_RowCnt = 1SELECT @MaxQualificationMismatched = (select count(*) from@t_QualificationMismatchedAllocs)while @QualificationMismatched_RowCnt <= @MaxQualificationMismatchedbegin--## Get Prize Draw to extract numbers forselect @RecordType = RecordType,@EntryRecordID = EntryRecordID,@AssignedNumbers = AssignedNumbers,@TotalNumbers = TotalNumbersfrom @t_QualificationMismatchedAllocswhere QualMismatchedAllocsRowNum = @QualificationMismatched_RowCntSET ROWCOUNT @TotalNumbersinsert into t_AuditQualifiedNumberExtractDetails(BatchNumber,EntryRecordID,LN,AdditionalQualCritPassed)(select BatchNumber,EntryRecordID,LN,AdditionalQualCritPassedfrom t_AuditQualifiedNumberExtractDetails_Tempwhere RecordType = @RecordTypeand EntryRecordID = @EntryRecordID)SET @QualificationMismatched_RowCnt =QualificationMismatched_RowCnt + 1SET ROWCOUNT 0endIs there a better methodology for doing this .....Is the use of a table variable here incorrect ?Should I be using a temporary table or indexed table if there are alarge number of parent records where the child records required doesnot match the total number of child records ?

Writing Parent/Child Records To Flat File
I have a set of parent/child records that need to be exported to a space delimited Flat File. Each parent record must be followed by 3 child records, each on their own line with different format. I have a prototype using the Derived Column component that concatinates the various fields of each record into one "wide" text column. This fools SSIS to think that each row has the same format. Then I merge them together using an artificial sort id. But this seems overly tedious and very brittle. What would be the best approach to writing these records out? I'm hoping there is a better more maintainable method. Thanks, Jon

Help With How To Send E-Mail (Parent - Child Matching Records) From SQL 2005 Stored Procedure.
Folks,Using NorthWind as Example: Parent Table derived from: Categories. I added a new Column E-Mail and Selecting rows where Category Id <=3. Here is my Data. Category ID Category Name Category E-mail 1 Beverages Beverages.com 2 Condiments Condiments.com 3 Confections Child Table derived from: Products. I am Selecting rows where Category Id <=3. Here is my Sample Data. Category ID Product Name Quantity Per Unit 1 Chang 24 - 12 oz bottles 1 Côte de Blaye 12 - 75 cl bottles 1 Ipoh Coffee 16 - 500 g tins 1 Outback Lager 24 - 355 ml bottles 2 Aniseed Syrup 12 - 550 ml bottles 2 Chef Anton's Gumbo Mix 36 boxes 2 Louisiana Hot Spiced Okra 24 - 8 oz jars 2 Northwoods Cranberry Sauce 12 - 12 oz jars 3 Chocolade 10 pkgs. 3 Gumbär Gummibärchen 100 - 250 g bags 3 Maxilaku 24 - 50 g pkgs. 3 Scottish Longbreads 10 boxes x 8 pieces 3 Sir Rodney's Scones 24 pkgs. x 4 pieces 3 Tarte au sucre 48 piesI would like to read 1st Category Id, Category E-Mail from Categories Table (ie. Category Id = 1), find that in Products Table. If match, extract matching records for that Category from Both Tables (Categories.CategoryID, Products.ProductName, Products.QuantityPerUnit) and e-mail them based on E-Mail Address from Parent (Categories ) Table. If no E-Mail Address is listed, do not create output file. In this instance Category Id = 3.Basically I want to select 1st record from Parent Table (Here is Category) and search for all matching Products in Products Table. And Create an E-mail and sending just those matching records. Repeat the same process for remaining rows from Categories Table. I am expecting my E-Mail Output like this: For Category Id: 1 Category ID Product Name Quantity Per Unit 1 Chang 24 - 12 oz bottles 1 Côte de Blaye 12 - 75 cl bottles 1 Ipoh Coffee 16 - 500 g tins 1 Outback Lager 24 - 355 ml bottlesFor Category Id: 2 Category ID Product Name Quantity Per Unit 2 Aniseed Syrup 12 - 550 ml bottles 2 Chef Anton's Gumbo Mix 36 boxes 2 Louisiana Hot Spiced Okra 24 - 8 oz jars 2 Northwoods Cranberry Sauce 12 - 12 oz jarsI am not extracting the Data for any user Interface (ie. Grid View/Form View Etc). I will just create a Command Button in an ASP.NET 2.0 form to extract Data. My Tables are in SQL 2005. I was thinking to read the Category records in a Data Reader and within the While Loop, call a SP to retrieve the matching records from Products Table. If matching records found, call System SP_Mail to send the E-mail. The drawback with that for every category records (Within While Loop) I need to call my SP to get Products Data. Will be OVERKILL? Ideally I would like extract my records with one call to a SP. Is there any way I can run a while loop inside the SP and extract Child Data based on Parent Record? Any Help or sample URL, Tutorial Page will be appreciated. Thanks

Trying To Return A Single Record For Each Client From Child Table Based Upon A Field Of Date Type In Child Table
I have table "Clients" who have associated records in table "Mailings" I want to populate a gridview using a single query that grabs all the info I need so that I may utilize the gridview's built in sorting. I'm trying to return records containing the next upcoming mailing for each client. The closest I can get is below: I'm using GROUP BY because it allows me to return a single record for each client and the MIN part allows me to return the associated record in the mailings table for each client that contains the next upcoming 'send_date' SELECT MIN(dbo.tbl_clients.client_last_name) AS exp_last_name, MIN(dbo.tbl_mailings.send_date) AS exp_send_date, MIN(dbo.tbl_mailings.user_id) AS exp_user_id, dbo.tbl_clients.client_id, MIN(dbo.tbl_mailings.mailing_id) AS exp_mailing_idFROM dbo.tbl_clients INNER JOIN dbo.tbl_mailings ON dbo.tbl_clients.client_id = dbo.tbl_mailings.client_idWHERE (dbo.tbl_mailings.user_id = 1000)GROUP BY dbo.tbl_clients.client_id The user_id set at 1000 part is what makes it rightly pull in all clients for a particular user. Problem is, by using the GROUP BY statement I'm just getting the lowest 'mailing_id' number and NOT the actual entry associated with mailing item I want to return. Same goes for the last_name field. Perhaps I need to have a subquery within my WHERE clause?Or am I barking up the wrong tree entirely..

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.

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.

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

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.

SQL Server Query, Are You Able To Bunch Together Child Table Fields.
Hi all, I'm using SQL Server 2005 along side Visual Studio 2005, using VB to create a web application at work. Now I'd like to bunch together some child fields in a gridview when displayed. Have a look at the attached pic to show what I would like. Is this possible via a query or would I need to set something up on the gridview to do this? Cheers, Paul.

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
