I wrote a script to archive and delete records rom a table back in 2005 and 2009.
I can't seem to get the syntax right. Any sample script to simply archive and delete records?
This is what I have so far.
DECLARE @ArchiveDate Datetime
SET @ArchiveDate = (SELECT TOP 1 DATEPART(yyyy,Call_Date)
FROM tblCall
ORDER BY Call_Date)
--SELECT @ArchiveDate AS ArchiveDate
DECLARE @Active bit
[Code] ....
I would like to archive /delete data from a 100GB table. I have to delete on the basis of date column. Date column has been added to clustered index But not having an individual non clustered index.
My estimated execution plan shows a index scan.
Should I impose an non-clustered index on the date column then try to archive /delete after confirming the index seek is used in estimated execution plan or, is there any other method to do this?
I've got two tables, one is an archive of the second (tables are identical). I'd like to migrate records from one to the other (as in, move, insert into one while deleting from the other).
I know I can start a transaction, do an INSERT INTO...SELECT, followed by a DELETE, check rows affected, then closing with a commit transaction (or rollback if the counts don't match), but it seems as though I might be over thinking it. Is this considered the optimal approach?
I have two tables called A and B and C. Where A and C has the same schema
A contains the following columns and values
-------------------------------------------
TaskId PoId Podate Approved
1 2 2008-07-07 No
3 4 2007-05-05 No
5 5 2005-08-06 Yes
2 6 2006-07-07 Yes
Table B contains the following columns and values
-------------------------------------------------
TaskId TableName Fromdate Approved_Status
1 A 7/7/2007 No
3 B 2/4/2006 Yes
Now i need to create a stored procedure that should accept the values (Yes/No) from the Approved_Status column in Table B and should look for the same values in the Approved column in Table A. If both values match then the corresponding rows in Table A should be archived in table C which has the same schema as that of Table A. That is the matching columns should get deleted from Table A and shoud be inserted into Table C. In both the tables A and i have the column TaskId as the common column
Pls provide me with full stored procedure code.

The iussue:Sql 2KI have to keep in the database the data from the last 3 months.Every day I have to load 2 millions records in the database.So every day I have to export (in an other database as historical datacontainer) and delete the 2 millions records inserted 3 month + one day ago.The main problem is that delete operation take a while...involvingtransaction log.The question are:1) How can I improve this operation (export/delete)2) If we decide to migrate to SQL 2005, may we use some feature, as"partitioning" to resolve the problems ? In oracle I can use the "truncatepartition" statement, but in sql 2005, I'm reading, it cant be done.This becouse we can think to create a partition on the last three mounts tosplit data. The partitioning function can be dinamic or containing afunction that says "last 3 months ?" I dont think so.May you help usthank youMastino

I have a situation where deleting old records is blocking updating latest records on highly transactional table and getting timeout errors from application.
In details, I have one table called Tran_table1 in OLTP database. This Tran_table1 is highly transactional table, it will receive data for insert/update continuously
While archiving 2 years old records from Tran_table1 into Tran_table1_archive in batches(using DELETE OUTPUT INTO clause), if there is any UPDATEs on Tran_table1,these updates are getting blocked and result is timeout errors in application.
Is there any SQL Server hints to avoid blocking ..
I have a requirement to delete 1 Million records from a table having 10 Million data and it's being queried on 24/7 basis (don't have a downtime). how can I achieve that?
View 13 Replies View RelatedHi everyone!
My problem is, that i don#t know how i can archive the data. That means to documentate when, who, etc. changed the data (in a seperate table).
I tried to solve it with different triggers.
Thanks in advance,

Hi ,
I need to archive my production database to a new Server.....
Is it possible to move data using INSERT INTO ServerName.DBName.dbo.TableName from the current Database Server!!!
Do I need to create a linked server to do this....or shoud I go for DTS..
Thanks

What's the best archiving procedures? :)

I'm working on archiving data from some tables. I've duplicated the data structure, with the exception of not including the IDENTITY specifier on INT columns, so that the archive table will keep the value that was generated in the original table. This is all going well, until I tried to copy the data over where the column is specified as a timestamp data type. I've looked this up and found a couple of things. First, documentation for SQL 2000 says,
Timestamp is a data type that exposes automatically generated binary numbers, which are guaranteed to be unique within a database. Timestamp is used typically as a mechanism for version-stamping table rows. The storage size is 8 bytes.
And then documentation for the soon to be released SQL 2016 on the rowversion data type says,
The timestamp syntax is deprecated. This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.
and
Is a data type that exposes automatically generated, unique binary numbers within a database. rowversion is generally used as a mechanism for version-stamping table rows. The storage size is 8 bytes. The rowversion data type is just an incrementing number and does not preserve a date or a time.
OK, I've read the descriptions, but I don't get it. Why have a timestamp/rowversion data type?
How do I put data into a text or excel file before I attempt a deleteion from a large table. I know how to select the necessary data, but i'm not sure about the t-sql required to put it into a file?
are there any better methods of archiving?
thanks
Regarding SQL Server data, I am looking to implement the beset Data-Archive and Purge policy. Normal, we do SQL Backups and keep the history for some period , for example, 8 weeks, so we can go back and restore any data point in time upto 8 month in past. and we also do Tape backups.
Question is Where can I get nice article or documentation on this to best design such policy where I make sure that I am covered for point in time recovery of database (which is sql backups) and point in time recovery in far past, say, 3 years ago using tape backups, and I need to make sure that I don't repeat the same efforsts.
Any advices or suggestion on this topic.
Thanks,
Is there a way, for example to script a DTS Package, so that it can be deleted and recreated at a later date if necessary? I have quiet alot of these, but few are used regularly. The msdb database is now up to 80 MB. However I don't want to delete them and have no way to recreate them.If I took a backup of msdb and then deleted the packages, would restoring msdb at a later date restore the packages?????
View 1 Replies View RelatedHello,
I have been placed in the position of administering our SQL server 6.5 (Microsoft). Being new to SQL and having some knowledge of databases (used to use Foxpro 2.6 for...DOS!) I am faced with an ever increasing table of incoming call information from our Ascend MAX RAS equipment. This table increases by 900,000 records a month. The previous administrator (no longer available) was using a Visual Foxpro 5 application to archive and remove the data older than 60 days. Unfortunately he left and took with him Visual Fox and all of his project files.
My question is this: Is there an easy way to archive then remove the data older than 60 days from the table? I would like to archive it to a tape drive. We need to maintain this archive for the purposes of searching back through customer calls for IP addresses on certain dates and times. We are an ISP, and occasionally need to give this information to law enforcement agencies. So we cannot just delete it.
Sorry this is so long...
Thanks,

I must admit I dont know all that much about SQL, which is why I hope someone can show me the light. I have a script almost finished, however I have no idea how to have it trim database entries that are older than, say, 90 days. Any ideas?

I need to delete all the records from the table "Floor_Stock" that

How do I delete one record from one table and cascade down all related tables?
Mike B
Hey all,
Here is the scenario. I'm working with two tables:
Contact1
Conthist
Contact1 contains basic contact information and conthist contains history records for those contacts. Conthist can hold many records related to a single contact1 record.
The link between the two tables is a column called accountno.
I'm trying to delete any records in conthist that have an accountno that does not exist in contact1. The queries that I've tried keep returning conthist records that do actually have a matching accountno.
Any help would be appreciated.
Thanks,
Tony
Whenever I try to delete records from a table joined to another table, like so:
DELETE [tblTransaction Detail Local] FROM [tblTransaction Detail Local], [tblTransaction Header] WHERE ([tblTransaction Detail Local].[Transaction ID] = [tblTransaction Header].[Transaction ID]) AND ([tblTransaction Header].[Computer ID] = 3)
I get the error:
Major Error 0x80040E14, Minor Error 25501
> DELETE [tblTransaction Detail Local] FROM [tblTransaction Detail Local], [tblTransaction Header] WHERE ([tblTransaction Detail Local].[Transaction ID] = [tblTransaction Header].[Transaction ID]) AND ([tblTransaction Header].[Computer ID] = 3)
There was an error parsing the query. [ Token line number = 1,Token line offset = 38,Token in error = FROM ]
This is an SQL CE database, and SQL Server Management Studio. Any ideas?
I have a couple SQL tables that have been appended to daily over the last two years. There is now about 50,000,000 records in the table. Does anyone know the fastest way to delete records before a certain date to shorten these tables? Delete queries and everything else I've tried is taking way too long.

View 4 Replies View RelatedApparently, deleting 7,000,000 records from a table of about 20,000,000 is not advisable. We were able to take orders at 8:00AM, but not at 7:59.
So, what's the best way of going about deleting a large number of records? Pretty basic lookup table, no relationships with other tables, 12 or so address-type fields, 4 or 5 simple indexes. I can take it down for a weekend or night, if needed.
DTS the ones to keep to another table, drop the old and rename the new table?
Bulk copy out, truncate and bring back in?
DTS to text, truncate and import back?
Other ways?
Never worked with such a large table and need a little experienced guidance.
Thanks for the help
My Web Host does not provide administrative privilages to the SQL server I have access to. I would like to delete tens of thousands of records from two of my tables without writing to the Transaction Log. Is what I'm trying to do is delete these records quickly without utilizing any of the alotted space my web host has set aside for my transaction log (they give me 50 mb and I go way over that when I run a DELETE statement)
What is the best way to do this?

I have a problem where records in underlying tables of a dataview are being deleted (seemingly at random)
For example.
CREATE TABLE [Employee] (Id int, Name varchar(50))
CREATE TABLE [Company] (Id int, Name varchar(50))
CREATE TABLE [EmployeeCompany] (CompanyId int, EmployeeId int)
CREATE VIEW [dvEmployee]
AS
SELECT *
FROM [Employee] INNER JOIN [EmployeeCompany]
ON [Employee].[Id] = [EmployeeCompany].[EmployeeId]
CREATE TRIGGER [dvEmployeeUpdate]
ON [dbo].[dvEmployee]
INSTEAD OF UPDATE
AS
BEGIN
UPDATE EmployeeCompany
SET Status = INSERTED.Status
FROM EmployeeCompany, INSERTED
WHERE EmployeeCompany.CompanyId = INSERTED.CompanyId
AND EmployeeCompany.EmployeeId = INSERTED.EmployeeId
END
Because the column [Status] is a t-sql keyword, does the fact that the trigger contains the line "SET Status = ..." without saying "SET [Status] = ..." mean that I could lose records in the EmployeeCompany table?
Reason I'm asking is we have an already designed database that is littered with columns named the same as sql keywords (almost every table has a [Status] column, and there are many [Password] columns). When using a dataview on these tables, triggers exist that aren't putting the [] around these column names (the same as my dvEmployeeUpdate trigger above), and somehow we are seemingly randomly losing records. It is very rare, and they are getting completely deleted, and it seems to be the tables that contain the keyword columns and are used in dataviews with instead of triggers that don't put [] around the column names. Nowhere in any trigger or stored procedure is there a DELETE FROM on these tables, and the software running on the database uses only the data views, and doesn't directly access the underlying tables.
I've been going through all of the code adding the [], but my question is simply whether or not anyone has heard of this causing the deletion of any records, or whether there may be something else going on that I should be looking into?
help me out on this one.
i have 2 text boxes in my page.
user enter any number in those two text boxes.
i slect that many record randomly from my main table, and put it into two another tables.
now the problem is coming in how to delete those records which were randomly selected from main table in main table.
for eg
main table contains
srNo. UswerID
1 abcd
2 trtr
3 tret
4 yghg
5 jjhj
user enters in text box1 '2' and in text box2 `1'
so total of 3 random records are selected
and put it into two another table say
table1
sr.no UserID
2 trtr
and table2 contains
sr.no. userid
3 tret
5 jjhj
now i want to delete these records which are sr.no 2,3,5 from the main table.
how do i do it as user can enter any number in the text box.so writing multiple delete statements would not be possible.
how do i write statements or help me with logic.

Hi
I wanted to do a delete rows from a group of table. These tables have a common column UserID. I heard that there is something called ondelete cascade. But I don't know how to set it up and utilise it. Could someone tell me how to do it. Or point me to a tutorial which shows how to do it.
