You might have a record that has a foreign key value related to it, or you might have violated a check constraint.

Deleting Massive Data From A Table
Jan 20, 2014I have to delete a ton of data from a SQL table. I have a unique identifier called the version. I would like to use if not in these versions then delete. I tried to using the statement below, but learned the hard way that it created an error this is the message I got....
Msg 9002, Level 17, State 4, Line 3...
The transaction log for database 'MonthEnds' is full due to 'ACTIVE_TRANSACTION'.
I was reading about truncate, I am not sure how I would do this or how I would setup the statement.

Deleting Data By Comparing To Another Table
Jul 20, 2005I have an entry form allowing customers to enter up to 15 skus (productid) at a time, so they can make a multiple order, instead of enteringone sku, then submitting it, then returing to the form to submit thesecond one, and so forth.From time to time, the sku they enter will be wrong, or discontiued, soit will not submit an order.Therefore, when they are done submitting their 15 skus through the orderform, I want a list showing them all of those skus that came back blank,or were not found in the database.I'm doing this by creating two tables. A shopping cart, which holds allthe skus that were returned, and a holding table, that holds all theskus that were submitted. I want to then delete all the skus in theholding page that match the skus in teh cart (because they are goodskus) which will then leave the unmatched skus in the holding table.I'll then scroll out the contents of the holding table, to show them theskus that were not found in the database.(confused yet?)So what I want to do is have some sql that will delete from the holdingtable where the sku = the sku in the cart. I've tried writing this, butit dosn't work.I tiried this delete from holding_table where sku = cart.skuI was hoping this would work, but it dosn't. Is there a way for me to dothis?Thanks!Bill*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!
View 2 Replies View RelatedDeleting Data Using Table Prefix
May 30, 2006
I can run a select to retrieve data using a prefix 'a' for the specific table involved. However when I try to run a delete using the same criteria it fails telling me
Msg 102, Level 15, State 1,.......Line 1
Incorrect syntax near 'a'
The Select statement looks like:
select count(*) from schema.table a where a.customer_id=1234
The Delete looks like:
delete from schema.table a where a.customer_id=1234
What am I doing wrong here? and how can I prefix the table, because the command I want to run is much more complicated than the example above and it needs the prefix

Deleting Large Amount Of Data From The Table......
May 18, 2001I need to delete data from a particular table which has more than half a million records. The data needs to be deleted is more than 200,000 records from the table. What is the best way to delete the data from the table other than importing into a temporary table and performing the same operation?
Let me know if the strategy to be followed is okay.
1. Drop all the triggers
2. Drop all the indexes
3. Write a procedure with a loop setting ROWCOUNT to 1000 and delete the records. ( since if I try to delete all the rows it will give timeout error )
The above procedure will delete 1000 records for each batch inside the loop till it wipes out all the data for the specified condition.
4. Recreate Indexes and Triggers.
Please let me know if there are any other optimal solution.
Thanx,
Zombie

Reduce Table Size Without Deleting Data
Jul 20, 2006We are using SQL Server 2000 Standard ed, sp4 on Server 2000 Advanced.We have one table that is three times as large as the rest of the database.Most of the data is static after approximately 3-6 months, but we arerequired to keep it for 8 years. I would like to archive this table (A), butthere are complications.1. the only way to access the data is through the application (they areimages produced by the application-built on Power-Builder)2. there are multiple tables refrencing this table and vise-versa3. we restore the entire db to two other servers for testing and trainingregularly4. there might be more complications that have not been thought ofCurrently, our only plan is to setup a seperate server with a copy of this dbon it and the application. Leave only the tables necessary to access the data,and if this 'archive' works, remove from production the data from the table Aand all references to the table A from rows on the other tables.I mentioned #3 because someone mentioned a third party tool that may be ableto pull the data from the table, archive it elsewhere, and at the same time,place a 'pointer' in the table to the new storage location. The tool theymentioned only works on Oracle and we have not explored beyond that yet.I am ready to explore ideas and suggestions; I am still new to the DBA world,I am out of ideas.Thank you!--Message posted via SQLMonster.comhttp://www.sqlmonster.com/Uwe/Forum...eneral/200607/1

SQL Server 2008 :: Deleting Data (rows) From Table To Reclaim Space?
Feb 11, 2015I have a table 300+GB. it holds 10 years of Data. I need to delete 5 years of data and put it to another server so I can have more space.
If I delete 5 years of data, Transaction log gets so huge and size of the database even gets bigger because of the .ldf file which even gets bigger! I think I can shrink the log file and the data file. Is this the best way to do it?

View 8 Replies View RelatedINSERT Data Into Table That Maybe Have That Primary Key Already
May 12, 2007Hi, I'm not user to inserting data into databases, usually I just read the data. So I think my problem might be pretty common.I have a table of longitudes, latitudes, city names, and country names. I set the primary key to be the columns longitude and latitude. I have a method that generates the user's location and the mentioned data. So I want to only insert the new data into the database if it is new and unique. currently if the same user goes to my site, it inserts the data fine the first time and then throws and error the second time because it is inserting duplicate primary key information. Do I need to query the database to see if the data record already exists? or is there a way to insert the record only if it is "new"?? Thanks for the help!!
View 2 Replies View RelatedSql Table Data Stroring Based On Varchar Primary Key
Jan 17, 2008Hi,
I have a Users table that I use for membership. I am using username varchar(30) as the primary key for this table since username will always be unique.
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 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 99,999 rows will have to move.
Bottom line, insert, delete will be very 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
SQL 2012 :: Auto ID Primary Key Specified As Int And Table Data Is Deleted Periodically?
Jun 25, 2015I have a table that has a primary key that is auto incremented by 1. This table's data is cleared out periodically and as data gets added the auto id primary key continues to increase in numeric value. Once the data is cleared from the table the auto id names could be used again(the eventId is not stored) Currently the eventID is at 26,581,399. I know the maximum int value is 2,147,483,647.
How should I handle this? or rebuild the table every time the data is cleared(problematically)?
Fix Legacy Data - Missing Primary Key + Duplication Record + Large Table
Nov 17, 2005We have a large table which is very old and not much ppl take care about, recently there is a performance problem from the report need to query to this table. Eventally we find that this table have primary key missing and there is duplicate data which make "alter table add primary key" don't work
Besides the data size of this table require unacceptable time to execute something like "insert into new_table_with_pk from select distinct * from old table"
Do you have any recommendation of fixing this? As the application run on oracle , sybase and sql server, is that cross database approace will work?
SQL Server 2008 :: Does Change Data Capture Require A Table Have Primary Key
Jan 13, 2013Or can it record before and after column changes based on the LSN only?
An extract from a file based legacy accounting system is performed every night. The system does not have a primary key because transactions are managed through program code. (the more things change...). The extract is copied to text in Unix and FTP'd to Windows, where the file is loaded into SQL Server by kill & fill. Because of the expense of modifying the source system, there is enormous inertia/resistance to injecting a primary key at the source, so kill & fill it stays.
In reading about Change Data Capture, it seemed to me that column level insert update and delete are stored in tables that remember the before and after content of each column tracked. In my reading I have seen many references to the LSN to decide when and what to record as changed, but I have not seen any refereference to the necessity of a primary key for Change Data Capture to work. This is in contrast to replication, where the requirement for the existence of a primary key is made plain.
Is it possible to use Change Data Capture against a table without a primary key? How to use it to change the extract from kill and fill to incremental.

Power Pivot :: Deleting Data Content From Data Model
Sep 10, 2013I don't know if the question has been nailed down. Aside from deleting tables, can we delete the *content* of data within the tables. It doesn't seem crazy that, if you can pull in data from a feed then you should be able to remove the content out again (without also destroying the user's meta-data work ). Reasons for this include:
- Security (a user may not have rights to see *my* data and should go refresh their own)
- Size (workbook doesn't need to have GB's of irrelevant data saved to disk in a workbook if it was just useful during development phase to a pre-production data feed)
- Bad data (pre-production data feed is not good data)
- User-friendliness (data feed was refreshed 2 years ago and workbook was saved to file server. Users shouldn't be presented with irrelevant data, but should get empty pivot tables until they go do their refresh)
Obviously Excel internally knows how to clear out PowerPivot data, given the prompt shown here: [URL] ....
But how does a user initiate this on their own (corruption aside)?
Previous time this question was asked, without a real resolution: [URL] ....
Archive Data Instead Of Deleting It To Prevent 4GB Data Limit
Mar 14, 2008We are running SQL Server 2005 express on Windows 2003. The database server gets significant amounts of data.
Because of the 4GB data limit we have a daily cron task which goes through and deletes data older then 90 days.
We would like a way to archive this data instead of deleting it. Is there any way to take data and compress it and store it in a different way, so that if needed, customers can query directly out from the compressed data? Cleary querying from compressed would be slower but that is ok.
Any other solutions that would allow us to archive data instead of deleting it? Thanks.

Deleting Row From Table
Jun 17, 2008Hi guys,
I have a table which consist of 6,185 rows and from this table I want to delete 427 rows. I have placed the 427 rows in a separate table. So how do I delete these 427 from the original table(6185 rows).
I should also mention that the table does not have a primary key so I was thinking about something like this but it didn't work
delete o.CardNumber
,o.ref_no
,o.tran_date
,o.tran_val
from test6185 o
where exists (select h.CardNumber
,h.ref_no
,h.tran_date
,h.tran_val
from test427 h
where( h.ref_no=o.ref_no and
h.CardNumber = o.CardNumber and
h.tran_date =o.tran_date and
h.tran_val =o.tran_val
))
order by cardnumber
