Hej There.
We have a big problem. We have now for 4th years had a SQL Server
without problems. But sutnely some of the primary keys are deleted.
The subdata to the primary keys are not deleted. This is a big problem
because This is a billing system. Recently there was over 300 primay
keys deleted. Good that we have backup but still... NOOOT good
Can anyone help me to solve this problem!!! PLEASE
Best regards
Danni
Hi Everybody,
Kindly let me know if there is a way of deleting data from primary table without deleting data from its corresponding foreign key table.
Thanks & Regards
hi guys,
just a question regarding database design
i have a table with an auto-generated primary key but the problem is this:
say i have 4 records,so logically they'll be numbered 1 to 4.so the problem is whenever i delete all records and add new ones,the numbering will start from 5 and not 1 again.
how do i remedy this?
thanx

Hi all,
Can anyone suggest me on Adding primary key to a table which has already a primary key.
Thanks,

Hi,
I have recently been looking at a database and wondered if anyone can tell me what the advantages are supporting a unique collumn, which can essentially be seen as the primary key, with an identity seed integer primary key.
For example:
id [unique integer auto incremented primary key - not null],
ClientCode [unique index varchar - not null],
name [varchar null],
surname [varchar null]
isn't it just better to use ClientCode as the primary key straight of because when one references the above table, it can be done easier with the ClientCode since you dont have to do a lookup on the ClientCode everytime.
Regards
Mike
We have a table, which has one clustered index and one non clustered index(primary key). I want to drop the existing clustered index and make the primary key as clustered. Is there any easy way to do that. Will Drop_Existing support on this matter?

I have the following table
CREATE TABLE [dbo].[property_instance] (
[property_instance_id] [int] IDENTITY (1, 1) NOT NULL ,
[application_id] [int] NOT NULL ,
[owner_id] [nvarchar] (100) NOT NULL ,
[property_id] [int] NOT NULL ,
[owner_type_id] [int] NOT NULL ,
[property_value] [ntext] NOT NULL ,
[date_created] [datetime] NOT NULL ,
[date_modified] [datetime] NULL
)
I have created an 'artificial' primary key, property_instance_id. The 'true' primary key is application_id, owner_id, property_id and owner_type_id
In this specific instance
- property_instance_id will never be a foreign key into another table
- queries will generally use application_id, owner_id, property_id and owner_type_id in the WHERE clause when searching for a particular row
- Once inserted, none of the application_id, owner_id, property_id or owner_type_id columns will ever be modified
I generally like to create artificial primary keys whenever the primary key would otherwise consist of more than 2 columns.
What do people think the advantages and disadvantages of each technique are? Do you recommend I go with the existing model, or should I remove the artificial primary key column and just go with a 4 column primary key for this table?
Thanks Matt
Please HELP!!
I need a query to DELETE the first few records in a table. For example: something like .....delete top 1000 from tablename. I figured that TOP dosent work with the DELETE. It only works with SELECT and UPDATE statments.
I cannot hardcode any values in the WHERE clause due to certain constraints in my application.
KINDLY HELP, THIS IS URGENT.
I have edited the aspnet_Users_CreateUser stored procedure so that the UserId that is created when a new user is created is copied to a UserId field in another table. However, when I use the website administration tool to delete users that have been created, it gives me an error saying the delete statement conflicted with the reference constraint. I then added the following code in the aspnet_Users_DeleteUser procedure....
IF ((@TablesToDeleteFrom & 16) <> 0 AND
(EXISTS (SELECT name FROM sysobjects WHERE (name = N'vw_tt') AND (type = 'V'))))
BEGIN
DELETE FROM dbo.userclassset WHERE @UserId = UserId
SELECT @ErrorCode = @@ERROR,
@RowCount = @@ROWCOUNT
IF( @ErrorCode <> 0 )
GOTO Cleanup
IF (@RowCount <> 0)
SELECT @NumTablesDeletedFrom = @NumTablesDeletedFrom + 1 hdhd
END
This code was then added to the function at the end which deletes the data from the aspnet_Users table when everything else has been removed
(@TablesToDeleteFrom & 16) <> 0 AND
Now when I delete a user in the website admin tool, it "deletes" (with no error) the user from the list but doesnt actually physically delete it from the database.
Any ideas?
I have a data source which I created a custom statement for which I need to delete from. I created the folowing selecct statement
SELECT [CompId], [Description], [CompName], [OS], [UserName], [DriverEntryId] FROM [SrcComputer] WHERE ([UserName] = @UserName)
I wrote the following DELETE statement
DELETE FROM SrcComputer WHERE (CompId = @CompId)
I have tested it in SQL server management and it does what I want it to do, but I don't know how to use it in my code. I put it inside of the DELETE tab inside of my custome statement and added a delete button inside of the gridview which utializes my data source, but it's not working. I don't know how to set the CompId variable? I want the statement to delete the row that the user clicks on. Can anyone give me some advice?
I have three tables
1. membership table(aspnet_membership table)
2. User Contacts table
3. Address table
These three table have relation ship with one another through a UserId field.
How will you set up cascaded delete on these tables, Like if I delete a user in the membership table I want the related records in the other tables to be deleted as well. Cascaded delete is it something done through code, or is it definde when the tables are created.
Please advice.
here i a again.. because im really having problems in deleting rows from a gridview... here is my code
SelectCommand="SELECT UserId, First, Last, Email, CreateDate, LastLoginDate, IsApproved, IsLockedOut FROM aspnet_Membership"
DeleteCommand="DELETE FROM aspnet_Membership WHERE [UserId] = @UserId"
ConnectionString="<%$ ConnectionStrings:ConnectionString2 %>" >
<DeleteParameters>
<asp:Parameter Name="UserId" Type="Int32"/>
</DeleteParameters>
It is working but when i click the delete button.. this appears

Hey Guys,I have Performance Monitor running and storing the network usage to my MsSQL database, and this is done a few times a minute. I have a page that then shows show much of my bandwidth is being used. As you can gather, the database quickly starts filling up with hundrreds of records so I could do with a script that delete these records. I cant simply delete all records because that would cause my webpage to fail so I need a way to delete all records apart from the latest one. Wondering if anyone would know how I could do this?

I am new to SQL backups but what I have done is created a script sp_BackupProcessor that is used to determine which backup type is run (Full,Differential,Transaction). I am backing up to the local drive and then our tape backup system backs up the files on our local system to tape. I only want to keep 3 days worth of backups on our local machine since the same information is stored on tape. What is the best way to handle this? Any help or ideas would be appreciated. I have included my script for reference.

Does anyone know why it takes a long time (Approx 10 minutes) to delete a DB. I have 2 identical environments for test and prod. I can delete DBs from my test environment quickly but it takes forever to delete a DB from the production environment. I am running SQL2000 SP3a. There are about 25 DBs in the environment with their sized ranging from 100meg to 2 gig. The only differnece in the environments is all test DBs are simple recovery mode and modt prod DBs are full.
Thanks,

I have two identical databases. I need to delete the even customer numbers from the first database and the odd numbers from the other database. I know I can do this writing a delete statement for each table. However there are a total of 54 tables.
Does anyone know a faster way to write the script without writing 54 scripts?
I would appreciate your help.
As always you guys are the greatest.

i have a table that i think is bad -
how do i delete the table?
also i want to copy this same table from another database -
can i use enterprise manager to copy the same table in place of the deleted table?
Hey all.
I have a table with 100,000 plus records in it, and some are duplicates. Is there any way to delete one of them and not the other. For instance, if I duplicate the table I could run this query.
<cfquery name="query1" datasource="datasource">
DELETE DISTINCT
FROM tablename
WHERE FirstName in ( SELECT FirstName from tablename1 where tablename1.FirstName = tablename.FIRST_NAME AND tablename1.LastName = tablename.LAST_NAME AND tablename1.State = tablename.STATE)
</cfquery>
However, it doesn't work. I know the distinct is not correct. But does anyone know how to achieve this, I have looked all over, and everything I try deletes both records. I was thinking of using some kindof count statement, but it still deletes both of them. Please help. Thanks

I have a table with a load of orphaned records (I know... poor design)
I'm trying to get rid of them, but I'm having a brain cramp.
I need to delete all the records from the table "Floor_Stock" that
would be returned by this select statement:
SELECT FLOOR_STOCK.PRODUCT, FLOOR_STOCK.SITE
FROM PRODUCT_MASTER INNER JOIN
FLOOR_STOCK ON PRODUCT_MASTER.PRODUCT =
FLOOR_STOCK.PRODUCT LEFT OUTER JOIN
BOD_HEADER ON FLOOR_STOCK.PRODUCT =
BOD_HEADER.PRODUCT AND FLOOR_STOCK.SITE =
BOD_HEADER.SITE
WHERE (BOD_HEADER.BOD_INDEX IS NULL) AND
(PRODUCT_MASTER.PROD_TYPE IN ('f', 'n', 'k', 'b', 'l', 's'))
I was thinking along the lines of:
DELETE FROM FLOOR_STOCK INNER JOIN
(SELECT FLOOR_STOCK. PRODUCT, FLOOR_STOCK.SITE
FROM PRODUCT_MASTER INNER JOIN
FLOOR_STOCK ON PRODUCT_MASTER. PRODUCT =
FLOOR_STOCK.PRODUCT
LEFT OUTER JOIN BOD_HEADER ON FLOOR_STOCK. PRODUCT =
BOD_HEADER. PRODUCT AND FLOOR_STOCK.SITE = BOD_HEADER.SITE
WHERE (BOD_HEADER.BOD_INDEX IS NULL) AND
(PRODUCT_MASTER.PROD_TYPE IN ('f', 'n', 'k', 'b', 'l', 's'))) F ON
FLOOR_STOCK. PRODUCT = F. PRODUCT
AND FLOOR_STOCK.SITE = F.SITE
... but Sql Server just laughs at me: "Incorrect Syntax near the keyword INNER"
I have a database and I see that I have a lot of TRN files behind it taking up more than 82GB disk space.I have a TRN file from Jan until today. I plan to delete every one of them until April to recover 59 GB of disk space. Would that be OK?
