Deleting From 3 Tables

Apr 22, 2008

Hello everyone,

I have to delete some rows from three different tables. My tables are:

- VERSION_1
- ID


- VERSION_2
- ID_VERSION FOREIGN KEY


- VERSION_3
- ID_VERSION FOREIGN KEY

The 3 tables are related to each other by the VERSION_1 ID.

what i have to do is deleting first from VERSION_3, then from Version_2 and finally from VERSION_1. This is what i got so far:

DELETE FROM VERSION_3, VERSION_2, VERSION_1 WHERE VERSION_3.ID_VERSION = ? AND VERSION_2.ID_VERSION = ? AND VERSION_1.ID = ?

I cannot make it work, could someone please help me? i am stuck at this.

Thanks in advance

Deleting Tables

Aug 24, 2005

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,

Issue table contais all the magazine issues. Outlook table contains all the pages of the Issue table. And the Links table contains the links or connection between parent page and child page. So here's what I wanted to do. When I click the delete issue button, I want to delete any pages, links, and issue from three tables that matches the issue ID that I wanted to delete. So for example, if I wanted to delete issueID 2, all the pages in the Outlook table and any links of those pages(lnkFromID) that are in the Links table should be deleted too. The lnkFromID and lnkToID are foriegn key of Outlook.ID table. The lnkFromID is the parent and lnkToID is the child.

I was wondering that maybe I can three delete statements for three tables. Is this a possibility? So any help is much appreciated.

Deleting Rows From Many Tables

May 19, 2006

What I'm trying to do is delete a user and all their related information within the other tables. I'm not wanting to delete the table, just one column with that user and their related information. So my Primary_Key is UserID within the table [alumni] and my three Foreign_Keys are CommentID, PhotoID, and AlbumID within the tables [comments], [photos], and [albums]. Here is some of the code that I have:
<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:SoderquistString %>"
DeleteCommand="DELETE FROM [alumni] WHERE [UserID] = @UserID"
SelectCommand="SELECT [UserID], [UserName], [FirstName], [LastName], [State] FROM [alumni] WHERE ([State] = @State)">
<DeleteParameters>
<asp:Parameter Name="UserID" Type="Int32" />
</DeleteParameters>
<SelectParameters>
<asp:ControlParameter ControlID="DropDownList1" Name="state" PropertyName="SelectedValue"
Type="String" />
</SelectParameters>
</asp:SqlDataSource>
The users are set up in GridView form. Is there some type of DELETE command that I need to be writing that is different than the one above? I have tried adding onto the following DELETE statment:
DeleteCommand="DELETE FROM [alumni] WHERE [UserID] = @UserID
DELETE FROM [photo] WHERE [UserID] = @UserID;
DELETE FROM [album] WHERE [UserID] = @UserID;
DELETE FROM [comment] WHERE [UserID] = @UserID;
...but that doesn't work...and doesn't look right. I would really appreciate anyones suggestions or help that you may be able to provide. Thank you!

Deleting Duplicates From Around 25 Tables

Jan 6, 2014

I need to remove duplicate data from around 25 tables. I want to use a while loop to go through all tables. If I list out all of the column names the query runs fine, but since there are 25 tables some with 50 plus columns I was hoping to use something like the following, which errors out because my sub queries return more than one result.

SELECT q.* from
(Select ROW_NUMBER() OVER ( Partition BY (SELECT [name] AS [Name] FROM syscolumns
WHERE id = (SELECT id FROM sysobjects
WHERE type = 'U'
AND [Name] = 'Orders')
)
Order by (select top 1 [name] AS [Name] FROM syscolumns

Updating/Deleting Multiple Tables Simultaneously

Mar 1, 2005

Hi,

I'm using ASP with a JScript variant and MSSQL Server 2000. I would like to write a script that basically erases all data except for a few things.

Is there a way to update multiple tables at once without having to write lines and lines of code? I tried UPDATE tbl1,tbl2 SET uid='asc', but to no avail. It gave me a syntax error. My thinking behind it is something like... UPDATE dbo.* SET uid='mferguson' and after that I can delete stuff like DELETE dbo.*... Any ideas?

I know the above is ASP, I've tried this thread in the ASP forum with no avail... they referred me to this forum.

Deleting Duplicate Records From Lots Of Tables

Aug 29, 2006

Hi All,

So.. I'm a complete newb to SQL stuff.

I managed to find the 'Deleting Duplicate Records' from SQLTeam.com (thanks, by the way!!).. I managed to modify it for one of my tables (one of 14).


-- Add a new column

Alter table dbo.tblMyDocsSize add NewPK int NULL
go

-- populate the new Primary Key
declare @intCounter int
set @intCounter = 0
update dbo.tblMyDocsSize
SET @intCounter = NewPK = @intCounter + 1

-- ID the records to delete and get one primary key value also
-- We'll delete all but this primary key
select strComputer, strATUUser, RecCount=count(*), PktoKeep = max(NewPK)
into #dupes
from dbo.tblMyDocsSize
group by strComputer, strATUUser
having count(*) > 1
order by count(*) desc, strComputer, strATUUser

-- delete dupes except one Primary key for each dup record
deletedbo.tblMyDocsSize
fromdbo.tblMyDocsSize a join #dupes d
ond.strComputer = a.strComputer
andd.strATUUser = a.strATUUser
wherea.NewPK not in (select PKtoKeep from #dupes)

-- remove the NewPK column
ALTER TABLE dbo.tblMyDocsSize DROP COLUMN NewPK
go

drop table #dupes


Now that I've got that figured out, I need to write the same thing to fix the other 13 tables (with different column info)- and I'll need to run this daily.

Basically I've put together some vbscript that gathers inventory data and drops it into an MSDE db (sorry - goin for 'free' stuff right now). Problem is it has to run daily so that I'm sure to capture computers that turned on at different times etc which ever-increases my database 'till I bounce off the 2GB limit of MSDE.

So the question is, what would be the best way to do this? Can I put the code into a stored procedure that I can execute each day?


Thanks for your help....

Deleting Records From Multiple Tables In SQL Server

Jul 13, 2007

I'm new to relational database concepts and designs, but what i've learned so far has been helpful. I now know how to select certain records from multiple tables using joins, etc. Now I need info on how to do complete deletes. I've tried reading articles on cascading deletes, but the people writing them are so verbose that they are confusing to understand for a beginner. I hope someone could help me with this problem.



I have sql server 2005. I use visual studio 2005. In the database I've created the following tables(with their column names):



Table 1: Classes --Columns: ClassID, ClassName

Table 2: Roster--Columns: ClassID, StudentID, Student Name

Table 3: Assignments--Columns: ClassID, AssignmentID, AssignmentName

Table 4: Scores--StudentID, AssignmentID, Score



What I can't seem to figure out is how can I delete a class (ClassID) from Classes and as a result of this one deletion, delete all students in the Roster table associated with that class, delete all assignments associated with that class, delete all scores associated with all assignments associated with that class in one DELETE sql statement.



What I tried to do in sql server management studio is set the ClassID in Classes as a primary key, then set foreign keys to the other three tables. However, also set AssignmentID in Table 4 as a foreign key to Table 3.



The stored procedure I created was



DELETE FROM Classes WHERE ClassID=@classid



I thought, since I established ClassID as a primary key in Classes, that by deleting it, it would also delete all other rows in the foreign tables that have the same value in their ClassID columns. But I get errors when I run the query. The error said:



The DELETE statement conflicted with the REFERENCE constraint "FK_Roster_Classes1". The conflict occurred in database "database", table "dbo.Roster", column 'ClassID'.
The statement has been terminated.



What are reference constraints? What are they talking about? Plus is the query correct? If not, how would I go about solving my problem. Would I have to do joins while deleting?

I thought I was doing a cascade delete. The articles I read kept insisting that cascade deletes are deletes where if you delete a record from a parent table, then the rows in the child table will also be deleted, but I get the error.



Did I approach this right? If not, please show me how, and please, please explain it like I'm a four year old.



Further, is there something else I need to do besides assigning primary keys and foreign keys?

Stored Procedure For Deleting Multiple Tables/rows

Jul 24, 2007

Hi,
I have a relational database with the primary table, table01. And 2 child/foreign tables, table02 and table03. All 3 tables shared the same key - [ID].
I am not sure if this is the correct approach but I am trying to create a stored procedure where if I were to delete a the row in table01 (primary), the procedure will automatically delete the common row in both table02 and table03.
I have come up with something like that but it does not seems to be correct.
CREATE PROCEDURE [sp_delete_test01_1] (@id [int])
AS
DELETE [test01] DELETE [test02] DELETE [test03]
WHERE  ( [id] = @id)GO
Your advise please. Many Thanks.

SQL Server 2012 :: Removing / Deleting Data From 2 Tables

Mar 11, 2015

I have found a bunch of duplicate records in our housing database that ideally I need to delete.There are two tables that I need to remove data from ih_cml_log_entry and ih_cml_log_notes. There is no unique identifier between the tables for a log entry. So I have had to join on the person_ref, log_seq and the date/time of entry.How do I go about deleting the data - I've used the script below to identify what I need to delete -

SELECT *
FROM
(
select cml.person_ref, cml.open_date + open_time as 'datetime',cml.open_user,cml.log_type
,ROW_NUMBER() OVER (PARTITION BY cml.person_ref, cml.open_date + cml.open_time,cml.open_user,cml.log_type ORDER BY (SELECT 0)) AS RowNo
,n.note

Why Would Tables Pulled In From ODBC In Access Be Different Than Tables In SQL 2005 Tables?

Jan 24, 2008

I'm new to my company, although not new to SQL 2005 and I found something interesting. I don't have an ERD yet, and so I was asking a co-worker what table some data was in, they told me a table that is NOT in SQL Server 2005's list of tables, views or synonyms.

I thought that was strange, and so I searched over and over again and still I couldn't find it. Then I did a select statement the table that Access thinks exists and SQL Server does not show and to my shock, the select statement pulled in data!

So how did this happen? How can I find the object in SSMS folder listing of tables/views or whatever and what am I overlooking?

Thanks,
Keith

Deleting Data From DB

Nov 23, 2006

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?

Deleting From Sql Question.

Jan 2, 2007

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?
