How do I delete from multi tables?
There are no issues with keys.
Will this work?

Hi i have to delete the master table data without deleting the child table records,is there any solution for this, parent table has relation with the child table. regards vinod.t.v
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.
I am new to SQL server and have just installed SQL Server 2005 (came withOffice 2007- think it's Express edition).I am trying to get my head around this.Just been working on an Access data base and have upsized to SQL.Having made several changes I have done this a number of times - linkingboth direct to file and creating a new application Access SQL project.Now I would like to know how to delete any tables or databases I have placedon the SQL before my system gets too messy.Furthur information - This is on my personal computer and is not shared orused by other people.Any ideas?Scott
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.
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!
Is there a way to automatically delete tables in a database? I want to delete tables with a specific prefix in their names (that I assign to them) based on their age. Is there a way to do this automatically while keeping the tables that I don't want to touch?
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
Hi how can I delete a local temp table? I know a golbal is deleted by if exists(select * from tempdb..sysobjects where name='##MyTemGlobalTable' and type='U')drop table ##MyTemGlobalTable'
Hello all, I have a DTS package set up to import a text file on a daily basis.

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.
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?
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
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?
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.
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 FROM ih_cml_log_entry cml
I have a database with many tables. I would like to Delete all rows with practiceID=55 from all Parents tables and all corresponding rows from its child tables. Tables are linked with foreign key constraints (but there is no ON DELETE CASCADE).
How to write a generalized code for removing rows from both parent and child tables.
Query should pick parent table one by one and delete rows with practiceID=55 and all corresponding rows from its child tables

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?
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.
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 Must declare the scalar variable "@UserId".
