Impact Of Empty Tables On Database Size And Performance
Jun 21, 2007 Hello All,
When creating my database I have modeled some of the tables after the Adventureworks sample database.
There are some fields or entire tables in Adventureworks that I do not see an imediate use for, however; I would hate to ommit them to find out later they would have been benificial. (.eg territory table).
In general terms what would the impact be on size and performance of a database which contains tables or fields that do not contain data.
Thanks for your help!
Deleting From 2 Tables?
Jul 21, 2005Hi, I am pretty new to SQL and know that I am probably going around this the wrong way.
I want to make a stored proc that deletes rows from table 1 and delete rows from table 2 where the common link is the id.
Any help would be greatly appreciated!
Many thanks

Deleting Tables
Aug 24, 2005Does 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.

Deleting From 3 Tables
Apr 22, 2008Hello 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

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, 2006What 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, 2014I 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 type = 'U'

How To Return A List Of Empty Tables
Mar 19, 2003I want to return a list of user tables from a database where the rowcount is 0. This will be a 3 step process: (1) truncate all 'New%' tables, (2) load data via ODBC/DTS into 'New%' tables, (3) list all 'New%' tables with zero rows (i.e. those that didn't get loaded, as all tables in the ODBC data source contain data).
I've tried:
select left(s2.name,32) as TableName, max(s1.rows) as Records
from sysindexes s1
inner join sysobjects s2 on s1.id=s2.id
where type = 'U' and s2.name like 'New%'
group by s2.name
HAVING max(rows) = 0
ORDER BY TableName
but of course there are multiple rows in sysindexes and the routine does not reliably return the correct list; for example the data in sysobjects & sysindexes, without the max and group by, might look like:
TableNameRows
NewARTxn0
NewARTxn1214800
NewARTxn1214800
NewARTxn1214800
NewARTxn1214800
NewARTxn1214800
NewARTxn1214800
I was hoping to come up with a single T-SQL statement that I could use in an xp_sendmail situation to email me the results.
Thanks for the suggestions.

Empty Data Tables And Reload
May 6, 2015I would like to empty out my 2k8 database (remove all the data in the tables only) And reloaded it with the data from production (2k5). I know I would have to dis-enable any constraints, triggers and remove all indexes before I can run a Truncate/Delete on all tables correct And then import the data via Wizard or script And lastly enable all the constraints & triggers, rebuild the indexes. Is this the only way to go about this? I don't want to do a backup & restore because the 2k5 doesn't have a 20% of the tables that are in 2k8. The 20% of those tables in 2k8 i'm not going to remove.

Master Package - After Execution Empty Tables
Feb 12, 2008I'm running a master package executing 8 child packages.
Each package contains the same connection managers and each package is stored within the MSDB database.
The master package executes the packages stored in the MSDB using the 'execute package task'.
When running the master package from either MSDB or visual studio directly the odd thing happens that some tables will be filled, but after package execution I notice each table to be empty. There's no rollback 'procedure 'specified within the package and each package executes successfully because of error row handling. Anybody any hints how to solve this one?

Mar 1, 2005Hi,
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, 2006Hi 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, 2007I'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?

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.
