Delete: Parameters From Another Table

Sep 27, 2006

DELETE FROM StoresViewToTable2
WHERE (AllZips = store1.AllZips) AND (StoreNo = store1.StoreNo)

I want to delete from StoresViewToTable2 where the fields match in another table (Store1). How do you get the where parameters to be from another table? is this possible? or do i just need to do an Outer Join. Im trying to avoid this becuase the StoresViewToTable2 tbl is very large.



StoresViewToTable2 (tbl)
AllZips | StoreNo

Store1 (tbl)
AllZips | StoreNo

How To Use Delete Parameters

Jun 4, 2006

Hey gang I am trying to use the delete feature of  a sqldatasource and having issues with the delete feature.    My code is below the issue is if I just call the delete and don't have a paramter in my delete statement then it deletes the records in my table.  However when I add a parameter to my delete query (@maID) and try to set it then it doesn't delete the record.  What am I doing wrong?  The e.CommandArgument is passing the correct record ID (which is an Integer).....can someone please help? 
PS I also tried without the @ symbol before my parameter and no luck either.
DELETE FROM tempMbrAccounts WHERE (maID = @maID) is my delete query  Public Sub OnDeleteButtonClick(ByVal sender As Object, ByVal e As GridViewCommandEventArgs) Handles gvEnterAcct.RowCommand
Dim RecID As Integer
If e.CommandName = "Delete" Then
RecID = e.CommandArgument
dsInsert.DeleteParameters.Add("@maID", RecID)
dsInsert.Delete()
tempAcctTable()
End If
End Sub

When I debug my code I see the string going into the parameter correclty, but the the delete statement doesnt work and I'm not sure why. Does this look ok?  // Set up SqlCommand, connection to db, sql statement, etc.
SqlCommand DeleteCommand = new SqlCommand();
DeleteCommand.Connection = DBConnectionClass.myConnection;
DeleteCommand.CommandType = CommandType.Text;

// Store Primary Key photoID passed here from DeleteRows_Click

DeletePrimaryKeyParam.ParameterName = "@PhotoID";
DeletePrimaryKeyParam.Value = photoID.ToString();

// Insert new parameter into command object

Copy And Delete Table With Foreign Key References(...,...) On Delete Cascade?

Oct 23, 2004

Hello:
Need some serious help with this one...

Background:
Am working on completing an ORM that can not only handles CRUD actions -- but that can also updates the structure of a table transparently when the class defs change. Reason for this is that I can't get the SQL scripts that would work for updating a software on SqlServer to be portable to other DBMS systems. Doing it by code, rather than SQL batch has a chance of making cross-platform, updateable, software...

Anyway, because it needs to be cross-DBMS capable, the constraints are that the system used must work for the lowest common denominator....ie, a 'recipe' of steps that will work on all DBMS's.

The Problem:
There might be simpler ways to do this with SqlServer (all ears :-) - just in case I can't make it cross platform right now) but, with simplistic DBMS's (SqlLite, etc) there is no way to ALTER table once formed: one has to COPY the Table to a new TMP name, adding a Column in the process, then delete the original, then rename the TMP to the original name.

This appears possible in SqlServer too --...as long as there are no CASCADE operations.
Truncate table doesn't seem to be the solution, nor drop, as they all seem to trigger a Cascade delete in the Foreign Table.

So -- please correct me if I am wrong here -- it appears that the operations would be
along the lines of:
a) Remove the Foreign Key references
b) Copy the table structure, and make a new temp table, adding the column
c) Copy the data over
d) Add the FK relations, that used to be in the first table, to the new table
e) Delete the original
f) Done?

The questions are:
a) How does one alter a table to REMOVE the Foreign Key References part, if it has no 'name'.
b) Anyone know of a good clean way to get, and save these constraints to reapply them to the new table. Hopefully with some cross platform ADO.NET solution? GetSchema etc appears to me to be very dbms dependant?
c) ANY and all tips on things I might run into later that I have not mentioned, are also greatly appreciated.

Thanks!
Sky

Delete Syntax To Delete A Record From One Table If A Matching Value Isn't Found In Another

Nov 17, 2006

I'm trying to clean up a database design and I'm in a situation to where two tables need a FK but since it didn't exist before there are orphaned records.

Tables are:

Brokers and it's PK is BID

The 2nd table is Broker_Rates which also has a BID table.

I'm trying to figure out a t-sql statement that will parse through all the recrods in the Broker_Rates table and delete the record if there isn't a match for the BID record in the brokers table.

I know this isn't correct syntax but should hopefully clear up what I'm asking

DELETE FROM Broker_Rates

WHERE (Broker_Rates.BID <> Broker.BID)

Thanks

Need Help W/ Postback To 'Customers' Table On Form Using Select Query From 'Parameters' Table

Dec 20, 2007

I have set up a 'Parameters' table that solely stores all pre-assigned selection values for a webform. I customized a stored query to Select the values from the Parameters table. I set up the webform. The result is that the form1.apsx automatically populates each DropDownList task with the pre-assigned values from the 'Parameters' table (for example, the stored values in the 'Parameters' table 'Home', 'Business', and 'Other'  populate the drop down list for 'Type').
The programming to move the selected data from form1.aspx to a new table in the SQL database perplexes me. If possible, I would like to use the form1.aspx to Postback (or Insert) the "selected" data to a *new* column in a *new* table (such as writing the data to the 'CustomerType' column in the 'Customers' table; I clearly do not want to write back to the 'Parameters' table). Any help to get over this hurdle would be deeply appreciated.

Delete Rows In One Table By Referencing Another Table Info

Sep 16, 2004

I have one table that has unique id's associated with each row of information. I want to delete rows of information in one table that have a unique ID that references information in another table.

Here is a basic breakdown of what I am trying to do:

Table1 (the table where the rows need to be deleted from)
Column_x (Holds the id that is unique to the various rows of data - User ID)

Table2 (Holds the user information & has the associated ID)
Column_z (holds the User ID)

I tried this on a test set of tables and could not get it to work. What I am trying to do is skip all rows of Table1 that have ID's present in Table2, and delete the rows of ID's that are not present in Table2.

Code:


SELECT Column_z
FROM dbo.Table2
DELETE FROM dbo.Table1
WHERE Column_z <> Column_x


This did not seem to do what I needed, it did not delete any rows at all.

I wanted it to delete all rows in Table1 that did not have a reference to a user ID that matched any ID's in Column_z of Table2

Then I tried another scenerio that I also needed to do:

Code:


SELECT Column_z, Column_a
FROM dbo.Table2
DELETE FROM dbo.Table1
WHERE Column_z = Column_x AND Column_a='0'



'0' being the user id is inactive so I wanted to delete rows in Table1 and remove all references to users that were in an inactive status in Table2.

Neither one of the Queries wanted to work for me in the Query Analyzer when I ran them. It just said (0) rows affected.

Any ideas on what I am doing wrong here?

Newbie-DELETE A Record In A Table A That Is Related To Table B, And Table B Related To Table A

Mar 20, 2008

Hi thanks for looking at my question

Using sqlServer management studio 2005

My Tables are something like this:

--Table 1 "Employee"
CREATE TABLE [MyCompany].[Employee](
[EmployeeGID] [int] IDENTITY(1,1) NOT NULL,
[BranchFID] [int] NOT NULL,
[FirstName] [varchar](50) NOT NULL,
[MiddleName] [varchar](50) NOT NULL,
[LastName] [varchar](50) NOT NULL,
CONSTRAINT [PK_Employee] PRIMARY KEY CLUSTERED
(
[EmployeeGID]
)
GO
ALTER TABLE [MyCompany].[Employee]
WITH CHECK ADD CONSTRAINT [FK_Employee_BranchFID]
FOREIGN KEY([BranchFID])
REFERENCES [myCompany].[Branch] ([BranchGID])
GO
ALTER TABLE [MyCompany].[Employee] CHECK CONSTRAINT [FK_Employee_BranchFID]

-- Table 2 "Branch"
CREATE TABLE [Mycompany].[Branch](
[BranchGID] [int] IDENTITY(1,1) NOT NULL,
[BranchName] [varchar](50) NOT NULL,
[City] [varchar](50) NOT NULL,
[ManagerFID] [int] NOT NULL,
CONSTRAINT [PK_Branch] PRIMARY KEY CLUSTERED
(
[BranchGID]
)
GO
ALTER TABLE [MyCompany].[Branch]
WITH CHECK ADD CONSTRAINT [FK_Branch_ManagerFID]
FOREIGN KEY([ManagerFID])
REFERENCES [MyCompany].[Employee] ([EmployeeGID])
GO
ALTER TABLE [MyCompany].[Branch]
CHECK CONSTRAINT [FK_Branch_ManagerFID]

--Foreign IDs = FID
--generated IDs = GID
Then I try a simple single row DELETE

DELETE FROM MyCompany.Employee
WHERE EmployeeGID= 39

Well this might look like a very basic error:
I get this Error after trying to delete something from Table €œEmployee€?


The DELETE statement conflicted with the
REFERENCE constraint "FK_Branch_ManagerFID".
The conflict occurred in database "MyDatabase",
table "myCompany.Branch", column 'ManagerFID'.

Yes what I€™ve been doing is to deactivate the foreign key constraint, in both tables when performing these kinds of operations, same thing if I try to delete a €œBranch€? entry, basically each entry in €œbranch€? and €œEmployee€? is child of each other which makes things more complicated.

My question is, is there a simple way to overcome this obstacle without having to deactivate the foreign key constraints every time or a good way to prevent this from happening in the first place? Is this when I have to use €œON DELETE CASCADE€? or something?

Thanks

Need To Delete A Table Which Has A Reference To Another Table

Dec 12, 2007

Hi Friends...

In general we cannot delete a table if it refers another table. But in the process of backup and restore, we need to delete all the tables, so we have return an asp.net function...

Dim Datatable As String
Dim ds As New DataSet
ds = gDatabase.ExecuteQuery(" select Table_Name from Information_schema.Tables where Table_type='TABLE'")
If ds.Tables.Count > 0 Then
If ds.Tables(0).Rows.Count > 0 Then
Dim dr As DataRow
Dim da As SqlCeDataAdapter
Dim Cmd As String
For Each dr In ds.Tables(0).Rows
Datatable = dr.Item("Table_name")
Cmd = "Delete from [" & Datatable & "]"
gDatabase.ExecuteNonQuery(Cmd)
Next
End If
End If

we got an error like

"Msg 4712, Level 16, State 1, Line 1
Cannot truncate table 'Electricalworks' because it is being referenced by a FOREIGN KEY constraint.
"

how to override these errors, if we have to delete all the tables. We have about 200 tables.

Delete Record From Table A That Is Not In Table B

Apr 2, 2008



I have two tables;
Table A
id, name
101, jones
102, smith
103, williams
104, johnson
105, brown
106, green
107, anderson

Table B
id, name, city, state

103, williams, Corvallis, Oregon
104, johnson, Grand Forks, North Dakota
105, brown, Phoenix, Arizona
107, anderson, New York, New York

I need to delete records from Table A that are not in Table B. My front end is writen in .net and I am using Data Access Layer along with a Business Logic Layer for data interaction.

I have tried at least seven variations of joining, right outer join, left outer join resulting in wiping our the entire table or nothing at all; not to mention deleting the record that ought to remain and keeping the record that needs to be deleted!

In my BLL I tried to capture the rowsAffected for the deletion by using-without success.

Dim rowsAffected As Integer = Adapter.ID_Deletion(ID)

If rowsAffected = 1 Then

Exit Function

Else

Return rowsAffected = 1

End If

Please help.

4G Table's Delete Uses 20G Log???

Apr 3, 2008



I've a table with a size of ~4G and 6million rows in SQL server 2005.
Deleting all rows from it it takes closer to an hour and uses
~20G of transaction log. I wasn't able to truncate it due to FK's, but
should I not be able to truncat it by disabling FKs - how can I do
that? Or how can I expedite this delete because it;s annoying to let
server use 20G log for 4G table. My DB recovery model is set to SIMPLE
(for minimum logging)

Cannot Delete A Row In A Table

Mar 25, 2007

I have a table in a SQLEXPRESS database that I read in C# app. It supposed to have only two rows but a number of fields with Float or Int type parameters. It is a tedious process to tune them all up in the app. The table is used for storage, naturally.

For some reason, I won't go into I ended up with having 3 rows in this table at this point. This third row is identical to the first one in the values of all fields. It happened because I deleted a column that made these rows not unique and after that the trouble began. Before deletion of that column I had 4 rows, then I deleted the 3rd one and row #4 moved in place of #3.

For the life of me I cannot delete this 4th row no matter what I do. It gives me an error:

No rows were deleted. Problem occured while deleting row1 (sic!, I am trying to delete row #3 in fact). The row values updated or deleted either do not make the row unique or they alter multiple rows (2 rows).

Good grief! This is why I am trying to delete this row!

It does not allow me to edit the fields to change the values to make them not unique. The same error pops up. It does not allow me to change the values of the first row which is identical to the third one.

It is not the first time this happened. I had it once or twice before. Back then I had to truncate the table and enter new values from scratch I am kind of tired of doing it.

What is the way to handle this strange behavior?

Thanks.

So, if I have:

Currently I have them set as a 1-M from tblClients to tblClientAddressLinks and a 1-M from tblClientAddresses to tblClientAddressLinks
If I try and delete a client and there address is shared wont this go very wrong?
So here is what happens when I try and delete a client:
The DELETE statement conflicted with the REFERENCE constraint "FK_tblClientAddressLinks_tblClients". The conflict occurred in database "DBSQL2", table "dbo.tblcLIENTAddressLinks", column 'clientID'.The statement has been terminated.
Here is what happens when I try and delete an address:
