I have added a delete button to my datagrid, and put in what I think is the code to delete a member from the database at their Member ID, however when I have called a members details and the delete button is pressed, nothing happens!!??
Any ideas?
Here is the code:
<%@ Page Language="VB" %>
<script runat="server">
' Insert page code here
'
Function GetMember(ByVal iD As Integer) As System.Data.SqlClient.SqlDataReader
Dim connectionString As String = "server='localhost'; trusted_connection=true; Database='adp1SQL'"
Dim sqlConnection As System.Data.SqlClient.SqlConnection = New System.Data.SqlClient.SqlConnection(connectionString)
Dim queryString As String = "SELECT [oga].* FROM [oga] WHERE ([oga].[ID] = @ID)"
Dim sqlCommand As System.Data.SqlClient.SqlCommand = New System.Data.SqlClient.SqlCommand(queryString, sqlConnection)
sqlCommand.Parameters.Add("@ID", System.Data.SqlDbType.Int).Value = iD
sqlConnection.Open
Dim dataReader As System.Data.SqlClient.SqlDataReader = sqlCommand.ExecuteReader(System.Data.CommandBehavior.CloseConnection)
Return dataReader
End Function
Sub dgMember_Delete(sender as Object, e as DataGridCommandEventArgs)
dgMember.EditItemIndex = -1
dgMember.DataSource = GetMember(memberID.Text)
dgMember.DataBind()
End Sub
Sub btnView_Click(sender As Object, e As EventArgs)
dgMember.DataSource = GetMember(memberID.Text)

I am trying to delete tables from data where the ModifiedDates older than 9 years in AdventureWorks2012 database . I get console notified that foreign keys are dropped but the delete statement is throwing errors. I am sure that somewhere the key constraints are not getting altered, but i'm not able to figure it out as i'm a relative beginner to T-SQL. The error and code:
The DELETE statement conflicted with the REFERENCE constraint "FK_SalesOrderHeaderSalesReason_SalesReason_SalesReasonID". The conflict occurred in database "AdventureWorks2012", table "Sales.SalesOrderHeader [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.SMO") | Out-Null $option_drop = new-object Microsoft.SqlServer.Management.Smo.ScriptingOptions; $option_drop.ScriptDrops = $true;
I don't know if the question has been nailed down. Aside from deleting tables, can we delete the *content* of data within the tables. It doesn't seem crazy that, if you can pull in data from a feed then you should be able to remove the content out again (without also destroying the user's meta-data work ). Reasons for this include:
- Security (a user may not have rights to see *my* data and should go refresh their own) - Size (workbook doesn't need to have GB's of irrelevant data saved to disk in a workbook if it was just useful during development phase to a pre-production data feed) - Bad data (pre-production data feed is not good data) - User-friendliness (data feed was refreshed 2 years ago and workbook was saved to file server. Users shouldn't be presented with irrelevant data, but should get empty pivot tables until they go do their refresh)
Obviously Excel internally knows how to clear out PowerPivot data, given the prompt shown here: [URL] ....
But how does a user initiate this on their own (corruption aside)?

We are running SQL Server 2005 express on Windows 2003. The database server gets significant amounts of data.
Because of the 4GB data limit we have a daily cron task which goes through and deletes data older then 90 days.
We would like a way to archive this data instead of deleting it. Is there any way to take data and compress it and store it in a different way, so that if needed, customers can query directly out from the compressed data? Cleary querying from compressed would be slower but that is ok.
Any other solutions that would allow us to archive data instead of deleting it? Thanks.
I have a package which loads data from a flat file (csv) to 4 tables in a database. Now, the load is incremental.
I want to clear the data of all 4 tables(in the database) before loading the data from flat file everytime.How can i do this? Iam using 4 Oledb Destinations, 1 multicast, 1 source component to do this. Also can it happen like a transaction? because if it deletes the existing data and couldnt load new data there will be a problem!.how to avoid this?
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
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?

Hi. I'm starting to try out LINQ to SQL, and so I'm using SQL Express (on Vista) to experiment. My problem is that once I create and delete a database, I can never use the name again. If, after deleting the old database, I try to create another one with the same name (say Acct1), I get "Create failed for Database 'Acct1'. An exception occurred while executing a Transact-SQL statement or batch. The logical file name "Acct1" is already in use. Choose a different name. Error: 1828"
I am trying to create the database in SQL Server Management Studio Express. That database name does not appear in the list of databases: there is only AdventureWorks and the system databases. The .MDF and .LDF files have been deleted. Not just sent to the recycle bin, but permanently deleted.
I have already used up Acct1, Acct2, and Acct3, just to try out different scenarios. Each time, I delete the old database before trying to create a new one with the same name, but I am forced to always supply a new, different name. I have checked the directory with hidden files and system files showing to be sure there is no old file lurking there somewhere.
Is there a way to delete these old "logical file names"? I can't even find any reference to their existence except for the message that says they are already in use.
I have recently installed SQL server 2005 express edition along with Sql server management studio expressI have run the installation twice and during the installation I have created two instances of SQL server one named instance having Windows authentication and the other default instance having mixed mode authentication. Now I want to delete the named instance. Could anybody tellme I can delete the named instance?
my row in my data base consists of 12 coulmns, i have a duplicate values in 6 coulmns of it , i use select distinct for all it doesnt work for it it doesnot remove dupliacte , i cant make primary key or any constraint on this 6 coulmns together cause it contains duplicate values even if i choose ignore duplicate it doesnot work
example id name adress telephone job gender deprtment 1 john dd 123 doctor m 1st deprtment 1 john dd 123 doctor m 2nd deprtment
so there is duplicate on id, name,telephone, job , gender and different in department so how i make a primary key on id , name , adress , telephone , job , gender together
also how to delete duplicate from it although i used distinct function and it doesnit remove duplicate
I have an old DATABASE that is not more in use , so I want to drop that database. But before that I want to check that is there any application running on it or not.
I have been trying to develop a simple delete operation in VB using a local SQL Express database located inside the project. My selects, inserts, and updates are working ok, but for some reason my delete doesn't want to work.
I have the database file set to "copy if newer" in the properties and am only using a simple parameterized query to delete. I am not using an bound controls like datagrid and even when I do, the same problem occurs. I am also not using a dataset object.
I have setup a SqlConnection object and a SqlCommand object in my code. The command is set to the Sql text of
Code Snippet DELETE FROM Providers WHERE (PaymentDate BETWEEN @StartingDate AND @EndingDate)
In my Database, I have a field called ID which is the primary key and is set as an identity field. PaymentDate is a datetime value and the two parameters "@StartingDate and @EndingDate" are also datetime values passing only the date value from a datetimepicker control in VB.
Anyway, when I run the code, and even when I pass a return value back, it shows it deleted the record without any errors. However, I normally have a query window open selecting all records and before closing the program, I refresh this query and no changes have occurred. The record I tried to delete is still there.
I have tried several time and using several different method (Stored Procedures, databound controls, ete) and am getting the same result each time.
In asking this question in the MSDN VB Forums since I figured it was more than likely a VB problem and not a SQL issue, I was eventually directed here.

I wrote a script to archive and delete records rom a table back in 2005 and 2009.
I can't seem to get the syntax right. Any sample script to simply archive and delete records?
This is what I have so far.
DECLARE @ArchiveDate Datetime SET @ArchiveDate = (SELECT TOP 1 DATEPART(yyyy,Call_Date) FROM tblCall ORDER BY Call_Date) --SELECT @ArchiveDate AS ArchiveDate DECLARE @Active bit
I have to delete a ton of data from a SQL table. I have a unique identifier called the version. I would like to use if not in these versions then delete. I tried to using the statement below, but learned the hard way that it created an error this is the message I got....

I really don't know how frowned upon my approach is here, but it was the only way I have been able I've been able to do it.
On my application, when users delete their account, it sometimes brings the db server to a COMPLETE crawl. The reason is some users who delete have many years of related data, and when the data deletes with them, its very slow.
To avoid this I've taken off many contstraints, and I do have some sprocs that deleted orphaned data at night.
The data is automaticaly deleting from one perticular table at every night from last week onwords. I have created a delete trigger to find it out. But Nothing was recorded. There is no jobs except maintainance plans. Nothing in event viewer too. The database recovery model is simple. How can i solve this problem Please advise me to solve this problem
I have an entry form allowing customers to enter up to 15 skus (productid) at a time, so they can make a multiple order, instead of enteringone sku, then submitting it, then returing to the form to submit thesecond one, and so forth.From time to time, the sku they enter will be wrong, or discontiued, soit will not submit an order.Therefore, when they are done submitting their 15 skus through the orderform, I want a list showing them all of those skus that came back blank,or were not found in the database.I'm doing this by creating two tables. A shopping cart, which holds allthe skus that were returned, and a holding table, that holds all theskus that were submitted. I want to then delete all the skus in theholding page that match the skus in teh cart (because they are goodskus) which will then leave the unmatched skus in the holding table.I'll then scroll out the contents of the holding table, to show them theskus that were not found in the database.(confused yet?)So what I want to do is have some sql that will delete from the holdingtable where the sku = the sku in the cart. I've tried writing this, butit dosn't work.I tiried this delete from holding_table where sku = cart.skuI was hoping this would work, but it dosn't. Is there a way for me to dothis?Thanks!Bill*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!
I have a table that contains more than 10,000 rows of duplicate data. The script below copies the data to a temp table then deletes from the original table. My problem is that after it runs, I now have 122 rows of triplicate data (but dups are gone). If I rerun the script, it doesn't see the triplicate data and returns 0 rows. I've use three different versions of delete dup row scripts with the same result. There are no triggers or constraints on the table, not even a primary key. What am I missing?-------------------------------------------------------------------

I can run a select to retrieve data using a prefix 'a' for the specific table involved. However when I try to run a delete using the same criteria it fails telling me
Msg 102, Level 15, State 1,.......Line 1
Incorrect syntax near 'a'
The Select statement looks like:
select count(*) from schema.table a where a.customer_id=1234
The Delete looks like:
delete from schema.table a where a.customer_id=1234
What am I doing wrong here? and how can I prefix the table, because the command I want to run is much more complicated than the example above and it needs the prefix
When I delete substantial amounts of data using the SQL DELETE command, the database size apparently remains the same (702 mb) and the log file goes from about 17 mb to over 1 gig. I was expecting for the overall size to decrease drastically, but got just the opposite.
Is this typical? Can I do something to slim it down? As I am just trying to decrease the overall size to make it easier to work with when creating my application in VB, I am not worried about restoring the db (I have secure copies).
Hi All, I have to delete 135 Million records from our production server, keeping only last three months data & the table doesnot have any index.
Can you please suggest the best possible approach to perform this activity.
Approach i am thinking :-
1)I will rename the existing table & create a new table with the same name (By this my application wont be interrupted) 2)then i am planning to create a nonclustered index on the date column sort order desc so that i can get the last three months data. 3)Once the index is created i can transfer the required records to the new table created in step 1.
Please sugeest your valuable feedback or suggestions to perform the task ASAP.
I'm trying to delete some records from some tables in a SQL Server 2008 R2 database. There's a foreign key relationship between the two tables. To make things easier here's the definition of both tables:
