Problem with deleting connection from Connection Manager

Hallo,

I have deleted one of my file connection from Connection Manager (and

Executed ProcessTask which used it), however

trying to load the package I always get the error:

"Error loading MyPackage.dtsx: The connection "MyDeletedConnectionName" is not found.
This error is thrown by Connections collection when the specific connection element is not found."

I tried to Clean, Rebulid my project, but it doesn't help.

Does anybody know, how to solve it? Where this reference is saved?

Thank you.

Anna

Try to open the package XML in a text editor and look for that connection name.

HTH,

Bob

I am sorry, it was my mistake -

I forgot to delete the configuration file...

it works fine now.

Problem with Deletecomand attribute of asp:sqldatasource

Greetings everyone. I'm trying to set up a GridView that makes use of an SQL Datasource. All commands (update,select,delete) are set within the tag's attributes but when i hit the Delete Trigger it returns that the id variable is undeclared.

<asp:SqlDataSource
ID="KevinDataSource"
ConnectionString="Server=overmind;Database=kevin_bonis;User=sa;Password="
SelectCommand="SELECT * FROM Accesorii"
UpdateCommand="Update Accesorii SET nume_accesoriu=@.nume_accesoriu,

intors=@.intors,
data_intoarcere=@.data_intoarcere WHERE id=@.id"
DeleteCommand="DELETE FROM Accesorii WHERE id = @.id"

What could be the problem with this? I'll appreciate any help i can get.
Thanks alot, Allyrion

Hi Allyrion,

did you set the datakeynames property for Gridview?

Problem with delete, lock and transaction log

Problem with delete, lock and transaction log

we have problem with SQL Server 2000 SP3 / Windows 2003 EE
we have 10 huge tables, I have a procedure which deletes data from
these tables each day.
1. The deletes are very slow, it takes 20 min to delete 400,000
records. It does use index when it deletes, i have seen the plan
2. i am running the database in simple mode but still the transaction
log grows bigger and bigger during the delete process. I have used
checkpoint after every table delete but it didnt help. is there a way
we can avoid writing to transaction log so that i can solve this
problem and improve the delete performance too
3. If i stop the job then everything gets rolled back that is been done
by procedure. does it not commit table by table within the procedure?
is it waiting for the procedure to finish before it commits?
Can any one please help me ASAP
Thanks
RaghuAnswer for you questions:-
1. Disable the foreign key if you can do the house keeping after shutdown
the application [ See Alter table command]
2. No you can not avoid to log the transaction. The easy way is shrink the
transaction log fter delete [See DBCC SHRINKFILE]
3. That depends up the way you handle the transaction.. If its a single
delete statement inside the procedure and if you kill the job;
then automatically every thing pertaning to that delete will be rolled back
Thanks

I have no foreign keys on these tables. All i have is indexes to of
them one is for delete based on timestamp and other is for select which
includes 3 more columns.
DBCC SHRINKFILE is only after i do the delete, even before the delete
is finished my 100 GB transaction log is getting filled and stopping
all other application to either insert or delete data.
I have 10 delete statements so this mean that everything that it has
tried till that time is rolledback. I can do some kind of commit which
will clear the log as well as prevent the rollback if any problem
occurs. The begin and end transaction locks the table and wont allow to
make selects till it is commited, i want where selects can work when
delete is going on

You could use TRUNCATE TABLE, which is non-logged. Be sure to read the
Books Online entry first, there are some caveats to using this vs. DELETE.

Truncate table would clean the entire table. I am just trying to clean

I guess I missed that in your original post...

http://www.realsqlguy.com|||I have resolved one problem by splitting the job of delete into 2
different procedures where in the transaction log doesn't grow big now.
The performance of delete is still not improved it does take same
amount of time as mentioned. can anyone have any idea FYI
The deletes are too slow. it takes 20 min to delete 400000 records.

Problem with delete trigger

I am trying to write a delete trigger that fires when the user deletes the only record for a given entity in the table. In this situation I have an entity PMA which can have one or many uses. I want the trigger to fire if the user tries to delete the last use record for that PMA_NUM from the PMA_USE table.

Here is my code:

if (SELECT Count(pma_use.pma_num) FROM dbo.PMA_USE
inner join dbo.deleted as D1 on dbo.PMA_USE.PMA_NUM= d1.PMA_NUM) = 0
BEGIN
RAISERROR ('Cannot delete only Use for PMA!', 16, 1)
ROLLBACK TRANSACTION
END

I seem to be getting inconsistent results when I create the trigger and when I try to test it re the deleted table

Sometimes when I run the trigger script in Management Studio Express, it has trouble with my using dbo.deleted and sometimes it doesn't

When I try to test the trigger by using MSE to view the table and delete the last use record for a PMA, I get an invalid object cannot find 'dbo.deleted' or cannot find 'deleted'

What am I doing wrong?

Roberta

1 - Use just [deleted]

2 - you do not need to count in order to prove existence. Use EXISTS operator.

if exists(select * from dbo.PMA_USE as a innner join deleted as b on a.PMA_NUM = b.PMA_NUM)

BEGIN
RAISERROR ('Cannot delete only Use for PMA!', 16, 1)
ROLLBACK TRANSACTION
END

problem with delete statement

Hi guys,

i need some help on this issue, i have a table with a nvarchar type column with primary key constraint. I have made a procedure which deletes record from this table using the primary key. My primary key is TxnID, and when i ran the following statement:

DELETE from mytable where TxnID = '119DA-117440520'

it deleted the record with the id '119DA-1174405208'

I dont want this to happen, i only want to delete records with the exact IDs that i provide. Can any one tell me how i should do that?

Thanks in advance.

sorry! i managed to fix it...actually the width was not defined properly which was causing problem

sorry again

Problem with Delete On Linked Server

I am getting time-out errors when I try to perform a simple delete on a
linked server. The command is:

Delete From MyTable Where PKID=12345

I have tried executing this command directly from Query Analyzer, but it
just times out. However, when I run it from QA against the server itself
(rather than from my local server against a linked server), it executes
immediately. Similarly, if I run the same SQL command through an ODBC linked
table in an Access 2000 MDB file (tweaking the syntax slightly), it also
executes immediately. Only if I run it from SQL 7 as a stored procedure or a
QA command against a linked server does it time-out.

I have no problems inserting rows using any of the three methods noted
above. It is only with deleting rows through the linked server that it times
out.

Thanks for any assistance.

NeilCorrection: The syntax used against the linked server is the four-art
syntax:

Delete From svr.db.dbo.MyTable Where PKID=12345

Also, the same problem occurs with updates as with deletes (but not
inserts).

Thanks,

Neil

Another thing to see if it works - try executing the
statement using OpenQuery instead of the 4 part name and see
if that makes a difference.

In the meantime, I used OpenQuery as you suggested. This time at least I got
an error message (yea!), though somewhat cryptic:

"Could not process object 'Delete From images Where ImageID=99986'. The
OLE DB provider 'SQLOLEDB' indicates that the object has no columns."

Any ideas about what that means?

Thanks!

to the fact that Delete doesn't return rows, as OpenQuery is looking for.
So, per http://support.microsoft.com/defaul...b;en-us;Q270119, I
changed it to:

Delete OPENQUERY(abcweb, 'Select ImageID From images Where
ImageID=99987')

and it worked! Would still be good to find out why the original method
wouldn't work for deletes or updates, but did work for inserts. But at least
this works.
