Hi,
Whenever I add a new VS auto-generated class they are created as Public by default. Is it possible to make some of the classes internal by default?
If I edit the code manually it will get auto-generated when I change the dataset, which I don't want to happen.
Any help much appreciated.

There are 152 unique reasons for a transaction to fail fatally. Which would you like to discuss?

If they are obvious then surely you should have notice them already. If they are common surely you should have received a message already.
This is obviously a homework question. And the most common response is that you should attempt to do the work yourself and if you have any specific problems then come back and we'll help you out. You have to show you are at least willing to study on your own.

Hi all,
I got a problem with running distributed transactions between two servers that is connected via VPN connection (using RRAS).
after the VPN connection is connected I can connect to the remote server with Microsoft SQL server management Studio and I can run query againts server.
The problem occures when one of my store procedures start a distributed transaction and wants to insert at the remote server. (with just one insert command I can insert rows in the remote server but I can not wrap in a transaction) I got this error :
"OLE DB provider "SQLNCLI" for linked server "172.26.0.11\CENTER" returned message "No transaction is active.".
Msg 7391, Level 16, State 2, Procedure p_InsertPointOnline, Line 54
The operation could not be performed because OLE DB provider "SQLNCLI" for linked server "172.26.0.11\CENTER" was unable to begin a distributed transaction."
I tried the following things :
1. turn off firewall in both sides.
2. Checking MS DTC security to allow outbound an inbound transactions on both sides
3. SET XACT_ABORT ON
4. SET REMOTE_PROC_TRANSACTIONS ON
the strange thing is when I switched the firewall off and reconnect the VPN I got some transactions through. But the day after that the system did not work, after a lot of time I again turn the firewall back on with some added port as exceptions. Again it works until I disconnect the VPN and reconnect. I again turn the firewall off and reconnect the VPN it works again, you see the loooop  !!!
if any one could help me with this issue I would be gratefull.
Hope you never stuck in such situations.

Check which ports your firewall are blocking.

The firewall on both sides are off.
I discovered the reason but the do not know what to do exactly.
The thing is that the remote server which is VPN server can not use netbios to reply to local server it can not resolve the Computer name. after the connection is made it is for about two seconds can reslove the name but after that it stop.
I you know beside firewall what can cause such problem do not hesitate to tell me.
Extra information :
the remote server is win2003
local server is Winxp Pro
both have sql 2005 standard edition
No firewall software is installed and windows firewall is off.
Thanks

hi friends,
I want a delete query to delete rows from multiple tables. but all the tables containg one command field as 'id'. and the deletion based on some input given to this common field at run time in msaccess. Please help. I am trying like this. But it gives Could not delete message.
DELETE contact.*, address.*
FROM contact, address
WHERE contact.consultantid=[@consultantid] and address.consultantid=[@consultantid];
Thanks in advance.
Regards,
Prya

You cannot perform a delete on two tables at once. You can perform two deletes, and this is what you should do.

also you could set up cascading deletes and then if you delete from one table the record gets removed from the related table. I'm never sure how much i like cascading deletes though. Pete's method is the one i would use in my code you can pass the two commands separated by ; if you only want to make 1 call (i believe)

You also need to be careful about the order of the delete statements if you are using foreign key constraints. In this case, you would need to delete from the address table before the contact table.

declare @ID as int<br />
set @ID=41 --instad 41 use parameter<br />
DELETE FROM contact WHERE ID =@ID<br />
DELETE FROM addressWHERE ID =@ID

If you are using SQL Server you can write a FOR DELETE trigger on the table 'contact'. Try this: -
--------------------------------------------------------------------------------------------------
CREATE PROCEDURE DeleteContact @consultantid int
AS
DELETE FROM contact WHERE consultantid=@consultantid
--------------------------------------------------------------------------------------------------
Now create a trigger on the table 'contact': -
--------------------------------------------------------------------------------------------------
CREATE TRIGGER DeleteAddress ON contact
FOR DELETE
AS
CREATE TABLE #DeletedContacts
(
consultantid int
)
INSERT INTO #DeletedContacts SELECT consultantid FROM deleted
DELETE FROM address WHERE consultantid IN (SELECT consultantid FROM deleted)
--------------------------------------------------------------------------------------------------
Now, you execute the stored procedure: EXEC DeleteContact <anyconsultantid>
After it deletes from the table 'contact' the trigger will be excuted and it will delete corresponsing rows from the table 'address'.

Hy,

Where I can find model's of plan maintenance for medium database (300 000 records per year) ?
Any ideas.

I have no idea what you mean by "table creation wizard". However, in both the design view and the diagram view you can select multiple columns then right click and select "Primary Key" from the menu.

Have a look in the SQL server Books On Line (look up CREATE TRIGGER in the index, it will give you all the details and a few examples)

Hey all,
how do I update table1 depending on its relation with table2 and table3?
eg.,
UPDATE table1 SET table1.col1 = (SELECT table4.col1 FROM table4 WHERE table4.col2 = "asdfgf" ) WHERE table1.col2 = table2.col1 AND table1.col3 = table3.col1
Is the above correct?
Or should I use JOIN to do the above? If so, how do I do it?
Can anyone help?
Thanks in advance.

As far as my knowledge goes, I guess the above query should work as expected. A join is not needed in this case. A join is needed only when you need to combine data from multiple tables based on certain criteria.

Can anybody help ?
This is ASP.Net code
I'm trying to send Null value to stored procedure

...
cmdInsert.Parameters.Add( "@test_var", DBNull.Value )
...
Question
How this can be done with old ASP code
If I try something like this I got error
...
Set objParam = objComm.CreateParameter("@test_var", adVarChar, adParamInput, Len(test_var), Null)
objComm.Parameters.Append objParam
...
How can I do this?
Is there in old ASP code something like "DBNull.Value" in ASP.Net
Thank u

I think you get the prize for the most vague question of the day.
What database are you using? Is it a commerial offereing? If yes then it may already have .NET providers. Is it a database engine you created yourself? Then you will have to read up on Data Providers (The interefaces in the System.Data namespace will be a good referrence)

I have two database : Db1 and Db2
I want to fill tables of Db2 with some fields of Db1 tables
also I do`nt want to use from Import & Export wizard
do you have any idea
Hello Friends

If they're on the same server, you can prefix the owner.tablename with the database. So, suppose that you had Database1.dbo.MyTable and Database2.dbo.MyTable, you could do the following (as an example):
INSERT INTO Database2.dbo.MyTable<br />
SELECT * FROM Database1.dbo.MyTable
Obviously, you will need the relevant permissions in both dbs to do this.

My database table consists a Field (Called ApplyDate)store the integer data, like "20061122" represent 22 nov 2006. i need to filter the data for whole November 2006, but if i write SELECT....WHERE ApplyDate = 200611 , it cannot get the data out because the last two digit no specified. So , how i write the SQL Where statement if i want to select Whole Nov 2006 ? (for example, 20061101...20061130 also acceptable)
Best regards,
Chee ken
