I have created a win service which executes a long latency SQL Server stored procedure. The service sits on a different server than SQL Server. If the win service server unexpectedly crashed right after I have called the stored procedure, would the stored procedure continue its execution or fail because the connection was lost?

I'm trying to run the following ODBC command. It's returning 0 when I'm expecting a positive integer. Can anyone see where I'm going wrong?
ok=DBC (PREPARE, db_conn, "SELECT c.QuestionID FROM (SELECT DISTINCT QuestionID FROM Questions WHERE TopicID = ?) AS c LEFT OUTER JOIN (SELECT DISTINCT QuestionID, UserID FROM UserResponses WHERE UserID = ?) AS d ON c.QuestionID = d.QuestionID WHERE d.UserID <> ? OR d.UserID IS NULL ORDER BY c.QuestionID": db_stmt)
I am (fairly) confident that the SQL is correct as it is performing as expected when tested in Visual Web Developer.
Thanks,
Alice

In my ASP.NET.net site ,I sometimes(but not always) get this error :
Timeout expired.The timeout period elapsed prior to completion of the operation or the server is not responding.
I think its sql server error . Someone tell me how I can solve this problem.
I need urgent help .

There are a number of options:
1. Increase the timeout. See SqlCommand.CommandTimeout
2. Check the hardware configuration of your SQL Server can handle the loads you are applying to it.
3. Check your code for performance bottlenecks.

First you need to identify the query that is throwing the timeout exception. Once you've identified the query, you can see if it is possible to optimize the query. If not, you can try setting the SqlCommand CommandTimeout[^] to a longer number of seconds.

I have some tables
AccountTypes (1:m)Accounts (1:m)Transaction
AccountTypes
------------
ATypeID AType
---------------------
01 Expanses
02 Advance to Contractors
.
.
.
10 Banks, Sundry Accounts
Accounts
--------
AType AC AName OpDr OpCr Date
----------------------------------------------------------
01 001 Advertisements 0.0 100.0 20/10/2006
..
.

.
Transaction
-----------
VType VNo Date TsDesc AType AC Debit Credit
--------------------------------------------------------------------------------------
CP 101 20/10/2006 paid for newspapers 01 001 100.0 0.0
now I want to see all AType,whether their against transaction are occured or not, their Opening Credit and debit
(OpDr & OpCr) and sum of credit of all transaction against that Atype and Acode (AC).
My query only returns records of those which against some transaction are occured. But I also want to include
Opening Cr and Dr in my Reports for trial Balance.
My Query is this:
SELECT AccountTypes.ATypeID, AccountTypes.AType, Accounts.OpDr + SUM([Transaction].Debit) AS TDr, Accounts.OpCr <br />
<br />
+ SUM([Transaction].Credit) <br />
AS TCr<br />
FROM Accounts INNER JOIN<br />
[Transaction] ON Accounts.ATypeID = [Transaction].ATypeID AND Accounts.AC = [Transaction].AC <br />
<br />
INNER JOIN<br />
AccountTypes ON Accounts.ATypeID = AccountTypes.ATypeID<br />
GROUP BY Accounts.OpDr, Accounts.OpCr, AccountTypes.AType, AccountTypes.ATypeID<br />
I think there is some join Problems, Left join may be work.
but can any one help me.
Thanks

Hi Syed
You need to use an outer join:
SELECT AccountTypes.ATypeID, AccountTypes.AType, Accounts.OpDr +<br />
SUM([Transaction].Debit) AS TDr, Accounts.OpCr +<br />
SUM([Transaction].Credit) AS TCr<br />
FROM Accounts<br />
LEFT OUTER JOIN [Transaction]<br />
ON Accounts.ATypeID = [Transaction].ATypeID<br />
AND Accounts.AC = [Transaction].AC <br />
INNER JOIN AccountTypes<br />
ON Accounts.ATypeID = AccountTypes.ATypeID<br />
GROUP BY Accounts.OpDr, Accounts.OpCr, AccountTypes.AType, AccountTypes.ATypeID
Inner join only reports results where both of the source tables have matching rows - so you would only see accounts that have one-or-more transactions. Using an outer join means that you can see accounts that have no transaction too.
Hope this helps.

You can use Enterprise Manager (if you have SQL 2000), or SQL Server Management Studio (if you have SQL 2005) to import your data (tables, columns, records) from MySQL.
The wizard to do import/export data should be simple enough to follow.

I've got a fairly simple bit of code which will call a stored proc with the following signature:
dbo.UpdateAssembler (@Id int, @Name char(20), @IsActive bit, @Stamp timestamp) I've created and initialized an SqlCommand object with the appropriate parameters setup, the relevant one in this case "Id" has it's IsNullable property set to true. When I try and execute the command I get the following exception:
Procedure or Function 'UpdateAssembler' expects parameter '@Id', which was not supplied. Hmm  , I've set Id in the previous lines of code (which could be an int or null, the stored proc does something different if Id is null).
Any ideas on what might be causing this exception, note that I have verified the following:
- A parameter by the name of 'Id' does exist in the command's parameters (C# side of things)
- Stored proc does want an Id parameter
- The stored proc works fine if I invoke it through the UI in either VS2005 or the Management Studio.
Sig cops got me...

Okay... But it is looking for a parameter called @Id. Do you supply that parameter?
You might want to post your code - It sounds like a really simple thing like a typo you just need a second pair of eyes to see.

Hmm, I seem to remember the last time I did something like this it didn't want the @ in the SqlParameter's name, but I shall check it, then I'll post the code if not successful since it's taking an age for VS to load.
Sig cops got me...

Ok here's the code (putting the @ in made no difference)
Stored Procedure:
ALTER PROCEDURE dbo.UpdateAssembler (@Id int, @Name char(20), @IsActive bit, @Stamp timestamp) AS
BEGIN
IF EXISTS(SELECT * FROM Assembler WHERE ID = @Id)
IF EXISTS(SELECT * FROM Assembler WHERE (ID = @Id AND Stamp = @Stamp))
UPDATE Assembler
SET Name = @Name,
IsActive = @IsActive
WHERE ID = @Id
ELSE
RAISERROR('Different TimeStamps',10,1)
ELSE
INSERT INTO Assembler
(Name, IsActive)
VALUES (@Name, @IsActive)
ENDBuilding the SqlCommand (in a semi-factory like method thingy-ma-bob):
SqlCommand command = new SqlCommand("UpdateAssembler");
command.CommandType = CommandType.StoredProcedure;
command.Parameters.Add("Id", SqlDbType.Int);
command.Parameters.Add("Stamp", SqlDbType.Timestamp);
command.Parameters["Id"].IsNullable = true;
command.Parameters["Stamp"].IsNullable = true;Executing the command:
updateCommand.Parameters["Id"].Value = item.Id;
updateCommand.Parameters["Stamp"].Value = item.TimeStamp;
updateCommand.ExecuteNonQuery(); Note that certain irrelevant bits have been cut out.
Sig cops got me...

|
|
|
|
Could you do a check on item.Id and if it is null replace the value sent as the parameter to DBNull.Value?
|
|
|
|
|
I think I tried that, but it was before I noticed a couple of other mistakes so when I get the chance in a couple of hours I shall do that.
Sig cops got me...

Yes that's cured it, thanks.

If i'm not wrong the SqlParameters are prefixed with @ symbol, and the above lines should be like this:
command.Parameters.Add("@Id", SqlDbType.Int);
command.Parameters.Add("@Stamp", SqlDbType.Timestamp);
command.Parameters["@Id"].IsNullable = true;
command.Parameters["@Stamp"].IsNullable = true;
