strange update problem .net

Hi guys -

I have written a form, and a stored procedure to update the said form.
It really is as simple as that. A user can go into the form, update some fields and hit the update button to update the information which is stored in a SQL database.

In testing we noticed that the form was updating correctly but the update mechanism was also updating the first record of the table in the sql database every time. No error messages are on screen - it looks like everything has happened correctly until you go into the table manually and realise it has updated the first record of the table with exacly the same info as the correct record.

We have tried a number of things here to stop it updating the first record, but can't manage it. It's like the update completely ignores the unique identifier and decides it's going to update the first record in the table also.

Has anyone had trouble like this before?
This is a fairly important application, so if anyone could shed some light on it that would be great.

I have included as much code as I can below - there is an awful lot of it.
If there are any questions you have you need clarified I'd be happy to do that.

Many thanks in advance.
DS

re: strange update problem .net

In the future it might be a good idea just to post the code that you think is causing the problem instead of everything. It's hard to read through a lot of code to just to find the function(s) that you are having problems....It makes it especially hard to understand when you have buttons named like "Submit" and "LinkButton1"...I'm not sure what these buttons are supposed to actually be doing.

Anyways, your Submit button seems to have code for handling your table update...however your page load event also seems to be doing something with your table. One of these methods could be updating the wrong thing.

re: strange update problem .net

Avoiding for now that your page_load() looks like it is doing something fishy and is likely the culprit...

I don't see your actual update procedure, just an sql function that could select multiple results, but you only return one.


In my StoredProcedures that do updates, I frequently will include a count() to determine the number of records effected.
For isntance a snippit might be:
Expand|Select|Wrap|Line Numbers
  1. SELECT
  2.    @RowsAffected=count(*)
  3. FROM
  4.    [Assemblies]
  5. WHERE 
  6.    [AssemblyID] = @AssemblyID; 
  7.  
  8. --do update
  9. UPDATE 
  10.    [Assemblies]
  11. SET 
  12.    [LaborHours] = @LaborHours
  13.    ,[Notes] = @Notes
  14.    ,[ModifiedDate] = @ModifiedDate
  15. WHERE 
  16.    [AssemblyID] = @AssemblyID;
  17.  
  18. RETURN @RowsAffected;
