Hello,
When running a stored procedure (from a .NET application) that does an INSERT and an UPDATE, I sometimes (but not that often, really) and randomly get this error:

Assuming that your tables are properly indexed (and that you are actually using those indexes - always worth checking via the query plan) you could try breaking the component parts of the SP down and wrapping them in separate transactions so that each... .

Is there a situation where the use of a list leads to an error, and you must use a tuple instead?

Because of their immutable nature, tuples (unlike lists) are hashable... .
D = {[1, 2]: 'a', [3, 8, 1]: 'b'} # Error .
Eg:
d = {(1, 2): 'a', (3, 8, 1): 'b'} # Valid .
You can use tuples as dictionary keys, because they are immutable, but you can't use lists .

Would having a working knowledge of a lower level language benefit me in the future?

I have a single view which has a menu on the left hand side and a container on the right hand side that is rendered from one of several partial views.
Right now I'm running into a situation like the following "Index" view:

You could either
a) (if you're using, or will be using, ASP.NET 4) add a call to Html.Action() or Html.RenderAction() instead, and let the controller action decide which partial to render .

There's a client server application. Client - .NET 2.0 based desktop application. Server - ASP .NET 2.0 based web application.
The client communicates with the server using normal HTTP requests, since the server is essentially a website hosted on a web...

I don't see them being useful in your case as long the app usage stays on the LAN .
Proxies on the LAN are only useful if you're going to be doing some kind of filtering or accounting .

Now one of the key things about OpenID is that

That is, database or distributed cache.
Save the conversation state in a shared storage.
The generic issue I fear is that the RP connects to the OP and ends up on a different application server than the user .

If the attributes should be (1, 2, 5), you'll have to change the count to 3 .
Key is the HAVING COUNT statement being equal to the amount of attributes that have to match .
The example is written for SQLServer but the query should work in mysql as wel .

The way you've done it, though, it's the default constructor that calls the paramaterized contructor, giving it a default parameter to work with .
Your example nearly does what you are asking for.
