Var means "infer the type of the variable at compile-time" - but it's still entirely statically bound .
No, they're very different.

I have a C# 4.0 parser. It accepts 'dynamic' as a keyword as a type. My parser trips over statements found in working C# 3.0 programs of the form of:

What does the SQL Action keyword do? Can I use this keyword in a trigger and determine if the trigger was called by an Insert, Delete or Update?

Answer Snippets (Read the full thread at stackoverflow):
A vary basic example would go something like this:
If exists (select * from inserted) and exists (select * from deleted) --Update happened If exists... .
But you can look at the Inserted and Deleted tables to see what happened .
No, you can't use it for that.
