12,326,833 | I am sorry for posting a pretty redundant question. I was wondering if it was really necessary to use `else {}` if the code just stops or returns a value. In theory, is it really necessary to put `else{}` in these scenarios?

It's also a very common pattern to use, and IMHO, makes code more readable.
For the sake of code clarity/clean coding, if you're returning a boolean you should return a boolean even if the if() doesn't match.

You are dealing with so many layers there (Response.Write for the client, the ASP for the server, and the database) that its not surprising that there are problems.
Perhaps you can post some details about the error? | Based on the sugestions I will atempt to move the query into a CTE (common table expression) when I find a good tutorial on how to do that. For now and as a quick and dirty fix, I have changed the code as follows:

] | Yes it does. Here is another way
```
>>> sum(map( operator.mul, vector1, vector2))
48
```
and another that doesn't use `operator` at all
```
>>> vector1 = (2,3,5)
>>> vector2 = (3,4,6)
>>> sum(p*q for p,q in zip(vector1, vector2))
48
``` | You can also use the numpy implementation of [dot product](http://docs.scipy.org/doc/numpy/reference/generated/numpy.dot.html) which has large array optimizations in native code to make computations slightly faster. Even better unless you are specifically trying to write a dot product routine or avoid dependencies, usi... |
