sql server data mining : Substring'ing a Number-field

Hi :) and thanx for reading my post.

I have to create a view based on a character in a number-field (fnr)
which is 11 char's long. I have to get character nr "7".

The problem is that i cannot use :

--> SELECT fnr FROM table WHERE substring(fnr,7,1)
since it's not a string.

Any other way i can solve this ? Would be greatly and insanely happy if
anyone could help me out with a sample code or something.!

Best regards
Mirador

SELECT fnr FROM table WHERE SUBSTRING(CONVERT(VARCHAR, fnr), 7, 1) ...

Note that performance is really going to be horrible with this method...
Since you appear to be using the column as a bitmask (or is it integer mask)
of sorts, I recommend you seriously consider splitting it into multiple
columns.
