What I'm trying to do is get the last entry (by date) for a given entity (which should be a single row). The following returned more than one row:
select termId, entityId, max(enddate)
from Terms
where entityId = 1234
group by termId, entityId
This does return me one row:
select *
from Terms
where enddate in (select max(enddate)
from Terms
where entityId = 1234)
What I would like to do this in one select statement. Does anyone have any suggestions?

In the context of LATEX, some Pythonista asked what the big
successes of Lisp were. I think there were at least three *big*
successes.
a. orbitz.com web site uses Lisp for algorithms, etc.
b. Yahoo store was originally written in Lisp.
c. Emacs
The issues with these will probably come up, so I might as well
mention them myself (which will also make this a more balanced

I have a stored procedure that has some problems with slow performance.
The procedure has 2 parameters
@firstname varchar(100)

These parameters can have values like a%, that is wildcard searches.
The strange thing is that if one of the parameters has the value %, and
the other one a%, the performance is very bad.

Hi All,
Kind of new to this. What I have below works, but I am wondering if
there is a way to make it more efficient/simpler instead of having to
write an if, tr, td, blah for each datatype. How would I simplify this?
Any thoughts are appreciated.
Thanks,
Patrick

I'm having a hard time figuring out how to simplify the fractions. Can anyone look at this code and see if you can see something I don't.
//This is the fraction adding function
void add_fractions (int a, int b, int c, int d, int *ansn, int *ansd)
{
//int e, x, y, rem, gcd;
a = a*d; //numerator 1 * denominator 2
c = c*b; //numerator 2 * denominator 1
b = b*d; // denominator 1 * denominator 2
d = b; //denominator 2 = denominator 1

I've got the following XSLT that works but I'm trying to figure out how to

Anyone?

For most users, this new feature is actually very convenient. If you want to control the update process,...
