How do I optimize this?

Hi all.

I have the following scenario:

A table T (int t1; int t2; ... int t10; int tkey)
A table D (int da; int db),

And I have the following query
update T set t1 = b.aa FROM (select COUNT(1) as aa FROM D WHERE D.da = 
<count>) as b where tkey = <value>;
update T set t2 = b.aa FROM (select COUNT(1) as aa FROM D WHERE D.da = 
<count>) as b where tkey = <value>;
...
update T set t10 = b.aa FROM (select COUNT(1) as aa FROM D WHERE D.da = 
<count>) as b where tkey = <value>;

The queries are run on the same <value>. Is there anyway to optimize this???


Thanks
