kyle@actarg.com<p>Try : <p>select sum(a.price + b.price) from items as a, widgets as b; <p>-Tony Reina</blockquote> I
explainedmy problem badly. <p>Here's the full thing. I'm doing this, which works: <p><tt>select -sum(tquant) from
mtr_regwhere</tt><br /><tt> status = 'clsd' and</tt><br /><tt> fr_proj = 20 and</tt><br /><tt> pnum =
'1122'</tt><br/><tt>union</tt><br /><tt>select sum(tquant) from mtr_reg where</tt><br /><tt> status = 'clsd'
and</tt><br/><tt> to_proj = 20 and</tt><br /><tt> pnum = '1122'</tt><br /><tt>;</tt><br />This yields two
numbers,one negative and the other positive. If I add them together <br />in the application, I get the number I
reallywant which represents the total number of <br />part 1122 that have come into inventory (project 20) minus the
totalnumber that have gone out <br />(i.e. current stock level). <p>What I'm trying to do is to have SQL do the
additionrather than having to read the <br />two sums separately and add them externally. <p>I think the example you
gaveadds up all the prices of all the combinations of pairs from <br />aliases a and b (billions and billions...). <br
