and score table is

personid      score 1             50 2             100 3             75 4             50 4             75

i query returned like

category    totalscore    names 1           150           dave, john 2           200           lisa, jim

is possible 1 query?

i can totals sum query , grouping category cannot see way names like.

many thanks

you need use group_concat:

select category, sum(score) totalscore, group_concat(name) names categories join scores on scores.category = categories.category group category

or better:

group_concat(distinct name order name asc separator ',') names

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
