I'm not sure I understand exactly what your asking for, but it sounds similar to something I have done in the past.I run a query and get back a featureSet, in each feature that returns there is an attribute object in my case there was a particular variable in that attribute object called entityType. Depending on the entityType I displayed a different symbol on the map.for example if the feature had an entityType of "Person" I displayed a red teardrop, if the feature had an entityType of "Organization" I displayed a green teardrop, for "Vehicle" it was yellow, etc, etc...I handled this by setting up what I called a symbolBank, which was a javascript object that worked pretty much like a java HashMap; the code looks like this...
symbolBank = {
"Person": new esri.symbol.PictureMarkerSymbol('/images/red_teardrop.png', 25, 25),
"Organization": new esri.symbol.PictureMarkerSymbol('/images/green_teardrop.png', 25, 25),
"Vehicle": new esri.symbol.PictureMarkerSymbol('/images/yellow_teardrop.png', 25, 25)
}
Access the object by looping through the featureSet and keying off of the attribute you need to create the symbol. In my case it looks like this...
dojo.forEach(featureSet, function(feature){
var symbol = symbolBank[feature.attributes.entityType];
var graphic = new esri.Graphic(feature.geometry, symbol);
map.graphics.add(graphic);
});
