我想获得以下结果：

GUID     ClientGUID      TASK                 VALUE

123     15757400200   Dollar Unit            Consult Time 15 Min (Quantity):1 ;  Patient/Family Education 15 min (Qty):1
456     15757400200   Swallow Clarification  Swallow therapy 30 min (Qty):1

Answer 1

也许这个脚本很有用：

queryset2 = ModelB.objects.all().filter(par3__in=queryset1.values_list('X', flat=True), par4="Z")

Answer 2

您可以使用STUFF获得所需的结果。

     STUFF( ( SELECT  ',' +  VALUE
                    FROM tablename  where "put your condition here"
                    FOR XML PATH ('')  ) , 1,1,'') AS value
