怎么将这两个值组合到一起

'insert into '+@ResultTable 
							+ ' select a.EXITSTATION,b.STATIONNAME,11,RTRIM('+@TollDate+')+''a.exitdate'',a.recordtype,	
							sum(sign(a.vehicleclass^1)^1) ,
							sum(sign(a.vehicleclass^2)^1) ,
							sum(sign(a.vehicleclass^3)^1) ,
							sum(sign(a.vehicleclass^4)^1) ,
							sum(sign(a.vehicleclass^11)^1) ,
							sum(sign(a.vehicleclass^12)^1) ,
							sum(sign(a.vehicleclass^13)^1) ,
							sum(sign(a.vehicleclass^14)^1) ,
							sum(sign(a.vehicleclass^15)^1) ,
						    0,0,0
							from '+@BaseTable+ ' AS A,BASE_STATION380 AS B'
                            +' where 1=1 '+case when @Record<>'' then ' and a.Recordtype&'+@Record+'='''+@Record+''' ' else '' end
                            +' and a.EXITSTATION = B.STATIONID'

                                                       WHEN '' THEN 'a.Exitstation' 
                                                       ELSE @Station 
                                                      END
