Two things - 1) Off the top of my head I would guess that the "@" symbols refer to something that is mysql specific (or in my limited postgresql experience, I have not seen/used it), 2) you should include an error message, cause that will tell you what type of error and approximate location, 3) to get help on this it may help other people if you formatted your query in a way that was more legible. For example:
select bs.toll_zone, bs.toll_fee,concat(r.route_number,if(r.route_direction='UP','UP','DN')) route_number,route_order, r.route_id,ifnull(bs.bus_stop_code, bs.bus_stop_id) bus_stop_code,ifnull(bs.bus_stop_name, '') bus_stop_name,(ifnull(bs.bus_stop_name_nudi, '')) bus_stop_name_nudi,bs.bus_stop_id, ifnull(bs.alias1, '') alias1,IF( if(ifnull(rm.schedule_distance, 0)='0',ifnull(rm.distance, 0),ifnull(rm.schedule_distance, 0)) IS NULL, @tot_dur := @tot_dur, @tot_dur := @tot_dur + if(ifnull(rm.schedule_distance, 0)='0',ifnull(rm.distance, 0),ifnull(rm.schedule_distance, 0)) )/1000 AS tot_dist, ifnull(rp.sub_stage,'N') sub_stage, ifnull(rp.fare_stage,'N') fare_stage,a.stage_count, rmd.adult, rmd.children, rmd.senior_citizenfrom route r JOIN (SELECT @tot_dur := 0) d inner join route_point rp on rp.route_id = r.route_id inner join bus_stop bs on bs.bus_stop_id=rp.bus_stop_id and bs.point_type_id!=2 left join route_map rm on rm.start_bus_stop_id=rp.bus_stop_id and rp.route_id='3004' and rm.route_id='3004' INNER JOIN (select route_id, route_points_id, if(if(rp.fare_stage='Y',1,0) IS NULL,@stage_count := @stage_count,@stage_count := @stage_count+if(rp.fare_stage='Y',1,0)) as stage_count from route_point rp JOIN (SELECT @stage_count := 0) e where rp.route_id='3004' ) aON rp.route_points_id = a.route_points_id INNER JOIN rate_master_details rmd ON a.stage_count = rmd.stage_no AND rmd.rate_master_id='12'where r.route_id='3004' AND bs.point_type_id NOT IN ('2', '13') order by r.route_id;

Subject: select query of mysql to postgres
I Have below query of mysql which is not executing in postgresql , What changes need to do to execute in postgressql database
select bs.toll_zone, bs.toll_fee, concat(r.route_number,if(r.route_direction='UP','UP','DN')) route_number, route_order, r.route_id, ifnull(bs.bus_stop_code, bs.bus_stop_id) bus_stop_code, ifnull(bs.bus_stop_name, '') bus_stop_name, (ifnull(bs.bus_stop_name_nudi, '')) bus_stop_name_nudi, bs.bus_stop_id, ifnull(bs.alias1, '') alias1, IF( if(ifnull(rm.schedule_distance, 0)='0',ifnull(rm.distance, 0),ifnull(rm.schedule_distance, 0)) IS NULL, @tot_dur := @tot_dur, @tot_dur := @tot_dur + if(ifnull(rm.schedule_distance, 0)='0',ifnull(rm.distance, 0),ifnull(rm.schedule_distance, 0)) )/1000 AS tot_dist, ifnull(rp.sub_stage,'N') sub_stage, ifnull(rp.fare_stage,'N') fare_stage,a.stage_count, rmd.adult, rmd.children, rmd.senior_citizenfrom route r JOIN (SELECT @tot_dur := 0) d inner join route_point rp on rp.route_id = r.route_id inner join bus_stop bs on bs.bus_stop_id=rp.bus_stop_id and bs.point_type_id!=2 left join route_map rm on rm.start_bus_stop_id=rp.bus_stop_id and rp.route_id='3004' and rm.route_id='3004' INNER JOIN (select route_id, route_points_id, if(if(rp.fare_stage='Y',1,0) IS NULL,@stage_count := @stage_count,@stage_count := @stage_count+if(rp.fare_stage='Y',1,0)) as stage_count from route_point rp JOIN (SELECT @stage_count := 0) e where rp.route_id='3004' ) aON rp.route_points_id = a.route_points_id INNER JOIN rate_master_details rmd ON a.stage_count = rmd.stage_no AND rmd.rate_master_id='12'where r.route_id='3004' AND bs.point_type_id NOT IN ('2', '13') order by r.route_id;
Below is the error while executing the query.
