1.数据结构如下:

  vehicleId    mileage_type    mileage

  11AM6897             0        120

  11AM6897             1        60

  13AY9180      0        100

  31D07216      1        80

2.想得到一下结果:

  vehicleId    excutionMileage    nonExcutionMileage

  11AM6897             120            60

  13AY9180      100            0

  31D07216      0             80

3.sql:

SELECT
vehicle_id,IF (mileage_type = 1, mileage, 0) AS nonExcutionMileage,IF (mileage_type = 0, mileage, 0) AS excutionMileage
FROM
gps_basis.having_opened_vehicle_mileage_detail
SELECT vehicle_id,date,
case mileage_type when 0 then mileage else 0 end excutionMileage,
case mileage_type when 1 then mileage else 0 end nonExcutionMileage
FROM gps_basis.having_opened_vehicle_mileage_detail
