Можете да използвате ntile :
SELECT car_id, "date", ntile(CASE WHEN c <=5 THEN 1 WHEN c <=10 THEN 2 ELSE 3 END) OVER (PARTITION BY car_id ORDER BY "date") AS group_idFROM (SELECT car_id , "date", COUNT(*) OVER(PARTITION BY car_id) AS c FROM Table1) AS s Изход:
<предварителен код>╔════════╦══════════╦══════════╗║ car_id ║ дата ║ group_id ␑═ ════╬══════════╬══════════╣║ 1 ║ 20160101 ║ 1 ║║ 1 ║ 20160103 ║ 1 ║║ 1 ║ 20160105 ║ 1 ║║ 1 ║ 20160106 ║ 1 ║║ 1 ║ 20160107 ║ 2 ║║ 1 ║ 20160108 ║ 2 ║║ 1 ║ 20160109 ║ 2 ║║ 1 ║ 20160110 ║ 2 ║║ 2 ║ 20160102 ║ 1 ║║ 2 ║ 20160104 ║ 1 ║╚══ ══════╩══════════╩══════════╝
