В MySQL това може да се постигне, както следва
SELECT id, length FROM vehicles WHERE id IN ( 117, 148, 126)
+---------------+
| id | length |
+---------------+
| 117 | 25 |
| 126 | 8 |
| 148 | 10 |
+---------------+
SELECT id,vehicle_ids FROM load_plan_configs WHERE load_plan_configs.id =42
+---------------------+
| id | vehicle_ids |
+---------------------+
| 42 | 117, 148, 126 |
+---------------------+
Сега, за да получите дължината на разделените със запетая vehicle_ids, използвайте по-долу заявка
Output
SELECT length
FROM vehicles, load_plan_configs
WHERE load_plan_configs.id = 42 AND FIND_IN_SET(
vehicles.id, load_plan_configs.vehicle_ids
)
+---------+
| length |
+---------+
| 25 |
| 8 |
| 10 |
+---------+
