-- OneOS 车辆品牌一次性只读校准
|
||||
--
|
||||
-- 边界：
|
||||
-- 1. 只读取 ln_asset_management.vehicle_info / vehicle_model。
|
||||
-- 2. 只更新中台 vehicle_identity_binding.oem 的空值，不覆盖已有品牌。
|
||||
-- 3. 每辆车在 vehicle_identity_oem_audit 留存来源编码、车型、版本和操作人。
|
||||
-- 4. 必须先应用 deploy/migrations/018_vehicle_oem_audit.sql。
|
||||
-- 5. 不得把本脚本改为定时跨库同步；后续持续同步应走 OneOS 正式 API。
