-- crm_channel_expansion.channel_code data fix:
|
||
|
|
-- normalize all existing channel codes to the current system rule
|
||
|
|
--
|
||
|
|
-- Rule:
|
||
|
|
-- QD-YYYYMMDD-序号(按记录创建日期、创建时间、ID排序生成)
|
||
|
|
--
|
||
|
|
-- Notes:
|
||
|
|
-- 1) all rows are recalculated using current rule
|
||
|
|
-- 2) rows are ordered by created_at asc, id asc within each day
|
||
|
|
-- 3) script is idempotent: rerun yields the same result
