-- Migration: refund commission for existing pending (status=0) withdrawals
|
|
--
|
|
-- Under the old logic, commission was deducted when a withdrawal was submitted.
|
|
-- Under the new logic, commission is only deducted on approval.
|
|
-- This migration refunds the deducted amounts back to each user so that
|
|
-- the system is in a consistent state before the new code is deployed.
|
|
--
|
|
-- Idempotency: the UPDATE only touches rows whose commission would need
|
|
-- to increase, and each execution produces the same result because
|
|
-- COALESCE(SUM(amount),0) is deterministic given the same pending set.
|
|
-- Running this script multiple times is safe only if no new pending
|
|
-- withdrawals are created between runs; deploy new code immediately after.
|
|
|
|
-- Step 1: refund commission for all users with pending withdrawals.
