-- 修复脚本：将已经处于pending_receiving_approval状态的一级需求部门任务的第一个部门子任务状态更新为pending_approval
-- 执行时间：2026-01-22
-- 说明：修复一级需求部门任务在接单部门审核时子任务状态不正确的问题

-- 1. 查找需要修复的任务
-- 查询条件：approval_status='pending_receiving_approval' AND is_primary_task=1 AND is_pipeline=1
SELECT 
    t.id AS task_id,
    t.task_no,
    t.title,
    COUNT(ti.id) AS pending_subtask_count
FROM task t

  AND t.is_primary_task = 1 
  AND t.is_pipeline = 1 
  AND t.deleted = 0
GROUP BY t.id, t.task_no, t.title;

-- 2. 更新第一个部门的子任务状态为pending_approval
-- 更新条件：status='pending' AND is_locked=0（这些是第一个部门的子任务）
