+-- 修复项目申报中申请人ID为空的问题
+-- 创建时间: 2025-08-01
+-- 描述: 检查并修复cw_project_application表中applicant_id为NULL的记录
+-- ==========================================
+
+-- 1. 检查问题记录
+SELECT 
+    id,
+    application_no,
+    project_name,
+    applicant_id,
+    applicant_name,
+    department_id,
+    department_name,
+    approval_status,
+    create_by,
+    create_time
+FROM cw_project_application 
+WHERE applicant_id IS NULL OR applicant_id = 0;
+
+-- 2. 修复方案1：将申请人ID设置为创建者ID（推荐）
+UPDATE cw_project_application 
+SET 
+    applicant_id = create_by,
+    applicant_name = (
+        SELECT nick_name 
+        FROM sys_user 
+        WHERE user_id = cw_project_application.create_by 
+        AND deleted = 0
+        LIMIT 1
+    )
+WHERE (applicant_id IS NULL OR applicant_id = 0) 
+  AND create_by IS NOT NULL
+  AND create_by > 0;
+
+-- 3. 修复方案2：如果创建者也为空，设置为系统管理员（ID=1）
+UPDATE cw_project_application 
+SET 
+    applicant_id = 1,
+    applicant_name = '系统管理员'
+WHERE (applicant_id IS NULL OR applicant_id = 0) 
+  AND (create_by IS NULL OR create_by = 0);
+
+-- 4. 修复部门信息为空的记录

+        SELECT dept_id 
+        FROM sys_user 
+        WHERE user_id = cw_project_application.applicant_id 
+        AND deleted = 0
+        LIMIT 1
+    ),

+        SELECT d.dept_name 
+        FROM sys_user u 
+        LEFT JOIN sys_dept d ON u.dept_id = d.dept_id

+  AND applicant_id IS NOT NULL 
+  AND applicant_id > 0;
+
+-- 5. 验证修复结果
+SELECT 
+    '修复后检查' as check_type,
