+# 插入已认证公司测试数据
+
+## SQL插入语句
+
+请在数据库中执行以下SQL语句，插入测试用的已认证公司数据：
+
+```sql
+-- 插入已认证公司测试数据
+INSERT INTO silver_companies (
+  name, short_name, industry_category, company_type, employee_count,
+  address, longitude, latitude, contact_person, contact_phone,
+  is_certified, user_id, view_count, favorite_count
+) VALUES
+  ('北京银龄科技有限公司', '银龄科技', '科技服务', '民营企业', '50-100人',
+   '北京市朝阳区科技园区88号A座', 116.4074, 39.9042, '张经理', '13888888888',
+   1, 1001, 156, 23),
+  ('上海智慧养老服务有限公司', '智慧养老', '养老服务', '有限公司', '100-500人',
+   '上海市浦东新区张江高科技园区999号', 121.4737, 31.2304, '李总监', '13999999999',
+   1, 1002, 89, 12),
+  ('广州乐龄人力资源有限公司', '乐龄人力', '人力资源', '股份有限公司', '200-1000人',
+   '广州市天河区珠江新城888号', 113.2644, 23.1291, '王主管', '13777777777',
+   1, 1003, 234, 45),
+  ('深圳颐养天年健康管理有限公司', '颐养天年', '健康管理', '有限公司', '50-200人',
+   '深圳市南山区科技园777号', 113.9448, 22.5431, '刘经理', '13666666666',
+   1, 1004, 167, 34),
+  ('成都银发经济发展有限公司', '银发经济', '经济发展', '民营企业', '100-500人',
+   '成都市高新区天府软件园666号', 104.0668, 30.5728, '陈总监', '13555555555',
+   1, 1005, 98, 18);
+
+-- 验证插入的数据
+SELECT id, name, is_certified, created_at FROM silver_companies WHERE is_certified = 1;
+```
+
+## 测试验证
+
+### 1. 直接API测试
+访问以下URL测试认证公司API：
+```
+https://your-domain.com/api/v1/silver-companies/certified?page=1&pageSize=100
+```
+
+### 2. 使用curl测试
+```bash
+curl -X GET 'https://d8d-ai-vscode-8080-152-136-template-9-group.r.d8d.fun/api/v1/silver-companies/certified?page=1&pageSize=100'
+```
+
+### 3. 前端验证
+1. 打开银龄岗管理页面
+2. 点击"新建岗位"按钮
+3. 在公司名称下拉框中应该看到上述5家已认证公司
+4. 可以搜索如"银龄"、"科技"等关键词进行筛选
+
+## 预期结果
+
+执行上述插入语句后，在前端将看到：
+- 北京银龄科技有限公司
+- 上海智慧养老服务有限公司
+- 广州乐龄人力资源有限公司
+- 深圳颐养天年健康管理有限公司
+- 成都银发经济发展有限公司
+
+这些公司已通过认证（is_certified=1），可以在新建岗位时直接选择使用。
