+-- 深度调试：找出导致Data truncation的具体数据
+-- ====================================
+
+-- 1. 检查xq_client_log表的latitude字段定义
+SELECT 
+    COLUMN_NAME,
+    DATA_TYPE,
+    CHARACTER_MAXIMUM_LENGTH,
+    COLUMN_TYPE
+FROM INFORMATION_SCHEMA.COLUMNS 
+WHERE TABLE_SCHEMA = DATABASE() 
+AND TABLE_NAME = 'xq_client_log'
+AND COLUMN_NAME = 'latitude';
+
+-- 2. 检查iot_device_data表中项圈设备的所有字段长度
+SELECT 
+    device_id,
+    voltage,
+    temperature,
+    latitude,
+    longitude,
+    steps,
+    same_day_steps,
+    server_device_id,
+    LENGTH(CAST(voltage AS CHAR)) as voltage_len,
+    LENGTH(CAST(temperature AS CHAR)) as temp_len,
+    LENGTH(latitude) as lat_len,
+    LENGTH(longitude) as lng_len,

+    LENGTH(server_device_id) as server_id_len,
+    HEX(latitude) as lat_hex,
+    HEX(longitude) as lng_hex
+FROM iot_device_data 
+WHERE device_type = 4 
+ORDER BY LENGTH(latitude) DESC
+LIMIT 10;
+
+-- 3. 检查是否有任何字段长度超过200
+SELECT 
+    device_id,
+    CASE 
+        WHEN LENGTH(CAST(voltage AS CHAR)) > 200 THEN CONCAT('voltage:', LENGTH(CAST(voltage AS CHAR)))
+        WHEN LENGTH(CAST(temperature AS CHAR)) > 200 THEN CONCAT('temperature:', LENGTH(CAST(temperature AS CHAR)))

+        WHEN LENGTH(longitude) > 200 THEN CONCAT('longitude:', LENGTH(longitude))
+        WHEN LENGTH(server_device_id) > 200 THEN CONCAT('server_device_id:', LENGTH(server_device_id))
+        ELSE 'OK'
+    END as field_issue,
+    voltage,
+    temperature,
+    latitude,
+    longitude,
+    server_device_id
+FROM iot_device_data 
+WHERE device_type = 4 
+AND (

+    LENGTH(latitude) > 200 OR
+    LENGTH(longitude) > 200 OR
+    LENGTH(server_device_id) > 200
+);
+
+-- 4. 尝试插入第9条数据（错误信息提到row 9）
+SELECT 
+    device_id,
+    voltage,
+    temperature,
+    latitude,
+    longitude,
+    steps,
+    same_day_steps,
+    server_device_id,
+    ROW_NUMBER() OVER (ORDER BY update_time DESC) as row_num
+FROM iot_device_data 
+WHERE device_type = 4 
+ORDER BY update_time DESC
+LIMIT 10;
+
+-- 5. 检查第9条数据的具体内容
+WITH ranked_data AS (
+    SELECT 
+        device_id,
+        voltage,
+        temperature,
+        latitude,

+        steps,
+        same_day_steps,

+        ROW_NUMBER() OVER (ORDER BY update_time DESC) as row_num
+    FROM iot_device_data 
+    WHERE device_type = 4 
+    ORDER BY update_time DESC
+)
+SELECT 
+    device_id,
+    voltage,
+    temperature,
+    latitude,
+    longitude,

+    LENGTH(latitude) as lat_len,
+    LENGTH(longitude) as lng_len,
+    HEX(latitude) as lat_hex,
