-- 紧急修复xq_client_log表字段长度问题
|
||
-- 解决Data truncation错误，确保数据能正常插入
|
||
|
||
-- 1. 检查当前字段长度
|
||
SELECT
|
||
COLUMN_NAME,
|
||
DATA_TYPE,
|
||
CHARACTER_MAXIMUM_LENGTH,
|
||
NUMERIC_PRECISION,
|
||
NUMERIC_SCALE
|
||
FROM INFORMATION_SCHEMA.COLUMNS
|
||
WHERE TABLE_SCHEMA = DATABASE()
|
||
AND TABLE_NAME = 'xq_client_log'
|
||
AND COLUMN_NAME IN ('latitude', 'longitude', 'device_voltage', 'device_temp', 'server_device_id');
|
||
|
||
-- 2. 修改所有字段长度为更大的值
|
||
ALTER TABLE xq_client_log MODIFY COLUMN latitude VARCHAR(500) DEFAULT NULL COMMENT '纬度';
|
||
ALTER TABLE xq_client_log MODIFY COLUMN longitude VARCHAR(500) DEFAULT NULL COMMENT '经度';
|
||
ALTER TABLE xq_client_log MODIFY COLUMN device_voltage VARCHAR(500) DEFAULT NULL COMMENT '设备电量';
|
||
ALTER TABLE xq_client_log MODIFY COLUMN device_temp VARCHAR(500) DEFAULT NULL COMMENT '设备温度';
|
||
ALTER TABLE xq_client_log MODIFY COLUMN server_device_id VARCHAR(500) DEFAULT NULL COMMENT '主机设备ID';
|
||
|
||
-- 3. 验证修改结果
|
||
SELECT
|
||
COLUMN_NAME,
|
||
DATA_TYPE,
|
||
CHARACTER_MAXIMUM_LENGTH
|
||
FROM INFORMATION_SCHEMA.COLUMNS
|
||
WHERE TABLE_SCHEMA = DATABASE()
|
||
AND TABLE_NAME = 'xq_client_log'
|
||
AND COLUMN_NAME IN ('latitude', 'longitude', 'device_voltage', 'device_temp', 'server_device_id');
|
||
|
||
-- 4. 清空表并准备重新同步
|
||
TRUNCATE TABLE xq_client_log;
|
||
|
||
-- 5. 检查表是否为空
|
||
SELECT COUNT(*) as record_count FROM xq_client_log;
