-- 🚀 智能修复 user_package 表 - 2026-01-23
|
|
-- 根据实际情况添加缺失的字段
|
|
|
|
-- 1. 先检查表结构
|
|
SELECT '=== 当前表结构 ===' AS '';
|
|
DESC user_package;
|
|
|
|
-- 2. 尝试添加 update_time 字段（如果不存在）
|
|
SET @sql = 'ALTER TABLE user_package ADD COLUMN `update_time` DATETIME DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT ''更新时间''';
|
|
|
|
-- 检查字段是否存在
|
|
SET @column_exists = (
|
|
SELECT COUNT(*)
|
|
FROM INFORMATION_SCHEMA.COLUMNS
|
|
WHERE TABLE_SCHEMA = 'peixue'
|
|
AND TABLE_NAME = 'user_package'
|
|
AND COLUMN_NAME = 'update_time'
|
|
);
|
|
|
|
-- 如果字段不存在，则执行添加
|
|
SET @sql = IF(@column_exists = 0, @sql, 'SELECT ''update_time 字段已存在'' AS message');
|
|
PREPARE stmt FROM @sql;
|
|
EXECUTE stmt;
|
|
DEALLOCATE PREPARE stmt;
|
|
|
|
-- 3. 检查 create_time 字段的默认值
|
|
SELECT
|
|
COLUMN_NAME AS '字段名',
|
|
COLUMN_TYPE AS '字段类型',
|
|
COLUMN_DEFAULT AS '默认值',
|
|
EXTRA AS '额外属性'
|
|
FROM INFORMATION_SCHEMA.COLUMNS
|
|
WHERE TABLE_SCHEMA = 'peixue'
|
|
AND TABLE_NAME = 'user_package'
|
|
AND COLUMN_NAME IN ('create_time', 'update_time', 'created_time', 'updated_time');
|
|
|
|
-- 4. 如果 create_time 存在但没有默认值，修改它
|
|
SET @fix_create_time = (
|
|
SELECT COUNT(*)
|
|
FROM INFORMATION_SCHEMA.COLUMNS
|
|
WHERE TABLE_SCHEMA = 'peixue'
|
|
AND TABLE_NAME = 'user_package'
|
|
AND COLUMN_NAME = 'create_time'
|
|
AND COLUMN_DEFAULT IS NULL
|
|
);
|
|
|
|
SET @sql = IF(@fix_create_time > 0,
|
|
'ALTER TABLE user_package MODIFY COLUMN `create_time` DATETIME DEFAULT CURRENT_TIMESTAMP COMMENT ''创建时间''',
|
|
'SELECT ''create_time 字段配置正确'' AS message'
|
|
);
|
|
PREPARE stmt FROM @sql;
|
|
EXECUTE stmt;
|
|
DEALLOCATE PREPARE stmt;
|
|
|
|
-- 5. 验证修复结果
|
|
SELECT '=== 修复后的表结构 ===' AS '';
|
|
DESC user_package;
|
|
|
|
SELECT '✅ user_package 表已修复' AS '状态';
|
