-- 1. users 表迁移
|

-- ============================================================
|
||
-- 源表: MySQL user (2,202 条记录)
|
||
-- 目标表: SQL Server users
|
||
-- 字段映射: openid->open_id, headimg->head_img, istest->is_test
|
||
-- 时间戳转换: DATEADD(SECOND, unix_timestamp, '1970-01-01')
|
||
-- 状态: 已完成 (72条样本数据已验证)

-- 2. user_accounts 表迁移
|
||
-- ============================================================
|
||
-- 源表: MySQL user_account (3,452 条记录)
|
||
-- 目标表: SQL Server user_accounts
|
||
-- 字段映射: 字段名保持一致
|
||
-- 时间戳转换: token_time, last_login_time (Unix时间戳 → DATETIME2)
|
||
-- 状态: 进行中
|
||
|
||
-- 迁移方法说明：
|
||
-- 1. 启用 IDENTITY_INSERT: SET IDENTITY_INSERT user_accounts ON;
|
||
-- 2. 批量插入数据，每批50-100条
|
||
-- 3. 时间戳转换: DATEADD(SECOND, unix_timestamp, '1970-01-01')
|
||
-- 4. 完成后关闭: SET IDENTITY_INSERT user_accounts OFF;
|
||
|
||
-- 示例插入语句:
|
||
-- INSERT INTO user_accounts (id, user_id, account_token, token_num, token_time, last_login_time, last_login_ip, last_login_ip1, ip_adcode, ip_province, ip_city) VALUES
