‘帐户当前被锁定,所以用户 'sa' 登录失败。系统管理员无法将该帐户解锁’解决方法
如果短时间内不停连接，就会被SQL SERVER误认为是这是攻击，会将此账号锁定。
要用windows身份验证登录，在查询分析器里输入：
ALTER LOGIN sa ENABLE ;
GO
ALTER LOGIN sa WITH PASSWORD = 'password' unlock, check_policy = off,
c
RESTORE DATABASE his
FROM DISK = 'E:\RDHL文件\HIS相关文档\数据库备份\biaozhun.bak'
with replace,
MOVE 'his' TO 'C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\DATA\his.mdf',
MOVE 'his_log' TO 'C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\DATA\his_log.
