自增列：[PID] [int] IDENTITY (1,1) NOT NULL
设置主键：这里的PK_t_LockDatanet前缀PK_不好理解，呵呵。
ALTER TABLE hyoa_SysInfo..t_LockDatanet ADD CONSTRAINT
PK_t_LockDatanet PRIMARY KEY CLUSTERED
(
PID
) ON [PRIMARY];
设置默认值：DF_t_LockDatanet_TotalNum前缀DF_表名_字段名
ALTER TABLE hyoa_SysInfo..t_LockDatanet ADD
CONSTRAINT [DF_t_LockDatanet_TotalNum] DEFAULT (5) FOR [TotalNum],
CONSTRAINT [DF_t_LockDatanet_DataTime] DEFAULT (getdate()) FOR [DataTime]
