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]
