生成数据库：

CREATE TABLE [dbo].[test01] (

[id] [decimal](18, 0) IDENTITY (1, 1) NOT NULL ,

[name] [varchar] (50) COLLATE Chinese_PRC_CI_AS NULL ,

[card] [varchar] (50) COLLATE Chinese_PRC_CI_AS NULL ,

[price] [decimal](18,2) NULL,

[createdate] [datetime] NULL

) ON [PRIMARY]

GO

ALTER TABLE [dbo].[test01] ADD

CONSTRAINT [DF_test01_createdate] DEFAULT (getdate()) FOR [createdate],

CONSTRAINT [PK_test01] PRIMARY KEY CLUSTERED

(

[id]

) ON [PRIMARY]

GO
