建表语句：

CREATE TABLE [dbo].[Table_test](
 [A] [int] NOT NULL,
 [B] [varchar](40) NOT NULL,
 [C] [int] NOT NULL,
 [D] [varchar](20) NULL,
 [E] [varchar](50) NULL,
 CONSTRAINT [PK_Table_test] PRIMARY KEY CLUSTERED
(
 [A] ASC,
 [B] ASC,
 [C] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]
