何小存

关于，JEECG框架的联合主键，如下表结构，如何实现？
CREATE TABLE [dbo].[item_price_list](
        [item_cdoe] [varchar](20) NOT NULL,
        [item_space] [varchar](20) NOT NULL,
        [item_units] [varchar](20) NOT NULL,
        [item_class] [varchar](20) NOT NULL,
        [item_name] [nchar](10) NULL,
        [item_price] [nchar](10) NULL,
CONSTRAINT [PK_T[item_price_list]] PRIMARY KEY CLUSTERED
(
        [item_cdoe] ASC,
        [item_space] ASC,
        [item_units] ASC,
        [item_class] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]
