定义基本表

8个基本表建表sql如下：

CREATE TABLE Region(/*地区表*/regionkey INTEGER PRIMARY KEY ,name CHAR(25),COMMENT VARCHAR(152)
);CREATE TABLE Nation (/*国家表*/nationkey integer PRIMARY KEY ,name char(25),regionkey integer REFERENCES Region(regionkey),COMMENT varchar(152)
);CREATE TABLE supplier(/*供应商基本表*/suppkey integer PRIMARY KEY ,name char(25),address varchar(40),nationkey integer REFERENCES nation(nationkey),phone char(15),acctbal REAL ,COMMENT varchar(101)
);CREATE TABLE part(/*零件基本表*/partkey integer PRIMARY KEY ,name varchar(55),mfgr char(250),/* 书中为char(10) 字段长度不够，会导致导入报错，因此改为cahr(100) */brand char(100),"type" varchar(25),"size" integer ,container char(10),retailprice REAL ,COMMENT varchar(23)
);CREATE TABLE partsupp(/*零件供应联系表*/partkey integer REFERENCES part(partkey),suppkey integer REFERENCES supplier(suppkey),availqty integer ,supplycost REAL,COMMENT varchar(199),PRIMARY KEY(partkey,suppkey)
)CREATE TABLE customer(/*顾客表*/custkey integer PRIMARY KEY ,name varchar(25),address varchar(40),"nationkey" integer REFERENCES nation(nationkey),phone char(15),acctbal REAL,mktsegment char(10),COMMENT varchar(117)
);CREATE TABLE orders(/*订单表*/orderkey integer PRIMARY KEY ,custkey integer REFERENCES customer(custkey),orderdate date,orderstatus char(1),totalprice REAL,orderpriority char(15),clerk char(15),shippriority integer ,COMMENT varchar(79)
);CREATE TABLE lineitem(/*订单明细表*/orderkey integer REFERENCES orders(orderkey),partkey integer REFERENCES part(partkey),suppkey integer REFERENCES supplier(suppkey),linenumber integer ,quantity REAL,extendedprice REAL,discount REAL,tax REAL,returnflag char(1),linestatus char(1),shipdate date,commitdate date,receipdate date,shipinstruct char(25),shipmode char(10),COMMENT varchar(44),PRIMARY KEY (orderkey,linenumber),FOREIGN KEY (partkey,suppkey) REFERENCES partsupp(partkey,suppkey)
);
