TPC-H tools的使用

1. 首先从TPC官网上下载TPC-H tools的压缩包，网址为：http://www.tpc.org/tpc_documents_current_versions/current_specifications.asp；

2. 解压；

3. 使用Visual Studio打开项目tpch.sln（dbgen目录下）；

4. 右键dbgen项目，选择生成，然后将dbgen\Debug目录下的dbgen.exe拷贝到dbgen目录下；

5. 此时，通过cmd到dbgen目录下，便可根据命令“dbgen-vf -s 1”生成测试数据库实例（-s后面的是Scale Facter因子）；

6. 后缀名为“.tbl”即为生成的数据。

7. 然后我在MySQL数据库上建立一个数据库，名为“tpch”；

8. 所有的建表语句在文件dss.ddl中，但是原始文件中没有主外键的约束，所以我自己添加了主外键的约束，注意LINEITEM与PARTSUPP之间存在混合引用的关系，具体建表语句如下：

DROP TABLE IF EXISTS LINEITEM;

DROP TABLE IF EXISTS ORDERS;

DROP TABLE IF EXISTS CUSTOMER;

DROP TABLE IF EXISTS PARTSUPP;

DROP TABLE IF EXISTS SUPPLIER;

DROP TABLE IF EXISTS PART;

DROP TABLE IF EXISTS NATION;

DROP TABLE IF EXISTS REGION;

CREATE TABLE REGION  ( R_REGIONKEY  INTEGER NOT NULL,
R_NAME       CHAR(25) NOT NULL,
R_COMMENT    VARCHAR(152),
PRIMARY KEY(R_REGIONKEY));

CREATE TABLE NATION  ( N_NATIONKEY  INTEGER NOT NULL,
N_NAME       CHAR(25) NOT NULL,
N_REGIONKEY  INTEGER NOT NULL,
N_COMMENT    VARCHAR(152),
PRIMARY KEY(N_NATIONKEY),
FOREIGN KEY(N_REGIONKEY) REFERENCES REGION(R_REGIONKEY));

CREATE TABLE PART  ( P_PARTKEY     INTEGER NOT NULL,
P_NAME        VARCHAR(55) NOT NULL,
P_MFGR        CHAR(25) NOT NULL,
P_BRAND       CHAR(10) NOT NULL,
P_TYPE        VARCHAR(25) NOT NULL,
P_SIZE        INTEGER NOT NULL,
P_CONTAINER   CHAR(10) NOT NULL,
P_RETAILPRICE DECIMAL(15,2) NOT NULL,
P_COMMENT     VARCHAR(23) NOT NULL,
PRIMARY KEY(P_PARTKEY));

CREATE TABLE SUPPLIER ( S_SUPPKEY     INTEGER NOT NULL,
S_NAME        CHAR(25) NOT NULL,
S_ADDRESS     VARCHAR(40) NOT NULL,
S_NATIONKEY   INTEGER NOT NULL,
S_PHONE       CHAR(15) NOT NULL,
S_ACCTBAL     DECIMAL(15,2) NOT NULL,
S_COMMENT     VARCHAR(101) NOT NULL,
PRIMARY KEY(S_SUPPKEY),
FOREIGN KEY(S_NATIONKEY) REFERENCES NATION(N_NATIONKEY));

CREATE TABLE PARTSUPP ( PS_PARTKEY     INTEGER NOT NULL,
PS_SUPPKEY     INTEGER NOT NULL,
PS_AVAILQTY    INTEGER NOT NULL,
PS_SUPPLYCOST  DECIMAL(15,2)  NOT NULL,
PS_COMMENT     VARCHAR(199) NOT NULL,
PRIMARY KEY(PS_PARTKEY, PS_SUPPKEY),
FOREIGN KEY(PS_PARTKEY) REFERENCES PART(P_PARTKEY),
FOREIGN KEY(PS_SUPPKEY) REFERENCES SUPPLIER(S_SUPPKEY));

CREATE TABLE CUSTOMER ( C_CUSTKEY     INTEGER NOT NULL,
C_NAME        VARCHAR(25) NOT NULL,
C_ADDRESS     VARCHAR(40) NOT NULL,
C_NATIONKEY   INTEGER NOT NULL,
C_PHONE       CHAR(15) NOT NULL,
C_ACCTBAL     DECIMAL(15,2)   NOT NULL,
C_MKTSEGMENT  CHAR(10) NOT NULL,
C_COMMENT     VARCHAR(117) NOT NULL,
PRIMARY KEY(C_CUSTKEY),
FOREIGN KEY(C_NATIONKEY) REFERENCES NATION(N_NATIONKEY));

CREATE TABLE ORDERS  ( O_ORDERKEY       INTEGER NOT NULL,
O_CUSTKEY        INTEGER NOT NULL,
O_ORDERSTATUS    CHAR(1) NOT NULL,
O_TOTALPRICE     DECIMAL(15,2) NOT NULL,
O_ORDERDATE      DATE NOT NULL,
O_ORDERPRIORITY  CHAR(15) NOT NULL,
O_CLERK          CHAR(15) NOT NULL,
O_SHIPPRIORITY   INTEGER NOT NULL,
O_COMMENT        VARCHAR(79) NOT NULL,
PRIMARY KEY(O_ORDERKEY),
FOREIGN KEY(O_CUSTKEY) REFERENCES CUSTOMER(C_CUSTKEY));

CREATE TABLE LINEITEM ( L_ORDERKEY    INTEGER NOT NULL,
L_PARTKEY     INTEGER NOT NULL,
L_SUPPKEY     INTEGER NOT NULL,
L_LINENUMBER  INTEGER NOT NULL,
L_QUANTITY    DECIMAL(15,2) NOT NULL,
L_EXTENDEDPRICE  DECIMAL(15,2) NOT NULL,
L_DISCOUNT    DECIMAL(15,2) NOT NULL,
L_TAX         DECIMAL(15,2) NOT NULL,
L_RETURNFLAG  CHAR(1) NOT NULL,
L_LINESTATUS  CHAR(1) NOT NULL,
L_SHIPDATE    DATE NOT NULL,
L_COMMITDATE  DATE NOT NULL,
L_RECEIPTDATE DATE NOT NULL,
L_SHIPINSTRUCT CHAR(25) NOT NULL,
L_SHIPMODE     CHAR(10) NOT NULL,
L_COMMENT      VARCHAR(44) NOT NULL,
PRIMARY KEY(L_ORDERKEY, L_LINENUMBER),
FOREIGN KEY(L_PARTKEY, L_SUPPKEY) REFERENCES PARTSUPP(PS_PARTKEY, PS_SUPPKEY));

9. 然后开始数据导入，具体导入命令如下（下述命令不能正常运行的话，则在登录MySQL客户端时加“--local-infile”）：

LOAD DATA LOCAL INFILE '~/tpchdata/region.tbl' INTO TABLE REGION FIELDS TERMINATED BY '|' LINES TERMINATED BY '\n';
LOAD DATA LOCAL INFILE '~/tpchdata/nation.tbl' INTO TABLE NATION FIELDS TERMINATED BY '|' LINES TERMINATED BY '\n';
LOAD DATA LOCAL INFILE '~/tpchdata/part.tbl' INTO TABLE PART FIELDS TERMINATED BY '|' LINES TERMINATED BY '\n';
LOAD DATA LOCAL INFILE '~/tpchdata/supplier.tbl' INTO TABLE SUPPLIER FIELDS TERMINATED BY '|' LINES TERMINATED BY '\n';
LOAD DATA LOCAL INFILE '~/tpchdata/partsupp.tbl' INTO TABLE PARTSUPP FIELDS TERMINATED BY '|' LINES TERMINATED BY '\n';
LOAD DATA LOCAL INFILE '~/tpchdata/customer.tbl' INTO TABLE CUSTOMER FIELDS TERMINATED BY '|' LINES TERMINATED BY '\n';
LOAD DATA LOCAL INFILE '~/tpchdata/orders.tbl' INTO TABLE ORDERS FIELDS TERMINATED BY '|' LINES TERMINATED BY '\n';
LOAD DATA LOCAL INFILE '~/tpchdata/lineitem.tbl' INTO TABLE LINEITEM FIELDS TERMINATED BY '|' LINES TERMINATED BY '\n';

10. 右键项目qgen，选择生成，然后将dbgen\Debug目录下的qgen.exe拷贝到dbgen目录下，并把dbgen\queries文件夹中的sql文件拷出来到目录dbgen\下；

11. 利用命令“qgen-d 1 > _1.sql”生成实例化的SQL，一直运行22次便可得到实例化的22个query（每次需指定query的序号）。

12. 然后就可以利用实例化的query进行测试啦。
