一、Linux下使用DBGEN 和QGEN 程序创建数据与查询脚本

1、下载工具压缩包
http://www.tpc.org/tpc_documents_current_versions/current_specifications.asp

image.png

2、将压缩包放置到指定目录下，解压压缩包

unzip tpc-h-tool.zip

3、修改makefile文件内容
–在CC后填写gcc
–在DATABASE后填写Oracle
–在MACHINE后填写LINUX
–在WORKLOAD后填写TPCH

################
## CHANGE NAME OF ANSI COMPILER HERE
################
CC      = gcc
# Current values for DATABASE are: INFORMIX, DB2, TDAT (Teradata)
#                                  SQLSERVER, SYBASE, ORACLE, VECTORWISE
# Current values for MACHINE are:  ATT, DOS, HP, IBM, ICL, MVS, 
#                                  SGI, SUN, U2200, VMS, LINUX, WIN32 
# Current values for WORKLOAD are:  TPCH
DATABASE=ORACLE     
MACHINE = LINUX         
WORKLOAD = TPCH     

4、执行编译

make

5、执行数据生成操作
— -s后填写的是SF的数量，TPC- H 中使用SF 描述数据量，1SF 对应1 GB 单位，SF 由低到高依次是1、10、30、100、300、1 000、3 000、10 000。
— time是输出产生数据的时间，可以忽略直接写为./dbgen -s 1 -vf

time ./dbgen -s 1 -vf

6、生成查询测试脚本
将默认脚本克隆到qgen程序的同级目录，执行./qgen，-s后填写的是SF的数量，不同的SF生成查询sql中的参数值会有所不同。使用DATABASE=ORACLE 编译的程序生成脚本只需改动一点即可通用于所需测试的三个数据库，因此不建议多次编译用于生成对应数据库脚本（试过在不同目录下解压编译，因创建查询脚本时使用的seed值不一样，相同的SF值生成脚本参数不一致）。

[root@dn210120 dbgen]# cp ./queries/*.sql ./
[root@dn210120 dbgen]# ./qgen -s 1 > query.sql

二、Oracle导入数据与脚本处理

1、Oracle建表脚本

CREATE TABLE PART (
    P_PARTKEY       INT NOT NULL,
    P_NAME          VARCHAR2(55),

    N_COMMENT       VARCHAR2(152)
);

CREATE TABLE SUPPLIER (
    S_SUPPKEY       INT NOT NULL,
    S_NAME          CHAR(25),
    S_ADDRESS       VARCHAR2(40),
    S_NATIONKEY     INTEGER NOT NULL, -- references N_NATIONKEY
    S_PHONE         CHAR(15),

    C_CUSTKEY       INT NOT NULL,
    C_NAME          VARCHAR2(25),
    C_ADDRESS       VARCHAR2(40),
    C_NATIONKEY     INTEGER NOT NULL, -- references N_NATIONKEY
    C_PHONE         CHAR(15),
    C_ACCTBAL       DECIMAL,
    C_MKTSEGMENT    CHAR(10),
    C_COMMENT       VARCHAR2(117)
);

CREATE TABLE ORDERS (
    O_ORDERKEY      INT NOT NULL,
    O_CUSTKEY       INTEGER NOT NULL, -- references C_CUSTKEY
    O_ORDERSTATUS   CHAR(1),
    O_TOTALPRICE    DECIMAL,
    O_ORDERDATE     DATE,
    O_ORDERPRIORITY CHAR(15),
    O_CLERK         CHAR(15),
    O_SHIPPRIORITY  INTEGER,
    O_COMMENT       VARCHAR2(79)
);

CREATE TABLE LINEITEM (
    L_ORDERKEY      INTEGER NOT NULL, -- references O_ORDERKEY
    L_PARTKEY       INTEGER NOT NULL, -- references P_PARTKEY (compound fk to PARTSUPP)
    L_SUPPKEY       INTEGER NOT NULL, -- references S_SUPPKEY (compound fk to PARTSUPP)
    L_LINENUMBER    INTEGER NOT NULL,
    L_QUANTITY      DECIMAL,
    L_EXTENDEDPRICE DECIMAL,
    L_DISCOUNT      DECIMAL,
    L_TAX           DECIMAL,
    L_RETURNFLAG    CHAR(3),
    L_LINESTATUS    CHAR(3),
    L_SHIPDATE      DATE,
    L_COMMITDATE    DATE,
    L_RECEIPTDATE   DATE,
    L_SHIPINSTRUCT  CHAR(25),
    L_SHIPMODE      CHAR(10),
    L_COMMENT       VARCHAR2(44)
);

CREATE TABLE REGION (
    R_REGIONKEY INT NOT NULL,
    R_NAME      CHAR(25),
    R_COMMENT   VARCHAR2(152)
);

2、Oracle导入数据语句
使用sqlldr执行ctl文件进行数据导入，一个LOAD DATA语句一个ctl文件。LOAD DATA语句可参考一下sql。

LOAD DATA INFILE '/data/temp/part.tbl'   INTO TABLE part TRAILING NULLCOLS(
    P_PARTKEY       terminated by '|',
    P_NAME          terminated by '|',
    P_MFGR          terminated by '|',
    P_BRAND         terminated by '|',
    P_TYPE          terminated by '|',
    P_SIZE          terminated by '|',

    PS_SUPPKEY      terminated by '|',
    PS_AVAILQTY     terminated by '|',
    PS_SUPPLYCOST   terminated by '|',
    PS_COMMENT      terminated by '|'
)

LOAD DATA INFILE '/data/temp/customer.tbl'   INTO TABLE customer TRAILING NULLCOLS (
    C_CUSTKEY       terminated by '|',
    C_NAME          terminated by '|',

    O_ORDERKEY      terminated by '|',
    O_CUSTKEY       terminated by '|',
    O_ORDERSTATUS   terminated by '|',
    O_TOTALPRICE    terminated by '|',
    O_ORDERDATE     DATE "YYYY-MM-DD",
    O_ORDERPRIORITY terminated by '|',
    O_CLERK         terminated by '|',
    O_SHIPPRIORITY  terminated by '|',
    O_COMMENT       terminated by '|'
)

LOAD DATA INFILE '/data/temp/lineitem.tbl'   INTO TABLE lineitem  fields terminated by "|" TRAILING NULLCOLS(
        L_ORDERKEY              terminated by "|" ,
        L_PARTKEY               terminated by "|",
        L_SUPPKEY               terminated by "|",
        L_LINENUMBER    terminated by "|",
        L_QUANTITY              terminated by "|",

        L_RETURNFLAG    CHAR(3) ,
        L_LINESTATUS    CHAR(3) ,
        L_SHIPDATE              DATE "YYYY-MM-DD" ,
        L_COMMITDATE    DATE "YYYY-MM-DD" ,
        L_RECEIPTDATE   DATE "YYYY-MM-DD" ,
        L_SHIPINSTRUCT  CHAR(25) ,
        L_SHIPMODE              CHAR(10) ,
        L_COMMENT               CHAR(44)
)


LOAD DATA INFILE '/data/temp/region.tbl'   INTO TABLE region  (
    R_REGIONKEY terminated by '|',
    R_NAME      terminated by '|',
    R_COMMENT   terminated by '|'
)

执行sqlldr将数据导入到数据库中，执行sqlldr userid=user/password@database control=ctl文件的绝对路径 log=/data/temp/load_tpch.log

sqlldr userid=tpch10g/test@utf8db control=/data/temp/load_tpch_part.ctl rows=10000 bindsize=20971520 direct=true  log=/data/temp/part.log
sqlldr userid=tpch10g/test@utf8db control=/data/temp/load_tpch_customer.ctl rows=10000 bindsize=20971520 direct=true  log=/data/temp/customer.log
sqlldr userid=tpch10g/test@utf8db control=/data/temp/load_tpch_lineitem.ctl rows=10000 bindsize=20971520 direct=true  log=/data/temp/lineitem.log

alter table nation   add constraint fk_tpcc_8 foreign key(n_regionkey) references region(r_regionkey);

四、PostgreSQL导入数据与脚本处理

1、PostgreSQL建表脚本

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




CREATE TABLE NATION (
N_NATIONKEY  SERIAL NOT NULL,
N_NAME  CHAR(25),
N_REGIONKEY  INTEGER NOT NULL,  -- references R_REGIONKEY
N_COMMENT  VARCHAR(152)
);


CREATE TABLE SUPPLIER (
S_SUPPKEY  SERIAL NOT NULL,
S_NAME  CHAR(25),
S_ADDRESS   VARCHAR(40),
S_NATIONKEY   INTEGER NOT NULL, -- references N_NATIONKEY
S_PHONE   CHAR(15),
S_ACCTBAL    DECIMAL,
S_COMMENT   VARCHAR(101)
);

CREATE TABLE PARTSUPP (
PS_PARTKEY   INTEGER NOT NULL, -- references P_PARTKEY
PS_SUPPKEY   INTEGER NOT NULL, -- references S_SUPPKEY
PS_AVAILQTY    INTEGER,
PS_SUPPLYCOST   DECIMAL,
PS_COMMENT  VARCHAR(199)
);

CREATE TABLE CUSTOMER (
C_CUSTKEY   SERIAL NOT NULL,
C_NAME    VARCHAR(25),
C_ADDRESS    VARCHAR(40),
C_NATIONKEY    INTEGER NOT NULL, -- references N_NATIONKEY
C_PHONE     CHAR(15),
C_ACCTBAL    DECIMAL,
C_MKTSEGMENT    CHAR(10),
C_COMMENT    VARCHAR(117)
);

CREATE TABLE ORDERS   (
O_ORDERKEY  SERIAL   NOT NULL,
O_CUSTKEY   INTEGER   NOT NULL,   --   references   C_CUSTKEY
O_ORDERSTATUS  CHAR(1),
O_TOTALPRICE  DECIMAL,
O_ORDERDATE   DATE,
O_ORDERPRIORITY   CHAR(15),
O_CLERK   CHAR(15),
O_SHIPPRIORITY   INTEGER,
O_COMMENT  VARCHAR(79)
);

CREATE TABLE LINEITEM (
L_ORDERKEY     INTEGER NOT NULL, -- references O_ORDERKEY
L_PARTKEY    INTEGER NOT NULL, -- references P_PARTKEY (compound fk to PARTSUPP)
L_SUPPKEY    INTEGER NOT NULL, -- references S_SUPPKEY (compound fk to PARTSUPP)
L_LINENUMBER   INTEGER NOT NULL,
L_QUANTITY    DECIMAL,
L_EXTENDEDPRICE    DECIMAL,
L_DISCOUNT   DECIMAL,

L_RECEIPTDATE    DATE,
L_SHIPINSTRUCT   CHAR(25),
L_SHIPMODE   CHAR(10),
L_COMMENT   VARCHAR(44)
);

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

2、PostgreSQL导入数据语句
PostgreSQL导入数据前需要先将dbgen生成的数据中每一行最后一个“|”分隔符去除，否则无法正常导入，批量“|”去除的方式可以参考以下脚本。

--将tbl文件转换为csv，在liunx下，进入tbl所在文件夹执行以下命令即可
for i in `ls *.tbl`; do sed 's/|$//' $i > ${i/tbl/csv}; done

数据导入使用COPY命令

COPY customer(C_CUSTKEY,C_NAME,C_ADDRESS,C_NATIONKEY,C_PHONE,C_ACCTBAL,C_MKTSEGMENT,C_COMMENT) FROM '/data/tpch/tpch/data/10g/customer.csv' delimiter '|' ;
COPY lineitem(L_ORDERKEY,L_PARTKEY,L_SUPPKEY,L_LINENUMBER,L_QUANTITY,L_EXTENDEDPRICE,L_DISCOUNT,L_TAX,L_RETURNFLAG,L_LINESTATUS,L_SHIPDATE,L_COMMITDATE,L_RECEIPTDATE,L_SHIPINSTRUCT,L_SHIPMODE,L_COMMENT) FROM '/data/tpch/tpch/data/10g/lineitem.csv' delimiter '|' ;
COPY nation(N_NATIONKEY,N_NAME,N_REGIONKEY,N_COMMENT) FROM   '/data/tpch/tpch/data/10g/nation.csv' delimiter '|' ;
COPY orders(O_ORDERKEY,O_CUSTKEY,O_ORDERSTATUS,O_TOTALPRICE,O_ORDERDATE,O_ORDERPRIORITY,O_CLERK,O_SHIPPRIORITY,O_COMMENT) FROM   '/data/tpch/tpch/data/10g/orders.csv' delimiter '|' ;
COPY partsupp(PS_PARTKEY,PS_SUPPKEY,PS_AVAILQTY,PS_SUPPLYCOST,PS_COMMENT) FROM '/data/tpch/tpch/data/10g/partsupp.csv' delimiter '|' ;
COPY part(P_PARTKEY,P_NAME,P_MFGR,P_BRAND,P_TYPE,P_SIZE,P_CONTAINER,P_RETAILPRICE,P_COMMENT) FROM     '/data/tpch/tpch/data/10g/part.csv' delimiter '|' ;
COPY region(R_REGIONKEY,R_NAME,R_COMMENT) FROM   '/data/tpch/tpch/data/10g/region.csv' delimiter '|' ;
COPY supplier(S_SUPPKEY,S_NAME,S_ADDRESS,S_NATIONKEY,S_PHONE,S_ACCTBAL,S_COMMENT) FROM '/data/tpch/tpch/data/10g/supplier.csv' delimiter '|' ;

3、PostgreSQL创建主外键语句

--PRIMARY KEY
ALTER TABLE PART ADD PRIMARY KEY (P_PARTKEY);
ALTER TABLE SUPPLIER ADD PRIMARY KEY (S_SUPPKEY);
ALTER TABLE PARTSUPP ADD PRIMARY KEY (PS_PARTKEY, PS_SUPPKEY);
