1、下載tpch
在這個網站下載：
https://github.com/electrum/tpch-dbgen
解壓：
unzip tpch_2_16_0v1.zip
2、安裝tpch
$cd tpch_2_17_0/dbgen
$vim makefile.suite
更改其中參數：
CC = gcc
DATABASE =SQLSERVER
VECTORWISE =LINUX
WORKLOAD =TPCH
3、安裝
$make
4、生成1G的數據
./dbgen -s 1 -f -T L
5、連接PG數據庫test（用postgres用戶）
/psql test
6、創建表
創建表語句在dss.dll中，找到打開並複製
gedit dss.dll
將複製的創建表語句黏貼出來：
CREATE TABLE NATION ( N_NATIONKEY INTEGER NOT NULL,
N_NAME CHAR(25) NOT NULL,
N_REGIONKEY INTEGER NOT NULL,
N_COMMENT VARCHAR(152));
CREATE TABLE REGION ( R_REGIONKEY INTEGER NOT NULL,
R_NAME CHAR(25) NOT NULL,
R_COMMENT VARCHAR(152));
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 );
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);
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 );
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);
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);
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);7、加工數據
1）將測試數據轉換爲postgresql識別的格式，刪除末尾的分隔符|
$for i in `ls *.tbl`; do sed ‘s/|$//’ $i > ${i/tbl/csv}; done
2）查看剛纔另存爲csv格式的數據是否存在
$ll -rth *.csv
3）把包含csv文件的目錄，軟鏈接到/tmp/dss-data。tpch-pg腳本中一會要用到這個目錄
\$pwd
/home/digoal/tpch/tpch_2_17_0/dbgen
\$ln -s /home/digoal/tpch/tpch_2_17_0/dbgen /tmp/dss-data
8、導入數據
test=# \copy customer from '/home/scidb/Downloads/tpch-dbgen-master/customer.csv'with CSV DELIMITER '|';
COPY 150000
test=# \copy supplier from '/home/scidb/Downloads/tpch-dbgen-master/supplier.csv'with CSV DELIMITER '|';
COPY 10000
test=# \copy nation from '/home/scidb/Downloads/tpch-dbgen-master/nation.csv'with CSV DELIMITER '|';
COPY 25
test=# \copy region from '/home/scidb/Downloads/tpch-dbgen-master/region.csv'with CSV DELIMITER '|';
COPY 5
test=# \copy part from '/home/scidb/Downloads/tpch-dbgen-master/part.csv'with CSV DELIMITER '|';
COPY 200000
test=# \copy partsupp from '/home/scidb/Downloads/tpch-dbgen-master/partsupp.csv'with CSV DELIMITER '|';
COPY 800000
test=# \copy order from '/home/scidb/Downloads/tpch-dbgen-master/order.csv'with CSV DELIMITER '|';
/home/scidb/Downloads/tpch-dbgen-master/order.csv: No such file or directory
test=# \copy orders from '/home/scidb/Downloads/tpch-dbgen-master/orders.csv'with CSV DELIMITER '|';
COPY 1500000
test=# \copy lineitem from '/home/scidb/Downloads/tpch-dbgen-master/lineitem.csv'with CSV DELIMITER '|';
COPY 6001215
9、報錯
ERROR: could not open file “/home/scidb/Downloads/tpch-dbgen-master/customer.csv” for reading: Permission denied
解決：（全用過，不知道哪個管用了，都寫下來）
1） chmod a+rX /home/scidb/Downloads /home/scidb/Downloads/tpch-dbgen-master /home/scidb/Downloads/tpch-dbgen-master/customer.csv
2） chown postgres /home/scidb/Downloads/tpch-dbgen-master/customer.csv
3）最重要的是不能直接寫copy！要寫/copy！
10、添加外鍵、主鍵
載入數據後，就可以添加外鍵、主鍵；對每張表添加外鍵、主鍵，修改tpch-dbgen文件夾中的dss.ri(用文本編輯器打開)，將添加外鍵和主鍵的信息都按照以下修改，並註釋掉圖上的connect to tpcd
-- For table REGION
ALTER TABLE REGION
ADD PRIMARY KEY (R_REGIONKEY);
-- For table NATION
ALTER TABLE NATION
ADD PRIMARY KEY (N_NATIONKEY);
ALTER TABLE NATION
ADD FOREIGN KEY (N_REGIONKEY) references REGION;
COMMIT WORK;
-- For table PART
ALTER TABLE PART
ADD PRIMARY KEY (P_PARTKEY);
COMMIT WORK;
-- For table SUPPLIER
ALTER TABLE SUPPLIER
ADD PRIMARY KEY (S_SUPPKEY);
ALTER TABLE SUPPLIER
ADD FOREIGN KEY (S_NATIONKEY) references NATION;
COMMIT WORK;
-- For table PARTSUPP
ALTER TABLE PARTSUPP
ADD PRIMARY KEY (PS_PARTKEY,PS_SUPPKEY);
COMMIT WORK;
-- For table CUSTOMER
ALTER TABLE CUSTOMER
ADD PRIMARY KEY (C_CUSTKEY);
ALTER TABLE CUSTOMER
ADD FOREIGN KEY (C_NATIONKEY) references NATION;
COMMIT WORK;
-- For table LINEITEM
ALTER TABLE LINEITEM
ADD PRIMARY KEY (L_ORDERKEY,L_LINENUMBER);
COMMIT WORK;
-- For table ORDERS
ALTER TABLE ORDERS
ADD PRIMARY KEY (O_ORDERKEY);
COMMIT WORK;
-- For table PARTSUPP
ALTER TABLE PARTSUPP
ADD FOREIGN KEY (PS_SUPPKEY) references SUPPLIER;
COMMIT WORK;
ALTER TABLE PARTSUPP
ADD FOREIGN KEY (PS_PARTKEY) references PART;
COMMIT WORK;
-- For table ORDERS
ALTER TABLE ORDERS
ADD FOREIGN KEY (O_CUSTKEY) references CUSTOMER;
COMMIT WORK;
-- For table LINEITEM
ALTER TABLE LINEITEM
ADD FOREIGN KEY (L_ORDERKEY) references ORDERS;
COMMIT WORK;
ALTER TABLE LINEITEM
ADD FOREIGN KEY (L_PARTKEY,L_SUPPKEY) references PARTSUPP;
COMMIT WORK;
11、測試語句
1）創建一個queries目錄，用於存放轉換後的tpc-h 測試SQL
$mkdir dss/queries
2）生成測試SQL
$for q in `seq 1 22`
do
DSS_QUERY=dss/templates ./qgen $q >> dss/queries/$q.sql
sed 's/^select/explain select/' dss/queries/$q.sql > dss/queries/$q.explain.sql
cat dss/queries/$q.sql >> dss/queries/$q.explain.sql;
done12、就完成了
查看錶中的信息是否修改\d cunstomer
