利用python生成导入文件

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import random
path = r"F:\alien_invasion\DATA_BLKLISTS01A.del"
list = open(path,'w')
count1 = 1
print("开始执行！" )
for i in range(10000000):
    i = i+1
    count1 +=1
    randomcount = random.randint(0,9)
    print("""%s,"8613%s%08d",1,1,"remarks",""" % (i,str(randomcount),count1))
    list.writelines("""%s,"8613%s%08d",1,1,"remarks",\n""" % (i,str(randomcount),count1))
    #函数 writelines(list）函数writelines可以将list写入到文件中，但是不会在list每个元素后加换行符，所以如果想每行都有换行符的话需要自己再加上。
print ("执行结束！")
list.close()

利用db2 load工具导入数据

db2 connect to  数据库名

创建500w数据表

db2 "CREATE TABLE XIFENFEI_LOAD(col1  INT NOT NULL primary key,
                                col2  CHAR(100) NOT NULL,
                                col3  VARCHAR(20) NOT NULL,
                                col4  VARCHAR(20) NOT NULL,
                                col5  VARCHAR(20) NOT NULL)"
                               
导入500万数据                                                                                                                
db2 load from /tmp/DATA_BLKLISTS01.del of del insert into XIFENFEI_LOAD1 nonrecoverable

创建1000w数据表
db2 "CREATE TABLE XIFENFEI_LOAD4(col1 BIGINT  NOT NULL primary key,
                                col2  CHAR(100) NOT NULL,
                                col3  VARCHAR(20) NOT NULL,
                                col4  VARCHAR(20) NOT NULL,
                                col5  VARCHAR(20) NOT NULL)" 
导入1000万数据
