批处理数据--db2备份数据
如果要插入数据，前提先根据主键删除记录，然后在插入。
批处理包含两个必要文件
init.bat和start.bat
文档内容如下
init.bat内容如下
@echo on
db2 connect to cashman user db2inst1 using '1qaz!QAZ'
db2 set schema db2inst1
db2 -td@ -vf update.sql>log.txt //将执行结果输出到log.txt
db2 -td@ -vf delete.sql>>log.txt //注意，如果是>会覆盖上一个执行结果日志，如果是>>会在上一个日志的基础上追加
db2 -td@ -vf insert.sql>>log.txt
db2 import from t_user.sql of del modified by codepage=1386 insert into t_user(corpid,userid)>>log.txt //这个定义参照db2set -all设置，可以保证插入数据全部显示
db2 commit
db2 terminate
pause
exit
start.bat内容如下
@echo off
db2cmd init.bat
exit
编辑的每一个语句以@结束，insert以最后一条记录为准后@结束
db2 import from t_user.sql of del modified by codepage=1386 insert into t_user(corpid,userid)>>log.txt
用到这句话时，t_user.sql用记事本打开
"武金晶","010184","901010200",5,"120108198502280023","13662003683","965EB72C92A549DD","01"
"强雅薇","012111","901010200",5,"120106199107267023","13802098032","965EB72C92A549DD","01"
无需加@，执行结果在log日志中显示
