Informix数据库自带两个命令：load和unload

　　我们可根据方便编写sh程序进行数据的导入导出,以下两段sh程序在RedHat Linux AS 4上测试通过,应该适用于大多数Unix,Linux操作系统,放到$INFORMIX_HOME$/bin下,则使用informix登录后就可以随意使用,记得chmod +x load和chmod +x unload　

##!/bin/ksh;

if [ $# -ne 3 ]
then
  echo “error: arguments is not enough”
  echo “Usage: load dbname filename tablename”;
  echo “e.g.:  load cmsdbs custinfo.unl custinfo”;
  exit;
fi

dbname=$1;
filename=$2;
tablename=$3;

dbaccess <<!
database $dbname;
load from $filename insert into $tablename;
!

　 ##!/bin/ksh;

if [ $# -ne 3 ]
then
  echo “error: arguments is not enough”;
  echo “Usage: unload dbname filename tablename”;
  echo “e.g.:  unload cmsdbs custinfo.unl custinfo”;
  exit;
fi

dbname=$1;
filename=$2;
tablename=$3;

dbaccess <<!
database $dbname;
##!/bin/ksh;

if [ $# -ne 3 ]
then
  echo “error: arguments is not enough”;
  echo “Usage: unload dbname filename tablename”;
  echo “e.g.:  unload cmsdbs custinfo.unl custinfo”;
  exit;
fi

dbname=$1;
filename=$2;
tablename=$3;

dbaccess <<!
database $dbname;
unload to $filename select * from $tablename;
unload to $filename select * from $tablename;
