Greenplum同步到Oracle脚本

开发提出需要从Greenplum同步到Oracle的解决方案，写了个脚本用于定时调度处理。

脚本如下：

#!/bin/sh
 #copy_gp_2_ora.sh
 if [ $# -ne 1 ]; then
    echo "Usage: sh $0 tablename"
    exit 1
 fi
 TABLENAME=$1
 
 psql -h <host> -U <user> <db><<EOF
 \timing off
 set client_encoding='gb18030';
 \copy $TABLENAME to '/home/oracle/$TABLENAME.txt' csv
 \q
 EOF
 
 echo "load data
 infile '$TABLENAME.txt' discardfile '$TABLENAME.dis'
 append
 into table $TABLENAME
 fields terminated by ','
 optionally enclosed by '\"'
 (id)">"$TABLENAME.ctl"
 
 sqlldr system/000000 control="$TABLENAME.ctl" log="$TABLENAME.log"
 -EOF-
