Greenplum同步到Oracle - 数据库编程

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。

#!/bin/sh
#copy_gp_2_ora.sh
if [ $# -ne 1 ]; then
echo "Usage: sh $0 tablename"
exit 1
fi
TABLENAME=$1

psql -h -U < \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-
