linux shell 查询oracle数据库中的值 并返回

#!/bin/bash
dbserver=10.21.2.152
port=1521
username=COLDB2
password=creditderivative
sid=orcl





select_sql="select count(*) as rowsCount  from f3distcalccounter;"

rowsCount=`sqlplus -s ${username}/${password}@${dbserver}:${port}/${sid} <

 

   1 ： sqlplus 后面的 -s 很重要

 

   2：

set pagesize 0 heading off echo off termout off feedback off linesize 1200 colsep ","  trimspool  on trimout on
