shell脚本sql赋值

以下脚本功能是用shell脚本登录sqlplus连接oracle，将执行sql语句查询的结果赋值给shell脚本中的变量

 #!/bin/bash
 echo "开始连接数据库..."
 sqlplus -S "name/password" << !
 set pagesize 0
 set verify off
 set feedback off
 set echo off
 col coun new_value v_coun
 select count(*) coun from src.global_info where batchdate='20180309' and status='0';
 exit v_coun
 !
 value="$?"
 echo '查询总数为:'$value
 if [ $value == 0 ];
 then
 echo "数据库状态错误，开始更新batchdate和status"
 sqlplus -S "nbms_user2/nbms_user2" << !
 update src.global_info set batchdate='20180305', status='0' where id =1;
 select count(*) coun from src.global_info where batchdate='20180309' and status='0';
 exit
 !
 echo "开始调用跑批脚本"
 else
                 echo "数据库状态正确!开始调用跑批脚本"
                 #sh BMSRUNALL.sh
