SP2-0306：无效选项。通过shell脚本连接到DB时

Question

我有一个shell脚本，通过sqlplus连接到它来查询数据库，但我收到了无效选项错误.Below是我的脚本。

set -x
TodayDate=`date +%d-%m-%Y`

read_sql_stmt()
{
        typeset stmt=$1
        typeset login=$2
        echo "
                set feedback off verify off heading off pagesize 0
                $stmt;
                exit
                " | sqlplus -s login
}
#USER_PASS="bnpqa/bnpqa@MTS12C"
echo $USER_PASS
dnsmDate=`read_sql_stmt "select distinct(to_char(trunc(nse_update_date),'DD-MM-YYYY')) FROM DRV_NSE_SECURITY_MASTER" "$USER_PASS"`

echo "$dnsmDate"
if [ $TodayDate -gt $dnsmDate ]
then
echo "Success"
fi;

以下是使用set -x

进行调试时的输出

虽然我可以通过sqlplus用户名/密码@ DBNAME直接从我的终端连接到DB。
