Oracle 中的 sqlldr 错误

Question

目前，我正在使用sqlldr userid= {user}/{pass}@{SID} 将文件加载到数据库中，并且此注释在 bash 文件中。

密码由第三个 lib 框架生成。

但是，我发现有时会出现以下错误，

export TNS_ADMIN=/opt/config/uat/  
export PATH=$PATH:$ORACLE_HOME/bin 
sqlldr  userid=M_UAT/YAu8D=5r@My_UAT  
ERR>LRM-00116: syntax error at 'M_UAT/YAu8D' following '='

发现密码中有一个特殊字符=，

我查了一下，似乎sqlplus可以通过userid= ={user}/\"{pass}\"@{SID}避免这个异常

但是 sqlldr 不能。

这里有人有想法吗？

Answer 1

sqlplus 使用引号中的用户名和密码建立连接。仅当名称不带引号时，sqlloader(sqlldr) 才会连接到数据库。 密码只能在引号中包含@!= 字符，例如

password=\"YAu8D=5r\"
password=\"@!YAu8D=5r@\"

示例 1

username=HR
password=\"YAu8D=5r\"

修改密码

oracle@esmd:~> sqlplus / as sysdba
