from v * ERROR at line 1: ORA-00942: table or view does not exist

在运行一个备份脚本的时候，当执行在v$动态性能视图时，就会报错，如果单独运行该sql语句的时候就不会有问题 ，具体情况如下：

#/bin/bash

$ORACLE_HOME/bin/sqlplus -s "/ as sysdba" << !

… …

spool &fil

select 'host cp ' || name ||' &dir' from v$datafile;

… …

spool off;

exit

!

select 'host cp ' || name ||' /u01/backup/cold' from v

*

ERROR at line 1:

ORA-00942: table or view does not exist

Solution:

Escape the $ in v$datafile with a like this v$datafile,

select 'host cp ' || name ||' &dir' from v$datafile;
