Perl used for Oracle?

I will write some perl script to do Oracle admin job. I'm new to Perl. My questions:

1. In perl, how can I call OS(in Unix) command, such as 'sqlplus'?
2. Also, how can I 'select * from v$database' after I enter 'sqlplus' in perl?
3. which book is best for Perl?

Thanks a lot!!!!! Pls also email me a copy. Received on Tue Nov 23 1999 - 21:26:25 CST
