Hi,


Actually i want to check if a environmental variable in perl script,
which is present in oracle database has been already set its path in
hash table in perl.

that is i have to query the database server and check whether it has
been set as environment variable or not.

so basically i want to check with if statement to database server name
and a loop to check for all variables present in perl by quering the
database....to find those variables has been set as environment
variable or not.....if present it should be in hash table....

so i need the syntax and proper logic to test this......

it would be great if anyone can help me out...
