Ahhh .... I had not seen that part of the response. Well, now they have a
sample of just how complicated it can get.

Kevin,
Thanks for the 'coprocess', I couldn't remember what it was called.
This is what I was describing in my previous email.

Actually Jared, you can by setting up a sqlplus coprocess and using unix
pipes. The routine below will get a parameter from the v$parameter table
using sqlplus.

get_db_parm()

print -p "UNION"

vRETURNED_PARM=${ORACLE_HOME}${vRETURNED_PARM#\?}

print -p "exit"
# Flush Buffer after exiting
while [ $? -eq 0 ]

printf "${vRETURNED_PARM}\n"

Omar,
If what you mean is:
"How do I send a value from sqlplus plus directly
to a variable in my shell environment?"
You can't.
What you've done is the way it is usually done.
Another way to do it is to use the '&|' korn shell mechanism.
e.g.
sqlplus -silent scott/tiger@$ORACLE_SID |&
This allows you to send commands straight to sqlplus
from the ksh command line, and retrieve the results
of queries from the cmd line.
It's not as easy as it appears. I wrote a set of shell functions
once upon a time to do this, and it gets more complex than
you expect.
The method you are currently using works ok.
Of course, you could use Perl with DBI and avoid all this
subshell nonsense.
