Hello Monks, A few days ago monk Kyle helped me out with redirecting stdin to Oracle's sql*plus program. It worked like a charm. Now I am stuck about capturing the stdout messages generated by sql*plus to a scalar variable. I used IO::String and it did not work. Then I tried the following code, which also failed to capture the stdout from sql*plus. Interestingly enough, I was able to capture simple print statement's output using both IO::String as well as the code below.
use strict; use warnings; my $TEMP1; my $OLD_STDOUT_HANDLE; my $NEW_STDOUT_HANDLE; open NEW_STDOUT_HANDLE, ">&STDOUT"; close STDOUT; open STDOUT, ">", \$TEMP1; open my $pipe_fh, '|-', "sqlplus.exe -s scott/tiger\@butthead" or die "Can't open pipe: $!"; print {$pipe_fh} <<"END_OF_SQL" set echo off set lines 1000 set trims on set serverout on size 999999 set feed off exec dbms_output.put_line('Hello There'); exit; END_OF_SQL ; close $pipe_fh; close STDOUT; open STDOUT, ">&NEW_STDOUT_HANDLE"; print "6.\n"; print $TEMP1;
I would once again greatly appreciate your help.

Regards.

Ash
