invoking sqlplus from perl show no output

P: 9
Hi,

I want to catch a select-result into perl-variable, like this (on Linux):

$C = system ("sqlplus $DBUSER/$DBPW \@getcolnam.sql $TABNAM $TABOWNER ");

Wenn I run this, I see Oracle's output properly, but I can't catch the result in a perl variable. $C is empty, I also tried @C but there is nothing in.

I used exactly this mehtod years ago without any problems.

How can I findout, what the problem is ? How get more feedback from system call ?

I'm not a real UNIX-Freak and have no ideas about all those UNIX-system internals to find out, I'm just an oracle-guy.

thanks for any tip, Lao De

If you are wanting to capture the output of a system run command, you don't want to use the system() function as all it returns is the exit status of what it ran. Instead, just use backtics as follows:

Expand|Select|Wrap|Line Numbers
  1. $C = `sqlplus $DBUSER/$DBPW \@getcolnam.sql $TABNAM $TABOWNER`;
  2.
