My perl script is slow but works. I am considering throwing it out and building a true DB2 application with proper binds and such; however, in the meantime I want this to work as a place holder.
I looked at this documentation and it mentions:
$dbh->disconnect();
However I cannot use it because it throws this error.
Can't locate object method "disconnect" via package "dbh" (perhaps load "dbh"?) at ./ProgramTree.pl line 119.
I know my temporary application is leaking and growing because it is recursively opening database handles. Am I missing something fundamental?
That error sounds an awful lot like the sigil is missing and you're running just dbh->disconnect();
.
Look at what happens when an object doesn't have a method:
[~] perl -e'my $dbh = bless {}, q/foo/; $dbh->disconnect();' Can't locate object method "disconnect" via package "foo" at -e line 1.
Compared to when you're calling that method on the bareword "dbh":
[~] perl -e'dbh->disconnect();' Can't locate object method "disconnect" via package "dbh" (perhaps you forgot to load "dbh"?) at -e line 1.
