( #3333=superdoc: print w/ replies, xml ) Need Help??
Hi, I am relatively new to perl and now I am struggling with a very nasty and persistant problem, which already took me more than a day without any progress. No experienced Perl programmers in sight...... My problem: Given this piece of code:
my $recref = $dbh-> selectall_hashref("SELECT * FROM DSA_RECORD WHERE file_name = '$file_name'", 'RECORD_NAME'); die unless $recref;
and the following content of $recref:
.-> HASH(0x110916be8) 'DATA' => HASH(0x110916a98) 'FIELD_DELIMITER' => '<-->' 'FILE_NAME' => 'SCRAMBLETEST2.CSV' 'RECORD_NAME' => 'DATA' 'RECORD_SELECTOR' => '^1' 'SECTION_NAME' => undef
How can I put the contents of FIELD_DELIMITER in a scalar? So in the end I need a scalar ($fieldsep) with '<-->' as contents. My impression was :
$recname='DATA'; $fieldsep = $recref->{$recname}->{'FIELD_DELIMITER'};
but this results in error :
Use of uninitialized value in print .....
Please can someone help me, I am getting frustrated. Thanks in advance
