inserting enum column into mysql from Perl program

[baperl]

hi, I am trying to execute the following command in my Perl program

my $ins_rec = "INSERT INTO $tbl_name (col1, col2, col3, col4, col5, co
+l6, col7) VALUES (?,?,?,?,?,?,?);";


$sth=$dbh->prepare($ins_rec) or die $dbh->errstr;

$sth->execute($col1, $col2, $col3, $col4, $col5, $col6, $col7) or die 
+$sth->errstr;

in my table, col7 is described as

col7 ENUM('N','Y') NOT NULL DEFAULT 'N'

however, when I execute the program, I get the following error:

Global symbol "$col7" requires explicit package name at test.pl line 9
+6.
Execution of test.pl aborted due to compilation errors.

of course, when I remove col7, my program works fine. So, how do I fix the statement so I can insert col7 into my table. thanks!

This means you never declared nor defined $col7. The following is missing from your code:

my $col7 ;

Note that $col7 will remain undefined until you set it to something else. DBI will treat undef as NULL while executing SQL statements.
