The alternate syntax (database=$tablename) didn't generate any errors, so at
least the dbi driver for sqlite understood it.  Unfortunately, it still
gives the same unrecognized token error.

DOH!!!  Now why didn't *I* think of that?!?

Choice: 1
Enter semester: qwer
Enter course: asdf
Enter Course Desc: zxc
Enter college: ve
Enter reference: sadf

      INSERT INTO course VALUES (
           DBI::db=HASH(0x83f16fc)->quote ( qwer ),
           DBI::db=HASH(0x83f16fc)->quote ( asdf ),
           DBI::db=HASH(0x83f16fc)->quote ( zxc ),
           DBI::db=HASH(0x83f16fc)->quote ( ve ),
           DBI::db=HASH(0x83f16fc)->quote ( sadf )
DBD::SQLite::db do failed: unrecognized token: ":" at Create_Tables.pm line 74, <> line 6.
Uncaught exception from user code:
        DBD::SQLite::db do failed: unrecognized token: ":" at Create_Tables.pm line 74, <> line 6.
        Create_Tables::Create_Database('HASH(0x835dcd8)') called at ./driver.pl line 66
        main::Create_Course() called at ./driver.pl line 30
        main::main_menu() called at ./driver.pl line 73
                )

Looks like

   $dbh->quote( blah )

isn't executing the quote method.  I think the problem is that I'm calling
the method inside a double quote:

   $dbh->do("
      INSERT INTO course VALUES (
         $dbh->quote ( $course->{semester} ),
         $dbh->quote ( $course->{course} ),
         $dbh->quote ( $course->{course_desc} ),
         $dbh->quote ( $course->{college} ),
         $dbh->quote ( $course->{reference} )
      )
   ");

so I think I want this, instead (or something equivalent):

   $dbh->do("
      INSERT INTO course VALUES ( " .
         $dbh->quote ( $course->{semester} )    . ", " .
         $dbh->quote ( $course->{course} )      . ", " .
         $dbh->quote ( $course->{course_desc} ) . ", " .
         $dbh->quote ( $course->{college} )     . ", " .
         $dbh->quote ( $course->{reference} )
      )
   ");


Thanks!
