[vox-tech] sqlite + perl - wierd unrecognized token error

[Peter Jay Salzman]

I'm getting an error message that I don't know how to fix:


   $ ./driver.pl 

   Grade Utility

   2. Add a student
   3. Modify a student

   Choice: 1
   Enter semester: 20051
   Enter course: SAPHY223
   Enter Course Desc: Theoretical Dilithium Crystal Designs
   Enter college: Starfleet Academy
   Enter reference: 10543
   DBD::SQLite::db do failed: unrecognized token: ":" at Create_Tables.pm line
   52, <> line 6.




Excerpt from driver.pl:


   sub Create_Course()
   {
      my %course;

      print "Enter semester: ";
      $course{semester} = <>;

      print "Enter course: ";
      $course{course} = <>;

      print "Enter Course Desc: ";
      $course{course_desc} = <>;

      print "Enter college: ";
      $course{college} = <>;

      print "Enter reference: ";
      $course{reference} = <>;

      foreach (keys %course) { chomp $course{$_}; }

      Create_Database(\%course);
   }




Excerpt from Create_Tables.pm:


   sub Create_Database(%)
   {
      my ($course) = @_;

      my $table_name =
         "$course->{semester}.$course->{course}.$course->{reference}.dat";

      die "Database file already exists" if -e $table_name;

      my $dbh = DBI->connect("dbi:SQLite:$table_name");

      # Create the course table
      #
      $dbh->do("
         CREATE TABLE course (
            semester    VARCHAR(10),
            course      VARCHAR(10),
            course_desc VARCHAR(10),
            college     VARCHAR(20),
            reference   INT
         )
      ");


      # Populate the course table.  FIXME.  Clunky.
      #
      $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} )
         )
      ");

   }





I printed out a trace log at level 3, but it didn't give any clues.
Everything looked more or less normal, until:

    -> execute for DBD::SQLite::st (DBI::st=HASH(0x8407760)~0x840773c)
thr#814c008  
sqlite error 1 recorded: unrecognized token: ":"
    !! ERROR: 1 'unrecognized token: ":"' (err#0)
    <- execute= undef at DBI.pm line 1436 via Create_Tables.pm line 52

thr#814c008

       ERROR: 1 'unrecognized token: ":"' (err#0)



I'm brand spanking new to this stuff.  Any ideas on what's going on?  I
don't really see any ":" anywhere except for the DBI connection statement.

Thanks!
Pete
