For 1), you can store the $sth after you create it once; when you next use that to execute() a SQL statement, the query still remains, though the placeholder values will be replaced with the appropriate values for the new statement. So simply create these as private variables in your Guest pacakge.

For 2), you can create a function "dbi()", which when called, either creates the $dbi connection if none exists and returns it, or returns the existing dbi connection. Then in your various classes in Guest, call something like:

my $sth = Controller->dbi()->prepare( "SQL STATEMENT" )
  or die DBI->errstr;

You no longer need to pass the $dbi to each method.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
