Any advice is gratefully recieved.
My problem is that I have a small database, with about
15 scripts accessing the database using Perl DBI.

Should I declare the database, username and password as
variables private to that script using my $database = 'live' etc.
This would mean that any changes to the database would mean
me visiting each script and changing the code.

OR should I create a package and declare the variables there
and then export them into each script.
This would then mean they are global variables, but at least
I only have to visit one file to change the details.

OR should I create a functions file, that is used in the main
script with a sub routine called get_db_details (and declare
the variables there) that would then return the details of the
db into variables in the main script.
This again would mean that I would only have to access one
file to make changes.

Many Thanks
Ant

• 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).
