There are many, many ways to accomplish what you wish. But you also have to ask yourself if it really worth your time to write a script for this task when you should have reliable configuration tools. Having said that, here is a small script that demonstrates using DBI's HandleError hook. The code will stop after take the first successful connection, which may not be quite what you want:

use strict; use warnings; use DBI; use Data::Dumper; sub dbi_error { warn "failed with @_\n" } my @attempts = ( [qw( wrong wrong )], # this would be a wrong user/pass [qw( correct pass )], # this would be a correct user/pass [qw( wrong wrong )], # and another wrong one ); my $dbh; for (@attempts) { $dbh ||= DBI->connect( qw(DBI:mysql:information_schema:localhost), @$_, { HandleError => sub { dbi_error( @$_ ) } }, ); } print Dumper $dbh->selectall_arrayref('select * from TABLES', {Slice=> +{}});
But as you can see, DBI does indeed allow you to control what happens when an error occurs. You do not necessarily need to wrap the call in a try-catch block. Hope this helps!

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • 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.
