Exports (by request) hashes containing the SQL queries for each class.  The
hashes are given names that represent abbreviated versions of the classes they
support.

By  default it also exports C<db_run_ex>, which is a utility function 
facilitating database queries through the connector object.

=head1 SUBROUTINES/METHODS


=head2  db_run_ex

    db_run_ex( $connector, $sql, @parameters );

    # or

    db_run_ex( $connector, $sql, ( [ @params1 ], [ @params2 ] ) );

Pass a connector object, an SQL query, and a list of bind values.  For multiple
C<execute()> calls, pass an array of array refs instead of a flat array.  Each
anonymous array holds the bind values for a single C<< $sth->execute() >> call.

=head1 DEPENDENCIES

The dependencies for this module are the same as for L<Class::User::DBI>, from
this same distribution.  Refer to the documentation in that module for a full
description.


=head1 CONFIGURATION AND ENVIRONMENT

All of the SQL for this entire distribution is found in the 
L<Class::User::DBI::DB> module.  Any adjustments required to suit your database
engine may be made here.  This module's SQL is known to run unaltered with 
SQLite and MySQL.

=head1 DIAGNOSTICS

If you find that your particular database engine is not playing nicely with the
test suite from this module, it may be necessary to provide the database login 
credentials for a test database using the same engine that your application 
will actually be using.  You may do this by setting C<$ENV{CUDBI_TEST_DSN}>,
C<$ENV{CUDBI_TEST_DATABASE}>, C<$ENV{CUDBI_TEST_USER}>, 
and C<$ENV{CUDBI_TEST_PASS}>.

Currently the test suite tests against a SQLite database since it's such a
lightweight dependency for the testing.  The author also uses this module
with several MySQL databases.  As you're configuring your database, providing
its credentials to the tests and running the test scripts will offer really 
good diagnostics if some aspect of your database tables proves to be at odds 
with what this module needs.


=head1 INCOMPATIBILITIES

This module has only been tested on MySQL and SQLite database engines.  If you
are successful in using it with other engines, please send me an email detailing
any additional configuration changes you had to make so that I can document
the compatibility, and improve the documentation for the configuration process.
