NAME
       Class::DBI::Query - Deprecated SQL manager for Class::DBI

SYNOPSIS
               my $sth = Class::DBI::Query
                       ->new({
                               owner => $class,
                               sqlname => $type,
                               essential => \@columns,
                               where_columns => \@where_cols,
                       })
                       ->run($val);

DESCRIPTION
       This abstracts away many of the details of the Class::DBI underlying
       SQL mechanism. For the most part you probably don't want to be
       interfacing directly with this.

       The underlying mechanisms are not yet stable, and are subject to change
       at any time.

OPTIONS
       A Query can have many options set before executing. Most can either be
       passed as an option to new(), or set later if you are building the
       query up dynamically:

   owner
       The Class::DBI subclass that 'owns' this query. In the vast majority of
       cases a query will return objects - the owner is the class of which
       instances will be returned.

   sqlname
       This should be the name of a query set up using set_sql.

   where_clause
       This is the raw SQL that will substituted into the 'WHERE %s' in your
       query. If you have multiple %s's in your query then you should supply a
       listref of where_clauses. This SQL can include placeholders, which will
       be used when you call run().

   essential
       When retrieving rows from the database that match the WHERE clause of
       the query, these are the columns that we fetch back and pre-load the
       resulting objects with. By default this is the Essential column group
       of the owner class.

METHODS
   where()
               $query->where($match, @columns);

       This will extend your 'WHERE' clause by adding a 'AND $column = ?' (or
       whatever $match is, isntead of "=") for each column passed. If you have
       multiple WHERE clauses this will extend the last one.
