NAME

       Data::Phrasebook::SQL::Query - Query Extension to the SQL/DBI Phrasebook Model.

SYNOPSIS

	   my $q = $book->query( 'find_author' );
	   my $q = $book->query( 'find_author', 'Dictionary' );

DESCRIPTION

       An extension to the SQL class to specifically handle the DBI interface for each query requested.

CONSTRUCTOR

   new
       Not to be accessed directly, but via the parent Data::Phrasebook, by specifying the class as SQL.

METHODS

   sql
       Get/set the current "sql" statement, in a form suitable for passing straight to DBI.

   sth
       Get/set the current statement handle.

   args
       Return list of arguments that will be used as bind parameters to any placeholders. Any given arguments will replace the whole list.

       Returns list in list context, arrayref in scalar.

   order
       As for "args", but regarding the corresponding list of argument names.

       The assorted "order_XXX" methods are supported as for "args_XXX".

   dbh
       Get/set the database handle.

PREPARATION 
/ EXECUTING METHODS
   execute
       Executes the query. Returns the result of "DBI::execute".

       Any arguments are given to "order_args" with the return of that method being used as arguments to "DBI::execute". If no arguments, uses
       those already specified.

       Calls "prepare" if necessary.

   order_args
       Given a hash or hashref of keyword to value mappings, organises an array of arguments suitable for use as bind parameters in the order
       needed by the query itself.

   prepare
       Prepares the query for execution. This method is called implicitly in most cases so you generally don't need to know about it.

   rebind
       Rebinds any bound values. Lets one pass a scalar reference in the arguments to "order_args" and have the bound value update if the original
       scalar changes.

       This method is not needed externally to this class.

DELEGATED METHODS

       Any method not mentioned above is given to the statement handle.

       All these delegations will implicitly call "prepare".

SEE ALSO

       Data::Phrasebook, Data::Phrasebook::SQL.

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.
