Hello,
I have the following 3 database tables with a many-to-many relationship.
(Basically pictures in photoalbums). The database tables are at the
bottom.
I want to create Hibernate mappings in XDoclet with lazy-loading. I have
created Hibernate objects for each table, but I am unable to link these
using XDoclet 2 tags. I am attaching the field-identifiers below the
database tables. Do I have to use @hibernate.set, or can this be done with
the @hibernate.many-to-many somehow ?
Tables:
--Holds Pictures (primary key is BildeID)
CREATE TABLE `Bilde` (
`BildeID` int(11) NOT NULL auto_increment,
`BildeNavn` varchar(100) NOT NULL,
`BildeBeskrivelse` text NOT NULL,
`BildeMening` float NOT NULL,
`BildeLastetOpp` timestamp NOT NULL default CURRENT_TIMESTAMP on update
CURRENT_TIMESTAMP,
`BildeSistEndret` timestamp NOT NULL default '0000-00-00 00:00:00',
`BildeFilnavn` varchar(100) NOT NULL,
`BildeErPrivat` binary(1) NOT NULL,
`BildeOrginalStorrelse` float NOT NULL,
`BildeTotalStorrelse` float NOT NULL,
`Brukernavn` varchar(50) NOT NULL,
PRIMARY KEY (`BildeID`)
)
--Holds Albums (Primary key is BildeAlbumID)
CREATE TABLE `BildeAlbum` (
`BildeAlbumID` int(11) NOT NULL auto_increment,
`BildeAlbumNavn` varchar(100) NOT NULL,
`BildeAlbumBeskrivelse` text NOT NULL,
`BildeAlbumOpprettet` timestamp NOT NULL default CURRENT_TIMESTAMP on
update CURRENT_TIMESTAMP,
`BildeAlbumSistEndret` timestamp NOT NULL default '0000-00-00 00:00:00',
`BildeAlbumErPrivat` binary(1) NOT NULL,
`Brukernavn` varchar(50) NOT NULL,
PRIMARY KEY (`BildeAlbumID`)
)
-- Linking table links to BildeID and BildeAlbumID
CREATE TABLE `BildeAlbumBilde` (
`BildeAlbumBildeID` int(11) NOT NULL auto_increment,
`BildeAlbumBildeOpprettet` timestamp NOT NULL default CURRENT_TIMESTAMP
on update CURRENT_TIMESTAMP,
`BildeAlbumID` int(11) NOT NULL,
`BildeID` int(11) NOT NULL,
PRIMARY KEY (`BildeAlbumBildeID`)
)
