    <p>Currently I'm developing a webapp which uses Oracle as a database. I've already been informed that my webapp has to work also on Sybase ASE. My Oracle database uses sequences to generate IDs and I mapped my domain classes to use those sequences. As far I know Sybase ASE doesn't have sequences but identities. And here is my problem. What to do with code/configuration to work with Oracle and Sybase. Some "conditional mapping" of ID for each domain would do. </p> <p>I just don't want to comment/uncomment lines in mappings every time when I'm building webapp for other database than already mapped. <strong>Have anybody any idea what to do?</strong></p> <p>There is another danger: another differences between Oracle and Sybase which have influence on mapping (I don't generate database structure using <code>dbCreate = "create"</code>) . At this point I don't see anything. <strong>Any experiences?</strong></p> <hr> <p><strong>EDIT:</strong> It turned out that it's not possible make one mapping for both databases. My Oracle structure uses quotes in column and table names. And quotes are not allowed in Sybase ASE. My (not nice and pretty) solution is changing (comment/uncomment) mapping when building webapp on some particular platform.</p> <p>Btw I'm huge fan of Grails and this mapping thing seems to be a drawback. If I was using "pure" Hibernate I'd have two mappings in xml files and I'd change them depending on an underlying database. But Grails doesn't give me possibility to have two mappings.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
