I'd like your opinion about exporting view of view in xml format.
Aamir Khan prepared a patch [0] that creates an XML export in the way this is handled in SQL export, ie first all tables and views are exported. All views are exported as standin tables with the same structure. Then all views are recreated, first dropping the standin tables, and creating the real views. The reason for this is to make sure that when creating a view that uses another view, it at least exists, thus avoiding an error upon importing it again. Downside of this is that the xml export of the structure schema gets a bit confusing with a <pma:table>, <pma:drop> and <pma:view> tag for every view, as the xml export is intended to be used by custom scripting.
I don't think that XML should be replacement of the SQL, especially I don't see need for <pma:drop>. So it should just describe the data and import should handle such problems. -- Michal Čihař | http://cihar.com | http://phpmyadmin.cz
