i cant reload my dumped data if the table definition changed. maybe i
have renamed a column or something like this. how should my dumped
data know this? So i have to write an update script. But then i have
to write the new schema AND have to write update scripts and still
hve trouble with other developers who should easily get a
corresponding schema for alle the queries they just fetched via cvs
