Jacques Le Roux commented on OFBIZ-8343:
----------------------------------------
First you need to read
https://cwiki.apache.org/confluence/display/OFBADMIN/Coding+Conventions#CodingConventions-EntityFieldNames
but of course things can change.
Because it does not need any installation and can be embedded we deliver OFBiz
with Derby. Derby has a limitations of 30 chars for column names
https://db.apache.org/derby/docs/10.0/manuals/reference/sqlj268.html#Identifier+length+limitations
If you know a mean to override this situation please share (don't forget the
JDBC driver aspect). Then rests that this would be an important change and
would need a migration service
https://cwiki.apache.org/confluence/display/OFBIZ/Revisions+Requiring+Data+Migration+-+upgrade+ofbiz
Anyway this kind of topic needs to be prior discussed in the dev ML... Else
please close...
