SQL database settings: disable quoted column names for certain database types #81

Open Sat-Ing opened 2 weeks ago

Sat-Ing commented 2 weeks ago

With #19 , there was a change which quotes all database related names. There is a setting which can disable this feature: -Dorg.eclipse.net4j.db.DISABLE_QUOTED_NAMES=true

We need to use this setting for a MariaDB 10.2.6. I assume that this also applies for MySQL. Would it be possible to disable quoting by default for the MySQL adapter? New users would appreciate this for sure.

I guess that would be possible (not checked, yet). But before investigating further I'd like to understand why you need to disable it. Can you explain please?

Without this setting, the CDO repository cannot be initialized in my case. This is with CDO version 2024-06 for a freshly created repository:
