Subject [jira] Commented: (OPENJPA-1760) Should deleteTableContents always delete really ALL content?
Date Wed, 11 Aug 2010 20:11:35 GMT


Rick Curtis commented on OPENJPA-1760:

Oli -

Could you try swapping out Postgres for MySql or Derby? This might help us narrow down where
the problem is. I'll point out that as far as I can tell 'deleteTableContents' doesn't clear
out all of my tables when running on MySQL.

> At my usecase not all tables are managed by openjpa so not all of them are listed with
the class-tag inside persistence.xml. I set up openjpa to delete the table contents for developping
with the following property:
> <property name="openjpa.jdbc.SynchronizeMappings" value="buildSchema(SchemaAction='add,deleteTableContents')"/>
> But now all contents are deleted even the one of tables which aren't listed inside persistence.xml.

> Shouldn't openjpa only delete contents from tables which are configured plus the openjpa_sequence_table
rather than deleting all contents from the whole database? Is this a bug or is there a property
which I have to set to get the described behaviour?
