---------------------------------------
Hi Rick,
thanks for answering. You're right about the not working "IF EXISTS" in
postgres. I didn't thought about it when I posted my suggested bugfix.
Here is the error log (I hope I removed all jsf follow-up errors from my jsf
test app):
<openjpa-2.0.0-r422266:935683 nonfatal general error>

»openjpa_sequence_table« doesn't exist

The error message "ERROR: Relation »openjpa_sequence_table« doesn't exist"
comes directly from postgres. I get the same one if I try to execute the delete
statement (shown above) inside the postgres sql editor.

> SchemaAction=deleteTableContents throws error if table doesn't exist

> Key: OPENJPA-1698
> URL: https://issues.apache.org/jira/browse/OPENJPA-1698
> Project: OpenJPA
> Issue Type: Bug
> Components: jdbc
> Affects Versions: 2.0.0
> Environment: Win XP, Postgres 8.4, OpenJPA 2.0.0
> Reporter: Oliver Bayer
>
> Hi,
> I want to set up my project during development so that all table contents are
> deleted with the following property in persistence.xml:
> <property name="openjpa.jdbc.SynchronizeMappings"
> value="buildSchema(SchemaAction=add,SchemaAction=deleteTableContents)"/>
> If I start up with an empty database I get the following error:
> org.apache.openjpa.persistence.PersistenceException: ERROR: Relation
> >>openjpa_sequence_table<< doesn't exist.
> This error is raised because of the following sql statement: DELETE FROM
> OPENJPA_SEQUENCE_TABLE.
> My suggested solution would be to modify
> DBDictionary.getDeleteTableContentsSQL so that it only deletes content from a
> table if the table exists.
> DBDictionary: Line 2183
> ---------------------------------
> change: deleteSQL.add("DELETE FROM " +
> toDBName(tables[i].getFullIdentifier()));
> to: deleteSQL.add("DELETE FROM " + toDBName(tables[i].getFullIdentifier()) +
> " IF EXISTS");
> What do you mean: Is this a valid bugfix? I'm looking forward to your
> responses.
