DbGenerator destroys auto pk support
------------------------------------
Key: CAY-1037
URL: https://issues.apache.org/cayenne/browse/CAY-1037
Project: Cayenne
Issue Type: Bug
Components: Cayenne Core Library
Affects Versions: 3.0
Reporter: Øyvind Harboe
Assignee: Andrus Adamchik
Priority: Critical
The following code will destroy AUTO_PK_SUPPORT table.
When I add a table, I need to add an entry to AUTO_PK_SUPPORT and since I had
setShouldDropPKSupport(false) below, I thought
that only new entries would be added.
However, it seems that *all* entries are deleted from the auto_pk_suport table!
There are some wicked new DbMerger capabilities in Cayenne that allows me to
easily add fields and tables, but the auto_pk_support needs a similar update
capability.
A merger token for auto_pk_support?
DbGenerator generator = new DbGenerator(adapter, destDataMap);
generator.setShouldCreateFKConstraints(false);
generator.setShouldCreatePKSupport(true);
generator.setShouldCreateTables(false);
generator.setShouldDropPKSupport(false);
// we don't want to drop ALL tables, although it could
have been useful to drop only the Mamut tables.
generator.setShouldDropTables(false);
try
{
generator.runGenerator(dataSource);
} catch (Exception e)
{
throw new RuntimeException(e);
}
The last line in the log below killed my Friday evening ;-)
