[hibernate-issues] [Hibernate-JIRA] Resolved: (HHH-2019) Provide a way to unset properties, and/or provide a 'none' option for hbm2ddl.auto

Provide a way to unset properties, and/or provide a 'none' option for hbm2ddl.auto ---------------------------------------------------------------------------------- Key: HHH-2019 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2019 Project: Hibernate3 Type: Improvement

Environment: hibernate / annotations / hibernate.properties Reporter: Dave E Martin Priority: Minor

It may occasionally be desirable to programmatically get rid of or override a property value, this is generally allowed for by the .setProperty method, however: Once hbm2ddl.auto is set to something, there is no way to unset it, or set it to a value which would be equivalent to its being unset (or its undocumented). There is no remove or unset, or deleteProperty, and also setting it to null does not work. Due to issues such as HHH-2018, it may be necessary to programmatically 'get rid of' hbm2ddl.auto even if the end user (or some other mechanism) has specified a value for it in an external hibernate.properties file (or other method of setting hibernate properties).
