open static fun extractDatabaseMetaData(dataSource: DataSource, action: DatabaseMetaDataCallback): Any
Extract database meta data via the given DatabaseMetaDataCallback.
This method will open a connection to the database and retrieve the database metadata. Since this method is called before the exception translation feature is configured for a datasource, this method can not rely on the SQLException translation functionality.
Any exceptions will be wrapped in a MetaDataAccessException. This is a checked exception and any calling code should catch and handle this exception. You can just log the error and hope for the best, but there is probably a more serious error that will reappear when you try to access the database again.

action - callback that will do the actual work
