[jira] [Created] (METAMODEL-1111) Empty string treatment in Oracle

Jakub Horcicka created METAMODEL-1111:
-----------------------------------------

             Summary: Empty string treatment in Oracle
                 Key: METAMODEL-1111
                 URL: https://issues.apache.org/jira/browse/METAMODEL-1111
             Project: Apache MetaModel
          Issue Type: Bug
            Reporter: Jakub Horcicka


See https://github.com/datacleaner/DataCleaner/issues/1424

In Oracle empty string is considered as null. That's why some SQL constructs do not work as expected after MM SQL optimization is made. 

There is a problem when using NullCheckFilter and only its NOT_NULL branch together with Oracle datastore. This is related to the '' = null problem.
