             Summary: How can I modify Edm types in olingo by mapping in Olingo
                 Key: OLINGO-1461
                 URL: https://issues.apache.org/jira/browse/OLINGO-1461
             Project: Olingo
          Issue Type: Question
          Components: odata2-jpa
    Affects Versions: V2 2.0.11
            Reporter: Mahdi Ansari


In MySQL the column that are boolean are modeled via {{bit(1)}} or {{byte(1)}}.

When I am using Olingo/Jpa beside MySQL and generate the entities in the Eclipse, it will assign type {{byte}} to these columns. It means in the metadata we will have something like this:
 
{{<Property Name="Deleted" Type="Edm.Byte" Nullable="false"/>}}

How can I modify the EDM type like the following?
 
{{<Property Name="Deleted" Type="Edm.Boolean" Nullable="false"/>}}

What I want to do is to do this modification with a mapping file, something like what explained [here|https://olingo.apache.org/doc/odata2/tutorials/jparedefinemetadata.html]. _(By this tutorial we can only change the names and not the types!)_

Please note that I make {{eclipselink-orm.xml}} also automatically. I don't want to modify this file but it seems the type can be changed there as it has a line like this:
 
{{<basic name="deleted" attribute-type="byte">}}

However I don't want to modify this file each time while I generate it via Eclipse. Is there anyway that I extend some attributes there and inherent the rests?
