How to avoid 'Unknown' data types when generating code with MyGeneration and Oracle 10?

I am attempting to generate a dOOdads business entity using MyGeneration against an Oracle database table. ( http://www.mygenerationsoftware.com/portal/dOOdads/Overview/tabid/63/Default.aspx )

The class generator appears to have issues detecting the data types. For instance, PHOTOID is VARCHAR2. The class generated contains the following:

    public virtual Unknown PHOTOID
    {
        get
        {
            return base.GetUnknown(ColumnNames.PHOTOID);
        }
        set
        {
            base.SetUnknown(ColumnNames.PHOTOID, value);
        }
    }

In other case, MyGeneration was not able to correctly id the following DATE column.

        public virtual Unknown SYNC_UPLOAD_DT
    {
        get
        {
            return base.GetUnknown(ColumnNames.SYNC_UPLOA开发者_开发百科D_DT);
        }
        set
        {
            base.SetUnknown(ColumnNames.SYNC_UPLOAD_DT, value);
        }
    }

If you know how to resolve this error, I would greatly appreciate your help!

I was able to resolve this issue. I found that I did not specify the 'Database target mapping' settings on the 'Default settings' tab. After making this change, the generated classes were implemented with reasonable data types.
