OData layer generates incorrect alias names in orderby

When a table has large number of columns, a request like the following http://localhost:8080/odata/VDB.1/objectName generates a query like SELECT col1 as c_1, col2 as c2.....col23 as c_23...col35 as c_35 ..FROM objectName ORDER BY "c_0", "c_1", "c_2", "c_3", "c_2"3, "c_3"5. Here c_0, c_1, c_2, c_3, c_23, c_35 happen to be the primary key columns. As seen in the query, the quotes around the column alias are incorrect for c_23 and c_35 which results into an invalid query.
