Get parts and its associated library using API's only

Hello,

I have following SQL

select master.wtpartnumber, lib.NAMECONTAINERINFO, lib.IDA2A2 from wtpartmaster master, wtlibrary lib where master.wtpartnumber not like '%-R'  and master.IDA3CONTAINERREFERENCE = lib.IDA2A2  and lib.NAMECONTAINERINFO not like '%test%'

I want to use this SQL in Windchill API's but I'm unsuccessful so far, here is what I have so far:

        final QuerySpec qs = new QuerySpec();        int lib = qs.addClassList(WTLibrary.class, false);        int mastInt = qs.addClassList(WTPartMaster.class, false);        ClassAttribute ca = new ClassAttribute(WTPartMaster.class, WTPartMaster.NUMBER);               ClassAttribute ca1 = new ClassAttribute(WTLibrary.class, WTLibrary.CONTAINER_ID);        qs.appendSelect(ca, new int[]{0}, false);        qs.appendSelect(ca1, new int[]{1}, false);        qs.appendWhere(new SearchCondition(WTLibrary.class, WTLibrary.NAME, SearchCondition.NOT_LIKE, "%test%"), new int[]{0});        qs.appendJoin(mastInt, WTPartMaster.CONTAINER_ID, lib);               // Below condition through error        //qs.appendAnd();        //qs.appendWhere(new SearchCondition(WTPartMaster.class, WTPartMaster.CONTAINER_ID, SearchCondition.EQUAL, WTLibrary.CONTAINER_ID), new int[]{0});        System.out.println("\n\n" + qs.toString() + "\n\n" + qs.getWhere() + "\n\n");

Can someone help me how to write the above SQL in API's?

Thanks,
