Getting real sql code

Question

Hi to All
I want to know if is possible get the real string sql of an operation using some class of toplink?
For example:
I have an expression "Expression ex = new ExpressionBuilder().get("CadTitular").get("titId").equal(5)"
This is equals the following sql command "select * from CadTitular where tit_id = 5"
I need get the sql value to leave an operation toplink for example:
ExpressionBuilder emp = new ExpressionBuilder();
Expression firstNameExpression = new ExpressionBuilder();
firstNameExpression = emp.get("fName").like("%a%").and(new ExpressionBuilder().get("empId").greaterThan(10));
ReadObjectQuery query = new ReadObjectQuery();
query.setReferenceClass(Employee.class);
query.setSelectionCriteria(firstNameExpression);
//********************GETTING THE SQL CODE***********************
DatabaseRow row = new DatabaseRow();
query.prepareCall(session, row);
String sql = query.getTranslatedSQLString(session, row);
System.out.println("STRING VALUE: " + sql);
Employee employee = (Employee)session.executeQuery(query);
This code print "SELECT EMP_ID, F_NAME, GENDER, END_DATE, L_NAME, VERSION, START_DATE, END_TIME, START_TIME, ADDR_ID, MANAGER_ID FROM EMPLOYEE WHERE ((F_NAME LIKE '%a%') AND (EMP_ID > 10))"
But when I use to the following objects : UpdateObjectQuery, InsertObjectQuery, ReadAllQuery, WriteObjectQuery, The code above it does not function. How I can do this?
How I can do using the UnitOfWork?
Thank

If you want to copy your LOG output from toplink from these objects (UpdateObjectQuery, InsertObjectQuery, ReadAllQuery, WriteObjectQuery) and have it run perfectly in a SQL editor, you need to turn on NativeSQL. Otherwise, things like dates will need to be reformatted by hand. Also, you will need to turn binding off. Both of these options (NativeSQL, binding) can be turned on/off via sessions.xml and from JAVA.
