BC4J: embedding Special SQL in View Objects

Question

While BC4J allows for easier development because developers do not need to embed a lot of SQL in Java codes, I wonder how I could embed special SQLs either into my Java code or in the View Object Wizard. For example, the following SQL statement could not be entered into the View Object Wizard:
select key1, key2, SCORE(10),SCORE(20)
from table1
where contains (attrib1, 'apple', 10) >0 OR
contains (attrib1, 'orange', 20) > 0
Order by NVL(SCORE(10),0), NVL(SCORE(20),0);
How can I embed the above SQL statement properly in a View Object? Or do I have to write SQLJ code outside of a View Object?

Answer 1

As you mentioned BC4J gives the flexibility of using all valid SQL statements.
For you query above, you would have to do the following.
You would need to create caluclated attributes for SCore(10) and score(20)
Select the ViewObject in Navigator and edit it (right mouse button)
Select Attributes Tab
Click on New attribute Score(10) and you can give an alias name for that.
same goes for score(20) also.
Select query tab now
Choose expert mode check box
Paste your query in the text box
and Orderby clause in the orderby textbox
click on the test button to test it
