In part one, showed how to implement a SQL IN clause in ADF. Now I show how to use this technique in a ViewCriteria or directly in a query of a view object.
We have to solve a couple of problems before we can really use the technique from part one in a ViewCriteria. As you know, when using a ViewCriteria, you select an operator which in turn is translated into SQL code. So, we have to find a way to create a new operator which will then be used to create the needed SQL code.
The technique to do this comes from an older post. Please look at Extending ViewCriteria to use SQL CONTAINS where I showed the basics on how to do this. The older post was designed for JDeveloper 11.1.2.1.0. Using the current JDeveloper version 12.2.1.3 give some ways for improvement of the earlier code. Read the complete article here.
