Define WHERE Clause on dynamic ViewObject created on the fly

We all know there are different ways to define WHERE clause on a viewObject at runtime and previously I have posted about it
Check -

ADF Basics: Apply and Change WHERE Clause of ViewObject at runtime programmatically
ADF Baiscs: Define and remove named bind variable in viewObject at runtime programmatically
Setting view object bind variable (Override bindParametersForCollection, prepareRowSetForQuery, executeQueryForCollection )

This post is about defining WHERE Clause on dynamic viewObject created at run time using SQL query

So for this created a dummy view object using dual

SELECT*FROM DUAL


Now remove this dummy viewObject and create new ViewObject with same name using query

//Get dummy viewObject
ViewObject dynVo =this.getdynamic1();
//Remove viewObject from Application Module
dynVo.remove();
//Creates a read-only View Object, given a query statement and a name for the View Object.
this.createViewObjectFromQueryStmt("dynamic1","SELECT * FROM DEPARTMENTS");

There is no difference in syntax of setWhereClause method but here we pass JDBC Positional bind variable using "?"symbol



//Apply desired WHERE Clause and declare bind variable
dynVo.setWhereClause("DEPARTMENT_NAME=?");

//Pass Bind Variable value using index
dynVo.setWhereClauseParam(0,"Finance");

// Execute ViewObject to finally apply where clause
dynVo.executeQuery();

This is how we can apply WHERE clause on dynamic viewObjects
Cheers :) Happy Learning
