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
