Use SQL REPLACE in View Criteria

Question

Hi,
I'm using JDev 11.2.3.0.
I have created a View Criteria to restrict on email address and need to strip off the '@domain.com' part of the bind variable. In SQL I would just use REPLACE to do this, but cannot find a way to add that keyword in the View Criteria dialogue.
Do I need to modify the Bind variable using EL? If so, how do I refer to the bind variable itself in the bind variable expression?
Many thanks.

You can't just use EL without permanently changing the input of the user (e.g. using a converter to strip away the '@domain.com' part).
You need to overwrite the prepareRowSetForQuery method in the VO you are using to make the query. In this method you can alter the bind variable before the query executes.
//In view object implementation
public void prepareRowSetForQuery(ViewRowSetImpl vrs) {
  //Set the value for bind variable ':bindVarDeptId' only for default row set
  if(vrs.isDefaultRowSet()){
    vrs.setNamedWhereClauseParam(  "bindVarDeptId", getUserDeptId());
   super.prepareRowSetForQuery(vrs);
}Timo
