How to remove inaccessible fields from the query result with Security.stripInaccessible

 Hi,

Here we are going to learn how to remove inaccessible fields from  the query:

Let's take a scenario 

A display table for campaign data must always show the BudgetedCost. The ActualCost must be shown only to users who have permission to read that field.

Code Snippet:

SObjectAccessDecision securityDecision = 

         Security.stripInaccessible(AccessType.READABLE,

                 [SELECT Name, BudgetedCost, ActualCost FROM Campaign];

                 );

    // Construct the output table

    if (securityDecision.getRemovedFields().get('Campaign').contains('ActualCost')) {

        for (Campaign c : securityDecision.getRecords()) {

        //System.debug Output: Name, BudgetedCost

        }

    } else {

        for (Campaign c : securityDecision.getRecords()) {

        //System.debug Output: Name, BudgetedCost, ActualCost

        }

}
