In Oracle 23ai we can do the same thing using a simple CASE statement or expression using dangling predicates. A dangling predicate is an expression with its left operand missing. This example uses a simple CASE statement with dangling predicates to achieve the same result.

I look for a working example where I can use mutliple when case statment wihch check to verify if a specific text is contained: e.g. SELECT. ID, NAME, (SELECT.
