It should be noted that a where clause can have additional nesting. Hence, we need to have a recursive mechanism to traverse through all the depths and collect the table references. It is important to note that the where clause also contains a from clause. So we need to include that functionality as well. Oh yes! The where clause can also contain a select clause.
The method to identify the tables mentioned in the where clause is given below.
