    Assumption:
    A is an already existing table.

    Create table B
    as select * from A
    where 1=2

    To create an empty table from existing table , we just have to give any false condition in the SELECT query , so that it will fail to fetch the records and create copy of the table only , not copy the data

    CREATE TABLE studentcopy
    AS SELECT * FROM student
    WHERE 2 > 3
