What is 1=2 in sql

This type of command is usually used to copy the structure of one table 
to another. In this case, EMPL_DEMO will have the same column structure 
of employees , except for the keys or constraints. The 1=2 always 
evaluates to False which prevents you from copying any of the rows.
