You don't and there is no reason to. This questions is asked way too often, was asked just a few days ago (probably by someone else in your class), yet not one single one of them had ever said why they want to do it. "Because the teacher said so" is not a valid response.

The concept of a Relational Database can be found the the Database Concepts Guide.

Do you want to add columns in existing table??

If so,Do this

alter table
   table_name
add
   (
   column1_name column1_datatype column1_constraint,  
   column2_name column2_datatype column2_constraint,
   column3_name column3_datatype column3_constraint
   );

This won't help the OP. The OP wanted to "add a new column in between a tables existing columns".
