we add the new column in a table by using alter command as
alter table tablename add columnname datatype constraints


alter table tablename add newLocation varchar(30), oldCityName varchar(20)

To add a column to an existing table, the ALTER TABLE syntax is:

ALTER TABLE table_name
 ADD column_name column-definition;

For example:

ALTER TABLE employee
 ADD employee_name  varchar(50);

This will add a column called employee_name to the Employee table.
