Copy the value from the “profession “ column

Redesign the my_contacts table by moving the “profession” column out of my_contacts table and create a table “professions”, which should have two columns: “ id “, “ profession “.

•Copy the value from the “profession “ column in the my_contacts table into the new table.

•Add a new column “ profession_id “ in the my_contacts table and update it based on the value of the “profession “ column.

•Drop the ”profession” column in the my_contacts table.

•Make some queries using INNER JOIN and subquery:

•Get “first_name”, “last_name”, “profession” information for which ”last_name” is “Hardy”.

•Get all the columns from my_contacts table for which profession is 'Web Designer’.
