SQL statements with subqueries

Copying data from one table to another - 1

There is a students table below with a few columns. The table studentsClone has the exact same number and type of columns as students. The table studentsMarks has only id, name and marks columns that are same as students, and a few extra columns. Neither studentsClone, nor studentsMarks have any records.

Write a set of SQL statements to:

  1. Copy all the records for all columns in the same order, from students to studentsClone
  2. Copy all the records for the columns id, name and marks from students to studentsMarks. Leave the values for extra columns in studentsMarks as NULL.
