bookDuplicating Tables

We can create a duplicate of a table using the following query:

CREATE TABLE table_name AS (SELECT STATEMENT);

The above query creates a new table named table_name and inserts the results of the SELECT STATEMENT into it.

Creating an Exact Copy

CREATE TABLE students_duplicate AS SELECT * FROM students;


This query creates a new table called students_duplicate from the result of the query SELECT * FROM students;.

Creating a Concise Table

We can also create a more concise table by selecting specific columns from the target table:

CREATE TABLE students_basic_info AS SELECT name, age FROM students;


This query creates a new table named students_basic_info containing only the first_name and age columns from the students table.

Key Points

  • The new table (table_name) is created with the structure and data of the SELECT query's result;
  • This method is useful for creating backups, filtered copies, or summary tables.
