INSERT INTO <TABLE_NAME> (<column1>,<column2>,<column3>,...) 
VALUES (<value1>,<value2>,<value3>,...);

SELECT * FROM table1
WHERE condition;

SELECT * INTO nome_da_tabela_que_estao_a_mexer_BKP
	FROM nome_da_tabela_que_estao_a_mexer

Example 5: insert into select sql

Let’s assume that, we have our employee table.
We have to copy this data
into another table. For this purpose,
we can use the INSERT INTO SELECT
operator. Before we go ahead and do that,
we would have to create another
table that would have the same structure
as the given table.
• First create the second table with
the same table structure with copied one.
• Then use the syntax:
Let’s say employee_duplicate is New table
employee is First table that we want to copy it into new table

INSERT INTO employee_duplicate SELECT * FROM employee;
