What is the purpose of the select insert into statement in MySQL?

In MySQL, the SELECT INTO statement is used to insert query results into a new table. This can be achieved through the following steps:

1. Use the SELECT statement to retrieve the data to be inserted.
2. Specify the target table into which the data will be inserted using the INTO keyword.
3. Use the INSERT INTO SELECT statement to insert the results of a query into the target table.

This feature is typically used to copy part of the data from one table to another, or to store query results in a new table. This method simplifies the process of data migration and copying, and also provides convenience in data analysis and report generation.
