INSERT SELECT SQL: Usage Guide

In SQL, the INSERT SELECT statement is used to insert the results of a query into another table. The syntax is as follows:

INSERT INTO table2 (column1, column2, column3, ...)
SELECT column1, column2, column3, ...
FROM table1
WHERE condition;

This statement will insert data selected from table1 into a specified column in table2. The WHERE clause can be used in the SELECT statement to filter the data to be inserted. It is important to ensure that the number of columns and data types match between the two tables to prevent errors.
