The `INSERT INTO` statement is a crucial part of any SQL developer's toolkit. It allows you to add new records (rows) to an existing table. This is essential for populating your database with data. Understanding how to use `INSERT INTO` correctly is vital for maintaining and updating your database. You can insert data into a table in several ways, depending on the amount of data you need to add and the structure of your table. For example, you might insert a single row, or multiple rows at once. You can also insert data from another table or a query result. The `INSERT INTO` statement is a fundamental building block for data manipulation in SQL.
