As you can see, we want to insert our row into the table called mytable. We want to insert three values in three separate columns (id, created date, contents). Furthermore, you should note that you can use the header values and (part of) the payload as dynamic input for those values. The notation as depicted above is paramount in making this work.

	79	+* These examples cover the basic SQL operations: INSERT (Create), SELECT (Read), UPDATE (Update), and DELETE (Delete).
	80	+* SQL queries allow you to perform essential CRUD operations to manage data in a database.
	81	+* You can use dynamic values in SQL queries through SpEL expressions, making your queries more adaptable and flexible.
	82	+* While SQL is commonly used, other databases may require different query languages or syntax for similar operations.
	83	+* Always ensure conditions (like WHERE clauses) are applied to avoid unintentional modifications or deletions of data.
