When you use a tag function like `sql` with a template literal, the function receives the static string parts and dynamic values separately. Instead of concatenating them into a raw SQL string, the tag function returns a parameterized query — the SQL string with placeholders and a separate values array — which is then passed to the database driver safely. This pattern is used by the @neondatabase/serverless driver as well as other libraries like Kysely and Postgres.js, and it prevents SQL injection by never directly interpolating user input into the query string. ## Full article daily.dev links to this article rather than hosting it.
