SQLPage built-in functions

In addition to normal SQL functions supported by your database, SQLPage provides a few special functions to help you extract data from user requests.

These functions are special, because they are not executed inside your database, but by SQLPage itself before sending the query to your database. Thus, they require all the parameters to be known at the time the query is sent to your database. Function parameters cannot reference columns from the rest of your query.

The sqlpage.hash_password function

Introduced in SQLPage 0.7.2.

Hashes a password using the Argon2 algorithm. The resulting hash can be stored in the database and then used with the authentication component.

Example

SELECT 'form' AS component;
SELECT 'username' AS name;
SELECT 'password' AS name, 'password' AS type;

INSERT INTO users (name, password_hash) VALUES (:username, sqlpage.hash_password(:password));
