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.random_string function

Introduced in SQLPage 0.7.2.

Returns a cryptographically secure random string of the given length.

Example

Generate a random string of 32 characters and use it as a session ID stored in a cookie:

INSERT INTO login_session (session_token, username) VALUES (sqlpage.random_string(32), :username)
RETURNING 
    'cookie' AS component,
    'session_id' AS name,
    session_token AS value;
