> SQLite doesn't do stored procedures

Link: https://www.sqlite.org/gencol.html

Example:

CREATE TABLE t1(

   a INTEGER PRIMARY KEY,

   b INT,

   c TEXT,

   d INT GENERATED ALWAYS AS (a*abs(b)) VIRTUAL,

   e TEXT GENERATED ALWAYS AS (substr(c,b,b+1)) STORED

);

Note how you can call functions in the columns. Thats one feature which a hardened sqlite for less trusted documents would need to not have.
