SQLite is case insensitive apart from GLOB and glob. Statement end is ‘;’
sqlite3 my_new_database.db
For databases in separate files.
attach database 'test.db' as 'TEST';
detach database 'TEST';
-- create table $dbname.$tablename ( columnN, datatypeN constraints, );
create table main.test (id int primary key not null, name text not null);
drop table main.test;

autoincrement | only on integers, must be last |
-- insert into $tablename (columns) values (values);
-- insert into $tablename values (values) (values) (values)...;
insert into test (id, name) values (1, "bob"), (2, "bill");
-- delete from $tablename where $conditions;
delete from test where id = 1;
-- DELETE ALL RECORDS:

-- where primary key is autoincrement:

-- Arithmetic: + 0 * / %
-- Comparison: == !=, <, <=, >, >=
-- <> : equality test
-- !<, >! : not greater/lesser
-- and, between exists, in, not in, not, or, is null, is, is not
-- unique
-- || : string concat
-- like, GLOB : compare values using wildcards
-- avg(), sum(), count()
-- select count(*) as "value name" from test;
