VARCHAR is just text
VARCHAR specifications are accepted by SQLite, but do note that these are just regarded as TEXT.
SQLite does not enforce the length of a VARCHAR. You can declare a VARCHAR(10) and SQLite will be happy to store a 500-million character string there. And it will keep all 500-million characters intact. Your content is never truncated. SQLite understands the column type of “VARCHAR(N)” to be the same as “TEXT”, regardless of the value of N.
