@examples[#:eval my-eval
(make-insert/replace-query 'vals '(a b c))]
This query relies on the fact that in SQLite every table contains a @tt{rowid} column by default.
For more information on why/how the query works, see
@ext-link["https://sqlite.org/lang_insert.html"]{the SQLite docs for @tt{INSERT}}.
@defproc[(make-insert-rows-query [table stringish?] [fields (listof stringish?)] [rows (listof
(listof any/c))]) string?]
Returns a SQLite query string for inserting multiple rows.
@examples[#:eval my-eval
(make-insert-rows-query 'people '(id name) '((1 "Alice") (2 "Bob")))]
