tiny_sqlite is a comparatively thin wrapper for the SQLite database library. It differs from the standard library module std/db_sqlite in several ways:

• tiny_sqlite represents database values with a typesafe case object called DbValue instead of treating every value as a string, which among other things means that SQLite NULL values can be properly supported.

• tiny_sqlite is not designed as a generic database API, only SQLite will ever be supported. The database modules in the standard library are built with replaceability in mind so that the code might work with several different database engines just by replacing an import. This is not the case for tiny_sqlite.

• tiny_sqlite is safe. Unlike std/db_sqlite the raw SQLite handles are not used directly to prevent use-after-free bugs triggering undefined behavior.

tiny_sqlite is available on Nimble:

nimble install tiny_sqlite

import tiny_sqlite, std / options

let db = openDatabase(":memory:")
db.execScript("""
CREATE TABLE Person(
    name TEXT,
    age INTEGER
);

INSERT INTO
    Person(name, age)
VALUES
    ("John Doe", 47);
""")

db.exec("INSERT INTO Person VALUES(?, ?)", "Jane Doe", nil)

for row in db.iterate("SELECT name, age FROM Person"):
    let (name, age) = row.unpack((string, Option[int]))
    echo name, " ", age

# Output:
# John Doe Some(47)
# Jane Doe None[int]
