SQLite does NOT have a built-in array data type. You can store a serialized representation of your array in a TEXT column. This could be a comma-separated list, a JSON array, or any other format that suits your needs.
comma-separated list
CREATE TABLE MyTable (
id INTEGER PRIMARY KEY,
my_array TEXT
);
INSERT INTO MyTable (my_array) VALUES ('element1,element2,element3');
JSON array
CREATE TABLE MyTable (
id INTEGER PRIMARY KEY,
my_json_array TEXT
);
INSERT INTO MyTable (my_json_array) VALUES ('["element1", "element2", "element3"]');
