Preventing caching of select query result in Sqlite using NodeJS - node.js

Question

I am currently writing an API in NodeJS using express that retrieves data from a Sqlite database. The table containing the data, called DATA, to be retrieved has three columns:
ID - Integer
VALUE - Real
DATERECORDED - Integer
The data from the last five months is to be returned, and to do this, I am using the following query:
SELECT ID, VALUE FROM DATA WHERE DATERECORDED BEWTEEN date('now') AND date('now', '-5 months')
I recently removed several records from the database and entered new records. However, when I make a GET request to my API, I still get back the data that would've been returned when the old records were contained in the database. I even deleted all of the records in the database, but the old results are still being returned. Is there anyway that I can prevent this caching ?
I have also tried setting the cache_size to 0. The query is being used in the following code:
app.get('/get-data', function(req, res) {
console.log('Sending performance');
var stmnt = // query comes here
if(!exists) {
res.send({});
} else {
var db = new sqlite3.Database(db_path);
db.all(stmnt, function(err, rows) {
if(err) {
res.send({});
}
if(rows) {
var docs = {};
var by_id = _.groupBy(rows, function(row) {
return row.ID;
});
for(var key in by_id) {
if(by_isp.hasOwnProperty(key)) {
docs[key] = _.map(by_id[key], 'VALUE');
}
}
res.send(docs);
} else {
res.send({});
}
});
db.close();
}});
