Setting up a promise in Node Js - node.js

Question

I am having trouble setting up my promise in my code. This is what I have implemented right now:
let promise = new Promise(function(resolve, reject){
ATVStatement();
let isdone = true;
if(isdone){
resolve();
}else{
reject();
}
})
promise.then(CustomMessage());
The problem I am getting is that the I pretty sure that the promise is not working. If anyone could spot the error that I am doing I would greatly appreciate it.
EDIT
Here is code for the the two functions being used:
function ATVStatement() {
request = new Request("select distinct(\"Product Name\") from SPA_Data_Feeds where \"Strategic Priority\" = 'Accelerate to Value (LD)'",
function(err, rowCount, rows)
{
console.log(rowCount + ' row(s) returned');
}
);
//var result = "";
var count = 0
request.on('row', function(columns) {
columns.forEach(function(column) {
console.log("%s\t", column.value);
result+= column.value + "\t\n"; //result is a global variable
count++;
});
});
connection.execSql(request);
}
function CustomMessage(){
console.log('here')
var customMessage = new builder.Message(session)
.text("### Here is a list of the ATV Compounds: \n" + "> %s ", result)
.textFormat("markdown")
.speak("Here is what I found for \'%s\'.", session.message.text)
.textLocale("en-us");
session.send(customMessage); }

Ok, so now we understand the code a little better (thanks for updating), we need to modify the ATVStatement to return a promise and resolve it when the query is complete.
We change the code above to:
let atvPromise = ATVStatement();
atvPromise.then ((result) => {
CustomMessage();
}).catch ( (err) => {
console.log('An error occurred: ' + err);
});
function ATVStatement() {
return new Promise(function(resolve, reject) {
request = new Request("select distinct(\"Product Name\") from SPA_Data_Feeds where \"Strategic Priority\" = 'Accelerate to Value (LD)'",
function(err, rowCount, rows)
{
console.log(rowCount + ' row(s) returned');
if (err) {
reject(err);
} else {
resolve(rows);
}
}
);
var count = 0
request.on('row', function(columns) {
columns.forEach(function(column) {
console.log("%s\t", column.value);
result+= column.value + "\t\n"; //result is a global variable
count++;
});
});
connection.execSql(request);
});
}
You see, ATVStatement was actually asynchronous.
