Create complex JSON objects - api

Question

Hi I have a question to the azure mobile Service custom API script.
I have a custom script to create a JSON Response.
First step was to get flat objects.
Thsi is my code:
var sql = "SELECT [Project].[id] AS [ID]," +
"[Project].[Name] AS [Name]," +
"FROM [Project]";
request.service.mssql.query(sql, [], {
success: function(results) {
if (results.length === 0) {
response.json(statusCodes.OK, results);
return;
}
var resultSet = [];
results.forEach(function(poi) {
resultSet.push(
{
ID: poi.ID,
Name: poi.Name,
RelatedObjects:
{
[
**???**
]
},
});
})
response.json(statusCodes.OK, resultSet);
}
});
This works very well. Now I want to extend my result objects by some sub objects from a releated table. But not simple singel sub properties (this is easy via join), I want to add collections of sub properties selected from another table.
But I don't know how to get the second query into my code? :(
I think it has to be on "???" marked position.
I want to use this JSON self creating code because my result sets are much more complex as the example shows.
Please help!

Ok I solve it with this messi code...
I'm sure there is a more elegant way to do this but I don't found it yet.
var sql = "SELECT [Project].[ID]" +
",[Project].[Name]" +
"FROM [Project]";
var sql2 = "SELECT [ID]" +
",[UniqueSN]" +
",[Name]" +
"FROM [DataLogger]" +
"WHERE [DataLogger].[ProjectID] = ?";
request.service.mssql.query(sql, [id], {
success: function(results) {
var resultSet = [];
results.forEach(function(poi) {
var loggerResultSet = [];
request.service.mssql.query(sql2, [poi.ID], {
success: function(results2) {
results2.forEach(function(logger) {
loggerResultSet.push(
{
ID: logger.ID,
Name: logger.Name,
UniqueSN: logger.UniqueSN,
});
})
resultSet.push(
{
ID: poi.ID,
Name: poi.Name,
Logger: loggerResultSet,
});
response.json(statusCodes.OK, resultSet);
console.log(JSON.stringify(resultSet));
}
});
})
}
});
