How to create hierarchical JSON from API in AngularJs and MySQL - mysql

Question

I am trying to figure out how to output a structured JSON from a query to my API. I have the following 2 tables (MySQL):
**TABLE1:**
uid
name
pptw
**TABLE2**
id
table1_uid
assignment
start_time
end_time
date
comments
And this is the JSON output I am looking for:
$scope.table1 = {
"toplevel":
[
{
"uid": 1,
"name": "john",
"pptw": "ATWF",
"child":
{
"id": 1,
"table1_uid": 1,
"assignment": null,
"start_time": "14:53:00",
"end_time": "15:00:00",
"date": null,
"comments": null
}
},
{
"uid": 22,
"name": "carol",
"pptw": "DWFF",
"child":
{
"id": 2,
"table1_uid": 22,
"assignment": null,
"start_time": "11:00:00",
"end_time": "14:00:00",
"date": null,
"comments": "Completed"
}
}
]
}
I have a promise as follow:
var request = $http({
method: 'post',
url: '.../api/v1/ppp',
headers: {
'Content-Type': 'application/x-www-form-urlencoded'
},
params: {
//record_uid: record_uid,
}
})
.success(function (data, status, headers, config) {
deferred.resolve(data);
})
.error(function (data, status) {
deferred.reject();
});
return deferred.promise;
And on the database, I have the following query:
SELECT tb1.uid
tb1.name
tb1.pptw,
tb2.id,
tb2.table1_uid,
tb2.assignment,
tb2.start_time,
tb2.end_time,
tb2.date,
tb2.comments
FROM
table1 tb1, table2 tb2
WHERE
tb1.uid = tb2.table1_uid
I would appreciate any ideas on how to achieve this, thanks a lot.

This is the solution to my questions, I managed to figure out how to do it. I hope it helps someone else trying to do the same thing as I did.
Here is how to create the hierarchical JSON:
var results_tree_header = [];
var results_tree = [];
if (result.rows.length > 0) {
for (var i = 0; i < result.rows.length; i++) {
results_tree.push({
"uid": result.rows.item(i).uid,
"name": result.rows.item(i).name,
"pptw": result.rows.item(i).pptw,
"child":
{
"id": result.rows.item(i).id,
"table1_uid": result.rows.item(i).table1_uid,
"assignment": result.rows.item(i).assignment,
"start_time": result.rows.item(i).start_time,
"end_time": result.rows.item(i).end_time,
"date": result.rows.item(i).date,
"comments": result.rows.item(i).comments
}
});
results_tree_header = { toplevel: results_tree };
}
}
