How to generate json from two SQL queries? - sql

Question

Tell me who knows how to make a json response of the desired format from two sql requests.
Base (client groups) #1 clients_groups has id_clients and name columns.
id_clients here are client IDs through whom from the clients database.
name is the name of the section.
Base (List of clients) No. 2 clients has data about users.
How to make json. Example as needed:
`
{
id: '',
text: 'Department №1',
children: [ // Here at the bottom you need to get a list of users by ID from department No. 1
{ id: 'User ID', text: 'Username' },
{ id: 'User ID', text: 'Username' }
]
},
{
id: '',
text: 'Department №2',
children: [ // Here at the bottom you need to get a list of users by ID from department No. 2
{ id: 'User ID', text: 'Username' },
{ id: 'User ID', text: 'Username' }
]
}
`
I tried to link data from an attachment through a loop. Nothing helped.
query("SELECT id, id_clients, name FROM clients_groups", (error, results) => {
console.log(results);
})
[
RowDataPacket { id: 1, id_clients: '2', name: 'Manager' },
RowDataPacket { id: 2, id_clients: '2, 3', name: 'Support' }
]
