Question

I am currently using mongoose, with this model instructions in model called tickets

Fromticket, Number default 0 Toticket, number, default 0

Let say I have these rows:

{fromticket:1 , toticket:3000},
fromticket:3001 , toticket:29000}

,

how can I find the row that contains for example the ticket is 20000? Or 3001? ( would be row number 2 in the example)

Tickets.find( row where owner is ticket 2000)

Answer 1

Each term in a query is implicitly ANDed, so you can query for the document where fromticket <= 20000 and toticket >= 20000 using:

var ticket = 20000;
Tickets.findOne({
    fromticket: {$lte: ticket},
    toticket: {$gte: ticket}
}, (err, ticket) => {...});
