php - Two sub select query inside a where condition in laravel5? -


i want compare 2 select query inside condition of query in laravel5,

the where condition of query in laravel given below,but not wokring.

ie,select invoice (select query1) == (select query2).

 $invoice->orwhere(function($query) {                 $query->where('invoices.status', '=', invoicestatusconstant::sent)                         ->where('invoices.due_date', '<', carbon::today()->todatestring())                         ->where(db::raw('(select round(sum(invoice_items.quantity*invoice_items.rate), 2) invoice_items'), '=',                                 db::raw("(select sum(payments.amount) payments "));             });

how can solve issue?

db::raw won't give value. it's way create expression. if wanna way, should use:

db::select(db::raw("(select sum(payments.amount) payments"))

but give array. so, i'd following:

db::select(db::raw("(select sum(payments.amount) pay payments"))[0]->pay

or easier

db::select("(select sum(payments.amount) pay payments")[0]->pay
