我有以下sql,我想将其转换为linq
SELECT Contrato.finca, SUM(Pago.Importe_subtotal)
FROM Pago, Contrato
WHERE Pago.Contrato = Contrato.ID AND Pago.pagado = 1
GROUP BY Contrato.finca
ORDER BY 2 DESC
GO
我现在在linq中有以下内容,但是group by不起作用。
var x = from contrato in ctx.Contratos
join pago in ctx.Pagos
on contrato.ID equals pago.Contrato
where pago.pagado == true
group contrato by contrato.finca
select contrato.Finca1;
答案 0 :(得分:3)
认为这应该有效:
ctx.Pagos.Where(m=>m.pagado==true).GroupBy(m=>m.Contrato.finca)
.Select(m=> new { Id= m.Key, Val= m.Sum(n => n.Importe_subtotal)})
答案 1 :(得分:2)
尝试
var x = from contrato in ctx.Contratos
join pago in ctx.Pagos
on contrato.ID equals pago.Contrato
where pago.pagado == true
group new {contrato, pago} by contrato.finca into g
select new {
key = g.Key,
sum = g.Sum(p => p.pago.Importe_subtotal)
};
