mysql - 如何使mysql中的查询字段成为INT

Question

我正在做这个查询：

select tblagenda.ValorServicio, ((tblcopago.bonos + tblcopago.copago) * tblagenda.ValorServicio / grupo.Total) as Copago, grupo.Total
    from tblcopago
    inner join tblagenda on (tblagenda.CodigoOrden=tblcopago.CodigoOrden)
    join (select sum(ValorServicio) as Total, CodigoOrden from tblagenda group by CodigoOrden) grupo on grupo.CodigoOrden = tblagenda.CodigoOrden

我希望 Copago 字段为 INT

Answer 1

如果要对结果进行四舍五入：

 SELECT ROUND((tblcopago.bonos + tblcopago.copago) * tblagenda.ValorServicio / grupo.Total) as Copago

如果你想把它放在地板上（截断到较低的 int）：

 SELECT FLOOR((tblcopago.bonos + tblcopago.copago) * tblagenda.ValorServicio / grupo.Total) as Copago

...如果你想要上限值（截断 + 1）：

 SELECT CEIL((tblcopago.bonos + tblcopago.copago) * tblagenda.ValorServicio / grupo.Total) as Copago
