Question

我为SQL Server制作了这段代码，以选择2017年第一学期骑手“AsdoVolante”首次出现的次数。但它不起作用。可能有什么不对？

SELECT P.Data, Nm.Nome, epp.PosicaoFinal
FROM Prova P, Piloto Nm, EquipaParticipaProva epp
WHERE epp.PosicaoFinal = (SELECT PosicaoFinal FROM EquipaParticipaProva where PosicaoFinal = 1)
HAVING Nm.Nome ='AsdoVolante' AND P.Data BETWEEN '2017-01-01' AND '2017-06-30';

在SQL Server中为代码创建的表：

IdPiloto INT NOT NULL,

CREATE TABLE Patrocinador(

CREATE TABLE Prova(

Answer 1

试试这个

SELECT P.Data, Nm.Nome, epp.PosicaoFinal
FROM Prova P, Piloto Nm, EquipaParticipaProva epp
WHERE epp.PosicaoFinal **IN** (SELECT PosicaoFinal FROM EquipaParticipaProva where PosicaoFinal = 1)
HAVING Nm.Nome ='AsdoVolante' AND P.Data BETWEEN '2017-01-01' AND '2017-06-30';
