asp.net剃刀

Question

有与（VAR query4）怎么个APS desn't告诉我任何味精任何问题，但它不能将数据插入到表concerne

@{ 
    var userId = Request["UserId"]; 
    var Type = Request["type"]; 
    var db = Database.Open("intranet"); 
    if(Type == "delete") 
    { 

    var query = "UPDATE Personne SET Demande = 'refuser' WHERE UserId = '" + userId + "'"; 
    db.Execute(query); 

    var query2 = "DELETE from DemandeConge where UserId = '" + userId + "'"; 
    db.Execute(query2); 
    } 
    else if(Type == "accepte") 
    { 


     var query = "UPDATE Personne SET Demande = 'accepte' WHERE UserId = '" + userId + "'"; 
     db.Execute(query); 

     var query2 = "DELETE from DemandeConge where UserId = '" + userId + "'"; 
     db.Execute(query2); 


     var query4 = "INSERT INTO CongeAccept(UserId,DateDebut,DateFin,TypeConge) SELECT UserId,DateDebutDemande,DateFinDemande,TypeConge FROM DemandeConge WHERE UserId = '" + userId + "'"; 
     db.Execute(query4); 
    } 
} 

和whene我做出评论这个代码它的工作原理，以及：

/* var query = "UPDATE Personne SET Demande = 'accepte' WHERE UserId = '" + userId + "'"; 
    db.Execute(query); 

    var query2 = "DELETE from DemandeConge where UserId = '" + userId + "'"; 
    db.Execute(query2);*/ 


    var query4 = "INSERT INTO CongeAccept(UserId,DateDebut,DateFin,TypeConge) SELECT UserId,DateDebutDemande,DateFinDemande,TypeConge FROM DemandeConge WHERE UserId = '" + userId + "'"; 
    db.Execute(query4); 
}

您正在删除从DemandeConge涉及到要插入CongeAccept所以当尝试插入查询用户的一切，有没有东西插。更改您的语句和使用参数的顺序：

@{ 
    var userId = Request["UserId"]; 
    var Type = Request["type"]; 
    var db = Database.Open("intranet"); 
    if(Type == "delete") 
    { 

    var query = "UPDATE Personne SET Demande = 'refuser' WHERE UserId = @0"; 
    db.Execute(query, userId); 

    var query2 = "DELETE from DemandeConge where UserId = @0"; 
    db.Execute(query2, userId); 
    } 
    else if(Type == "accepte") 
    { 
     var query = "UPDATE Personne SET Demande = 'accepte' WHERE UserId = @0"; 
     db.Execute(query, userId); 

     var query4 = "INSERT INTO CongeAccept(UserId,DateDebut,DateFin,TypeConge) SELECT UserId,DateDebutDemande,DateFinDemande,TypeConge FROM DemandeConge WHERE UserId = @0"; 
     db.Execute(query4, userId); 

     var query2 = "DELETE from DemandeConge where UserId = @0"; 
     db.Execute(query2, userId); 
    } 
}
