asp.net剃刀

Question

有與（VAR query4）怎麼個APS desn't告訴我任何味精任何問題，但它不能將數據插入到表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我做出評論這個代碼它的工作原理，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); 
}

您正在刪除從DemandeConge涉及到要插入CongeAccept所以當嘗試插入查詢用戶的一切，有沒有東西插。更改您的語句和使用參數的順序：

@{ 
    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); 
    } 
}
