nhibernate HQL從兩個或多個表中選擇

Question

我一直在嘗試使用HQL獲得兩個類的結果。它適用於一張桌子，但不適用於兩張桌子。

下面兩個實體;

public class A_CUSTOMER 
    { 
     public virtual string CUSTOMER_NO { get; set; } 
     public virtual string ADDRESS_LINE { get; set; } 

     public virtual IList<A_ACCOUNT> ACCOUNTS { get; set; } 
    } 

public class A_ACCOUNT 
    { 
     public virtual string AC_NO { get; set; } 
     public virtual string CUST_NO { get; set; } 
     public virtual string CCY { get; set; } 
     public virtual string AVL_BAL { get; set; } 


     public virtual A_CUSTOMER CUSTOMER { get; set; } 

    } 

以下類別的映射;

public class A_CUSTOMERMap:ClassMap<A_CUSTOMER> 
    { 
     public A_CUSTOMERMap() 
     { 
      Id(x => x.CUSTOMER_NO); 
      Map(x => x.ADDRESS_LINE); 

      HasMany(x => x.ACCOUNTS).KeyColumns.Add("CUST_NO"); 
     } 
    } 


public class A_CUST_ACCOUNTMap:ClassMap<A_CUST_ACCOUNT> 
    { 
     public A_CUST_ACCOUNTMap() 
     { 
      Id(x => x.AC_NO); 
       Map(x=>x.CUST_NO); 
       Map(x => x.AVL_BAL); 
       Map(x => x.CCY); 
       References(x => x.CUSTOMER,"CUST_NO"); 

     } 
    } 

現在，我有這樣的代碼在我的控制器：

string myString = "1001,1002,1003,1004,1005"; 
var indNumbers = myString.Split(','); 
string qry = @"select h.AC_NO,h.BRANCH_CODE,h.CUST_NO,h.CCY,h.AVL_BAL ,g.ADDRESS_LINE"+ 
       "from A_ACCOUNT as h,A_CUSTOMER g "+ 
       "where h.CUST_NO=g.CUSTOMER_NO AND h.AC_NO IN (:list)"; 
       ; 
res = session.CreateQuery(qry) 
     .SetParameterList("list", indNumbers) 
     .List(); 

我也曾嘗試不同的查詢字符串：

string qry = @"select h.AC_NO,h.BRANCH_CODE,h.CUST_NO,h.CCY,h.AVL_BAL ,g.ADDRESS_LINE"+ 
       "from A_ACCOUNT as h left join A_CUSTOMER g on "+ 
       "h.CUST_NO=g.CUSTOMER_NO"+ 
       "where h.AC_NO IN (:list)"; 

下面的錯誤遇到，任何幫助將是非常感激。

Answer 1

你字ADDRESS_LINE之後，第二行之前from

string qry = @"select h.AC_NO,h.BRANCH_CODE,h.CUST_NO,h.CCY,h.AVL_BAL ,g.ADDRESS_LINE"+ 
        "from A_ACCOUNT as h,A_CUSTOMER g "+ 
        "where h.CUST_NO=g.CUSTOMER_NO AND h.AC_NO IN (:list)"; 

一種方法缺少空格rerite這是下降行情中出現的所有： - " + "例如我的樣品中

var qry = @"select h.AC_NO,h.BRANCH_CODE,h.CUST_NO,h.CCY,h.AVL_BAL ,g.ADDRESS_LINE 
          from A_ACCOUNT as h,A_CUSTOMER g 
          where h.CUST_NO=g.CUSTOMER_NO AND h.AC_NO IN (:list)"; 

通知我只有一個啓動"（報價）和結束"。

Answer 2

Rippo是對的間距和報價，另外我發現我仍然參照HQL而不是別名參考名稱

我從 改變了類名「A_ACCOUNT as h left join A_CUSTOMER g on」 到 「from A_ACCOUNT as h left join h.CUSTOMER g on」

應該已經

string qry = @"select h.AC_NO,h.BRANCH_CODE,h.CUST_NO,h.CCY,h.AVL_BAL ,g.ADDRESS_LINE"+ 
       "from A_ACCOUNT as h left join h.CUSTOMER g on "+ 
       "h.CUST_NO=g.CUSTOMER_NO"+ 
       "where h.AC_NO IN (:list)";
