SubSonic內部加入選擇問題

我有3個表，需要選擇一些recoreds，在他們的2表中我有同名的fileds，並且當我嘗試使用Where表達式在這些提交我得到錯誤信息：如果我使用TABLENAMe.Columns.COLNAME這個錯誤消息顯示：不明確的列名'FKLoginID'。如果我使用TableNAme.COLColumn.QualifiedName，它在創建的參數「@ [dbo]。[Tbl_PersonalInformation]。[FKLoginID] 0」附近有錯誤「SubSonic內部加入選擇問題

如何查詢這些表？感謝

您是否嘗試過我張貼的查詢？ – 2009-05-28 14:14:58

下面應該工作：

SqlQuery query = DB.Select().From(Tables.TblStockbrokerBroadDirector) 
    .InnerJoin(TblPersonalInformation) 
    .InnerJoin(TblCompanyInformation) 
    .Where(TblPersonalInformation.Columns.FKLoginIDColumn).IsEqualTo(User.Identity.Name);

變化

.Where(TblPersonalInformation.FKLoginIDColumn.QualifiedName).IsEqualTo(User.Identity.Name);

到

.Where(TblPersonalInformation.FKLoginIDColumn).IsEqualTo(User.Identity.Name);

當你調用.QualifiedName你無意中調用在其中（字符串合作lumnName）而不是Where（TableColumn列）。

您可以通過檢查q.BuildSqlStatement（）的值來驗證這一點。這對調試非常有用。
