SubSonic Inner join問題を選択

私は3つのテーブルを持っており、いくつかのrecoredを選択する必要がありますそれらの2つのテーブルで、私は同じ名前のfiledsを持っており、これらのフィールドでWhere Expressionを使用しようとするとエラーメッセージが表示されます： If私はこのエラーメッセージが示すTABLENAMe.Columns.COLNAMEを使用します：あいまいな列名 'FKLoginID'。 TableNAme.COLColumn.QualifiedNameを使用すると、作成されたパラメータ "@ [dbo]。[Tbl_PersonalInformation]。[FKLoginID] 0"のエラーが発生します。SubSonic Inner join問題を選択

これらのテーブルを照会する方法はありますか？おかげで、次の動作するはず

SqlQuery q = new Select().From(Tables.TblStockbrokerBroadDirector) 
       .InnerJoin(TblPersonalInformation.PersonalInfoIDColumn, TblStockbrokerBroadDirector.FKPersonalInfoIDColumn)

あなたは、私が投稿クエリを試してみました。このエラーメッセージが表示されましたか？ –

アダムは、私はあなたのクエリを確認し、のSQLQueryクエリ= DB.Select（）。（Tables.TblStockbrokerBroadDirector） .InnerJoin（Tables.TblPersonalInformation） .InnerJoin（Tables.TblCompanyInformation） .Where（TblPersonalInformation.FKLoginIDColumn）から.IsEqualTo （User.Identity.Name）; しかし、私はまだオブジェクトのインスタンスに設定されていないオブジェクト参照を得ました。 – Ashian

TblPersonalInformation.FKLoginIDColumnを使用しないで、TblPersonalInformation.Columns.FKLoginIDを使用します。 –

：あなたは.QualifiedNameを呼び出すと

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

変更

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

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

には、あなたが誤っどこ（文字列のコ呼んでいますwhere（TableColumn列）の代わりにlumnName）を使用します。

これは、q.BuildSqlStatement（）の値を確認することで確認できます。これはデバッグに非常に便利です。
