SubSonic Inner join Sélectionnez le problème

J'ai 3 tables et je dois sélectionner quelques recoreds, Dans 2 table d'entre eux j'ai des fichiers avec le même nom, et quand j'essaie d'utiliser Where Expression sur ces fichiers, j'ai un message d'erreur: If J'utilise TABLENAMe.Columns.COLNAME ce message d'erreur montre: Nom de colonne ambigu "FKLoginID". et si je l'utilise TableNAme.COLColumn.QualifiedName, il a créé une erreur près paramter "@ [dbo]. [Tbl_PersonalInformation]. [FKLoginID] 0"SubSonic Inner join Sélectionnez le problème

Comment puis-je interroger sur ces tables? Merci

Avez-vous essayé la requête que j'affichée? –

Adam, je vérifie votre requête, sqlquery requête = DB.Select(). De (Tables.TblStockbrokerBroadDirector) .InnerJoin (Tables.TblPersonalInformation) .InnerJoin (Tables.TblCompanyInformation) .Lorsque (TblPersonalInformation.FKLoginIDColumn) .IsEqualTo (User.Identity.Name); Mais j'ai toujours la référence d'objet non définie sur une instance d'un objet. – Ashian

N'utilisez pas TblPersonalInformation.FKLoginIDColumn, utilisez TblPersonalInformation.Columns.FKLoginID –

Les éléments suivants doivent travailler:

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

Changer

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

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

Lorsque vous appelez .QualifiedName que vous appelez par inadvertance Où (chaîne co lumnName) au lieu de Where (colonne TableColumn).

Vous pouvez vérifier cela en vérifiant la valeur de q.BuildSqlStatement(). C'est très utile pour le débogage.
