Question

I have 3 tables and need to select some recoreds,
In 2 table of them I have fileds with same name , and when I try to use Where Expression on these filed I got error message :
If I use TABLENAMe.Columns.COLNAME this error message shows : Ambiguous column name ‘FKLoginID’.
and if I use TableNAme.COLColumn.QualifiedName , it has error near created paramter “@[dbo].[Tbl_PersonalInformation].[FKLoginID]0”

How can I query on these tables?
Thanks

 SqlQuery q = new Select().From(Tables.TblStockbrokerBroadDirector)
               .InnerJoin(TblPersonalInformation.PersonalInfoIDColumn, TblStockbrokerBroadDirector.FKPersonalInfoIDColumn)
               .InnerJoin(TblCompanyInformation.BizInfoIDColumn, TblStockbrokerBroadDirector.FKBizInfoIDColumn)
               .Where(TblPersonalInformation.FKLoginIDColumn.QualifiedName).IsEqualTo(User.Identity.Name);
