C# SQL代码在Access中工作，但不在Visual Studio中工作？

我有以下SQL代码，它是使用Microsoft Access中的查询设计视图生成的

SELECT tblLoan.BorrowerID, tblBorrower.BorrowerFirstName, tblBorrower.BorrowerLastName, tblBorrower.Address1, tblBorrower.Address2, tblBorrower.City, tblBorrower.ContactNumber, tblBorrower.DateOfRegistration, tblBorrower.Gender, tblBorrower.Email, tblLoan.LoanID, tblLoan.ReceivedBy, tblLoan.Fine, tblLoan.CostPerDay, tblLoan.OverdueDays, tblLoan.OverdueFine, tblLoan.AdminID, tblBookLoan.BookID, tblBookLoan.DateOut, tblBookLoan.DateDueBack, tblBookLoan.ReturnDate, tblBook.Title, tblBook.Author, tblBook.ISBN, tblBook.PublicationYear
FROM tblType INNER JOIN (tblBookType INNER JOIN (tblBookCategory INNER JOIN ((tblBorrower INNER JOIN tblLoan ON tblBorrower.[BorrowerID] = tblLoan.[BorrowerID]) INNER JOIN (tblBook INNER JOIN tblBookLoan ON tblBook.[BookID] = tblBookLoan.[BookID]) ON tblLoan.[LoanID] = tblBookLoan.[LoanID]) ON tblBookCategory.BookCategoryID = tblBook.BookCategoryID) ON tblBookType.BookTypeID = tblBook.BookTypeID) ON tblType.TypeID = tblBorrower.TypeID
WHERE (((tblBookLoan.DateDueBack)<Date()));

选择TBLLOOR.BROWERID、tblBorrower.BROWERFIRSTNAME、tblBorrower.BROWERLASTNAME、tblBorrower.Address1、tblBorrower.Address2、tblBorrower.City、tblBorrower.ContactNumber、tblBorrower.DATEOFF、tblBorrower.Gender、tblBorrower.Email、TBLLOANID、tblLoan.ReceivedBy、TBLLOOAN.Fine、tblLoan，tblLoan.OverdueFine，tblLoan.AdminID，tblBookLoan.BookID，tblBookLoan.DateOut，tblBookLoan.DateDueBack，tblBookLoan.ReturnDate，tblBook.Title，tblBook.Author，tblBook.ISBN，tblBook.PublicationYear
从tblType内部联接（tblBookType内部联接（tblBookCategory内部联接）（TBLBorLower内部联接tblLoan ON TBLBorLower。[借阅者ID]=tblLoan。[借阅者ID]）内部联接在tblBookCategory.BookCategoryID=tblBook.BookCategoryID）在tblBookType.BookTypeID=tblBook.BookTypeID）上
其中（（tblBookLoan.DateDueBack）在SQL server中，检索当前日期时间的函数是
GetDate（）
