Linq to SQL产生错误的SQL?

我正在尝试运行Linq to SQL查询,但在计算查询时,出现以下异常:

System.Data.OleDb.OleDbException was unhandled
  Message=The SELECT statement includes a reserved word or an argument name that is misspelled or missing, or the punctuation is incorrect.
  Source=Microsoft JET Database Engine
  ErrorCode=-2147217900

       at xxx.InventoryPopulator`2.Clear(String barcode) in F:\Projects\C#\xxx\xxx\InventoryPopulator.cs:line 38
       [..etc..]
  InnerException: 

调试器显示我的查询是:

SELECT [t0].[SupplierID] AS [Id], [t0].[SupplierSKU] AS [Sku], [t0].[LocalSKU] AS [LocalSku], [t0].[ManufacturersBarcode] AS [Barcode], [t0].[QuantityAvailable]
FROM [inventorySupplier] AS [t0]
WHERE [t0].[ManufacturersBarcode] = @p0

生成上述内容的Linq查询是:

var items = from item in this.supplierItems
            where item.Barcode == barcode
            select item;

如何修复查询?
