MS Access-查询表达式中缺少运算符

Question

我正在开发针对Access数据库运行的.Net平台应用程序。查询失败，并显示错误：

  

“查询表达式中的语法错误（缺少运算符）   'Repairs.CustomerId = Customer.CustomerId内部加入设备打开   Repairs.DeviceId = Device.DeviceId内部加入RepairType   Repairs.RepairTypeId = RepairType.RepairTypeId'。“

我的查询是：

SELECT Customer.CustomerName, Device.Make, Device.Model, Device.Range, RepairType.RepairType, Repairs.DiscountPercent, RepairPrice.Price / 100 * (100-Repairs.DiscountPercent) As CustomerPrice 
From Repairs
Inner Join Customer On Repairs.CustomerId = Customer.CustomerId
Inner Join Device On Repairs.DeviceId = Device.DeviceId
Inner Join RepairType On Repairs.RepairTypeId = RepairType.RepairTypeId

我尝试将每个字段名称包装在方括号中，但结果相同
