Hello Everyone，

Hello Everyone,

我们的数据来自具有以下结构的应用程序。

We have data coming from an application that has the following structure.

CREATE TABLE [dbo].[PriceQuantity](
	[QUANTITY] [image] NULL
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO

INSERT INTO [PriceQuantity]
VALUES('0xBDC5C000000000000000000000000000')
GO

而且，我正在尝试以下查询，它会抛出错误。如何将图像数据类型转换为数字？

And, I am trying the following query and it is throwing an error. How do I convert an image datatype to numeric?

SELECT [QUANTITY], CONVERT(NUMERIC(8,4), TRY_CAST([QUANTITY] AS varbinary))
  FROM [dbo].[PriceQuantity]

Msg 8115, Level 16, State 6, Line 2
Arithmetic overflow error converting varbinary to data type numeric.

谢谢！
