计算列抛出无法更新错误,即使将其标记为已计算

Computed Column throw can't update error even after marking it as Computed

我有一个已标记为已计算的计算列,但它仍然向我抛出 SqlException:

The column "OPPORTUNITY_VALUE" cannot be modified because it is either a computed column or is the result of a UNION operator.

如何摆脱这个错误?

    [DatabaseGenerated(DatabaseGeneratedOption.Computed)]
    public long? OPPORTUNITY_VALUE { get; set; }

原来,这是我公司使用的 dapper.fastcrud 软件包中的一个错误,抱歉。
