The Number property returns a long value that is a unique number that can take one of the ErrorValueEnum values. The number describes the error generated by ADO. If the error was generated by the provider, this property may be set to an unspecific error value.
Number属性的作用是:返回一个用于指示ADO错误的独立数字,其数值为ErrorValueEnum值中的一个。如果技术提供对象[provider]产生了错误,那么该属性可能返回一个不确定的错误值。

The numbers are equivalent to the Windows API HRESULTS values.
该数值与Windows API HRESULTS值相等。
