tsql算术溢出仅使用adodb将表达式转换为数据类型int

对于我正在处理的应用程序，我遇到以下错误：

错误“80040e57” 将表达式转换为数据类型int时出现算术溢出错误

执行此查询时：

    SELECT 0 as type_elm

在具有adoDb对象的asp应用程序中执行，wierd认为此查询在SQL Server中执行时没有问题，在执行到SQL Server后，应用程序运行时没有错误，直到我清除SQL Server的缓存。我不理解这个问题。

从ADO而不是SSMS中得到错误的原因是不同的执行计划。一个计划可能在计划的前面使用问题值计算表达式

考虑从以下位置更改类似的表达式：

CAST((-100 * def_ger.id_cld) as bigint) 

到

因此，中间结果和最终结果都是较大的类型。

可能重复的

CAST(-100 * CAST(def_ger.id_cld as bigint))
