为什么SSRS要求在定义时定义查询参数？

Question

我有以下查询，它在SQL中运行良好。但是当我在ssrs（Visual Studio 2015）中使用此查询时，它给出了一个错误，即定义查询参数。我已经为参数定义了值，但仍然得到错误。我觉得SQL查询中的某些内容在SSRS中得不到支持。有人可以帮忙吗？

Answer 1

确保您的参数名称和SQL变量拼写完全相同，它们区分大小写。

还可以尝试使用自己的DECLARE语句在自己的行上声明每个变量。我见过这个问题'有时'

Answer 2

您的参数位于@SQL查询变量中。您运行OPENQUERY的服务器无法识别参数，因为它们是在另一台服务器上声明的。

将参数声明放在SQL变量中：

set @code = '
declare
@start date = getdate() - 100
,   @end date = getdate()
...
