为啥 s-s-rS 在已经定义时要求定义查询参数？

【中文标题】为啥 s-s-rS 在已经定义时要求定义查询参数？

【英文标题】：why s-s-rS asking to Define query parameters when already defined?为什么 s-s-rS 在已经定义时要求定义查询参数？

【问题描述】：

我有以下在 SQL 中运行良好的查询。但是当我在 s-s-rs(Visual Studio 2015) 中使用这个查询时，它给了我一个错误，说定义查询参数。我已经为参数定义了值，但仍然出现错误。我从 s-s-rS 中不支持的 SQL 查询中感受到了一些东西。有人可以帮忙吗？

【参考方案1】：

确保您的参数名称和 SQL 变量的拼写完全相同，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。我已经看到这个“有时”解决了这个问题

【参考方案2】：

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

将参数声明放入您的 SQL 变量中：

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