Sql 如何管理不同条件下的查询？

我正在工作并试图根据这些条件管理我的查询

所有站点，所有状态

所有站点，具体状态

特定站点，所有状态

特定站点、特定状态

注意：在我的存储过程中，

0

表示所有，所有站=0，所有状态=0

存储过程：

和issue.fineIssuation.IssuanceDateTime那么问题是什么？你被困在哪里？一些样本数据。。。一些示例输出或所需输出。或者是一些错误。这是什么？我无法在其他条件下进一步管理它，请帮助上述条件是否适用于给定参数？是的，但我必须在每个条件上显示不同的数据。您需要指定
选项“重新编译”
，或者。通常，您可以使用一些（相当）简单的动态SQL来完成这类工作。旁注-您有日期/时间/时间戳。这正是我要建议的。该过程需要
选项重新编译
，否则参数嗅探将产生一些不良影响。我必须在每个条件上显示不同的数据，但您的代码即使在不同的条件块中也显示相同的数据。您想显示的不同数据在哪里？有些是我传递特定参数的，有些是我消除参数的
