C# SQL Server中CLR存储过程的性能

我有一个SQL CLR存储过程，它解析TLVBER字符串，每次向DB发送命令时，都会调用此CLR过程，共有6个命令

这6个命令表示一个事务

在每个接收TLVBER字符串的命令中，我将该字符串解析为标记及其值，然后将其插入或更新到相应的列/表中。重要的是，这个标签存在于数据库中，我通过一个查询来验证它

要知道在哪个列/表中插入或更新了标记，我在DB中有一个表，我在其中存储

id\u标记

、表和列

问题是：

我不知道什么是更好的选择，因为我已经在CLR中编码了整个过程，我做了许多查询、插入和更新

举个例子，有一个问题是我必须创建一个临时表，我读到这不是推荐的，所以我用CLR解决这个问题，因为你可以使用ArrayList；总的来说，从C#编写代码比从T-SQL编写代码更容易

另一方面，我想在一个表中插入所有标记，然后 使用id引用这些标记，因为如果我将所有标记存储在一个 表中，我将存储发送到数据库的所有不同命令的标记

处理时间至关重要，因为每分钟将有数千个事务

在CLR中，我必须从DB查询数据（这些查询是否会影响CLR的时间进程？）

下一个问题是TLVBER解析的末尾，因为我需要连接解析的结果，比较解析的每个标记（每个标记用ArrayList迭代），并查询插入或更新的表/列。 我认为最好是构建查询，将其作为表返回到T-SQL，这样在T-SQL中的执行速度会比在CLR中更快

无论如何，我必须对数据库进行许多查询以获取信息，所以有没有办法将表发送到CLR SP？；为了避免从CLR进行查询，最好在T-SQL中查询必要的数据，并将其发送到CLR，这样可以处理数据，并且不会与DB进行任何交互（没有产生延迟的连接，只处理数据）

下面的代码向您展示了如何从T-SQL调用CLR，然后我向您展示了循环，在这里我进行查询、插入和更新
