在电子邮件中发送 CLR 存储过程结果

Question

我需要将 CLR 存储过程的结果（我无法更改 sproc/clr 程序集）作为 HTML 通过电子邮件发送。是否可以在不使用临时表或其他类型的持久化的情况下捕获和格式化存储过程的结果集（通过电子邮件发送）？

Answer 1

  USE msdb
  EXEC sp_send_dbmail
  @profile_name = 'MailProfile1',  --you will need to create this profile in the Database Mail under Management
  @recipients = 'test@email.com',
  @subject = 'CLR Sproc Resultset',
  @body = 'Resultset is attached.',
  @execute_query_database = '[DatabaseName]',
  @query = 'exec [DatabaseName].[SchemaName].[CLRProcName]'

试试这个，希望它能满足您的需要。

Answer 2

我在工作中使用 Ola Hallengren's SQL Server Maintenance Solution 进行数据库备份和索引优化。我写了几个不同的存储过程来在每晚作业完成时生成电子邮件，这样我就可以一目了然地看到每个数据库备份花费了多长时间，重建了多少索引和统计信息以及 tables，等等

下面是我为索引和统计写的存储过程。

您必须修改它以满足您自己的需要和源数据，但作为发送 HTML 电子邮件的模板，它应该适用于任何东西。

虽然你有一个 CLR 存储过程，但你必须创建一个与 SP returns 具有相同架构的临时 table，然后执行 INSERT EXEC 否则你会赢不能使用我的代码。
