sql - #tem_table 的对象名称无效

Question

我正在尝试执行查询以获得高 CpuUtilization 查询警报。如果我正在执行查询，它会显示结果。当我想使用 dbmail 将结果发送到我的邮件时，它抛出错误。

(3 row(s) affected)

(1 row(s) affected)

(1 row(s) affected)

Msg 22050, Level 16, State 1, Line 0 Error formatting query, probably invalid parameters Msg 14661, Level 16, State 1, Procedure sp_send_dbmail, Line 517 Query execution failed: Msg 208, Level 16, State 1, Server FSQADBTRVS\FSQADBTR, Line 1 Invalid object name '#PossibleCPUUtilizationQueries'.

这是我正在尝试运行的查询

Answer 1

EXEC msdb.dbo.sp_send_dbmail 将在不同的上下文中运行，并且对您声明的临时表没有权限。

改用全局临时表 (##PossibleCPUUtilizationQueries)。

正如 Aaron 非常正确地指出的那样，您也可以只使用永久表来存储数据，而不是使用临时表。

参见here有关本地和全局临时表的更多信息

There are two types of temporary tables: local and global. Local temporary tables are visible only to their creators during the same connection to an instance of SQL Server as when the tables were first created or referenced. Local temporary tables are deleted after the user disconnects from the instance of SQL Server. Global temporary tables are visible to any user and any connection after they are created, and are deleted when all users that are referencing the table disconnect from the instance of SQL Server.
