Question

我正在尝试执行查询以获取highCpuUtilization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，它会抛出错误。

（3行受影响）

（1行受影响）

（1行受影响）

消息22050，级别16，状态1，行0可能是格式化查询错误   无效参数消息14661，级别16，状态1，过程   sp_send_dbmail，第517行查询执行失败：消息208，级别16，   状态1，服务器FSQADBTRVS \ FSQADBTR，第1行无效的对象名称   '#PossibleCPUUtilizationQueries'。

这是查询，我正在尝试运行

DECLARE @ts_now bigint 
DECLARE @SQLVersion decimal (4,2) -- 9.00, 10.00
DECLARE @AvgCPUUtilization DECIMAL(10,2) 

SELECT @SQLVersion = LEFT(CAST(SERVERPROPERTY('PRODUCTVERSION') AS VARCHAR), 4) -- find the SQL Server Version

-- sys.dm_os_sys_info works differently in SQL Server 2005 vs SQL Server 2008+
-- comment out SQL Server 2005 if SQL Server 2008+

-- SQL Server 2005
--IF @SQLVersion = 9.00
--BEGIN 
--  SELECT @ts_now = cpu_ticks / CONVERT(float, cpu_ticks_in_ms) FROM sys.dm_os_sys_info 
--END

-- SQL Server 2008+
IF @SQLVersion >= 10.00
BEGIN
    SELECT @ts_now = cpu_ticks/(cpu_ticks/ms_ticks) FROM sys.dm_os_sys_info
END

-- drop the temp tables
IF OBJECT_ID('TEMPDB..#CPUUtilization') IS NOT NULL
drop table #CPUUtilization

IF OBJECT_ID('TEMPDB..#PossibleCPUUtilizationQueries') IS NOT NULL
drop table #PossibleCPUUtilizationQueries

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。

改为使用全局临时表（##PossibleCPUUtilizationQueries）。

正如Aaron非常正确地指出你也可以使用永久表来存储数据而不是使用临时表。

有关本地和全局临时表的更多信息，请参阅here

临时表有两种类型：本地和全局。本地临时表仅在其创建者期间可见表格首次连接到SQL Server实例创建或引用。在删除本地临时表后用户断开与SQL Server实例的连接。全球临时表对任何用户和任何连接都可见创建，并在引用该表的所有用户时删除断开与SQL Server实例的连接。
