Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
Note This issue also occurs in Microsoft SQL Server 2008.
The subquery lacks an inner join relationship for the [object_name] column in the condition of the subquery. Therefore, multiple rows are incorrectly returned, and the issue that is mentioned in the "Symptoms" section occurs.
Note The msdb.dbo.sp_sqlagent_get_perf_counters system stored procedure runs when a SQL Server performance condition alert is raised.
