Incorrect Results with Indexed Views <\/a>(blog<\/a> | @SQL_Kiwi<\/a>)<\/li>\n<\/ul>\n
I won’t rehash what they have collectively\u00a0already covered thoroughly – but just a quick tip about identifying index view and MERGE\u00a0optimization activity\u00a0via the sys.dm_exec_query_optimizer_info DMV…\u00a0 The following query shows counter\u00a0name\u00a0and\u00a0occurrences of optimizations for MERGE statements and indexed views having been matched\u00a0since the SQL Server instance last restarted:<\/p>\n
```
\r\nSELECT\u00a0 [counter],\r\n[occurrence]\r\nFROM sys.[dm_exec_query_optimizer_info]\r\nWHERE counter IN\r\n('merge stmt',\r\n'indexed views matched');\r\n<\/pre>\nI see this as a “first cut” check – but there are some key limitations to why this would only be a starting data point and not the “end all, be all” approach:<\/p>\n\nAs mentioned earlier,\u00a0occurrences are as of the last restart of SQL Server – and you could still be impacted by the issue\u00a0– but a specific workload may not have been executed yet<\/li>\nThe counters\u00a0are instance level – so you will not know which databases\u00a0were specifically associated with the activity\u00a0and whether this is an actual MERGE + indexed view combo as described in the aforementioned blog posts<\/li>\n<\/ul>\nEven with the limitations, if you see non-zero values for the counters, this might accelerate your investigation and application of the appropriate cumulative update<\/a>.\u00a0 I prefer keeping up with serious issues in this case, but if you need to prioritize what gets patched in larger environments with thousands of SQL Server instances, this may help drive that prioritization.<\/p>\n","protected":false},"excerpt":{"rendered":"
