Returns information about what missing indexes are contained in a specific missing index group, excluding spatial indexes.
In Azure SQL Database , dynamic management views cannot expose information that would impact database containment or expose information about other databases the user has access to. To avoid exposing this information, every row that contains data that doesn’t belong to the connected tenant is filtered out.
|Column name||Data type||Description|
|index_group_handle||int||Identifies a missing index group.|
|index_handle||int||Identifies a missing index that belongs to the group specified by index_group_handle.
An index group contains only one index.
Information returned by sys.dm_db_missing_index_groups is updated when a query is optimized by the query optimizer, and is not persisted. Missing index information is kept only until SQL Server is restarted. Database administrators should periodically make backup copies of the missing index information if they want to keep it after server recycling.
Neither column of the output result set is a key, but together they form an index key.
To query this dynamic management view, users must be granted the VIEW SERVER STATE permission or any permission that implies the VIEW SERVER STATE permission.
