This database-scoped system view is designed to provide an early warning system to determine objects that will be impacted by a major release upgrade in Azure SQL Database. You can use the view either before or after the upgrade to get a full enumeration of impacted objects. You will need to query this view in each database to get a full accounting across the entire server.
|Column name||Data Type||Description|
|class||int NOT NULL||The class of the object which will be impacted:
1 = constraint
7 = Indexes and heaps
|class_desc||nvarchar(60) NOT NULL||Description of the class:
|major_id||int NOT NULL||object id of the constraint, or object id of table that contains index or heap.|
|minor_id||int NULL||NULL for constraints
Index_id for indexes and heaps
|dependency||nvarchar(60) NOT NULL||Description of dependency that is causing a constraint or index to be impacted. The same value is also used for warnings generated during upgrade.
space (for intrinsic)
geometry (for system UDT)
geography::Parse (for system UDT method)
Requires the VIEW DATABASE STATE permission.
The following example shows a query on sys.dm_db_objects_impacted_on_version_change to find the objects impacted by an upgrade to the next major server version
SELECT * FROM sys.dm_db_objects_disabled_on_version_change; GO
class class_desc major_id minor_id dependency ------ ----------------- ----------- ----------- ---------- 1 OBJECT_OR_COLUMN 181575685 NULL geometry 7 INDEX 37575172 1 geometry 7 INDEX 2121058592 1 geometry 1 OBJECT_OR_COLUMN 101575400 NULL geometry
How to Update Impacted Objects
The following ordered steps describe the corrective action to take after the upcoming June service release upgrade.
|Order||Impacted Object||Corrective Action|
|1||Indexes||Rebuild any index identified by sys.dm_db_objects_impacted_on_version_change For example:
|2||Object||All constraints identified by sys.dm_db_objects_impacted_on_version_change must be revalidated after the geometry and geography data in the underlying table is recomputed. For constraints, revalidate using ALTER TABLE.
