WITH CHANGE_TRACKING_CONTEXT (Transact-SQL)
Enables the context of a change to be specified, such as an originator ID, when data is changed. For example, when using change tracking, an application might want to differentiate between changes that were made by the application itself and changes that were made to the data outside the application.
WITH CHANGE_TRACKING_CONTEXT ( context )
Is the contextual information that is supplied by the calling application and stored with the change tracking information for the change. context is varbinary(128).
The value can be a constant or a variable, but cannot be NULL.
The following example sets the change tracking context for a data change.
-- The tracked change is tagged with the specified context. DECLARE @originator_id varbinary(128); SET @originator_id = CAST('MyApplicationID' AS varbinary(128)); WITH CHANGE_TRACKING_CONTEXT (@originator_id) UPDATE Employees SET Salary = 50000 WHERE EmpID = 1 -- The change now has an associated change context. SELECT c.EmpID, c.SYS_CHANGE_CONTEXT FROM CHANGETABLE(CHANGES Employees, @last_sync_version) AS c;
