Is it possible to override a ReadCommittedSnapshot isolation level with ReadCommitted isolation level for a...












0















The default isolation level of my database is "read committed snapshot". Please see the below screenshot.



read committed snapshot



I have the table "Tickets' with the following data in my database.



enter image description here



Now in connection 1, I am starting a new transaction with isolation level as "read committed". And I'm going to update the priority to 'medium' for the #TicketID "2"



enter image description here



From Connection 2, I am trying to access the details of #TicketID "2". And its still taking the value from the version store which is created by the read committed snapshot isolation, which is not expected behavior.



enter image description here



As per documentation, if a transaction using "read committed" isolation level, the row can't be accessed by any other transaction until the transaction performs a commit/Rollback.
Can anyone tell me why it is not happening in the given scenario? I am also curious to know, why a transaction level isolation is not able to override the default isolation level (here read committed snapshot) which is set at the database level?
