While set the transaction isolation level,isolation level changed after refreshing same isolation level is coming. Please suggest me how to fix this issue. Means mssqlserver by default isolation level is Read committed . I was changed to Read uncommitted. But after refreshing it shows again Read committed.

That was pretty useful. But as far as I have read, the Isolation Level can’t be changed at Server level, then i guess using this DBCC command in any connection will give the same restult ?

BEGIN TRANSACTION

BULK INSERT ………
…………………….

COMMIT TRANSACTION

if the bulk insert operation is performed by more than one user at the same time . then there is a deadlock occurs. How can I avoid this situation. which type of isolation level is needed?

select session_id, host_name, login_name, transaction_isolation_level from sys.dm_exec_sessions where original_login_name = ‘Your Account’

for view the isolation level of a user.

transaction_isolation_level:

1 = ReadUncomitted

2 = ReadCommitted

3 = Repeatable

4 = Serializable

5 = Snapshot

How to find which isolation will be used in command prompt ?
and How should we found it?

SELECT name, snapshot_isolation_state_desc, is_read_committed_snapshot_on FROM sys.databases

We set isolation level at transation level or set a connection level.

So every time, we open a transation, a connection / session level isolation value get applies to a transation.

Correct me, if I am not correct .

Example:
select
CASE is_read_committed_snapshot_on
WHEN 1 THEN ‘Read Committed Snapshot’
ELSE ‘Read Committed’
END as TransactionIsolationLevel
from sys.databases
where database_id = DB_ID()

As for the original question, do databases have isolation levels? It’s connections that operate under a transaction isolation level, as I understand it.
