When you use sp_bindsession to bind two sessions, each session retains its isolation level setting.
You can change the transaction isolation level for the current session, but usually the default value is preferred.
READ is acquired automatically when Hibernate reads data under Repeatable Read or Serializable isolation level.
However, you can override the isolation level by using a table hint.
Depending on your isolation level and database capabilities this might not be required, but there is no downside if you always demarcate transactions explicitly.
With one exception, you can switch from one isolation level to another at any time during a transaction.
The snapshot isolation level is supported and exposed through ADO, OLE DB, SQLOLEDB, Shape Provider, SQLODBC, the OLE DB Managed Provider, and the SQL Managed Provider.
When UPDLOCK is specified, the READCOMMITTED and READCOMMITTEDLOCK isolation level hints are ignored.
Set the transaction isolation level to snapshot and start a transaction.
REPEATABLEREAD Perform a scan with the same locking semantics as a transaction running at the REPEATABLE READ isolation level.

A transaction always gets an exclusive lock on any data it modifies, andholds that lock until the transaction completes, regardless of the isolation level set for that transaction.
For example, if you set REPEATABLE READ in a batch, and the batch then calls a stored procedure that sets the isolation level to SERIALIZABLE, the isolation level setting reverts to REPEATABLE READ when the stored procedure returns control to the batch.
Because shared locks are held to the end of a transaction instead of being released at theend of each statement, concurrency is lower than the default READ COMMITTED isolation level.
