Which are the different IsolationLevels ?

Answer Posted / swapna

Serialized : Data read by a current transaction cannot be
changed by another transaction until the current
transaction finishes. No new data can be inserted that
would affect the current transaction. This is the safest
isolation level and is the default.


Repeatable : Read Data read by a current transaction
cannot be changed by another transaction until the current
transaction finishes. Any type of new data can be inserted
during a transaction.


Read Committed : A transaction cannot read data that is
being modified by another transaction that has not
committed. This is the default isolation level in
Microsoft? SQL Server.

Read Uncommitted : A transaction can read any data, even
if it is being modified by another transaction. This is the
least safe isolation level but allows the highest
concurrency.


Any Any isolation level is supported. This setting is
most commonly used by downstream components to avoid
conflicts. This setting is useful because any downstream
component must be configured with an isolation level that
is equal to or less than the isolation level of its
immediate upstream component.

Therefore, a downstream component that has its isolation
level configured as Any always uses the same isolation
level that its immediate upstream component uses. If the
root object in a transaction has its isolation level
configured to Any, its isolation level becomes Serialized.
