Snapshot Isolation Concurrency Sql Server at Alannah Herbert blog

Snapshot Isolation Concurrency Sql Server. For more information about snapshot isolation, see snapshot isolation in sql server. Snapshot follows the optimistic model of concurrency, and this level of isolation takes a snapshot of the current data and uses it as a copy. It allows transactions to proceed without locks and with maximum concurrency, but may need to fail and rollback a transaction if two transactions attempt to modify the same data at the same time. Snapshot and read_committed_snapshot are two different isolation levels. Snapshot is isolation level you can use in your transaction explicitly as usual: For snapshot transactions, applications call sqlsetconnectattr with attribute set to sql_copt_ss_txn_isolation and valueptr set to sql_txn_ss_snapshot. If you want to use it with mixed read/write loads, prepare for update conflicts and be sure to. Read an overview of snapshot isolation and row versioning in sql server, and learn how to manage concurrency with isolation levels. Snapshot isolation level relies on optimistic concurrency control.
