Answer - TRANSACTION_READ_UNCOMMITTED OR TRANSACTION_READ_COMMITTED

The answer given above is wrong as Non-Repeatable Reads happen when a query returns data that would be different if the query were repeated within the same transaction. It can occur when other transactions are modifying data that a transaction is reading. Transaction_Read_Uncommitted or Transaction_Read_Committed. A session is created when a connection to a specific database gets created. SQL statements gets executed and the results gets return within the context of a connection.

Wrong answer

Actually, TRANSACTION_REPEATABLE_READ DOES NOT ALLOW non-repeatable reads in JDBC.
