Multiple choiceHardchapter-8-curatedpremiumsql-for-java-devsrepository-pattern
Connection conn = DriverManager.getConnection(url, user, password);
conn.setAutoCommit(false);
// perform operations
conn.commit();Answer and explanation
Correct answer
A. Lack of proper exception handling can lead to uncommitted transactions.
Why
Without proper exception handling, if an exception occurs after setAutoCommit(false), the transaction may be left uncommitted or rolled back, potentially leading to data inconsistencies. Always ensure transactions are handled in a try-catch block.
