The SET TRANSACTION statement is used to specify the characteristics of a transaction, such as its isolation level and read/write access.

Example: Setting Transaction Properties

SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
BEGIN TRANSACTION;
-- Transactional operations here
COMMIT;

Do's and Don'ts

Do's

• Use SET TRANSACTION to manage transaction behavior explicitly.
• Choose the appropriate isolation level based on the concurrency requirements.

Don'ts

• Don't use a high isolation level unless necessary, as it can reduce performance.
• Don't set transaction properties without understanding their impact on data consistency.
