The SET TRANSACTION statement sets the properties of a transaction, such as the isolation level or access mode.

Example: Setting Isolation Level

SET TRANSACTION ISOLATION LEVEL READ COMMITTED;
BEGIN TRANSACTION;
-- Perform operations
COMMIT;

Do's and Don'ts

Do's

• Set the appropriate isolation level based on transaction requirements.
• Use SET TRANSACTION to fine-tune transaction behavior for performance and consistency.

Don'ts

• Don't set a high isolation level unless necessary, as it may impact performance.
• Don't overlook the effects of isolation levels on concurrency and data integrity.
