What you get with this Offer
I will develop up to 4 MySQL stored procedures, functions, or triggers — covering parameterised PROCEDURE and FUNCTION creation, DECLARE HANDLER for error handling, transaction management with START TRANSACTION, COMMIT, and ROLLBACK, DELIMITER configuration, and AFTER INSERT/UPDATE/DELETE triggers for audit logging and denormalisation maintenance. MySQL stored procedures written without DECLARE HANDLER for SQLEXCEPTION allow errors to propagate without rollback, leaving transactions in indeterminate states; triggers without DETERMINISTIC or NO SQL / READS SQL DATA / MODIFIES SQL DATA declarations cause replication problems on binary log-based replicas.
Each object covers correct DELIMITER syntax, DECLARE HANDLER for SQLEXCEPTION with rollback, cursor management for row-by-row processing where unavoidable, and a unit test script. Trigger objects include replication-safe declaration and a test script confirming correct firing on the specified DML event.
This service suits development teams and businesses who need MySQL business logic implemented as correctly written, error-handled stored routines rather than application-layer SQL strings.

What the Freelancer needs to start the work
Please provide functional specifications for each object, your table schemas, your MySQL version, access to a development database for testing, and whether binary log replication is in use (affects trigger declaration requirements).
