As reference for others searching how to migrate MySQL triggers and landing on this issue page.
DELIMITER is a command only understood by MySQL client. You need to get rid of it in order to have sql-migrate sucessfully deploy the migration scripts.
Procedure:
-
First, make sure you have
multiStatements
enabled in your DSN. For example, indbconfig.yml
you would define a datasource like this:datasource: 'user:pass@tcp(db_host:db_port)/my_db?parseTime=true&multiStatements=true'
. -
Second, remove all DELIMITER commands from your sql code. For example, code looking like this:
DELIMITER $$
USE `my_db`$$
CREATE DEFINER = CURRENT_USER TRIGGER `my_db`.`my_table_BEFORE_INSERT`
BEFORE INSERT ON `my_table`
FOR EACH ROW
BEGIN
IF NEW.blah IS NULL THEN
SET NEW.blah = '';
END IF;
END$$
must be cleaned-up to look like this:
-- +migrate StatementBegin
USE `my_db`;
CREATE DEFINER = CURRENT_USER TRIGGER `my_db`.`my_table_BEFORE_INSERT`
BEFORE INSERT ON `my_table`
FOR EACH ROW
BEGIN
IF NEW.blah IS NULL THEN
SET NEW.blah = '';
END IF;
END;
-- +migrate StatementEnd
Note that there is no DELIMITER $$
present and all occurrences of $$
were replaced with ;

Hello,
Thank you for this great tool.
I was wondering if anyone has found a solution for migrating triggers.
This works from Sequel Pro IDE on a MySQL:
DROP TRIGGER IF EXISTS surveys.Survey_BEFORE_UPDATE;
DELIMITER $$
USE `surveys`$$
CREATE DEFINER = CURRENT_USER TRIGGER `surveys`.`Survey_BEFORE_UPDATE` BEFORE UPDATE ON `Survey` FOR EACH ROW
BEGIN
IF NEW.status != OLD.status OR
NEW.surveyGroupID != OLD.surveyGroupID OR
NEW.surveyMonth != OLD.surveyMonth OR
NEW.surveyYear != OLD.surveyYear THEN
INSERT INTO SurveyHistory (sequenceID,surveyGroupID,surveyYear,surveyMonth,`status`,statusAt,sentAt,lastActiveAt)
VALUES (OLD.id,OLD.surveyGroupID,OLD.surveyYear,OLD.surveyMonth,OLD.`status`,OLD.statusAt,OLD.sentAt,OLD.lastActiveAt);
END IF;
END$$
DELIMITER ;`
