How can I export a single trigger from mysql?
I need to re-create a single trigger in another mysql database - is there an easy way to export a single trigger?
What you want is a dump of single trigger of your db.
For example, this command export only the stored procedures and triggers:
mysqldump --routines --no-create-info --no-data --no-create-db --skip-opt <database> > outputfile.sql
However, I do not think you can dump a single trigger. Since it's only one, maybe it's easier to recreate another dabatase.
Can mysqldump dump triggers and procedures?, I normally do not separate triggers from the tables they were meant for. I dump like this: mysqldump -u -p --no-data --routines --triggers dbname > DBSchema. To show all triggers in all databases in a MySQL Server, you use this statement: SHOW TRIGGERS; For example, to show all triggers in the classicmodels database, you use this statement: SHOW TRIGGERS FROM classicmodels; This example shows all triggers associated with the employees table: SHOW TRIGGERS FROM classicmodels WHERE table = 'employees';
You can use this query to get a trigger definition directly out of MySQL:
SELECT ACTION_STATEMENT FROM INFORMATION_SCHEMA.TRIGGERS WHERE TRIGGER_SCHEMA = 'mydbname' AND TRIGGER_NAME = 'mytable_BEFORE_INSERT';
