Hi everyone,
I’m currently learning SQL and trying to create a trigger using Notepad for my MySQL database. I wrote the trigger script in Notepad and saved it as a .sql file. However, when I try to run it using the MySQL command line, I’m not sure if the syntax or formatting is correct.
Here’s what I’m trying to do: I want to automatically update a column in a table whenever a new row is inserted.
This is my sample trigger code:
DELIMITER //
CREATE TRIGGER update_timestamp
BEFORE INSERT ON employees
FOR EACH ROW
BEGIN
SET NEW.created_at = NOW();
END;
//
DELIMITER ;
When I run the file using this command:
bash
Copy
Edit
mysql -u root -p -D mydatabase < trigger_script.sql
I get an error, and I’m not sure if I’m missing something in Notepad formatting or syntax. Any advice or corrections would be appreciated!
Thanks in advance.
Dede
