MySQL Is there such a thing as too much comment

Question

I'm trying to do a DROP CREATE stored procedure in MySQL.

The first block of code runs just fine.

DELIMITER //
-- IMPORTANT: Change to ecom_prod
USE ecom_dev;


DROP PROCEDURE IF EXISTS `usp_getDetails`;

The second block gives an error in statement #2 near --DROP CREATE Procedure DROP PROCEDURE IF EXISTS usp_getDetails; at line 1

DELIMITER //
-- IMPORTANT: Change to ecom_prod
USE ecom_dev;

-- DROP CREATE Procedure
DROP PROCEDURE IF EXISTS `usp_getDetails`;

The only difference is the addition of extra comments. I can't understand how the extra comment is causing this error.

Any and all help is welcome

Answer 1

Once the DELIMITER is changed to something other than semicolon, the new delimiter should be used in place of the semicolon.

For example:

DELIMITER $$

-- IMPORTANT: Change to ecom_prod
USE ecom_dev$$

DROP PROCEDURE IF EXISTS `usp_getDetails`$$

DELIMITER ;

I'm not sure how your code is working with the semicolons. I don't think the issue has anything to do with the comments. But I haven't tested it. I always have a blank line preceding and following DELIMITER. And the only time I ever use DELIMITER is when I'm issuing a CREATE <stored_program_type>.
