stored procedure alternative in mysql which can be altered - mysql

Question

1.) alternative for stored procedure in mysql which can be altered rather than drop and create again
2.) easy ways to maintain database version i am currently creating log.sql files manually such as example log.sql file
ALTER TABLE `ship`
CHANGE COLUMN `is_deleted` `is_deleted` INT(11) NULL DEFAULT 0 ;
DROP procedure IF EXISTS `get_ship`;
DELIMITER ;;
CREATE PROCEDURE `get_ship`(
)
BEGIN
do something;
end if;
END ;;
DELIMITER ;
Is there an better and easy way to create such sql log files,
I have already tried MYSQL workbench

Answer 1

When you are redefining a table structure with any of the following
drop column,
change column,
modify column,
add column,
rename table
and your stored procedure has dependency on the same table and its pre-defined columns,
then you don't have a choice but redefine part of your stored procedure.
And this can only be achieved by dropping and re-creating the procedure again.
As per documentation on ALTER PROCEDURE Syntax, in MySQL,
However, you cannot change the parameters or body of a stored procedure using this statement; to make such changes, you must drop and re-create the procedure using DROP PROCEDURE and CREATE PROCEDURE.
add column may not require re-building your stored procedure unless the new column too participates in the procedure's algorithm.
