MySQL provides an ALTER statement for stored functions. | |
The ALTER statement can change only the characteristics of a function, not the SQL statements that make up the body. | |
The ALTER statement has the following syntax: | |
You can change multiple characteristics within a single ALTER statement. | |
If a characteristic isn't specified in the statement, the value is left as it was when the function was created. | |
The DETERMINISTIC characteristic isn't allowed in the ALTER statement. | |
ALTER FUNCTION [database.] | |
