MySQL Error 3511: Routine Comment Exceeds Max Length
Description
This error occurs when attempting to create or alter a MySQL routine (such as a stored procedure, function, or trigger) with a comment that exceeds the maximum allowed character length. MySQL imposes a specific limit on the size of comments associated with these database objects, and this error indicates that limit has been surpassed.
Error Message
Comment for routine '%s' is too long (max = %lu)
Known Causes
3 known causesExceeding MySQL's Comment Length Limit
MySQL enforces a hard limit on the number of characters allowed for routine comments (e.g., 64 characters). Providing a comment longer than this internal maximum will trigger the error.
Automated Tool Generates Long Comments
Some database management tools, ORMs, or scripts might automatically generate verbose comments during routine creation or modification, inadvertently pushing the comment length beyond MySQL's permissible limit.
Copy-Pasting Extensive Descriptions
Directly copying and pasting lengthy descriptions or documentation snippets into the routine comment field without shortening them can easily exceed the maximum allowed characters.
