In MySQL Workbench you can add comments to tables and columns in a MySQL database.
Does Sqlite support adding comments to tables and columns?
(This isn't what the original poster was asking, but this is what I was looking for when I first found this question based on the keywords in the title.)
There are two ways to make comments in SQLite code:
Hyphens
-- this is my comment
SELECT * FROM employees;
C-style
/* this is my comment */
SELECT * FROM employees;
