“Data too long for column” - why?

Question

I\'ve written a MySQL script to create a database for hypothetical hospital records and populate it with data. One of the tables, Department, has a column named Description,

Answer 1

For me, I defined column type as BIT (e.g. "boolean")

When I tried to set column value "1" via UI (Workbench), I was getting a "Data too long for column" error.

Turns out that there is a special syntax for setting BIT values, which is:

b'1'
