  2. 2Table name is empty
  3. 3Table name exceeds 64 characters
How to reproduce
trigger — this will error
trigger — this will error
CREATE TABLE `my.table` (id INT);

expected output

ERROR 1163 (42000): Incorrect table name 'my.table'

Fix

Use only valid characters in table names

WHEN Always.

Use only valid characters in table names
CREATE TABLE my_table (id INT);

Why this works

Table names should use only letters, digits, and underscores; avoid dots, slashes, and other special characters.

What not to do

✕ Use dots in table names expecting them to act as schema separators

In MySQL the dot separates the database from the table name (db.table); a dot inside a table name makes it invalid.
