Schema understanding in MySQL

after reading this article (introducing schema in the database)
https://www.biaodianfu.com/da.
, it is mentioned that the schema in MySQL is the same as the library. Is this correct?
Thank you

.

Yes, the description of the official document goes like this:

In MySQL, physically, a schema is synonymous with a database. You can
substitute the keyword SCHEMA instead of DATABASE in MySQL SQL syntax,
for example using CREATE SCHEMA instead of CREATE DATABASE.
MySQL Query : SELECT * FROM `codeshelper`.`v9_news` WHERE status=99 AND catid='6' ORDER BY rand() LIMIT 5
MySQL Error : Disk full (/tmp/#sql-temptable-64f5-1b3573e-4d632.MAI); waiting for someone to free some space... (errno: 28 "No space left on device")
MySQL Errno : 1021
Message : Disk full (/tmp/#sql-temptable-64f5-1b3573e-4d632.MAI); waiting for someone to free some space... (errno: 28 "No space left on device")
