Also, dot character is used in fully qualified names (my_db.my_table.my_column), that should be quoted separately: `my_db`.`my_table`.`my_column`. This is exactly wha CI4 is doing when finds a dot in DB config: treats it as a qualifier separator, and quotes parts before and after it separately.

Interesting thought, that database name in mySQL does not have a qualifier - this is covered in docs, https://dev.mysql.com/doc/refman/8.0/en/...fiers.html

However, in other DB engines (e.g. MS SQL, Oracle come to my mind) situation might be different: my_server.my_db.my_schema for instance.

So we could change it for particular DB Driver, if it makes sense at all.
 thanks for the reply. i got your point. i am using maria db with codeigniter 4.  here this point needs to remember that in codeigniter 3 version dot character is allowed in db name, while in codeigniter 4 is not being accpted.
