temporarily), it is best to use the INNER join on statement so that you never forget the type of join.
Joins are made temporarily at run time, and the more associated tables consume resources, so it's not necessary to don't mess with tables

MySQL has a built-in stop word list , it's the same as the short word, of course, this can also be manually modified, specific methods can search for information, check the document.
Many words appear so frequently that searching for them will be useless (returning too many results). As a result, MySQL grants 50% the rule that a word appears in 50% or more rows, which is treated as a deactivated word and is

this you know what is (and the rules and restrictions that govern them), let's look at View creation:
Views is created using the CREATE VIEW statement.
To view the statement used to create a view, use SHOW create view viewname;.
To remove a view, the DROP statement is used. The syntax is simply DROP VIEW viewname;.
To update a view the DROP statement and then the CREATE statement again, or just us E Create OR replace VIEW, which would create it if it does not exist and r
