MySQL grant statements

1. Role: Authorization

grant general data user, the right to query, insert, update, delete all table data in the database
grant database developer, the authority to create tables, indexes, views, stored procedures, functions, etc.

2. Statement format

grant all[permissions][privileges] on library.table [email protected][if it is local, write this]identifield by 'password';

The difference between 1.library.* and library.table

1.Library.* is to give the user the corresponding permissions for all tables in this library, and the granted permissions can be used for all tables in the library

2. The library.* table has corresponding permissions for the tables specified in the user library, and the granted permissions cannot be used for non-specified tables in the library

2. View MySQL user permissions

1. View by own authority

show grants;

Example:

2. View other MySQL user permissions

show grants for [email protected];

Example:

3. Revoke privileges that have been granted to MySQL user privileges.

revoke has similar syntax to grant, just replace the keyword to with from:

revoke all【Permission】 on *.* from [email protected];
