How could I create a user with specific user permissions, for example, I have a database called mydb, and it has these tables: users, contacts, messages, and I want to create a user called app_admin with the following permissions:
Create, Update & Drop tables
Insert, Update, Select & Delete data from tables
In order to do that what do I have to do?, Is it possible to do it in one line?
I know how to grant most of the privileges and create user in one line (thanks to Richard St-Cyr):
GRANT ALTER, CREATE, DELETE, DROP, INSERT, SELECT, UPDATE ON db.* TO 'app_admin'#localhost IDENTIFIED BY '_my_securePass';
FLUSH PRIVILEGES;
But what I don't want the user to be able to Drop the database.
yes you can, also try this example
GRANT ALL PRIVILEGES ON mydb.* TO 'app_admin'#'%' WITH GRANT OPTION
Yes, this can be done in 1 line by specifying the list of privileges instead of ALL. See http://dev.mysql.com/doc/refman/5.7/en/grant.html for the list of privileges.
GRANT ALTER, CREATE, DELETE, DROP, INSERT, SELECT, UPDATE ON db.* TO 'app_admin'#localhost IDENTIFIED BY '_my_securePass';
FLUSH PRIVILEGES;

Currently I have a master user in RDS like this
'master'#'%'
and I've create a user like this
'new_user'#'%'
As of now I can grant that user with these privileges
GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, RELOAD, PROCESS, REFERENCES, INDEX, ALTER, SHOW DATABASES, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE, REPLICATION SLAVE, REPLICATION CLIENT, CREATE VIEW, SHOW VIEW, CREATE ROUTINE, ALTER ROUTINE, CREATE USER, EVENT, TRIGGER ON *.* TO 'new_user'#'%' IDENTIFIED BY '1234' WITH GRANT OPTION
Is it possible to grant these permission but with the limit of
DELETE PRIVILEGE? on a specific table like this tblCart
Like, I can delete on all but except for table tblCart deleting is not allowed in this table?
The old answer is wrong. Since you didn't define DELETE ON *.tblCart this wont work. You will have to revoke DELETE on all and add them manually.
REVOKE DELETE ON *.* FROM `new_user`#`%`;
GRANT DELETE ON <db>.<tbl1> TO `new_user`#`%`;
...
GRANT DELETE ON <db>.<tblN> TO `new_user`#`%`;
See this post for how to generate the statement for all tables.
Old answer
After you applied your grants the way you did bove you can revoke permissions from tblCart like so:
REVOKE DELETE ON *.`tblCart` FROM `new_user`#`%`;
This will keep all permissions on all tables but remove permission do delete rows from tblCart.
I have a user, called "user_creator", in my MySQL 5.5.60 server. This user was created to add new user and databases and grant privileges to this new created users (so and "admin", but with fewer rights).
Following privileges for this "user_creator" are granted:
GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, INDEX, ALTER, SHOW DATABASES, CREATE TEMPORARY TABLES, LOCK TABLES, CREATE USER, EXECUTE, TRIGGER ON *.* TO 'user_creator'#'x.x.x.x' IDENTIFIED BY PASSWORD <secret> WITH GRANT OPTION
This configuration works well. If the "user_creator" creates a new user with...
GRANT SELECT, INSERT, UPDATE, DELETE ON foo.* TO 'foo_01'#'x.x.x.x' IDENTIFIED BY 'foo';
... it works.
But, if the "user_creator" want to grant the EXECUTE privilege to the new user, like
GRANT SELECT, INSERT, UPDATE, DELETE, EXECUTE ON foo.* TO 'foo_01'#'x.x.x.x' IDENTIFIED BY 'foo';
an error occurred:
ERROR 1044 (42000) at line 1: Access denied for user
‘user_creator'#'x.x.x.x’ to database ‘foo’;
Has anyone an idea which privilege the "user_creator" needs to grant the EXECUTE-privilege to a new created user? I don't want to user the root- or an root-like-user to do this action.
I am trying to give explicit permissions to an user on mysql and im doing this (to an already created user)
GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, INDEX, ALTER, SHOW DATABASES,
CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE, CREATE VIEW, SHOW VIEW,
CREATE ROUTINE, ALTER ROUTINE, EVENT, TRIGGER
ON mydatabase.*
TO 'myuser'#'localhost' ;
But im getting this weird error:
Incorrect usage of DB GRANT and GLOBAL PRIVILEGES
I tried on other schemas with other users making a GRANT ALL PRIVILEGES and seems is working. Any idea?
Some privileges only make sense when the grant references ON *.* as the schema.table.
The manual page https://dev.mysql.com/doc/refman/5.7/en/grant.html lists all the available privileges, and notes each for global, database, table, based on whether you can grant them at different levels of scope.
The SHOW DATABASES privilege can only be granted at the global level.
So you'll have to do it this way:
GRANT SHOW DATABASES
ON *.*
TO 'myuser'#'localhost' ;
GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, INDEX, ALTER,
CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE, CREATE VIEW, SHOW VIEW,
CREATE ROUTINE, ALTER ROUTINE, EVENT, TRIGGER
ON mydatabase.*
TO 'myuser'#'localhost' ;
I had the strange thing that the "root" user had the rights to grant rights, but I still had to use the user "admin" instead.
With root, I got:
SQL Error [1045] [28000]: Access denied for user 'root'#'%' (using password: YES)
It might just be the setup, but when I look it up in the GUI of DBeaver (Connection --> Users --> Grants --> View Grants), they both have all of the rights checked, and I still cannot grant rights with the "root" user.
Perhaps it helps someone with another weird db setup.

How to grant only few previleges ( to execute only DML and DDL statements) to the new user in MySQL ?
I tried the below command :
GRANT CREATE, ALTER, DROP, SELECT, INSERT, UPDATE, DELETE ON database.* to 'karthik' identified by 'shimoga';
But, it is showing Syntax error.
You need to take out identified by 'shimoga' from your statement.
CREATE USER:
CREATE USER 'karthik'#'instance' IDENTIFIED BY 'Password';
THEN GRANT Privileges:
GRANT SELECT, DELETE, UPDATE, EXECUTE, INSERT, DROP, ALTER, CREATE ON databaseName.* TO 'karthik'#'instancename';
Better Solution will be to create a Role. And assign the role to user.
This will make your job easier if you have many users that needs similar privileges.
First Create a Role:
CREATE ROLE IF NOT EXISTS 'Developer'#'localhost';
Then Assign the required Privileges to the Role.
GRANT SELECT, DELETE, UPDATE, EXECUTE, INSERT, DROP, ALTER ON databaseName.* TO 'Developer'#'instanceName';
Finally Assign the Role to User which you would have already created:
GRANT 'Developer'#'localhost' TO 'karthik'#'instanceName';
SET DEFAULT ROLE ALL TO 'karthik'#'instanceName';
I have a current mysql user who has SELECT privileges for all the table in database example. How can give that user privileges to add new tables, and alter/add records to the table it created?
Use the grant keyword combined with the table privileges you seek to give the user.
GRANT ALTER, CREATE ON example TO 'someuser'#'somehost';
MySQL Grant
MySQL Table Privileges
GRANT SELECT, INSERT, DELETE ON database TO username#'localhost' IDENTIFIED BY 'password';
You can use UPDATE in the list too.
maybe something like
GRANT ALL PRIVILEGES ON example . * TO 'user'#'%';
This gives all the privileges for ONLY the 'example' database to user
Old; but just because it comes first when you query about "mysql grants to create table"
GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, ALTER, LOCK TABLES, SHOW VIEW ON database.* TO 'user'#'host'
