![]() ![]() We hope that this EDUCBA information on “Grant Privileges MySQL” was beneficial to you. Once we create a user in MySQL, we can grant privileges to the user at various levels and assign different privilege operations using the GRANT statement. We refer to this as proxy-level privilege granting, and we designate the user receiving the privileges as the proxy of the original user whose privileges are being granted. We can even grant all the privileges assigned to a particular user to some other user. Besides this, if we want to grant privileges on stored procedures, routines, and functions, then the same can be done by using ON PROCEDURE or ON FUNCTION statements in GRANT queries. To restrict certain privileges for a specific user, we can utilize the column privilege level in the GRANT statement by specifying the list of columns in a comma-separated format. Column, Stored Routine and Proxy Level Privilege Granting Table-level privileges are granted when we want to restrict the granting of privilege on a particular table of the database.For example, if we want to give DELETE privilege to grantdemo user on just educba_writers table, then we can use the following query –Ĥ. We can grant INSERT privilege on all the tables of the educba database to grantdemo user by using the following query – We need to specify name_of_database.* to mention the database level of privilege. When we want to grant the privileges to the user on all the tables of the ceratin database, then we can use the database privilege level. *.* is used to specify the global privilege level. This can be done by using the following query – Suppose we want to grant SELECT privilege on all the tables of all the databases to the grantdemo user. This is called granting privileges at the global level. We can grant certain privileges to the user that has the privilege level that is scope globally on all the tables of all the databases. ![]() Let us now see, one by one, how privileges on different levels can be assigned. How Privileges can be Assigned on Different Levels? For this, we will make the use of the following query statement where the privileges to be granted are mentioned in comm-separated format – For example, let us assign UPDATE, DELETE and INSERT privileges to the grantdemo user on the table educba_writers located in the educba database. We can even assign multiple privileges to the grantdemo user using the GRANT statement. You can accomplish this by using the following query statement: Using the GRANT statement, let us grant the select privilege on all the educba_writers tables of the educba database. It can just log in to the database but not access the contents and can neither modify them. We can see from the output that the newly created user does not have any grants assigned to it. Let us check all the granted privileges for this user using the following query statement – Let us create a new user named grant demo using the following create user statement, which we can use to grant privileges to. ![]() There are six privilege levels used for granting privileges to the user: global, database, table, column, stored procedure or function, and proxy, as shown in the below image. user_name: It is the name of the user to which you want to grant the privileges using the GRANT command.There can be six different privilege levels on which we can grant the permission or privilege to the user. specified_priv_level: The privilege level is the entity on which you want to assign the privilege to the user. ![]() We can grant multiple privileges to the single user on a particular entity by using the single grant command by specifying the privileges in a comma-separated manner after the GRANT keyword. specified_priv: It is the name of the privilege that is an operation that you want to permit and grant to the user named user_name.The syntax of the GRANT command that is used for assigning the privileges to the user to allow the access and operate on the database and its entities is as follows – Explanation: The root user has all the privileges on all the databases, its tables and columns of the tables, can perform any of the operations on them, and can grant the privileges to other users. ![]()
