How can I restrict a MySQL user to a particular tables

How can I restrict a user_account in MySQL database to a particular tables. Ex:

UserName: RestrictedUser
DatabaseName: db_Payroll 
TableName: 
  tb_Employees
  tb_Users
  tb_Payroll_YYMMDD
  tb_Payroll_Processed

I want to restrict "RestrictedUser" to tb_Users and tb_Employees only and the rest of the tables of db_Payroll that will be created for future use is granted to have access.

Solution

  • Assuming the user has no current privileges, you can do the following

    GRANT SELECT, INSERT, DELETE ON db_Payroll.tb_Users TO RestrictedUser@'%'
GRANT SELECT, INSERT, DELETE ON db_Payroll.tb_Employees TO RestrictedUser@'%'

    Depending on exactly which privileges you wish to grant the user, you can change SELECT, INSERT, DELETE to something else, e.g. ALL PRIVILEGES.

    Afterwards, remember to flush the privileges so they become effective by running

    FLUSH PRIVILEGES;
