Schema Privileges

The Privileges panel of the MySQL Model page is used to create users for your schemata and also to define roles —.

The Schema Privileges panel is divided up into the following sections:

  • Users

  • Roles

The following image displays the Schema Privileges section of the MySQL Model tab.

To add a role, double-click the Add Role icon. Doing this creates a role with the default name role1. Right-clicking a role opens a pop-up menu with the following options:

  • Cut 'role_name': Cut the role

  • Copy 'role_name': Copy the role

  • Edit Role ...: Open the role editor.

  • Edit in New Window: Open the role editor in a new editor window.

  • Delete 'role_name': Remove the role

  • Copy SQL to Clipboard: Currently not implemented.

To rename a role, simply click the role name and you will then be able to edit the text.

All roles that have been defined are listed under Roles on the left side of the role editor. Double-clicking a role object opens the role editor docked at the bottom of the screen.

Role editor

Select the role that you wish to add objects to. You may drag and drop objects from the Physical Schemata to the Objects section of the role editor. To assign privileges to a role select a role from the Roles section and then select an object in the Objects section. In the Privileges section check the rights you wish to assign to this role. For example, a web_user role might have only SELECT privileges and only for database objects exposed through a web interface. Creating roles can make the process of assigning rights to new users much easier. Adding Users

To add a user double-click the Add User icon. Doing this creates a user with the default name user1. Double-clicking this user opens the user editor docked at the bottom of the application.

In the User Editor, set the user's name using the Name text box and set the password using the Password text box. Assign one role or a number of roles to the user by selecting the desired roles from the text area on the right and then clicking the < button. Roles may be revoked by moving them in the opposite direction.

Right-clicking a user opens a pop-up menu. These options function as described in Section, “Adding Roles”.
