User privileges
When using solidDB® databases in a multi-user environment, you may want to apply user privileges to hide certain tables from some users. For example, you may not want an employee to see the table in which employee salaries are listed, or you may not want other users to change your test tables.
You can apply five different kinds of user privileges. A user may be able to view, delete, insert, update or reference information in a table or view. Any combination of these privileges may also be applied. A user who has none of these privileges to a table is not able to use the table at all.
Note Once user privileges are granted, they take effect when the user who is granted the privileges logs on to the database. If the user is already logged on to the database when the privileges are granted, they take effect only if the user:
accesses for the first time the table or object on which the privileges are set, or
disconnects and then reconnects to the database.
