# derby.database.readOnlyAccessUsers

#### Function

One of the user authorization properties. Specifies a list of users to which read-only access to a database is granted. The list consists of user names separated by commas. Do not put spaces after commas.

When set as a system property, specifies a list of users for which read-only access to all the databases in the system is granted.

See also derby.database.fullAccessUsers.

A malformed list of user names raises an exception. Do not specify a user both in this property and in derby.database.fullAccessUsers.
Note: User names, called authorization identifiers, follow the rules of SQL92Identifiers and can be delimited. Specifying a user name that does not follow these rules raises an exception.

#### Syntax

    -- database-level property
    CALL SYSCS_UTIL.SYSCS_SET_DATABASE_PROPERTY(
        'derby.database.readOnlyAccessUsers',
        'commaSeparatedListOfUsers')

#### Example

    -- database-level property
    CALL SYSCS_UTIL.SYSCS_SET_DATABASE_PROPERTY(
        'derby.database.readOnlyAccessUsers', 'ralph,guest')
    -- system-level property
    derby.database.readOnlyAccessUsers=ralph,guest
