stardog-admin [ --krb5 ] [ --krb5-disable-rdns ] [ --server <server url> ] function add [ --overwrite ] [ {-p | --passwd} <password> ] [ {-P | --ask-password} ] [ --run-as <username> ] [ --token <token> ] [ {-u | --username} <username> ] [ {-v | --verbose} ] [--] <function>

--krb5

Use the Kerberos environment.

--krb5-disable-rdns

Disable reverse DNS lookup for Kerberos clients.

--overwrite

Overwrite an existing stored function with the same name.

-p <password>, --passwd <password>

Password.

-P, --ask-password

Prompt for password.

--run-as <username>

User to impersonate when running the command

--server <server url>

URL of Stardog Server. If this option isn't specified, it will be read from JVM argument 'stardog.default.cli.server'. If the JVM arg isn't set, the default value 'http://localhost:5820' is used. If server URL has no explicit port value, the default port value '5820' is used. Example: 'stardog-admin --server http://12.34.56.78:5820 server stop'

--token <token>

Stardog JWT token

-u <username>, --username <username>

User name.

-v, --verbose

Flag that can cause more detailed information to be printed such as errors and status. Exact output depends upon the command and options used.

--

This option can be used to separate command-line options from the list of argument, (useful when arguments might be mistaken for command-line options

<function>

The definition of the stored function in the format "FUNCTION name([parameter[, parameter]*]) { <SPARQL expression> }".

Adds a new stored function. Stored functions assign a name to a SPARQL function expression and allows the expression to be executed in a SPARQL query by using the name. Stored functions can be used to query any database.

Adds a new stored function:

    $ stardog-admin function add "function permutation(?n, ?r) { factorial(?n) / factorial(?n - ?r) }"

Adds a new stored function overwriting previous function with same name:

    $ stardog-admin function add --overwrite "function combination(?n, ?r) { permutation(?n, ?r) / factorial(?r) }"

Adds multiple stored functions:

    $ stardog-admin function add "function permutation(?n, ?r) { factorial(?n) / factorial(?n - ?r) } \ 
                                   function combination(?n, ?r) { permutation(?n, ?r) / factorial(?r) }"
