TINYSPARQL-QUERY(1)	       TinySPARQL manual	   TINYSPARQL-QUERY(1)

NAME
       tinysparql-query	- Query	to SPARQL endpoints.

SYNOPSIS
       tinysparql query	[(-d |--database) <file> | (-b | --dbus-service) <busname> | (-r | --remote-service) <url>]
	   (-f | --file) <file>] [(-u |	--update)] [-a <parameter>:<value>]... [SPARQL]

DESCRIPTION
       This command allows running queries or updates on a SPARQL endpoint.

       When the	caller runs a query, the query is in the SPARQL	language. This
       can be done two ways. Either by providing a file	with the query or by
       providing a string with the sparql query.

       The file	argument can be	either a local path or a URI. It also does not
       have to be an absolute path.

OPTIONS
       -b, --dbus-service=<service_name>
	   Connects to a SPARQL	endpoint at a D-Bus name.

       -d, --database-path=<database_path>
	   Connects to a database by location in the filesystem.

       -r, --remote-service=<url>
	   Connects to a HTTP SPARQL endpoint.

       -f, --file=<file>
	   Use a file with SPARQL content to query or update.

       -u, --update
	   This	has to be used with --query. This tells	"tinysparql query" to
	   use the SPARQL update extensions so it knows	it isn't a regular
	   data	lookup request.	So if your query is intended to	change data in
	   the database, this option is	needed.

       -a, --arg=<parameter>:<value>
	   Provides an argument	for a parameter	declared in the	SPARQL query
	   string. This	may be used with --file, --query or --update. Multiple
	   arguments may be provided for multiple parameters. Argument values
	   are provided	as a colon separated string containing 3 values: name,
	   type	and value. The name is the same	as used	in the query string,
	   the value is	the desired value, and the type	is a single-character
	   string defining the type:

	      i: The value will describe an integer

	      d: The value will describe a floating point number

	      b: The value will describe a boolean

	      s: The value will describe a plain string

EXAMPLES
       Querying	a D-Bus	endpoint

	       $ tinysparql query --dbus-service org.example.Endpoint "SELECT ('Hello World' AS	?str) {}"

       Updating	a database directly from a query in a file

	       $ tinysparql query --database /tmp/db/ --update --file ./update.rq

       Using --arg to provide a	arguments to query parameters

	       $ tinysparql query -b org.example.Endpoint \
		   -a name:s:"John" -a age:i:42	-a available:b:true \
		   "SELECT (~name AS ?name) (~age AS ?age) (~available AS ?avail) { }"
