SYNOPSIS¶

oxigraph query <-l|--location> [-q|--query] [--query-file] [--query-base] [-r|--results-file] [--results-format] [--explain] [--explain-file] [--stats] [--union-default-graph] [-h|--help]

DESCRIPTION¶

Execute a SPARQL query against the store

OPTIONS¶

-l, --location=LOCATION

Directory in which Oxigraph data are persisted

-q, --query=QUERY

The SPARQL query to execute

If no query or query file are given, stdin is used.

--query-file=QUERY_FILE

File in which the query is stored

If no query or query file are given, stdin is used.

--query-base=QUERY_BASE

Base IRI of the query

-r, --results-file=RESULTS_FILE

File in which the query results will be stored

If no file is given, stdout is used.

--results-format=RESULTS_FORMAT

The results format

It can be an extension like "nt" or a MIME type like "application/n-triples".

By default the format is guessed from the results file extension.

--explain

Print to stderr a human-readable explanation of the query evaluation

Use the stats option to print also query evaluation statistics.

--explain-file=EXPLAIN_FILE

Write to the given file an explanation of the query evaluation

If the file extension is .json the JSON format is used, if .txt a human readable format is used.

Use the stats option to print also query evaluation statistics.

--stats

Compute some evaluation statistics to print as part of the query explanations

Beware, computing the statistics adds some overhead to the evaluation runtime.

--union-default-graph

If the SPARQL queries should look for triples in all the dataset graphs by default (ie. without `GRAPH` operations)

-h, --help

Print help (see a summary with '-h')
