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')
