stardog query -b

[Conrad Leonard]

A very minor issue, there is a regression or at least difference in behaviour of the results from stardog query -b var=value between 3.1.4 and 4.0.1:

In 3.1.4 a variable bound with -b option that appears (only) inside FILTER clause will appear in the result bindings, but not in 4.0.1.

A contrived example:

[conradL@qimr13054 ~]$ /software/stardog/stardog-3.1.4/bin/stardog query -u admin -p admin -b "study='UQCCR_GM'" -- grafli "SELECT * WHERE { ?s a :Study; rdfs:label ?sLabel . FILTER (str(?sLabel) = ?study) }"

+--------------------------------------------+------------+------------+

|                     s                      |   sLabel   |   study    |

+--------------------------------------------+------------+------------+

| study:779a848d-9239-4b8a-83d3-68b8c0873179 | "UQCCR_GM" | "UQCCR_GM" |

+--------------------------------------------+------------+------------+

Query returned 1 results in 00:00:00.321

In 4.0.1 the same gives (note no value for 'study' in results)

[conradL@qimr13054 ~]$ /software/stardog/stardog-4.0.1/bin/stardog query -b "study='UQCCR_GM'" -- grafli "SELECT * WHERE { ?s a :Study; rdfs:label ?sLabel . FILTER (str(?sLabel) = ?study) }"

+--------------------------------------------+------------+-------+

|                     s                      |   sLabel   | study |

+--------------------------------------------+------------+-------+

| study:779a848d-9239-4b8a-83d3-68b8c0873179 | "UQCCR_GM" |       |

+--------------------------------------------+------------+-------+

Query returned 1 results in 00:00:00.051
