There are a few ways to handle duplicate specific values in SPARQL queries:
Example:
1 2 3 4 5 |
SELECT DISTINCT ?name WHERE { ?person a foaf:Person . ?person foaf:name ?name . } |
Example:
1 2 3 4 5 6 |
SELECT ?name (COUNT(?name) AS ?count) WHERE { ?person a foaf:Person . ?person foaf:name ?name . } GROUP BY ?name |
Example:
1 2 3 4 5 6 7 8 9 10 |
SELECT ?name WHERE { ?person a foaf:Person . ?person foaf:name ?name . } FILTER NOT EXISTS { ?person2 a foaf:Person . ?person2 foaf:name ?name . FILTER (?person != ?person2) } |
These are some ways to handle duplicate specific values in SPARQL queries. Choose the method that best suits your requirements and the complexity of your data.
