Is it possible to have cypher query paginated. For instance, a list of products, but I don't want to display/retrieve/cache all the results as i can have a lot of results.
I'm looking for something similar to the offset / limit in SQL.
Is cypher skip + limit + orderby a good option ? http://docs.neo4j.org/chunked/stable/query-skip.html
The UNION clause is used to combine the result of multiple queries.
The WITH clause allows query parts to be chained together, piping the results from one to be used as starting points or criteria in the next. It is important to note that WITH affects variables in scope. Any variables not included in the WITH clause are not carried over to the rest of the query.
CALL {} (subquery)
In the graph technology ecosystem, several query languages are considered declarative: Cypher, SPARQL and Gremlin (which also includes some imperative features, as mentioned above).
SKIP
and LIMIT
combined is indeed the way to go. Using ORDER BY
inevitably makes cypher scan every node that is relevant to your query. Same thing for using a WHERE
clause. Performance should not be that bad though.
Its like normal sql, the syntax is as follow
match (user:USER_PROFILE)-[USAGE]->uUsage where HAS(uUsage.impressionsPerHour) AND (uUsage.impressionsPerHour > 100) ORDER BY user.hashID SKIP 10 LIMIT 10;
This syntax suit to last version (2.x)
