Graph Data Processing with Cypher
By :

In this chapter, we looked at building queries while applying filters. We have taken a look at filtering the data using node labels and relationship types, using relationship directions, the performance impact of using node labels when compared to relationship types for traversal, using WHERE
clauses, WITH
clauses, SKIP
clauses, LIMIT
clauses, and EXISTS
clauses, and using regular expressions.
We looked at sorting the data using the ORDER BY
clause with one value or multiple values in ascending order or in descending order and combining the ORDER BY
clause with the WITH
clause.
Finally, we looked at aggregating results using the COUNT
, COLLECT
, MIN
, MAX
, and AVG
functions. Along with this, we also looked at combining the COUNT
and COLLECT
functions to perform some complex aggregations.
In the next chapter, we will take a look at using LIST
expressions, working with the UNION
clause. We will also take a look at using sub-queries using the CALL
clause.
