Question

What is the syntax for defining query parameters in th

Answer 1

In Neo4j Browser 3.5+ you can use the Cypher Shell parameter syntax, documented here: https://neo4j.com/docs/operations-manual/3.5/tools/cypher-shell/#cypher-shell-parameters

:param name => expression

The expression must be kept on a single line.

The expression could be a scalar or a list:

:param foo => ['a', 'b', 'c']

Maps can't be used directly with this syntax as of Neo4j 4.1. You can wrap them into a list:

:param foo => [{name: 'Alice', age: 38, address: {city: 'London', residential: true}}] 

Or you can use :params:

:params {foo: {name: 'Alice', age: 38, address: {city: 'London', residential: true}}}
