In the RETURN part of your query, you define which parts of the pattern you are interested in. It can be nodes, relationships, or properties on these.

14.16.1. Return nodes

To return a node, list it in the RETURN statemenet.

Query. 

MATCH n
WHERE n.name='B'
RETURN n

The example will return the node.

Result

n
1 row
0 ms

Node[2]{name:"B"}


14.16.2. Return relationships

To return a relationship, just include it in the RETURN list.

Query. 

MATCH (n)-[r:KNOWS]->(c)
WHERE n.name='A'
RETURN r

The relationship is returned by the example.

Result

r
1 row
1 ms

:KNOWS[0] {}


14.16.3. Return property

To return a property, use the dot separator, like this:

Query. 

MATCH n
WHERE n.name='A'
RETURN n.name

The value of the property name gets returned.

Result

n.name
1 row
1 ms

"A"


14.16.4. Return all elements

When you want to return all nodes, relationships and paths found in a query, you can use the * symbol.

Query. 

MATCH p=a-[r]->b
WHERE a.name='A'
RETURN *

This returns the two nodes, the relationship and the path used in the query.

Result

abrp
2 rows
1 ms

Node[1]{name:"A",happy:"Yes!",age:55}

Node[2]{name:"B"}

:KNOWS[0] {}

[Node[1]{name:"A",happy:"Yes!",age:55},:KNOWS[0] {},Node[2]{name:"B"}]

Node[1]{name:"A",happy:"Yes!",age:55}

Node[2]{name:"B"}

:BLOCKS[1] {}

[Node[1]{name:"A",happy:"Yes!",age:55},:BLOCKS[1] {},Node[2]{name:"B"}]


14.16.5. Identifier with uncommon characters

To introduce a placeholder that is made up of characters that are outside of the english alphabet, you can use the ` to enclose the identifier, like this:

Query. 

MATCH `This isn't a common identifier`
WHERE `This isn't a common identifier`.name='A'
RETURN `This isn't a common identifier`.happy

The node indexed with name "A" is returned

Result

This isn't a common identifier.happy
1 row
0 ms

"Yes!"


14.16.6. Column alias

If the name of the column should be different from the expression used, you can rename it by using AS <new name>.

Query. 

MATCH a
WHERE a.name='A'
RETURN a.age AS SomethingTotallyDifferent

Returns the age property of a node, but renames the column.

Result

SomethingTotallyDifferent
1 row
1 ms

55


14.16.7. Optional properties

If a property might or might not be there, you can select it optionally by adding a questionmark to the identifier, like this:

Query. 

MATCH n
RETURN n.age?

This example returns the age when the node has that property, or null if the property is not there.

Result

n.age?
2 rows
1 ms

55

<null>


14.16.8. Other expressions

Any expression can be used as a return item - literals, predicates, properties, functions, and everything else.

Query. 

MATCH a
WHERE a.name='A'
RETURN a.age > 30, "I'm a literal", a-->()

Returns a predicate, a literal and function call with a pattern expression parameter.

Result

a.age > 30"I'm a literal"a-->()
1 row
0 ms

true

"I'm a literal"

true


14.16.9. Unique results

DISTINCT retrieves only unique rows depending on the columns that have been selected to output.

Query. 

MATCH (a)-->(b)
WHERE a.name='A'
RETURN distinct b

The node named B is returned by the query, but only once.

Result

b
1 row
1 ms

Node[2]{name:"B"}
