The correct syntax for map data type in age

What is the correct syntax for the map age data type

{‘name’: ‘John’, ‘age’: 23}

Or

{‘name’: ‘John’; ‘age’: 23}

Pay attention to the separator , and ;. Both syntax have been used in the age docs. Are both valid or it’s just a typo?

You need the comma separator, ; is a typo

It is a typo for sure. You should use comma as a properties separator.
In action:
using ; separator outputs (not working):

test=# select * from cypher('test_graph', $$
test$# CREATE (n:Person {name:'mohamed'; age:12}) RETURN n; $$) as (res agtype);
ERROR:  syntax error at or near ";"
LINE 2: CREATE (n:Person {name:'mohamed'; age:12}) RETURN n $$) as ...

using , separator outputs (working):

select * from cypher('test_graph', $$
CREATE (n:Person {name:'mohamed', age:12}) RETURN n $$) as (res agtype);
                                               res

 {"id": 844424930131969, "label": "Person", "properties": {"age": 12, "name": "m
ohamed"}}::vertex
(1 row)

Referring to the Apache AGE manual: https://age.apache.org/age-manual/master/intro/types.html#accessing-list-elements-in-maps

using separator , is the correct way in the map syntax like the following example

SELECT *
FROM cypher('graph_name', $$
    WITH {int_key: 1, float_key: 1.0, numeric_key: 1::numeric, bool_key: true, string_key: 'Value'} as m
    RETURN m
$$) AS (m agtype);

Ref: Data Types in a AGE docs

For the map, you need to use ',' and not ':'.

This is explained in the link.

The correct syntax in your case would be:

> {'name': 'John', 'age': 23}

The use of semicolon as a separator is wrong. It is basically a typo or error.

The below query explains how to make a map using the cypher query:

SELECT *
FROM cypher('graph_name', $$
WITH {key: 1, lenght_value: 1.0, numeric_key: 1::numeric, bool_key: true, 
name: 'Waleed Ahmed Shahid'} as m
RETURN m
$$) AS (m agtype);

We can also create a map with composite data types.
The below query explains that:

SELECT *
FROM cypher('graph_name', $$
WITH {listKey: [{inner: 'Map1'}, {inner: 'Map2'}], mapKey: {i: 0}} as m
RETURN m
$$) AS (m agtype);

You can see from the above example that a map is being made and the nested maps and other variables have also been created in the above example.

You can consult the documentation for more understanding.

Documentation

The correct syntax for the map data type is the comma (,) as the separator between key-value pairs. Using (;) is a typo.

Basically, For map age data type, you must use (,) and (;) is a typo.

SELECT *
FROM cypher('graph_name', $$
    WITH {int_key: 1, float_key: 1.0, numeric_key: 1::numeric, bool_key: true, string_key: 'Value'} as m
    RETURN m
$$) AS (m agtype);

You can follow this tutorial & official docs.

The one with comma separator is valid not with semi-colon.

Apache AGE is primarily based on the property graph model and the correct syntax for the map data type is to use the comma (,) as the separator between key-value pairs. The semicolon (;) is not a valid separator.

The correct syntax for a map data type in AGE would be:

{ 'name': 'John', 'age': 23 }

This is a simple example showcasing the use of a map to store and represent the properties of a product entity in the AGE syntax.

It surely is a typo, comma is a valid separator and not semicolon.
