Setting a list of maps through query parameters inside Neo4j browser

Neo4j Graph Platform
1

Hello,

While playing with queries using Neo4j Browser, sometimes is helpful to set query parameters in advance so those variables can be easily changed without modifying the query itself. I could do that with simple parameters or even maps:

:param {
    personName: "Val Kilmer",
    movieTitle: "Top Gun"
}

But, when I try to nest maps inside a list like the below I get a syntax error:

:param items => [
    {
        personName: "Val Kilmer",
        movieTitle: "Top Gun"
    },
    {
        personName: "Tom Cruise",
        movieTitle: "Top Gun"
    }
]

// Returns

Syntax error at line 2 col 0:

      {
  ^
Unexpected "\n".

Funny enough, it works while running the command in a single-line way:

:param items => [{personName: "Val Kilmer", movieTitle: "Top Gun"}, {personName: "Tom Cruise", movieTitle: "Top Gun"}]

Although, whenever I need to set many query parameters, the single-line approach above lacks readability.

Does anyone how to set a list of maps using that ":param" command in a multiline way?

Thank you.

I don't know, but you could author the json in a json formatter (online or locally) and format to 'minify' or 'compact' format and paste the single line in the browser. It renders nice if you return the parameters with ':params'

I've just find a way:

:param {
    items: [
        {
            personName: "Val Kilmer",
            movieTitle: "Top Gun"
        },
        {
            personName: "Tom Cruise",
            movieTitle: "Top Gun"
        }
    ]
}

@glilienfield thank you for your tip, but I was trying to avoid additional steps for this specific workflow I am working on.
