Posted on by ndpro

Hi All,

I am getting below Json array and want to filter values.

[{

"start": {

"dateTime": "2022-07-29T07:00:00.0000000",

"timeZone": "UTC"

"end": {

"dateTime": "2022-07-29T07:30:00.0000000",

"timeZone": "UTC"

}

]

I used below query to filter the date time time value with current date but its not returning any data.

item()?['start']?['datetime']

how we use filter query for getting the values.

Hi @ndpro

In your example you have an array with a single object containing a start and end object. Whilst you can call the start and end object by key name, the main object {} needs to be called by integer index or by using the first() expression. Item is generally used within a loop / apply to each or select.

But based on what is visible in your question, this should work:

first(item())?['start']?['datetime']

OR

item()?[0]?['start']?['datetime']

@DamoBird365 Thanks for quick response.

I am not having single object and its containing more than 100 objects. I copied only single object in array. I need to filter whole json file with start datetime with current date.

[{

    "start": {
      "dateTime": "2022-07-29T07:00:00.0000000",
      "timeZone": "UTC"
    },
    "end": {
      "dateTime": "2022-07-29T07:30:00.0000000",
      "timeZone": "UTC"
    }
},
{

    "start": {
      "dateTime": "2022-07-29T07:00:00.0000000",
      "timeZone": "UTC"
    },
    "end": {
      "dateTime": "2022-07-29T07:30:00.0000000",
      "timeZone": "UTC"
    }
},
{

    "start": {
      "dateTime": "2022-07-29T07:00:00.0000000",
      "timeZone": "UTC"
    },
    "end": {
      "dateTime": "2022-07-29T07:30:00.0000000",
      "timeZone": "UTC"
    }
},
]

Hi @ndpro

You can use a select to repurpose your array and provide an output as follows:

I have put your array into a compose (you have a spare , after the last object which I have remove and then I have created the following select:

item()?['start/datetime']

item()?['end/datetime']

If you want to filter on the original array, you can do the following:

I updated the three start dates to 27,28 and 29 and the output was 2 of the 3 objects based on the above filter.

@ndpro of course you might just be looking for a way to format the current date?

formatDateTime(utcNow(),'yyyy-MM-dd') so that it is the same format as the date in your array.
