Merging two arrays

Hi there,

I have 2 arrays that I need to merge; I have used Merge in Join Snap but they are not coming in as Output below. seems simple but missing something.

Any guidance?

Thanks
Manohar

INPUT

**Array 1**
[
  {
    "order-lines": [
      {
        "line-num": "00010",
        "attachments": {
          "type": "AttachmentText",
          "intent": "Supplier",
          "text": "2021-08-25 09:57 :-  Test"
        },
        "description": "Test 31103"
      }
    ]
  }
]
**Array 2**
[
  {
    "order-lines": [
      {
        "line-num": "00020",
        "description": "Test 31104"
      },
      {
        "line-num": "00030",
        "description": "Test 10220"
      }
    ]
  }
]

OUTPUT

[
  {
    "order-lines": [
      {
        "line-num": "00010",
        "attachments": {
          "type": "AttachmentText",
          "intent": "Supplier",
          "text": "2021-08-25 09:57 :-  Test"
        },
        "description": "Test 31103"
      },
      {
        "line-num": "00020",
        "description": "Test 31104"
      },
      {
        "line-num": "00030",
        "description": "Test 10220"
      }

    ]
  }
]

Hi @manohar ,

After the input data you can use JSON Splitter to split the input data on $order-lines, then simply use Group by N with the following

Result:

[
  {
    "order-lines": [
      {
        "line-num": "00010",
        "attachments": {
          "type": "AttachmentText",
          "intent": "Supplier",
          "text": "2021-08-25 09:57 :-  Test"
        },
        "description": "Test 31103"
      },
      {
        "line-num": "00020",
        "description": "Test 31104"
      },
      {
        "line-num": "00030",
        "description": "Test 10220"
      }
    ]
  }
]

This is assuming you have only one data source, if you have two then use Join with following setting

After this use Mapper with the following expression


You get the same result.

that did the trick. thanks @j.angelevski

@j.angelevski , I have one problem here…

when concatenating, its concatenating Array1 followed by Array2, which is good. but however I need that to be ordered by line-num value. as not always its will be that order.


**Array 1**
[
  {
    "order-lines": [
      {
        "line-num": "00010",
        "attachments": {
          "type": "AttachmentText",
          "intent": "Supplier",
          "text": "2021-08-25 09:57 :-  Test"
        },
        "description": "Test 31103"
      },
      {
        "line-num": "00030",
        "attachments": {
          "type": "AttachmentText",
          "intent": "Supplier",
          "text": "2021-08-25 09:57 :-  Test"
        },
        "description": "Test 1313"
      }
    ]
  }
]
**Array 2**
[
  {
    "order-lines": [
      {
        "line-num": "00020",
        "description": "Test 31104"
      }
    ]
  }
]

Output should be

[
  {
    "order-lines": [
      {
        "line-num": "00010",
        "attachments": {
          "type": "AttachmentText",
          "intent": "Supplier",
          "text": "2021-08-25 09:57 :-  Test"
        },
        "description": "Test 31103"
      },
      {
        "line-num": "00020",
        "description": "Test 31104"
      },
      {
        "line-num": "00030",
        "attachments": {
          "type": "AttachmentText",
          "intent": "Supplier",
          "text": "2021-08-25 09:57 :-  Test"
        },
        "description": "Test 1313"
      }
    ]
  }
]

May I know how I can achieve that?

Thanks
Manohar

@manohar ,
You can use jsonPath($, "order-lines.sort_asc(value['line-num'])"), this will sort the $order-lines array.

Thanks @j.angelevski. wondering can I add that to Concat mapper itself? I used your concat.

@manohar , this only works with jsonPath($, “”), if you want to use it directly to an array the you need to use the built-in array function .sort(). @bojanvelevski already gave you a solution for that: Sort internal array - #2 by bojanvelevski
