QQ - How do I dynamically create a banded field in script?

Banded fields group numeric data into "bins" that have specified upper and lower limits.   Various options are available for controlling banding through the Banded Field dialog.   

To create the kind of banded field that will dynamically calculate bins depending on the source data, use the Engineering | Banded Fields | Auto option.

This will bring up the Auto Banded Field dialog:

The following is an example of a JSON method used to create an Auto-banded field:

{
  "method": "BuildBakedField",
  "project": "DemoPrep6",
  "targetTable": "03_HEADER",
  "p1": "phone_no",
  "overwrite": true,
  "name": "phone_no_banded",
  "auto": true,
  "bands": 10,
  "named": true,
  "function": "numberband",
  "dataSet": {
    "logic": "or",
    "name": "state_AK",
    "strict": true,
    "set": [
      {
        "logic": "and",
        "stype": "FIELD",
        "entity": {
          "type": "field",
          "name": "03_HEADER.state",
          "table": "03_HEADER",
          "valueFilter": []
        },
        "op": "=",
        "values": [
          "AK"
        ]
      }
    ]
  }
}
