Preston Carman commented on ASTERIXDB-827:
------------------------------------------
Yes. The get-record-fields(record) expression returns the field details which
includes a field called "is-open". The "is-open" field is a `boolean` value for
if that filed is open or closed in the record.
Example:
let $r1 := {"id": 1,
"project": "AsterixDB",
"address": {"city": "Irvine", "state": "CA"},
"related": ["Hivestrix", "Preglix", "Apache VXQuery"] }
return get-record-fields($r1)
Query result is:
[ { "field-name": "id", "field-type": "INT64", "is-open": false },
{ "field-name": "project", "field-type": "STRING", "is-open": false
},
{ "field-name": "address", "field-type": "RECORD", "is-open": false,
"nested": [
{ "field-name": "city", "field-type": "STRING", "is-open": false },
{ "field-name": "state", "field-type": "STRING", "is-open": false }
] },
{ "field-name": "related", "field-type": "ORDEREDLIST", "is-open":
false, "list": [
{ "field-type": "STRING" },
{ "field-type": "STRING" },
{ "field-type": "STRING" } ] } ]
