I have this json in a mysql column.
{"items": [
{
"name": "a1",
"details": {"value": 1}
},
{
"name": "a2",
"details": {"value": 2}
},
{
"name": "a3"
},
{
"name": "a4",
"details": {"value": 4}
},
]
}
As you can see details is an optional field for each item. when i try to extract value from this column using JSON_EXTRACT(column, '$.items[*].details.value'), i get
[1,2,4] but i would like to get [1,2,null,4] instead. If the path does not exist, i would like to get null or any default value. Is it possible using mysql JSON_EXTRACT?
