I have a json for country
Table column: countryJson
Sample Json : [ { name:india,
population: 1000M,
type: country,
children: [
{
name: karnataga,
population: 30M,
type:state,
children: [ {
name: bangalore,
population: 10M,
type:district },
{
name: mysore,
population: 2M,
type:district
},
]
}
]
}]
I need to index country name, state name and district name. I need to find
districts with population greater than 5M. How to query districts with
statename = karnataga and country name = india?
i.e select countryJson[ name =''india"].children[name="karnataga"].children
[population] > 5m?
Is it supported in postgresql? i.e better examples on array value indexes and
array value criteria would help me to use easily use json.
cheers
