select 1 from mytbl where cast(test_results#>'{ports,*,mean}' as float) >= 7 ;
But the "*" doesn't work :-(
Any ideas ?
If you have the option to not use data values in json field identifiers (i.e., object keys) you will avoid fighting against the system's underlying design choices. i.e., IMO, ports should contain an array, not an object.
I was under the impression that SQL/JSON Path (jsonpath) functions/operators solve some of these kinds of problems so try using that instead of the "fixed structure" access-based functions and operators.
