Is there a way to specify a wild card in a json path?
For example I have the following json doc:
[ {“a”:1,”b”: [ { “x”: 7,”y”:8,”z”:9} ] }, {“a”:2,”b”: [ { “x”: 4,”y”:5,”z”:6} ] }, … ]
How do I write a select clause that can return the values for all b x values something like [{b:x}] that would return
allthe b:x values in the array? e.g. 7 and 4 ...
Also is there a definition of the syntax of a proper json path for use in postgres?
