Getting data from json using jq when key is numerical string

Question

I am new to jq and facing an issue while parsing my json

I have a json stored in a variable like this

temp='{ "1": { "my_name": "one" }, "2": { "my_name": "two" } }'

Now I need to get the value of my_name for both other entries

I have tried something like this

echo $temp | jq '.1' //out put 0.1
I was assuming to get { "my_name": "one" } 

And similarly to get my_name value I did

echo $temp | jq '.1.my_name' // Its output is giving me error

Can any one please help to identify what is wrong with my syntax and how can I correct it.

Answer 1

Just the number gets interpreted as a float. You need to use it in a context where it is unambiguously a key string.

echo "$temp" | jq '.["1"]["my_name"]'

and

echo "$temp" | jq '.["1"]'

to get the containing dict.

With a sufficiently new jq (I think >= 1.4) you can also say

echo "$temp" | jq '."1".my_name'
