How to loop in Ansible over registerd result and selecting specific node? - ansible

Question

i am registering a result from a specific SQL query:
- name: Output Result
debug:
var: result.query_result[0]
I get a long list that looks like this:
{
"result": {
"changed": true,
"failed": false,
"query_result": [
[
{
"C": "",
"CHID": "",
"DESCRIPTION": "",
"EXPECTED_VALUE": "",
"HOST": "",
"SAP_NOTE": "",
"VALUE": ""
},
{
"C": "",
"CHID": "M0005",
"DESCRIPTION": "Generated with",
"EXPECTED_VALUE": "",
"HOST": "",
"SAP_NOTE": "1969700",
"VALUE": "SQL: \\HANA_Configuration_MiniChecks\\\"\""
}
]
],
"rc": 0,
"stderr": "",
"stderr_lines": []
}
}
How can I output only this part if he exists:
{
"C": "",
"CHID": "M0005",
"DESCRIPTION": "Generated with",
"EXPECTED_VALUE": "",
"HOST": "",
"SAP_NOTE": "1969700",
"VALUE": "SQL: \\HANA_Configuration_MiniChecks\\\"\""
}
The location of the above node can change, so i can't specifically target it.

Answer 1

you can use json_query to filter the item that has key/value: "CHID": "M0005"
full playbook example to demonstrate:
---
- hosts: localhost
gather_facts: false
vars:
query_result:
- C: ''
CHID: ''
DESCRIPTION: ''
EXPECTED_VALUE: ''
HOST: ''
SAP_NOTE: ''
VALUE: ''
- C: ''
CHID: M0005
DESCRIPTION: Generated with
EXPECTED_VALUE: ''
HOST: ''
SAP_NOTE: '1969700'
VALUE: 'SQL: \HANA_Configuration_MiniChecks\""'
- C: ''
CHID: 22M00051231
DESCRIPTION: Generated with2121
EXPECTED_VALUE: ''
HOST: ''
SAP_NOTE: '1969700444'
VALUE: '444SQL: \HANA_Configuration_MiniChecks\""'
tasks:
- set_fact:
filtered_item: "{{ query_result | json_query('[?CHID == `M0005`]') }}"
- debug:
var: filtered_item
in your case, the json_query should look like:
- set_fact:
filtered_item: "{{ result.query_result | json_query('[?CHID == `M0005`]') }}"
Please note that if the list may have multiple items matching the condition, they will all be added to the filtered_item. To make sure you get only the first, you can pass the result to first:
- set_fact:
filtered_item: "{{ query_result | json_query('[?CHID == `M0005`]') | first }}"
