Can 2 jq commands be combined to extract specific values from JSON data?

I want to combine below mentioned 2 jq commands to work together in a single jq command.

Command 1:

jq -r '.objects[] | "(.name),(.uid),(.type),(."ipv4-address"),(."nat-settings"."ipv4-address"),(."nat-settings"."ipv6-address"),(."nat-settings"."install-on"),(."nat-settings".method)"'

Command 2:

jq -r '.objects[].groups[].name'

I’m able to get output of commands when executed separately but I’m not getting any output after combining both.

Combined command that I used:

jq -r '.objects[] | "(.name),(.uid),(.type),(.["ipv4-address"]),(.["nat-settings"]["ipv4-address"]),(.["nat-settings"]["ipv6-address"]),(.["nat-settings"]["install-on"]),(.["nat-settings"]["method"]),(.groups[]?.name)"'

Please help me correct this command.

You can add (.groups[].name) in the string literal

Syntax example with reduced field to keep it simple

.objects[] | "(.name),(.uid),(.groups[].name)"

"BL_2.2.2.2,network11111"
"BL_2.2.2.2,workrrorxzdg"

With all fields (from OP):

.objects[] | "(.name),(.uid),(.type),(."ipv4-address"),(."nat-settings"."ipv4-address"),(."nat-settings"."ipv6-address"),(."nat-settings"."install-on"),(."nat-settings".method),(.groups[].name)"

"BL_2.2.2.2,11c758bf-15d7-47ba-af1a-200ffa171587,host,2.2.2.2,66.66.66.66,,All,hide,network11111"
"BL_2.2.2.2,11c758bf-15d7-47ba-af1a-200ffa171587,host,2.2.2.2,66.66.66.66,,All,hide,workrrorxzdg"

OP’s comment, output as a single line:
Use join() in the string literal:

.objects[] | "(.name),(.uid),(.type),(."ipv4-address"),(."nat-settings"."ipv4-address"),(."nat-settings"."ipv6-address"),(."nat-settings"."install-on"),(."nat-settings".method),([ .groups[].name ] | join(","))"

But removing the string literal and using join() or @csv on an array holding your field makes this a lot easier:

.objects[] | [ .name, .uid, .type, .groups[].name ] | join(",")

You can also store it in a variable:

.objects[] | .groups[].name as $groupsname | [ .name, .uid, .type,
  ."ipv4-address", ."nat-settings"."ipv4-address", ."nat-settings"."ipv6-address",
  ."nat-settings"."install-on", ."nat-settings".method, $groupsname
] | join(",")  # or @csv

BL_2.2.2.2,11c758bf-15d7-47ba-af1a-200ffa171587,host,2.2.2.2,66.66.66.66,,All,hide,network11111
BL_2.2.2.2,11c758bf-15d7-47ba-af1a-200ffa171587,host,2.2.2.2,66.66.66.66,,All,hide,workrrorxzdg

Demo

The edited output is even simpler: Just iterate over the array:

.objects[] | [ .name, .uid, .type,
  ."ipv4-address", ."nat-settings"."ipv4-address", ."nat-settings"."ipv6-address",
  ."nat-settings"."install-on", ."nat-settings".method, .groups[].name
] | join(",")  # or @csv

BL_2.2.2.2,11c758bf-15d7-47ba-af1a-200ffa171587,host,2.2.2.2,66.66.66.66,,All,hide,network11111,workrrorxzdg
