Snowflake SQL - Dynamically turning irregular JSON data into "CASE WHEN" SQL clause - sql

Question

I feel compelled to specify from the very beginning that I am a total newbie to Snowflake and the idea of JSON data tables.
This being said I find myself faced with the following challenge:
I have a Snowflake table called ANIMALS which holds a JSON object with a semi irregular structure on the conditions part:
{
"animals": [
{
"name": "TIGER",
"id": 101,
"conditions": {
"and": [
{
"operator": "=",
"attribute": "ANIMAL_FAMILY",
"value": "feline"
},
{
"operator": "IN",
"attribute": "SUBSPECIES",
"value": ["Bengal", "Sumatran", "Siberian"]
},
{
"operator": "=",
"attribute": "ORDER",
"value": "carnivorous"
}
]
}
},
{
"name": "CAT",
"id": 102,
"conditions": {
"and": [
{
"operator": "=",
"attribute": "ANIMAL_FAMILY",
"value": "feline"
},
{
"or": [
{
"operator": "IN",
"attribute": "SUBSPECIES",
"value": ["Abyssinian", "Manx", "Siamese", "Sphynx"]
},
{
"operator": "=",
"attribute": "ENVIRONMENT",
"value": "domestic"
}
]
}
]
}
},
{
"name": "DOG",
"id": 103,
"conditions": {
"or": [
{
"operator": "=",
"attribute": "IS_MOST_BELOVED_PET",
"value": true
},
{
"and": [
{
"operator": "=",
"attribute": "ANIMAL_FAMILY",
"value": "canine"
},
{
"operator": "=",
"attribute": "ENVIRONMENT",
"value": "domestic"
}
]
},
{
"and": [
{
"operator": "=",
"attribute": "ENVIRONMENT",
"value": "domestic"
},
{
"or": [
{
"operator": "C",
"attribute": "ANIMAL_FAMILY",
"value": "%feline%"
},
{
"operator": "IN",
"attribute": "SUBSPECIES",
"value": ["Akita", "Beagle", "Border Collie", "Cane Corso", "Chihuahua"]
}
]
}
]
},
]
}
},
{
"name": "HORSE",
"id": 104,
"conditions": {
"operator": "=",
"attribute": "ANIMAL_FAMILY",
"value": "equine"
}
}
]
}
There is absolutely no limit for the degree of nesting the AND and OR operators, which unfortunately makes the conditions very irregular.
Given this JSON I need to dynamically generate a CASE WHEN [condition] THEN [value] clause which will look like this:
CASE WHEN ((ANIMAL_FAMILY = 'feline') AND (SUBSPECIES IN ('Bengal', 'Sumatran', 'Siberian')) AND (ORDER = 'carnivorous')) THEN 'TIGER'
WHEN ((ANIMAL_FAMILY = 'feline') AND ((SUBSPECIES IN ('Abyssinian', 'Manx', 'Siamese', 'Sphynx') OR (ENVIRONMENT = 'domestic')))) THEN 'CAT'
WHEN ((IS_MOST_BELOVED_PET = TRUE) OR ((ANIMAL_FAMILY = 'canine') AND (ENVIRONMENT = 'domestic')) OR ((ENVIRONMENT = 'domestic') AND ((ANIMAL_FAMILY NOT LIKE %feline%) OR (SUBSPECIES IN ('Akita', 'Beagle', 'Border Collie', 'Cane Corso', 'Chihuahua'))))) THEN 'DOG'
WHEN ANIMAL_FAMILY = 'equine' THEN 'HORSE'
END AS animal
Is this doable solely relying on Snowflake queries and no other third-party programming languages?
Any hints and pointers would be greatly appreciated.
Thank you in advance for your replies.
