SQL Where Column Contains Array of Json

Question

I am trying to query a column that contains an array of json objects.

The array of object looks like this:

[
{
    "TYPE": "car",
    "NAME": "lucy"
},
{
    "TYPE": "bus",
    "NAME": "bob"
},
{
    "TYPE": "car",
    "NAME": "mary"
}
]

I am trying to select if the column contains objects with type = "car" and name = "lucy"

You can use OPENJSON to break out the array into separate rows:

SELECT j.*
FROM YourTable t
CROSS APPLY OPENJSON(t.) WITH (
    [TYPE] varchar(50),
    [NAME] varchar(50)
) j
WHERE j.[TYPE] = 'car' AND j.[NAME] = 'lucy'

Or if you want to just filter the main table based on that, put it inside a WHERE

SELECT t.*
FROM YourTable t
WHERE EXISTS (SELECT 1
    FROM OPENJSON(t.) WITH (
        [TYPE] varchar(50),
        [NAME] varchar(50)
    ) j
    WHERE j.[TYPE] = 'car' AND j.[NAME] = 'lucy'
);
