Declaring a variable with json content

Json content:

[
  {
    "name": "Flavio",
    "code": "FLA-1",
    "isDeleted": false
  },
  {
    "name": "Contoso",
    "code": "CON-1",
    "isDeleted": true
  }
]

-- SET JSON CONTENT TO A VARIABLE (@JSON)...
DECLARE @json NVARCHAR(max) = N'[
    {
      "name": "Flavio",
      "code": "FLA-1",
      "isDeleted": false
    },
    {
      "name": "Contoso",
      "code": "CON-1",
      "isDeleted": true
    }
  ]';

Fill a temp table with json content

-- FILL #TEMP TABLE WITH JSON CONTENT...
SELECT firstName, code, IIF(isDeleted = 1, 0, 1) as active 
    INTO #temp
    FROM OPENJSON(@json)
WITH  (
        firstName   VARCHAR(50) '$.name', 
        code        VARCHAR(10) '$.code',
        isDeleted   BIT         '$.isDeleted'
    );

Show items from temp table

-- SHOW ITEMS FROM #TEMP TABLE
SELECT * FROM #temp;

If you need to drop temp table

-- REMOVE A #TEMP TABLE...
DROP TABLE #temp;
