This article will show you the steps involved in connecting Tableau to a JSON file with an example. The code below will show you the sql query we used to generate the JSON file.
SELECT Cat.[EnglishProductCategoryName] AS Category,
SubCat.[EnglishProductSubcategoryName] AS SubCategory,
Prod.EnglishProductName AS ProductName, Prod.Color,
SUM(Fact.OrderQuantity) AS Orders, SUM(Fact.TotalProductCost) AS ProductCost,
SUM(Fact.SalesAmount) AS Sales, SUM(Fact.TaxAmt) AS Tax
FROM FactInternetSales AS Fact
INNER JOIN DimProduct AS Prod ON Fact.ProductKey = Prod.ProductKey
INNER JOIN DimProductSubcategory AS SubCat ON Prod.ProductSubcategoryKey = SubCat.ProductSubcategoryKey
INNER JOIN DimProductCategory AS Cat ON SubCat.ProductCategoryKey = Cat.ProductCategoryKey
GROUP BY Cat.[EnglishProductCategoryName], SubCat.[EnglishProductSubcategoryName],
Prod.EnglishProductName, Prod.Color
FOR JSON PATH,
INCLUDE_NULL_VALUES
