Convert Number into Words in SQL Server


One of my friend is working in SSRS and he got the requirement to print the total sales amount in the report. To fulfill this requirement we have created a user-defined function to convert the total amount in the words.
Read more about User defined function here:  User define function (UDF) in sql server
Creating function using below script

Function has been created.
Now I am using this function in my sql script.
Here I am using ‘AdventureWorksDW2012’ Database for this demo.

USE [AdventureWorksDW2012]
GO
select pc.EnglishProductCategoryName As Product_Category,
SUM(FIS.SalesAmount) AS Total_Sales_Amount,
dbo.udf_NumberToEnglishWords (SUM(FIS.SalesAmount)) AS Total_Sales_Amount_In_Word,
SUM(FIS.TaxAmt) AS Total_TaxAmt,
dbo.udf_NumberToEnglishWords (SUM(FIS.TaxAmt)) AS Total_TaxAmt_In_Word,
SUM(FIS.Freight) AS Total_Freight,
dbo.udf_NumberToEnglishWords (SUM(FIS.Freight)) AS Total_Freight_In_Word
From FactInternetSales FIS
Inner join DimProduct P
on P.ProductKey=FIS.ProductKey
inner join DimProductSubcategory psc
on p.ProductSubcategoryKey=psc.ProductCategoryKey
Inner Join DimProductCategory pc
on pc.ProductCategoryKey=psc.ProductCategoryKey
Group by pc.EnglishProductCategoryName
UNION ALL
Select  'Total',
SUM(Total_SalesAmount) AS Total_SalesAmount,
dbo.udf_NumberToEnglishWords (SUM(x.Total_SalesAmount)) AS Total_Sales_Amount_In_Word,
SUM(Total_TaxAmt) AS Total_TaxAmt,
dbo.udf_NumberToEnglishWords (SUM(x.Total_TaxAmt)) AS Total_TaxAmt_In_Word,
SUM(Total_Freight) AS Total_Freight,
dbo.udf_NumberToEnglishWords (SUM(x.Total_Freight)) AS Total_Freight_In_Word
FROM (
select pc.EnglishProductCategoryName As Product_Category,
SUM(FIS.SalesAmount) AS Total_SalesAmount,
SUM(FIS.TaxAmt) AS Total_TaxAmt,
SUM(FIS.Freight) AS Total_Freight
From FactInternetSales FIS
Inner join DimProduct P
on P.ProductKey=FIS.ProductKey
inner join DimProductSubcategory psc
on p.ProductSubcategoryKey=psc.ProductCategoryKey
Inner Join DimProductCategory pc
on pc.ProductCategoryKey=psc.ProductCategoryKey
Group by pc.EnglishProductCategoryName
)X

See the output
  
Result in Excel
  
Hope this helps you for the reporting.
