If an integer dividend is divided by an integer divisor, the result is an integer that has any fractional part of the result truncated.

Examples

The following example uses the division arithmetic operator to calculate the sales target per month for the sales people at Adventure Works Cycles.

-- Uses AdventureWorks 
 
SELECT s.BusinessEntityID AS SalesPersonID, FirstName, LastName, SalesQuota, SalesQuota/12 AS 'Sales Target Per Month' 
FROM Sales.SalesPerson AS s 
JOIN HumanResources.Employee AS e 
 ON s.BusinessEntityID = e.BusinessEntityID 
JOIN Person.Person AS p 
 ON e.BusinessEntityID = p.BusinessEntityID; 

Here is a partial result set.

 
SalesPersonID FirstName LastName SalesQuota Sales Target Per Month 
------------- ------------ ----------------- ----------- ------------------ 
274 Stephen Jiang NULL NULL 
275 Michael Blythe 300000.00 25000.00 
276 Linda Mitchell 250000.00 20833.3333
