Hello,

I have the following SELECT statement to retrieve products from the database and show it on a chart

SQL

SELECT DISTINCT productName, SUM(quantity) AS Expr1, orderPeriod 
     FROM WP_analytic WHERE (orderPeriod >= GETDATE() - 30) GROUP BY productName, orderPeriod

I am able to retrieve the product and display however there will be duplicates of a particular product if the orderPeriod is different days. OrderPeriod data type is DateTime.

I want to make it such that for a period of 30 days, it will show accumulated quantity for a particular product within the period without any duplicates on the chart.

Any idea how to achieve this?

It shows duplicate products if the orderPeriod is two different days.

Solution 1

You have duplicates because the orderPeriod field is in the SELECT statement.

Remove this field from both the SELECT and GROUP BY and you should get a total for each product without duplicates.

SQL

SELECT DISTINCT productName, SUM(quantity) AS Expr1
     FROM WP_analytic WHERE (orderPeriod >= GETDATE() - 30) GROUP BY productName
