Hello,
Am new to programming, i build an application for a store in visual studio using c# and crystal report for report generation. but i have a problem withe the report, i have a query that i use to fetch data from my sql database and display it on my crystal report but some data field are not showing. but if i write the query without using the group by it will show. below is the query

C#

"select Itemname, SUM(QntSold), SUM(TotalAmnt) from POS  where Date ='" + Convert.ToDateTime(date) + "'GROUP BY Itemname";

with the above query it will only show the group itemnames and will not show the other two table fields which are QntySoild and TotalAmnt. But if i write this other query it will show all the table fields but will not group the itemname, below is the other query that display all but not in group format.

C#

"select * from POS where date ='" + Convert.ToDateTime(date) + "'";

Plz is anything am doing wrong that is not making it to show other fields when it is been grouped because i want it to be grouped together
Thank you

What I have tried:

"select Itemname, SUM(QntSold), SUM(TotalAmnt) from POS where Date ='" + Convert.ToDateTime(date) + "'GROUP BY Itemname";

Solution 1

When you apply aggregate functions like SUM() you lose the column name. So you need to give it a name just like the non-aggregated result columns.

try

SQL

select Itemname, SUM(QntSold) AS QntSold, SUM(TotalAmnt) as TotalAmnt from POS where Date ='" + Convert.ToDateTime(date) + "'GROUP BY Itemname";
