C#

Dear All.

I developed a POS system to sell goods in a supermarket using Visual studio C# and crystal report for receipt generation and reports. My problem is this, when i try to print daily sales, it prints all sales as it is in the database all i want is to sum up of a particular item sold together e.g if i sold 10 bottles of coke to different customers its showing it one by one by sales but i want it to sum it up to be 10 instead of listing it one by one as it is sold.

What I have tried:

I dont know how to go about it

How can i use this in crystal report?

Crystal Report generates reports from data queries, just edit the query for your report.

I tried to write this line of query but i get and error saying incorrect syntax near the key word 'where'

public DataSet Dailysales(string date)
{

DataSet ds = new DataSet();
string sql = "select Itemname, SUM(QntSold) from POS GROUP BY Itemname where Date ='" + Convert.ToDateTime(date) + "'";
SqlDataAdapter dadbt = new SqlDataAdapter(sql, mycon.Opencon());
dadbt.Fill(ds);
dadbt.Dispose();
return ds;

}
