Hello,

I have SQL query that gives me a single data like below:

SELECT Count(Activity)
FROM [Activities]
where Activity = 7

It gives me 57 and I would like 57 to be displayed on my windows form using a label. How could I display that SQL data in my windows form using a label?

Solution 1

Using the SqlCommand object and the SqlConnection class.

Something similar to:

C#

SqlConnection conn = new SqlConnection();
... set conn properties
SqlCommand cmd = new SqlCommand();
... set cmd properties
cmd.CommandText = "SELECT Count(Activity) FROM [Activities] where Activity = 7
Object temp = cmd.ExecuteScalar();
label.Text = temp.ToString();

And add try,catch, etc.

Try this:

SqlConnection myConn = new SqlConnection("your connection");
                       myConn.Open();
                       SqlCommand myCommand = myConn.CreateCommand();

                           myCommand.CommandText = "Select Count(Activity)From [Activities] Where Activity = 7";
                           myCommand.CommandType = CommandType.Text;
                           SqlDataReader reader = myCommand.ExecuteReader();
                           DataTable dt2 = new DataTable();
                           dt2.Load(reader);

                           if (dt2.Rows.Count != 0)
                           {
                               yourLabel.Text = dt2[0].ToString();
                           }
