I am doing a research project. I have text values like s1, s2, s2, s4 etc in 100s in single column (multiplr rows). Now i want to save these values in a database.

C#

foreach (ListViewItem item in listBox2.Items)
            try
            {
                
               SqlCommand cmd =new System.Data.SqlClient.SqlCommand();
                comd.CommandText= ("INSERT INTO Symptom(s1, s2, s2, s4 )VALUES(@s1,@s2,@s3), s4");
                comd.ExecuteNonQuery();
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message, Application.ProductName, MessageBoxButtons.OK, MessageBoxIcon.Error);

            }
            comd.Connection.Close();
            comd.Dispose();

Can some one help what is the best way to get these strings into database and retrieve them in a single column.
Thanks in advace in millions.

Not sure i quite understand your question.

Do you mean your insert that you provided works but you want to know how to retrieve all columns in "one"?

SELECT s1 + s2 + s2 + s4 AS OneColumnAllResults FROM Symptom

Is that what you want?

Do you want to save those 100 values in one single row of database table ?
or 100 rows where each value in each row

Give me your "Symptom" table structure to understand your problem better ?

Thanks. I have values already in a listbox, single column multiple rows. Now I want to store or save or insert in a table. The problem is let say we have three rats. One held as a control, one exposed to radiation one to chemical. Now we want to see the effects on them after one week, two weeks, 3 weeks etc. These epigenetic effects are let say s1, s2, s3, ... s10 for one rat. I want to store them. I want to add for second week, then third week etc. with date. Now I want to compare them side by side.

The message comes Must declare the scalar variable @s1. Did not work. Any alternate solution.
