Dear All,

I have written a code to display some data in a DataGridView. but it shows duplicate values. here is the code,

public void showEvents()
            cmd2 = new MySqlCommand();
            String cmdString2 = "SELECT d.DId, d.Date,d.Time,d.Temp, d.DLane, d.DVentilation, d.DRemarks FROM date d, container c, Plugoff p where c.GKId=d.GKId  AND c.ContainerNo like ('" + txtContNo.Text + "%') AND c.GKId = ('" + txtUsed.Text + "') ";
            adp = new MySqlDataAdapter(cmdString2, con);
            ds = new DataSet();
            adp.Fill(ds, "cont");
            dataGridView1.DataSource = ds.Tables["cont"];

please someone show me the issue soon ???

Q: You sure that the query is returning correct set of result?

1 solution

You are joining three tables but you where clause contains only one join between them.
Remove Plugoff p from your query and try again. I don't think you are using any values from it anywhere as it is anyway.
