Hi,

I used following code to get oracle table column data to drop down list

connection.Open();
string qu = "select NAME from dbinfo where status !=DROPED ; order by NAME";
drpSID.DataSource = GetSQLData(qu);
connection.Close();

but it dosen't work. The GetSQLData function is as follows:

public DataTable GetSQLData(string query)
{
  try
  {
    DataTable dt = new DataTable();
    if (connection.State == ConnectionState.Closed)
      connection.Open();
    command.Connection = connection;
    command.CommandType = CommandType.Text;
    command.CommandText = query;
    OracleDataAdapter da = new OracleDataAdapter(command);
    da.Fill(dt);
    return dt;
  }
  catch (Exception)
  {
    return null;
  }
}

I don't know what I have to do.

Solution 1

Remove the ";" before order by clause in your query

Hi Kasunmit,

shouldn't the code look more like:

string qu = "select NAME from dbinfo where status <> 'DROPED' order by NAME";

The relational operator for not equal to is "<>", that's how I'd use it.
And if status is a character bases field single quotes around the string literal are in order.

Hope that helps

Cheers

Manfred

Does the DataTable returned by GetSQLData() contain any records? I'd advise you to set a breakpoint at the start of the GetSQLData method and step through the code to see what happens. Maybe an exception occurs and null is returned. What exactly do you mean by "It doesn't work"?
