Question

I’m trying to export certain fields from the query below to a Text file. The problem I’m facing is that only one record is showing up in the text file when I export it, I also want to append none query results to this text file.

Also, some of the lines don’t need to be repeated,

    odbccon.Open();
    OdbcCommand getcartons = new OdbcCommand("select * from wm242basd.chcart00 where chldno = '0010585567'", odbccon);
    OdbcDataAdapter adp = new OdbcDataAdapter(getcartons);
    OdbcDataReader odbcr = getcartons.ExecuteReader();
    while (odbcr.Read())
    {
        cartonnumber = odbcr["chcasn"].ToString() + "                 ";
        storenumber = odbcr["chstor"].ToString() + "  ";
        weightlbs = odbcr["chacwt"].ToString();
    }

Answer 1

your while loop is setting the three variables repeatedly, but once the loop is done, each variable only has one value.

thus, the values from the last record, and only those values, are used when writing to the file.

move the end brace of the while loop so it includes all code that you wish to be executed for each data record, but make sure that the file is opened before and closed after the while loop
