    <p>Basically just pulling a date out in YYYYMMDD and I can do this fine in a query analyzer but when I try to run this query in C# I keep getting a column not found error it also seems to have a hard time doing concatenation (but that isn't so much of a problem) so a little unsure of what is happening here..I really just want my to_char function to work. Ideas? Thanks!</p> <pre><code> string oradb = "user id=x;password=x;data source=(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)" +"(HOST=x)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=x)));"; OracleConnection conn = new OracleConnection(oradb); conn.Open(); OracleCommand cmd = new OracleCommand(); cmd.Connection = conn; cmd.CommandType = CommandType.Text; cmd.CommandText = "SELECT to_char(ProblemDate, 'yyyymmdd'), data1, data2," +"data4, data5, data6" +" WHERE ( ProblemDate &gt;='03-oct-2011' ) " +"AND ( ProblemDate &lt;= '08-oct-2011' ) AND " +"( data1 in ( '3','5','6' ) )"; OracleDataReader dr = cmd.ExecuteReader(); string fileOut1 = Request.PhysicalApplicationPath; string fileOut = fileOut1 + "Text5.txt"; // Creates the file StreamWriter sw = new StreamWriter(fileOut); if (dr.HasRows) { while (dr.Read()) { string data1= (string)dr["data1"].ToString(); string data2 = (string)dr["data3"].ToString(); string data3 = (string)dr["data4"]; string data4 = (string)dr["data5"].ToString(); string data5 = (string)dr["data6"].ToString(); string ProblemDate = (string)dr["ProblemDate"].ToString(); //remove the comma char[] MyChar = { ',' }; sw.WriteLine(data1.PadRight(10) + data2.PadRight(5) + data3.TrimEnd(MyChar) + "000" + data4 + "000" + data5+ ProblemDate + " " + "N" ); Label1.Text = "File created successfully.&lt;br /&gt;"; Label1.Text += fileOut1; } // Closes the connenction. sw.Close(); conn.Close(); } else { Label1.Text = "No data written."; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
