    <p>I tested the query on SQL Server and it works, but not on C#. The error messages point towards the storing mechanism for the variables returned by my query, but I am thinking it is probably the query itself that is the issue. </p> <p>In Delphi, there is a way to debug query statements (<code>showMessage</code> statement). </p> <p>For example:-</p> <pre><code>DMS.ADOQuery1.SQL.Clear; DMS.ADOQuery1.SQL.Add('select FIRSTNM, LASTNM, STREET, STREET2, CITY, STATE, ZIP, MEMBERKEY, MEMBID, BIRTH' + ' from MEMBER' + ' where MEMBID = ''' + Mem_ID + '''' ); showmessage(DMS.ADOQuery1.SQL[0]); </code></pre> <p><em><strong>Is there a way to do something similar in C# ? Could anyone take a look and let me know why the SQL query doesn't work in ASP.net but works in SQL Server?</em></strong></p> <pre><code>// initialize string [] HPCODE = new string[20] ; string [] OPFROMDT = new string [20] ; string [] OPTHRUDT = new string [20] ; // Second SQL Query to find out eligibility information about the requested Member. // SqlConnection Connection1 = new SqlConnection(DBConnect.SqlServerConnection); String strSQL1 = "SELECT MEMBER, HPCODE, convert(varchar, OPFROMDT, 101) as OPFROMDT, convert(varchar, OPTHRUDT, 101) as OPTHRUDT FROM [main].[dbo].[MEMBER] INNER JOIN [main].[dbo].[MEMBHP] ON MEMBER.MEMBERKEY = MEMBHP.MEMBERKEY and opthrudt &gt;= opfromdt INNER JOIN [main].[dbo].[HPCONTRACT] ON MEMBHP.HPCODEKEY = HPCONTRACT.HPCODEKEY INNER JOIN [main].[dbo].[LOB] ON HPCONTRACT.LOB_KEY = LOB.LOB_KEY where MembID = @memID"; SqlCommand command1 = new SqlCommand(strSQL1, Connection1); //command1.Parameters.AddWithValue("@memID", memID); // SQL reader variable is set. SqlDataReader Dr1; // Connection is explicitly opened. Connection1.Open(); // Reader is executed.

Dr1.Close(); </code></pre> <p><strong>Error:</strong></p> <blockquote> <p><em>Index out of range Exception unhandled by user code:=HPCODe</em> <br> <br></p> </blockquote> <p><strong>NOTE:-</strong> <br> <code>Parameters.AddwithValue</code> is uncommented because it is predefined in my previous part of the code.

    1. COHoly horizontal scrolling, Batman! What doesn't work? What is the error message? And do you really mean to have `//command.Parameters.AddWithValue("@memID", memID);` commented out?

    3. COI actually have the Parameters.AddWithValue predefined in a previous SQL Query, so that is why I have it commented out.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
