    <p>To achieve such behavior you should use <code>/k</code> switch to run <code>cmd.exe</code> in interactive mode.</p> <p>The problem is to separate inputs from different commands. To do this you could change the standard prompt using <code>prompt</code> command:</p> <pre><code>prompt --Prompt_C2BCE8F8E2C24403A71CA4B7F7521F5B_F659E9F3F8574A72BE92206596C423D5 </code></pre> <p>So now it is pretty easy to determine the end of command output.</p> <p>Here is the complete code:</p> <pre><code>public static IEnumerable&lt;string&gt; RunCommands(params string[] commands) { var process = new Process { StartInfo = new ProcessStartInfo("cmd") { UseShellExecute = false, RedirectStandardInput = true, RedirectStandardOutput = true, CreateNoWindow = true, Arguments = "/k", } }; process.Start(); const string prompt = "--Prompt_C2BCE8F8E2C24403A71CA4B7F7521F5B_F659E9F3F8574A72BE92206596C423D5 "; // replacing standard prompt in order to determine end of command output process.StandardInput.WriteLine("prompt " + prompt); process.StandardInput.Flush(); process.StandardOutput.ReadLine(); process.StandardOutput.ReadLine(); var result = new List&lt;string&gt;(); try { var commandResult = new StringBuilder(); foreach (var command in commands) { process.StandardInput.WriteLine(command); process.StandardInput.WriteLine(); process.StandardInput.Flush(); process.StandardOutput.ReadLine(); while (true) { var line = process.StandardOutput.ReadLine(); if (line == prompt) // end of command output break; commandResult.AppendLine(line); } result.Add(commandResult.ToString()); commandResult.Clear(); } } finally { process.Kill(); } return result; } </code></pre> <p>It works well but it looks like one big hack.</p> <p>I'd recommend you to use process per command instead.</p>

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).
