    <p>I'm trying to do a very simple username and password validation against a table called users (containinig an <code>id(int) username(nchar(10)</code>) and <code>password(char(32)</code>) using Razor but I'm encountering this error:</p> <pre><code>Operator '==' cannot be applied to operands of type 'WebMatrix.Data.DynamicRecord' and 'HasherMD5Main' </code></pre> <p>I created a .cs class that does an md5 hash (<code>HasherMD5Main</code>) which returns the value passed as a string (please no comments on security, this is not going into any production environments) and I'm hashing the entered password and then doing a lookup in the db.</p> <h2>Code</h2> <pre><code>@{// Initialize page var enteredusername = ""; var enteredpassword = ""; var ErrorMessage = ""; // If this is a POST request, validate and process data if( IsPost ) { enteredusername = Request.Form["enteredusername"]; enteredpassword = Request.Form["enteredpassword"]; var hash = new HasherMD5Main( enteredpassword ); if( enteredusername.IsEmpty() || enteredpassword.IsEmpty() ) { ErrorMessage = "You must specify a username and password."; } else { var db = Database.Open( "MyConnectionString" ); var passwordquery = db.QuerySingle( "SELECT password FROM users WHERE username = @0", enteredusername ); if( passwordquery == hash ) { Response.Redirect( "/Success" ); } else { Response.Redirect( "/Failure" ); } } } } @if( ErrorMessage != "" ) { &lt;p&gt;@ErrorMessage&lt;/p&gt; &lt;p&gt;Please correct the errors and try again.&lt;/p&gt; } &lt;form method="post" action=""&gt; &lt;fieldset&gt; &lt;legend&gt;Log In to Your Account&lt;/legend&gt; &lt;ol&gt; &lt;li&gt; &lt;label&gt;Username:&lt;/label&gt; &lt;input type="text" id="enteredusername" name="enteredusername" /&gt; &lt;/li&gt; &lt;li&gt; &lt;label&gt;Password:&lt;/label&gt; &lt;input type="password" id="enteredpassword" name="enteredpassword" /&gt; &lt;/li&gt; &lt;li&gt; &lt;p&gt; &lt;input type="submit" value="login" /&gt;&lt;/p&gt; &lt;/li&gt; &lt;/ol&gt; &lt;/fieldset&gt; &lt;/form&gt; </code></pre> <p>Any ideas on how I can simply validate if the hashed password my app comes up with matches the hash stored in the db?</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.
