ASP.NET SQL statements execution
<p>Couple of days in a row I am trying to master APS.NET authentication process. I am completely confused.</p>

<p>I've created simple website which using Form authentication. ( This is totally magic )
Authentication works well, but have no clue how it works, probably code and SQL statements already injected somewhere deep in framework. But how do I create a custom control?</p>

<p>Lets say I have two categories of users: Member and Moderator. </p>

<p>I want Moderator able to execute <code>Insert</code>, <code>Update</code>, and <code>Delete</code> SQL staments but Member will be restricted for those operations and able to perform <code>Select</code> statement only and only for his records. </p>

<p>Could you guys guide me how can I achieve it using ASP.NET. Thanks!</p>
