How does the QueryString work? When you insert a new review, how does this querystring works? What does ([Id] = @Id) got to do with insert?

The QueryString in ASP.NET reads information from the URL. So with a URL like this:

Something.aspx?ID=123

and code like this:

Request.QueryString["ID"]

would give you 123.

The id = @id part is used to assign a value to the id field coming from a parameter called id, prefixed with the @ symbol to indicate it's coming from a paramater.

Hope his helps, but if not, please ask specific questions and provide a copy of the code you're asking questions about.

Cheers,

Imar
