How to set default value

 My code like below:

DetailView1.datasource = New Query("table").Where("ID", id).ExecuteReader();      // id from session

My question is: How can I set the default value for id?      id = 1

Thank.

I don't really understand the question, but does this help?

DetailView1.datasource = New Query("table").Where("ID", (id > 1 ? id : 1)).ExecuteReader();
