So, Is it possibe to that? Where I have parameter p1 which is a colection of strings and I pass it like an array or a list like p1(0) , p1(1) . and so on? Are there any alternatives to that? I cannot use a where clause here, I think, because I am using JSON post as query, so I will pass all the values of the parameter. IF we can do that, how do I load that parameter? BY an input control?
