Creating A Json Result From Sql Server Database

I have an SQL server with the following layout Table ( id int title varchar(40), start Date(), end Date(), allDay bool, u

Solution 1:

There are no controllers and actions in WebMatrix WebPages. You need to write a separate .cshtml page that will query the database and serve the JSON to the response:

@{
    var db = Database.Open("events");
    var result = db.Query("SELECT * FROM events");
    var data = result.Select(x =>new 
    {
        id = x.id,
        title = x.title,
        start = x.start.ToString("s"),
        end = x.end.ToString("s"),
        allDay = false            
    }).ToArray();

    Json.Write(data, Response.Output);
    Response.ContentType = "application/json";
}

and then in another page in which you want to display the calendar you could configure it:

$(document).ready(function() {             
    $('#calendar').fullCalendar({ 
        theme: true, 
        header: { 
            left: '', 
            center: '', 
            right: '' 
        }, 
        defaultView: 'agendaDay', 
        editable: false, 
        events: '/events.cshtml' 
    }); 
});

---

UPDATE: Here's an example of how you could use parametrized queries:

@{

    var origin = new DateTime(1970, 1, 1, 0, 0, 0, 0);
    var fromDate = origin.AddSeconds(int.Parse(Request["start"]));
    var toDate = origin.AddSeconds(int.Parse(Request["end"]));
    var db = Database.Open("events");
    var sql = "SELECT * FROM events WHERE start >= @0 AND end <= @1";
    var result = db.Query(sql, fromDate, toDate);
    var data = result.Select(x => new 
    {
        id = x.id,
        title = x.title,
        start = x.start.ToString("s"),
        end = x.end.ToString("s"),
        allDay = false            
    }).ToArray();

    Json.Write(data, Response.Output);
    Response.ContentType = "application/json";
}

Now you could query the page like this: /events.cshtml?start=5&end=10

Solution 2:

DECLARE@listColVARCHAR(2000)
DECLARE@queryVARCHAR(4000)

SELECT@listCol= STUFF(( SELECTdistinct'], ['+ [PSize]
                           FROMPatternFOR
                           XML PATH('')
                         ), 1, 2, '') +']'SET@query='SELECT * FROM
      (SELECT PColour as Colour_Size_Matrix, PSize, PCode
            FROM Pattern
            ) src
PIVOT (Count(PCode) FOR PSize
IN ('+@listCol+')) AS pvt'EXECUTE ( @query )

I want the result of this query as JSON
