I have an SQL server with the following layout
Table ( id int
title varchar(40),
start Date(),
end Date(),
allDay bool,
username varchar(40)
);
I have gotten the following code from this blog to create a JSON object from the data I wish to use, however his data is stored differently. How do I create the same object, extracted from my database?
I am guessing I need to make the file a .cshtml file rather than a .js file and use this :
@{
var db = Database.Open("events");
var selectQueryString = "SELECT * FROM events";
}
@foreach(var row in db.Query(selectQueryString)){ }
But how do I adapt this code to produce the same JSON object?
Here is the relevant code from the blog, my attempt is below :
public JsonResult GetEvents(double start, double end)
{
var userName = Session["UserName"] as string;
if(string.IsNullOrEmpty(userName))
{
return null;
}
var fromDate = ConvertFromUnixTimestamp(start);
var toDate = ConvertFromUnixTimestamp(end);
var rep = Resolver.Resolve<IEventRepository>();
var events = rep.ListEventsForUser(userName,fromDate,toDate);
var eventList = from e in events
select new {
id = e.Id,
title = e.Title,
start = e.FromDate.ToString("s"),
end = e.ToDate.ToString("s"),
allDay = false
};
var rows = eventList.ToArray();
return Json(rows,JsonRequestBehavior.AllowGet);
}
Edit :
I am now working with the following .cshtml code for the GetEvents mand, but it will not work. Does anybody have any ideas ?
@{
var origin = new DateTime(1970, 1, 1, 0, 0, 0, 0);
var fromDate = origin.AddSeconds((Request["start"]));
var toDate = origin.AddSeconds(Request["end"]);
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";
}

Reset to default 5There 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
DECLARE @listCol VARCHAR(2000)
DECLARE @query VARCHAR(4000)
SELECT @listCol = STUFF(( SELECT distinct '], [' + [PSize]
FROM Pattern
FOR
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
