Question

Please can somebody help me convert this MySQL query in to Entity Framework?
Im using that in an ASP .NET project but I only know how to do basic queries in Entity Framework. This seems way too complicated and I cant find a working solution since many hours now…

 $rs = mysql_query("SELECT barcode,latitude,longitude,date_time,location_name 
                    FROM sDetails
                    JOIN users on (users.id=sDetails.UserId)  
                    WHERE  (latitude and longitude is not null) 
                       and (latitude <> 100000 and longitude <> 100000)
               and id='$UserId'
            ORDER BY date_time desc");

Assuming you have generated an Entity Framework model from the database you should be able to do something like (c# example):

 var q = context.Details.Where( d => d.UserId = "$UserID" ).
             Where( d => d.latitude.HasValue && d.latitude != 100000 && .. etc ).
             OrderByDescending( d => d.date_time ).
             Select( d => new {d.barcode, d.latitude, d.longitude, etc ... };

I’m not sure why you have a join since you’re not selecting anything from the users tables.
