I have a Linq statement to retrieve data into my JAVASCRIPT table. What i want to do is display who the campaign was archived by. I need to join it to my MSCDB.Tbl_Users onto the Campaign table. Could anyone try give me some help with this? I am fairly new to LINQ.
MSCDatabaseDataContext MSCDB = new MSCDatabaseDataContext();
var q = from row in MSCDB.Tbl_Campaigns
where row.CampaignStatus == 4
select new ArchiveReport
{
CampaignId = row.CampaignId,
CampaignName = row.CampaignName,
CampaignDescription = row.CampaignDescription,
CurrentStatus = row.EndDate >= DateTime.Now && row.StartDate <= DateTime.Now ? "Active" : row.StartDate >= DateTime.Now ? "Pending" : row.CampaignStatus == 4 ? "Archived" : "Closed",
CampaignStartDatesS = Convert.ToDateTime(row.StartDate).Date + " - " + Convert.ToDateTime(row.EndDate).Date,
Discount = Convert.ToInt32(row.Discount),
Target = Convert.ToInt32(row.Target),
Uptake = Convert.ToInt32(row.Uptake),
DateArchived = Convert.ToDateTime(row.DateArchived),
ArchivedBy = Convert.ToInt32(row.ArchivedBy)
};
I'm not sure how you db structure looks like but if Tbl_Users
have CampaignId
you should do it like this:
MSCDatabaseDataContext MSCDB = new MSCDatabaseDataContext();
var q = from row in MSCDB.Tbl_Campaigns
//here is your join
join usr in MSCDB.Tbl_Users on row.CampaignId equals usr.CampaignId
//-------------------------
where row.CampaignStatus == 4
select new ArchiveReport
{
//Here how you can jet values from user table
UserName = usr.Name,
//-------------------------
CampaignId = row.CampaignId,
CampaignName = row.CampaignName,
CampaignDescription = row.CampaignDescription,
CurrentStatus = row.EndDate >= DateTime.Now && row.StartDate <= DateTime.Now ? "Active" : row.StartDate >= DateTime.Now ? "Pending" : row.CampaignStatus == 4 ? "Archived" : "Closed",
CampaignStartDatesS = Convert.ToDateTime(row.StartDate).Date + " - " + Convert.ToDateTime(row.EndDate).Date,
Discount = Convert.ToInt32(row.Discount),
Target = Convert.ToInt32(row.Target),
Uptake = Convert.ToInt32(row.Uptake),
DateArchived = Convert.ToDateTime(row.DateArchived),
ArchivedBy = Convert.ToInt32(row.ArchivedBy)
};
Sample code is
var q= from row in MSCDB.Tbl_Campaigns
join user in MSCDB.Tbl_Users
on row.UserId equals user.ID
select row;
