I have this query but I need to add a where clause that uses 'Contains()' so I can check the db for a list of accountIDs, the reason I need to do it this way is because I have to first check if there are any accountID's and if there are it must execute the 'Contains()' in the where clause but the compiler complains if I try do it this way but given what the method has to do I can't figure out another way to do it given the fact that there are so many tables joined in the query.
My code:
bool UseAcc = false;
if (accountIds != null && accountIds.Count > 0)
{
UseAcc = true;
}
var query = (from i in db.Incidents
join s in db.Sites on i.SiteID equals s.SiteID
join a in db.Accounts on i.AccountID equals a.AccountID
join st in db.Status on i.StatusID equals st.StatusID
join currentUser in db.Users on i.CurrentAssignedUser equals currentUser.UserID
join loggedByUser in db.Users on i.LoggedByUser equals loggedByUser.UserID
join createdByUser in db.Users on i.CreatedByUser equals createdByUser.UserID
join l in db.Locations on i.Location equals l.LocationID into locList
from loc in locList.DefaultIfEmpty()
join q in db.QuestionCategories on i.QuestionCategoryID equals q.QuestionCategoryID
join ia in db.IncidentActions on i.IncidentID equals ia.IncidentID into iaList
from actions in iaList.DefaultIfEmpty()
//If 'UseAcc' gets set to true then execute the contains section of the or statement
where (i.Active == true) &&
(UseAcc = false || a => accountIds.Contains(a.AccountID))
select new
{
Title = i.Title,
IncidentID = i.IncidentID,
StatusName = st.StatusName,
StatusID = i.StatusID,
ReferenceNumber = i.ReferenceNo,
AccountName = a.AccountName,
AccountID = i.AccountID,
SiteName = s.SiteName,
SiteID = i.SiteID,
LocationName = loc.LocationName,
LocationID = i.Location,
CatName = q.QuestionCategoryName,
CatID = i.QuestionCategoryID,
CurrentAssignedUser = currentUser.FirstName + " " + currentUser.LastName,
AssignedUserID = i.CurrentAssignedUser,
CreatedByUser = createdByUser.FirstName + " " + createdByUser.LastName,
DateCreated = i.LoggedDate,
DepartmentID = i.DepartmentID,
Logger = loggedByUser.FirstName + " " + loggedByUser.LastName,
LoggedBy = i.LoggedByUser,
EscalationCount = i.EscalationCount)
});
I would paste the whole method but its really big.
I have looked at examples online but they can't work either because alot of them use an AsQueryable with a single table and this query has many tables joined.
Please Help.
var accounts = db.Accounts.AsQueryable();
if (accountIds != null && accountIds.Count > 0)
{
accounts = accounts.Where(a => accountIds.Contains(a.AccountID));
}
var query = (from i in db.Incidents
join s in db.Sites on i.SiteID equals s.SiteID
join a in accounts on i.AccountID equals a.AccountID
join st in db.Status on i.StatusID equals st.StatusID
join currentUser in db.Users on i.CurrentAssignedUser equals currentUser.UserID
join loggedByUser in db.Users on i.LoggedByUser equals loggedByUser.UserID
join createdByUser in db.Users on i.CreatedByUser equals createdByUser.UserID
join l in db.Locations on i.Location equals l.LocationID into locList
from loc in locList.DefaultIfEmpty()
join q in db.QuestionCategories on i.QuestionCategoryID equals q.QuestionCategoryID
join ia in db.IncidentActions on i.IncidentID equals ia.IncidentID into iaList
from actions in iaList.DefaultIfEmpty()
select new
{
Title = i.Title,
IncidentID = i.IncidentID,
StatusName = st.StatusName,
StatusID = i.StatusID,
ReferenceNumber = i.ReferenceNo,
AccountName = a.AccountName,
AccountID = i.AccountID,
SiteName = s.SiteName,
SiteID = i.SiteID,
LocationName = loc.LocationName,
LocationID = i.Location,
CatName = q.QuestionCategoryName,
CatID = i.QuestionCategoryID,
CurrentAssignedUser = currentUser.FirstName + " " + currentUser.LastName,
AssignedUserID = i.CurrentAssignedUser,
CreatedByUser = createdByUser.FirstName + " " + createdByUser.LastName,
DateCreated = i.LoggedDate,
DepartmentID = i.DepartmentID,
Logger = loggedByUser.FirstName + " " + loggedByUser.LastName,
LoggedBy = i.LoggedByUser,
EscalationCount = i.EscalationCount)
});

Here I want to join the out put of the first query(one column) to the result of the 2nd query to get a one result set. How can I merge them.(CONCAT doesn't work as required. eg: var query2 = query.concat(query1);)
var query = (from PP in _db.paymentPlans
join APP in _db.Applications on PP.applicationID equals APP.ApplicationId
join C in _db.Courses on APP.courseID equals C.courseID
where PP.active == true && APP.agentID == agentID
orderby C.courseID ascending
group new {C,PP} by new {C.courseID} into totalRecievable
select new PdPpAppCourseModel
{
courseID = totalRecievable.Key.courseID,
totalAmount = totalRecievable.Sum(x => x.PP.totalAmount)
}).ToList();
var query1=(from PD in _db.paymentDetails
join PP in _db.paymentPlans on PD.paymentPlanID equals PP.paymentPlanID
join APP in _db.Applications on PP.applicationID equals APP.ApplicationId
join C in _db.Courses on APP.courseID equals C.courseID
where PP.active == true && APP.agentID == agentID
orderby C.courseID ascending
group new { C,PD } by new { C.courseID, C.cricosCode, C.courseName } into paymentsCourseWise
select new PdPpAppCourseModel
{
courseID = paymentsCourseWise.Key.courseID,
cricosCode = paymentsCourseWise.Key.cricosCode,
courseName = paymentsCourseWise.Key.courseName,
paidAmount = paymentsCourseWise.Sum(x => x.PD.paidAmount)
}).ToList();
You could join query1 and query like this
var result = (from q1 in query1
join q in query on q1.courseID = q.courseID
select new PdPpAppCourseModel
{
courseID = q1.Key.courseID,
cricosCode = q1.Key.cricosCode,
courseName = q1.Key.courseName,
paidAmount = q1.Sum(x => x.PD.paidAmount),
totalAmount = q.totalAmount
}).ToList();

I want to save each icon path into a variable, from the query bellow , only PathIcon1 has value . The remain path icon are empty
Query
using (CarteringServiceClientDataContext dc = new CarteringServiceClientDataContext())

let r = (from re in dc.GetTable<tblClientReview>()

select re.note).Average()
let i = (from im in dc.GetTable<tblSupplierItem>()

PathIcon4 = i.Skip(3).Take(1).SingleOrDefault(),
PathIcon5 = i.Skip(4).Take(1).SingleOrDefault()

}
A part from PathIcon1, the remaing PathIcon are null
using (CarteringServiceClientDataContext dc = new CarteringServiceClientDataContext())
{
result = (from a in dc.GetTable<tblSupplier>()

PathIcon4 = i.Skip(3).Take(1).SingleOrDefault(),
PathIcon5 = i.Skip(4).Take(1).SingleOrDefault()
}).ToList<SearchResult>();
}
Try this if you are get PathIcon2 value as "test" your problem isn't skip or take. Just i list includes one item. Adn I think so.
Here is a linq query, and the table "Timesheet_Log" has DT_CR Column with type DateTime and I want to get the query with latest DT_CR Date, how is it possible?
var getEmployeeNames = (from emps in reslandentity.EMPLOYEE
join timesheet in reslandentity.TIMESHEET on emps.ID equals timesheet.RES_ID
join weekcal in reslandentity.WEEK_CALENDER on timesheet.WEEK_CAL_ID equals weekcal.ID
join log in reslandentity.TIMESHEET_LOG on timesheet.ID equals log.TIMESHEET_ID
join workflow in reslandentity.TIMESHEET_WORKFLOW on log.WORKFLOW_ID equals workflow.ID
where weekcal.WEEK_START_DT.Month == month
orderby log.DT_CR select new TimesheetModel
{
EMP_ID = emps.ID,
EMPLOYEE_NAME = emps.FIRST_NAME + " " + emps.LAST_NAME,
RES_TYPE = workflow.ORG_RES_TYPE,
EMP_STATUS = workflow.ACTION,
SDate = weekcal.WEEK_START_DT,
EDate = weekcal.WEEK_END_DT,
DT_CR=log.DT_CR
}).Distinct().ToList();
model.GetTimeSheetDetails = getEmployeeNames;
Please Help me to get the Query.
You've not made it clear if you expect just a single result or a list of results (1 per timesheet).
If you just need a single result the answer by lti Tyangi will be fine.
If you need a result per timesheet you could try the following:
var getEmployeeNames = (from emps in reslandentity.EMPLOYEE
join timesheet in reslandentity.TIMESHEET on emps.ID equals timesheet.RES_ID
join weekcal in reslandentity.WEEK_CALENDER on timesheet.WEEK_CAL_ID equals weekcal.ID
join mxLog in (
from lg in reslandentity.TIMESHEET_LOG
group lg by lg.TIMESHEET_ID into lgGrp
select new {lgGrp.Key, DT_CR = lgGrp.Max(x => x.DT_CR)}
) on timesheet.ID equals mxLog.Key
join log in reslandentity.TIMESHEET_LOG on new { a = mxLog.Key, b = mxLog.DT_CR} equals new{ a = log.TIMESHEET_ID, b = log.DT_CR}
join workflow in reslandentity.TIMESHEET_WORKFLOW on log.WORKFLOW_ID equals workflow.ID
where weekcal.WEEK_START_DT.Month == month
orderby log.DT_CR select new TimesheetModel
{
EMP_ID = emps.ID,
EMPLOYEE_NAME = emps.FIRST_NAME + " " + emps.LAST_NAME,
RES_TYPE = workflow.ORG_RES_TYPE,
EMP_STATUS = workflow.ACTION,
SDate = weekcal.WEEK_START_DT,
EDate = weekcal.WEEK_END_DT,
DT_CR=log.DT_CR
}).Distinct().ToList();
model.GetTimeSheetDetails = getEmployeeNames;
here we join onto a grouping of the logs per timesheet to get the maximum date per timesheet, and then join to the logs based on both the id of the timesheet and that date
var getEmployeeNames = (from emps in reslandentity.EMPLOYEE
join timesheet in reslandentity.TIMESHEET on emps.ID equals timesheet.RES_ID
join weekcal in reslandentity.WEEK_CALENDER on timesheet.WEEK_CAL_ID equals weekcal.ID
join log in reslandentity.TIMESHEET_LOG on timesheet.ID equals log.TIMESHEET_ID
join workflow in reslandentity.TIMESHEET_WORKFLOW on log.WORKFLOW_ID equals workflow.ID
where weekcal.WEEK_START_DT.Month == month
//orderby log.DT_CR
select new TimesheetModel
{
EMP_ID = emps.ID,
EMPLOYEE_NAME = emps.FIRST_NAME + " " + emps.LAST_NAME,
RES_TYPE = workflow.ORG_RES_TYPE,
EMP_STATUS = workflow.ACTION,
SDate = weekcal.WEEK_START_DT,
EDate = weekcal.WEEK_END_DT,
DT_CR=log.DT_CR
}).OrderByDescending(x=>x.DT_CR).FirstorDefault();
