I've been using Subsonic 3.0.0.4 (ActiveRecord approach) for a while, and I recently coded a small page that basically retrieves about 500 records for a given year, and then i just loop through each of them, creating new instances of the Active Record class, just modifying the Period field, and saving each instance in the loop.
The issue is that after executing that page, a LOT of SQL connections are left hanging/open in SQL server (by looking at the sp_who2). Before the page finishes executing, I get the "Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached." error.
The code is the following:

Am I doing it the wrong way? At this point, I am not sure if this is a Subsonic bug or if I need to manually close the connection myself somehow.
I've googled for posts about similar problems when using subsonic, but none have come up. The usual cause for the error I get is not closing the SqlDataReader, but I honestly do not believe Subsonic is not closing it..and Im using the latest version.
Any ideas? Any help is greatly appreciated.
Any time you have a loop on an ORM-based object you have to consider there's probably an N+1 issue. I can't see your model, but I'll bet that in your loop you're executing a number of additional queries.
I know that Save() fires and closes an ExecuteScalar() - this should not leave a connection open. However, if you're fetching related records inside that loop - yeah that could have problems.
So - I would recommend using a profiler of some kind and the debugger to step through your loop - see what queries are made.
Alternatively - this is ripe for using the BatchInsert stuff which would keep everything in a nice, tidy single-connection transaction.

this is my export ui
this is my code:
var wrlist = db.Tbl_WorkRequest.ToList().Where(c => c.WR_Status == wrstatus &&
(wrtype.Length != 0) &&
c.WR_Family == wrfamily &&
wrfamily.Length!=0)
.Select(d => new {
WR_Title = d.WR_Title.ToString(),
WR_Type = d.WR_Type.ToString(),
WR_Family = d.WR_Family.ToString(),
WR_Status = d.WR_Status.ToString(),
WR_LocationAsset = d.WR_LocationAsset.ToString(),
WR_AssetName = d.WR_AssetName.ToString(),
WR_Requestor = d.WR_Requestor.ToString()
});
the problem is if I only choose zone in dropdownlist:family it generates correct list.
but when I choose dropdownlist:family&status it generates nothing.
this is the table:
I would change your code to check each filter criteria and add the appropriate filter, then convert to a list:
var wrq = db.Tbl_WorkRequest.AsQueryable();
if (wrstatus.Length > 0)
wrq = wrq.Where(wr => wr.WR_Status == wrstatus);
if (wrfamily.Length > 0)
wrq = wrq.Where(wr => wr.WR_Family == wrfamily);
var wrlist = wrq.Select(d => new {
WR_Title = d.WR_Title.ToString(),
WR_Type = d.WR_Type.ToString(),
WR_Family = d.WR_Family.ToString(),
WR_Status = d.WR_Status.ToString(),
WR_LocationAsset = d.WR_LocationAsset.ToString(),
WR_AssetName = d.WR_AssetName.ToString(),
WR_Requestor = d.WR_Requestor.ToString()
})

i need to get the sum of billableHours and nonBillableHours.
this is my code.
var currentMonth = 10;
var userQuery =
from timeEntry in TimeEntries
join ta in Tasks on timeEntry.TaskID equals ta.TaskID
where timeEntry.DateEntity.Month == currentMonth && timeEntry.DateEntity.Year == DateTime.Today.Year
select new
{
HoursEntered = timeEntry.HoursEntered,
Billable = ta.Billable
};
var localrows = userQuery.ToList();
var grouping = localrows.GroupBy(x => x.Billable);
var userList = grouping.Select(q => new
{
billableHours = q.Where(x=> x.Billable == true),
nonBillableHours = q.Where(x=> x.Billable != true)
});
i cannot seem to find a way to get the sum.
I need the sum of those two columns, so i can call them,
and calculate values i get from them.
When you need more than one aggregate, you can still get the result with a single query by using group by constant technique. Which in this specific case can be combined with conditional Sum:
var hoursInfo =
(from timeEntry in TimeEntries
join ta in Tasks on timeEntry.TaskID equals ta.TaskID
where timeEntry.DateEntity.Month == currentMonth && timeEntry.DateEntity.Year == DateTime.Today.Year
group new { timeEntry.HoursEntered, ta.Billable } by 1 into g
select new
{
BillableHours = g.Sum(e => e.Billable ? e.HoursEntered : 0),
NonBillableHours = g.Sum(e => !e.Billable ? e.HoursEntered : 0),
}).FirstOrDefault();
You do not need to group them. Try this query:
var userQuery =
from timeEntry in TimeEntries
join ta in Tasks on timeEntry.TaskID equals ta.TaskID
where timeEntry.DateEntity.Month == currentMonth
&& timeEntry.DateEntity.Year == DateTime.Today.Year
select new
{
HoursEntered = timeEntry.HoursEntered,
Billable = ta.Billable
};
var billableHours = userQuery
.Where(m => m.Billable) // Billable
.Select(m => m.HoursEntered)
.DefaultIfEmpty(0)
.Sum();
var nonBillableHours = userQuery
.Where(m => !m.Billable) // Non-bilable
.Select(m => m.HoursEntered)
.DefaultIfEmpty(0)
.Sum();
var currentMonth = 10;
var TimeEntries = new List<TimeEntry>() {
new TimeEntry(){TaskID = 1,DateEntity = DateTime.Now.AddDays(1),HoursEntered =2},
new TimeEntry(){TaskID = 2,DateEntity = DateTime.Now.AddDays(2),HoursEntered =3},
new TimeEntry(){TaskID = 3,DateEntity = DateTime.Now.AddDays(3),HoursEntered =2},
new TimeEntry(){TaskID = 4,DateEntity = DateTime.Now.AddDays(4),HoursEntered =4},
new TimeEntry(){TaskID = 5,DateEntity = DateTime.Now.AddDays(5),HoursEntered =2},
new TimeEntry(){TaskID = 6,DateEntity = DateTime.Now.AddDays(6),HoursEntered =6}
};
var UserTasks = new List<UserTask>(){
new UserTask(){TaskID = 1,Billable = true} ,
new UserTask(){TaskID = 2,Billable = false} ,
new UserTask(){TaskID = 3,Billable = true} ,
new UserTask(){TaskID = 4,Billable = false} ,
new UserTask(){TaskID = 5,Billable = true} ,
new UserTask(){TaskID = 6,Billable = false}
};
var userQuery =
from x in
(from timeEntry in TimeEntries
join ta in UserTasks on timeEntry.TaskID equals ta.TaskID
where timeEntry.DateEntity.Month == currentMonth && timeEntry.DateEntity.Year == DateTime.Today.Year
select new
{
HoursEntered = timeEntry.HoursEntered,
Billable = ta.Billable
})
group x by x.Billable into g
select new
{
IsBillable = g.Key,
Billabe = g.Where(t => t.Billable == true).Sum(x => x.HoursEntered),
NonBillable = g.Where(t => t.Billable == false).Sum(x => x.HoursEntered)
};
foreach (var item in userQuery.ToList())
{
Console.WriteLine(string.Format("{0} - {1}", item.IsBillable? "Billable":"Non-Billable",item.IsBillable?item.Billabe:item.NonBillable));
}
I want to know how can I write this query:
var query = from p in context.DimProduct
from psc in context.DimProductSubcategory
// on psc.ProductCategoryKey equals pc.ProductCategoryKey
where psc.EnglishProductSubcategoryName == subCategoryName
&& psc.ProductSubcategoryKey == p.ProductSubcategoryKey
select new DimProductDTO
{
ProductKey = p.ProductKey,
ProductSubcategoryKey = p.ProductSubcategoryKey,
EnglishProductName = p.EnglishProductName,
Size = p.Size,
StandardCost = p.StandardCost
};
I tried some queries, but no success. My problem is that I don't know how to have access to DimProduct and DimProductSubcategory.
Any suggestions?
context.DimProduct
.SelectMany(p => new { p, psc = context.DimProductSubcategory })
.Where(x => x.psc.EnglishProductSubcategoryName == subCategoryName
&& x.psc.ProductSubcategoryKey == x.p.ProductSubcategoryKey)
.Select(x => new DimProductDTO {
ProductKey = x.p.ProductKey,
ProductSubcategoryKey = x.p.ProductSubcategoryKey,
EnglishProductName = x.p.EnglishProductName,
Size = x.p.Size,
StandardCost = x.p.StandardCost })
However, you're not selecting anything from DimProductSubcategory, so I think the same can be done using Any() extension method:
context.DimProduct
.Where(x => context.DimProductSubcategory
.Any(y => y.EnglishProductSubcategoryName == subCategoryName
&& y.ProductSubcategoryKey == x.ProductSubcategoryKey))
.Select(x => new DimProductDTO {
ProductKey = x.ProductKey,
ProductSubcategoryKey = x.ProductSubcategoryKey,
EnglishProductName = x.EnglishProductName,
Size = x.Size,
StandardCost = x.StandardCost });
It should generate IN SQL statement within the query.
That is not exactly same query, but it produces same result via inner join (I believe that is more efficient than cross join)
context.DimProduct
.Join(context.DimProductSubcategory
.Where(x => x.EnglishProductSubcategoryName == subCategoryName),
p => ProductSubcategoryKey,
psc => ProductSubcategoryKey,
(p,psc) => new { p, psc })
.Select(x => new DimProductDTO {
ProductKey = x.p.ProductKey,
ProductSubcategoryKey = x.p.ProductSubcategoryKey,
EnglishProductName = x.p.EnglishProductName,
Size = x.p.Size,
StandardCost = x.p.StandardCost })
Also your original query can be rewritten as
var query = from p in context.DimProduct
join psc in context.DimProductSubcategory
on p.ProductSubcategoryKey equals psc.ProductSubcategoryKey
where psc.EnglishProductSubcategoryName == subCategoryName
select new DimProductDTO {
ProductKey = p.ProductKey,
ProductSubcategoryKey = p.ProductSubcategoryKey,
EnglishProductName = p.EnglishProductName,
Size = p.Size,
StandardCost = p.StandardCost
};
Generated SQL will look like:
SELECT [t0].[ProductKey], [t0].[ProductSubcategoryKey]
FROM [DimProduct] AS [t0]
INNER JOIN [DimProductSubcategory] AS [t1]
ON [t0].[EnglishProductSubcategoryName] = [t1].[ProductSubcategoryKey]
WHERE [t1].[EnglishProductSubcategoryName] = #p0

New transaction is not allowed because there are other

I'm guessing you started a transaction against that context and you never dispose of it not commit it. Just a guess though as you didn't Los any code (please post code)
Maybe you have declared cmsUnitOfWork as static variable? Context must be created and destroyed on each request
