I been trying to get sqlcachedependecy working, but it doesn't appear to work
I got the proper settings in my web.config and also global.asa, however when I run this query and the changes are made to the database from either with in or outside the web site the cached objects are not updated please someone help? I know its not because this query is querying a view, because I tested this using straight SqlDependecy and the notification works fine.
public IQueryable<VictoryList> GetVictoryList()
{
string cacheKey = HttpContext.Current.User.Identity.Name + "victoryCacheKey";
IQueryable<VictoryList> cachednews = (IQueryable<VictoryList>)HttpContext.Current.Cache.Get(cacheKey);
if (cachednews == null)
{
var results = from v in _datacontext.ViewVictoryLists
orderby _datacontext.GetNewId()
select new VictoryList
{
MemberID = v.MemberID,
Username = v.Aspnetusername,
Location = v.Location,
DaimokuGoal = v.DaimokuGoal,
PreviewImageID = v.PreviewImageID,
TotalDaimoku = v.TotalDaimoku,
TotalDeterminations = v.TotalDeterminations,
DeterminationID = v.DeterminationID,
DeterminationName = v.DeterminationName
};
results = results.ToList().AsQueryable();
SqlCacheDependencyAdmin.EnableNotifications(_datacontext.Connection.ConnectionString);
SqlCacheDependency dependency =
new SqlCacheDependency(_datacontext.GetCommand(results) as SqlCommand);
HttpContext.Current.Cache.Insert(cacheKey, results, dependency);
return results;
}
return cachednews;
}
According to the stated Limitations for creating a query for notification, listed at msdn...
The statement must not reference a view.

I am using Akka.Net (v 1.3.2) and am trying to query the event journal for all events with a specific tag. I only want the events that exist at the time I query the journal. Inside an actor, I have the following code:
var readJournal = PersistenceQuery.Get(Context.System).ReadJournalFor<SqlReadJournal>(SqlReadJournal.Identifier);
var stream = readJournal.CurrentEventsByTag("The Tag Name", Offset.NoOffset());
var materializer = ActorMaterializer.Create(Context.System);
stream.RunForeach(envelope =>
{
// Do some stuff with the EventEnvelope
}, materializer).Wait();
This will successfully query the event journal. However, the problem is it will only return the first 100 events. I need all of them that match the query!
Question: How do I remove the limit/filter that exists when querying the event journal by tag name?
If you need it, here is my akka.persistence configuration:
var config = Akka.Configuration.ConfigurationFactory.ParseString(#"
akka.persistence {
journal {
plugin = ""akka.persistence.journal.sql-server""
sql-server {
class = ""Akka.Persistence.SqlServer.Journal.SqlServerJournal, Akka.Persistence.SqlServer""
connection-string = """ + connectionString + #"""
schema-name = dbo
table-name = __akka_EventJournal
metadata-table-name = __akka_Metadata
auto-initialize = on
}
}
snapshot-store {
plugin = ""akka.persistence.snapshot-store.sql-server""
sql-server {
class = ""Akka.Persistence.SqlServer.Snapshot.SqlServerSnapshotStore, Akka.Persistence.SqlServer""
connection-string = """ + connectionString + #"""
schema-name = dbo
table-name = __akka_SnapshotStore
auto-initialize = on
}
}
}"
);
There are two things to check out:
You can set the maximum number of messages returned in one query by setting up akka.persistence.query.journal.sql.max-buffer-size value (see: reference.conf).
Use readJournal.EventsByTag instead of readJournal.CurrentEventsByTag to get a continuous stream of events. Just keep in mind, that it won't complete by itself, but will live on waiting for new events to arrive. You can stop it explicitly i.e. by using KillSwitch.
I have an interesting little problem. My controller is assigning values to the properties in my model using two tables. In one of the tables, I have some entries that I made a while ago, and also some that I've just added recently. The old entries are being assigned values correctly, but the new entries assign NULL even though they're in the same table and were created in the same fashion.
Controller
[HttpPost]
[Authorize]
public ActionResult VerifyReservationInfo(RoomDataView model)
{
string loginName = User.Identity.Name;
UserManager UM = new UserManager();
UserProfileView UPV = UM.GetUserProfile(UM.GetUserID(loginName));
RoomAndReservationModel RoomResModel = new RoomAndReservationModel();
List<RoomProfileView> RoomsSelectedList = new List<RoomProfileView>();
GetSelectedRooms(model, RoomsSelectedList);
RoomResModel.RoomResRmProfile = RoomsSelectedList;
RoomResModel.GuestId = UPV.SYSUserID;
RoomResModel.FirstName = UPV.FirstName;
RoomResModel.LastName = UPV.LastName;
RoomResModel.PhoneNumber = UPV.PhoneNumber;
return View(RoomResModel);
}

public UserProfileView GetUserProfile(int userID)
{
UserProfileView UPV = new UserProfileView();
ResortDBEntities db = new ResortDBEntities();
{
var user = db.SYSUsers.Find(userID);
if (user != null)
{
UPV.SYSUserID = user.SYSUserID;
UPV.LoginName = user.LoginName;
UPV.Password = user.PasswordEncryptedText;
var SUP = db.SYSUserProfiles.Find(userID);
if (SUP != null)
{
UPV.FirstName = SUP.FirstName;
UPV.LastName = SUP.LastName;
UPV.PhoneNumber = SUP.PhoneNumber;
UPV.Gender = SUP.Gender;
}
var SUR = db.SYSUserRoles.Find(userID);
if (SUR != null)
{
UPV.LOOKUPRoleID = SUR.LOOKUPRoleID;
UPV.RoleName = SUR.LOOKUPRole.RoleName;
UPV.IsRoleActive = SUR.IsActive;
}
}
}
return UPV;
}
The issue I see is that this database has a somewhat poor design, and that particular record fell into the trap of that poor design. Consider that you have two ID's on that table:
SYSUserProfileID
SYSUserID
That's usually an indication of a bad design (though I'm not sure you can change it), if you can, you should merge anything that uses SYSUserID to use SYSUserProfileID.
This is bad because that last row has two different ID's. When you use db.Find(someId) Entity Framework will look for the Primary Key (SYSUserProfileID in this case) which is 19 for that row. But by the sounds of it, you also need to find it by the SYSUserID which is 28 for that row.
Personally, I'd ditch SYSUserID if at all possible. Otherwise, you need to correct the code so that it looks for the right ID column at the right times (this will be a massive PITA in the future), or correct that record so that the SYSUserID and SYSUserProfileID match. Either of these should fix this problem, but changing that record may break other things.
I am new to SalesForce (3 months).
Thus far I have been able to create an application in C# that I can use to preform Inserts and Updates to the SalesForce database. These transactions are one at a time.
No I have the need to preform large scale transactions. For example updating thousands of records at a time. Doing them one by one would quickly put us over our allotted API calls per 24 hour period.
I want to utilize the available bulk transactions process to cut down on the number of API calls. Thus far I have not had much luck coding this nor have I found any such documentation.
If anyone could either provide some generic examples or steer me to reliable documentation on the subject I would greatly appreciate it.
FYI, the data I need to use to do the updates and inserts comes from an IBM Unidata database sitting on an AIX machine. So direct web services communication is not realy possible. Getting the data from Unidata has been my headache. I have that worked out. Now the bulk api to SalesForce is my new headache.
Thanks in advance.

You don't mention which API you're currently using, but using the soap partner or enterprise APIs you can write records to salesforce 200 at a time. (the create/update/upsert calls all take an array of SObjects).
Using the bulk API you can send data in chunks of thousands of rows at a time.
You can find the documentation for both sets of APIs here
The answers already given are a good start; however, are you sure you need to actually write a custom app that uses the bulk API? The salesforce data loader is a pretty robust tool, includes a command line interface, and can use either the "normal" or bulk data API's. Unless you are needing to do fancy logic as part of your insert/updates, or some sort of more real-time / on-demand loading, the data loader is going to be a better option than a custom app.
(this is the SOAP code though, not the Salesforce "Bulk API" ; careful not to confuse the two)
Mighy be below code provide clear insight on how to do bulk insertion.
/// Demonstrates how to create one or more Account records via the API
public void CreateAccountSample()
{
Account account1 = new Account();
Account account2 = new Account();
// Set some fields on the account1 object. Name field is not set
// so this record should fail as it is a required field.
account1.BillingCity = "Wichita";
account1.BillingCountry = "US";
account1.BillingState = "KA";
account1.BillingStreet = "4322 Haystack Boulevard";
account1.BillingPostalCode = "87901";
// Set some fields on the account2 object
account2.Name = "Golden Straw";
account2.BillingCity = "Oakland";
account2.BillingCountry = "US";
account2.BillingState = "CA";
account2.BillingStreet = "666 Raiders Boulevard";
account2.BillingPostalCode = "97502";
// Create an array of SObjects to hold the accounts
sObject[] accounts = new sObject[2];
// Add the accounts to the SObject array
accounts[0] = account1;
accounts[1] = account2;
// Invoke the create() call
try
{
SaveResult[] saveResults = binding.create(accounts);
// Handle the results
for (int i = 0; i < saveResults.Length; i++)
{
// Determine whether create() succeeded or had errors
if (saveResults[i].success)
{
// No errors, so retrieve the Id created for this record
Console.WriteLine("An Account was created with Id: {0}",
saveResults[i].id);
}
else
{
Console.WriteLine("Item {0} had an error updating", i);
// Handle the errors
foreach (Error error in saveResults[i].errors)
{
Console.WriteLine("Error code is: {0}",
error.statusCode.ToString());
Console.WriteLine("Error message: {0}", error.message);
}
}
}

Please find the small code which may help you to insert the data into salesforce objects using c# and WSDL APIs. I stuck to much to write code in c#. I assigned using direct index after spiting you can use your ways.
I split the column using | (pipe sign). You may change this and also <br>, \n, etc. (row and column breaking)
Means you can enter N rows which are in your HTML/text file. I wrote the program to add order by my designers who put the order on other website and fetch the data from e-commerce website and who has no interface for the salesforce to add/view the order records. I created one object for the same. and add following columns in the object.
Your suggestions are welcome.

I have a requirement to display lists of newly-created and updated pages in our Episerver intranet - say the last ten of each. I've tried using FindPagesWithCriteria but this returns no results. Here's the code I've tried:
PageDataCollection recentPages;
PropertyCriteriaCollection criteria;
PropertyCriteria upperBound;
PropertyCriteria lowerBound;
criteria = new PropertyCriteriaCollection();
upperBound = new PropertyCriteria();
upperBound.Condition = CompareCondition.LessThan;
upperBound.Type = PropertyDataType.Date;
upperBound.Value = DateTime.Today.ToString();
upperBound.Name = "Created"; // Or Saved for updated pages
criteria.Add(upperBound);
lowerBound = new PropertyCriteria();
lowerBound.Condition = CompareCondition.GreaterThan;
lowerBound.Type = PropertyDataType.Date;
lowerBound.Value = DateTime.Today.AddDays(-7).ToString();
lowerBound.Name = "Created";
criteria.Add(lowerBound);
recentPages = DataFactory.Instance.FindPagesWithCriteria(PageReference.StartPage, criteria);
I've also tried using the RecentlyChangedPagesFinder (as detailed here) - this returns some results, but when I try to use the set of results to build a PageCollection to databind into a PageList, again I get nothing output. And I can't see that I could use that for new pages, only updated ones.
The property name should be "PageCreated".
http://epiwiki.se/developing/properties/all-built-in-properties
You can also improve your FindPagesWithCriteria-syntax by going something like this:
var criterias = new PropertyCriteriaCollection
{
new PropertyCriteria()
{
Name = "SomeProp",
Type = PropertyDataType.PageType,
Value = "eh",
Condition = CompareCondition.Equal,
Required = true
},
new PropertyCriteria()
{
...
};
var pages = DataFactory.Instance.FindPagesWithCriteria(somePageLink, criterias);
I am currently building a web site and I just implemented SqlCacheDependency using LinqToSQL like so.
public IQueryable<VictoryList> GetVictoryList()
{
string cacheKey = HttpContext.Current.User.Identity.Name + "victoryCacheKey";
IQueryable<VictoryList> cachednews = (IQueryable<VictoryList>)HttpContext.Current.Cache.Get(cacheKey);
if (cachednews == null)
{
var results = from v in _datacontext.ViewVictoryLists
orderby _datacontext.GetNewId()
select new VictoryList
{
MemberID = v.MemberID,
Username = v.Aspnetusername,
Location = v.Location,
DaimokuGoal = v.DaimokuGoal,
PreviewImageID = v.PreviewImageID,
TotalDaimoku = v.TotalDaimoku,
TotalDeterminations = v.TotalDeterminations,
DeterminationID = v.DeterminationID,
DeterminationName = v.DeterminationName
};
SqlCacheDependency dependency =
new SqlCacheDependency(_datacontext.GetCommand(results) as SqlCommand);
HttpContext.Current.Cache.Add(cacheKey, results, dependency, DateTime.MaxValue,
TimeSpan.Zero, CacheItemPriority.Normal, null);
return results.ToList().AsQueryable();
}
return cachednews;
}
It appears to be working as things are noticbly faster especially on some complex queries, however while looking at things in SQLProfiler I still see the query run through, I'm using the CommandBroker mode of SqlCacheDependency. Should I still see the query even though the data is obviously coming from a cached object?
I think that the problem is that you are storing IQueryable's in your cache, and then cachednews contains an IQueryable that hits the database.
Try the following changes.
public IQueryable<VictoryList> GetVictoryList() {
// ...
if (cachednews == null)
{
var results = from // ...
results = results.ToList().AsQueryable(); // force query execution
SqlCacheDependency dependency = // ...;
HttpContext.Current.Cache.Add(cacheKey,
results, // now just the result are stored
dependency,
DateTime.MaxValue,
TimeSpan.Zero,
CacheItemPriority.Normal,
null);
return results;
}
return cachednews;
}
