Timeout Expired When Run A Stored Procedure From Aspx Page.
Mar 2, 2004I have a stored procedure when query a big table about 500,000 records. When I run the stored procedure in the query analyzer, it is very fast and it only takes 2~3 seconds. However, when my aspx page try to call this stored-procedure with a Command's ExecuteReader method like bellow:
SqlDataReader myReader = myCommand.ExecuteReader();
I always get timeout expired exception. I try to set the connection timeout and command timeout to 100 seconds. The exception is gone but the average execution time is about 25 seconds! While the stored-procedure only takes about 2~3 seconds in query analyzer with the same parameter.
What could be the problem?? I tried to figure this out for a couple days but still no clue.
Thanks.
Stored Procedure To Update/refresh Aspx Page
May 5, 2004Hello,
I have a table which gets updated roughly every 6 seconds with data. I have setup an aspx page with a datagrid to meta tag refresh every 3 seconds.
Because the data sometimes stops for a couple of minutes or even hours, I was thinking of a way to update/refresh the aspx page only when the table data gets entered ( to stop page flickering every 3 seconds).
I was thinking about a stored procedure and using an on update procedure.
Does anyone have any preffered methods or suggestions on the best way to accomplish this task.
I use VB.Net
Thanks

Business Logic File Needs Something...
Feb 26, 2008Or maybe it can't find something it's looking for to make my additional symetrical with everything else. This is from one of my businesslogic files. What causes Visual Studio to not allow me to add something here and have it behave like the other parameters/ I'm talking about ShortDesc. Visual studio inserted () and the Get instead of GET like all the others. It would not allow me to capitalize the "get". There has to be a reason for this. Currently my program is adding all of the fields except the ShortDesc to the table in my database. Does anyone have any thoughts as to why this is the case?

Business Logic Handler Not Loading
Nov 7, 2006I'm trying to implement a custom conflict resolver by inheriting from
Microsoft.SqlServer.Replication.BusinessLogicSupport.BusinessLogicModule. The replication is between a SQL Server 2005 Express subscriber and a SQL Server 2005 publisher/distributer.
The problem is that the resolver class in the DLL will not load; although, it does appear to find the DLL. (If I rename the DLL I get a "file not found error"). The exact error message is:
Microsoft.SqlServer.Replication.ComErrorException
"Error loading custom class "MergeConflictHandler" from custom assembly "MergeConflictHandler",
Error : "Could not load type 'MergeConflictHandler' from assembly 'MergeConflictHandler, Version=1.0.2502.22393, Culture=neutral, PublicKeyToken=0403e50cc4dc27fa'."."}
I placed the DLL in the directory of the program that calls SynchronizationAgent.Synchronize and tried it with and without being registered in the GAC. There was no change. Interestingly, when I move the file out of that location, but register it in the GAC, the file is not found. Thinking it may be a security problem, I gave Everyone Read & Execute and Read privileges. I believe the class is actually instantiated by replmerge.exe, an apparantly unmanaged app, so I tried marking it ComVisible. No Luck.
I registered the resolver with the following T-SQL code:
sp_registercustomresolver @article_resolver = 'eClinical Notes Conflict Resolver'
, @is_dotnet_assembly = 'true'
, @dotnet_assembly_name = 'MergeConflictHandler'
, @dotnet_class_name = 'MergeConflictHandler'
, @resolver_clsid = Null
The resolver I've created is not much more than a shell at this point. It is pasted below, but I tried using the code found on MSDN character-for-character and had the same problem.
using System;
using System.Text;
using System.Data;
using System.Data.Common;
using Microsoft.SqlServer.Replication.BusinessLogicSupport;
namespace MergeConflictHandler
{
public class MergeConflictHandler :
Microsoft.SqlServer.Replication.BusinessLogicSupport.BusinessLogicModule

public override void Initialize(string publisher, string subscriber, string distributor, string publisherDB, string subscriberDB,string articleName)

m_PublisherName = publisher;
m_SubscriberName = subscriber;
m_Artical_Name = articleName;
}
// Declare what types of row changes, conflicts, or errors to handle.
public override ChangeStates HandledChangeStates
{
get
{
return ChangeStates.UpdateConflicts;
}
}
public override ActionOnUpdateConflict UpdateConflictsHandler(DataSet publisherDataSet, DataSet subscriberDataSet, ref DataSet customDataSet, ref ConflictLogType conflictLogType, ref string customConflictMessage, ref int historyLogLevel, ref string historyLogMessage)
{
if (m_Artical_Name == "PatientAllergies")
{
// Accept the updated data in the Subscriber's data set and apply it to the Publisher.
}
return ActionOnUpdateConflict.AcceptPublisherData;
}
}
}
Does anyone have any thoughts or advice? (Help!)

Business Logic Handler Question

I am performing the Merge Replication of Timesheet table between SQL server 2005 and SQL CE on the Pocket PC. For one of the article, I would like to perform web synch for only those rows which have certain field set to true.
I am trying to use Business Logic Handler to implement this logic. I am using following code out of sample on MSDN web site. However I am not sure if this code gets executed for each row for a table during synch or does this get executed once for each table? The answer would help me write logic on applying synch changes only for few rows.
Thanks

// Set the reference parameter to write the line to the log file.
historyLogMessage = updatedDataSet.Tables["tbl_timesheets"].Rows[0]["ts_id"].ToString();
// Set the history log level to the default verbose level.
historyLogLevel = 1;
// Accept the updated data in the Subscriber's data set and apply it to the Publisher.
return ActionOnDataChange.AcceptData;
}
else
{
return ActionOnDataChange.RejectData;

View 2 Replies View RelatedSqlDataSource? What Happened To The Separation Of UI And Business Logic?
Mar 16, 2007I guess I just don't get the reasoning behind the new SqlDataSource control. Haven't we just spent the last decade or so evangelizing and learning how and why to separate business logic from the display in VB 6 and VS.NET? In this age of programming for disparate devices (desktop, mobile, PocketPC, etc.) when this separation makes more sense than ever, why is MS pushing us to go back to putting our logic and data access rules and objects back in the display? It doesn't make sense. Why would anyone do this? And why would all the experts and MVPs at ASP.NET, DevX, 4GuysFromRolla, etc., go along with this?

Transact SQL :: Adding Constraint For Business Logic
May 27, 2015ALTER TABLE [dbo].[bkrm_lendcoll] ADD CONSTRAINT
   ReqdCovgAmt_constraint33 CHECK   Â
( caseÂ
 when CovgAmt = 0 and  ReqdCovgAmt = 0 then 1
 when CovgAmt = 0 and  ReqdCovgAmt = 1 then 1
 when CovgAmt = 1 and  ReqdCovgAmt = 0 then 1
 when CovgAmt = 1 and  ReqdCovgAmt = 1 then 0
end =1
)
This is my first attempt to add a constraint for business logic. Â The desired behavior is that the two columns together have the same behavior as a radio button. Â (one can be true, the other true, both can be false, but both cannot be true.) I get this error when I attempt to update it.
The ALTER TABLE statement conflicted with the CHECK constraint "ReqdCovgAmt_constraint33". The conflict occurred in database "Std", table "dbo.lendcoll".
So, basically my question is, when you have two bit columns and want them to have the truth table such as described, how can I set a Check constraint to enforce this?
Running Custom Business Logic During Synchronization
Oct 30, 2006I have a merge replication topology that allows some subscribers (clients) to retreive a number for certain columns (ie invoice number, order number, etc).
I have implemented a custom business logic handler to check for inserts from the subscriber and before updating the server, I call a stored proc on the server to generate a new number. I update the data set and call ActionOnDataChange.AcceptCustomData. This works great for the publication db but I am trying to get this new number back into the subscription db. I am using web synchronization so I really don't have a connection back to the subscriber database.
Any Ideas? I was thinking about keeping track of the updates myself and build a sql string and somehow get that back to the subscriber to run updates for those columns... I am wondering if I am pushing the limits of the business logic handler? Was it designed to do this? Of course the easy answer is to modify my client application but I am trying to avoid that at this point.
Any help/suggestions would be greatly appreciated!
Multiple Tables In Business Logic Handler
Oct 25, 2007Hi,
I have 2 related tables in SQL 2005. I am using Business Logic Handler on one of those tables during Merge Replication to reject data for few rows during web synchronization. Once a row is rejected, I would like to run the Business Logic Handler for the related table to reject changes for the row with same foreign key as the rejected row in first table.
Not sure if I need to create separate Business Logic Handlers for each table or can it be achieved in a single Handler.
Also is it possible to get a list of rejected rows back from the handler?
Thanks for help.
Custom Business Logic Handler Question
Mar 1, 2007I am currenly have a simple merge replication topology. The publisher-distibutor is SQL Server 2005 and the subscriber is a SQL Server Express. The type of subscription is non anonymous pull.
I made a custom business logic handler class that is trying the following:
When a new record is inserted in a published table on the pubsliher, some additional records are added in a differenct table in subscriber. Then the "InsertHandler" method returns "AcceptData" in order to allow the agent to add the new record in current table also.
So I am establishing a new connection to the subscriber and I am trying to add the additional recs in the different table. The problem is that this different table is also published as read-only on the subscriber. So my insert fails saying that table is not updatable.
Is there any way to bypass this problem?
In fact I realised in general that when my custom logic handler performs some DML operations on the subscriber, these are NOT considered as part of the replication e.g. the NOT FOR REPLICATION constraints and triggers are active for these operations.
Is this normal?
Merge Replication – Bug In Business Logic Update Handler
Nov 17, 2006I have got a business logic update conflict handler working, but I have had to work round what appears to be a bug.
Please can someone confirm if this is indeed a bug €“ and if it is a known bug?
My conflict handler needs to take some columns from the publisher row and some from the subscriber row in the event of conflict.
I can quite happily generate a custom dataset which contains the winning row that I want €“ I can see that because I can step through the conflict handler with debug when a conflict occurs.
However, just returning ActionOnUpdateConflict.AcceptCustomConflictData from the UpdateConflictsHandler method does not set the publisher and subscriber columns correctly. I end up with different values on the two databases.
I have found that the only way to get the correct rows on both publisher and subscriber is to create a new ADO connection to the publisher and actually perform an update €“ updating all the modified columns. This now works reliably in my testing.
Fortunately, due to business rules the frequency of update conflicts are likely to be very infrequent, but I would very much like to avoid having to do the €˜unnecessary€™ update.
Notes:
I am using column level tracking €“ but I have seen the problem with row level tracking too
I have mainly been using SP1 but have repeated the test on a configuration using the SP2 CTP €“ and the problem occurs there too
The problem is not due to complex logic in my code. If the method just sets customDataSet = publisherDataSet.Copy and then returns ActionOnUpdateConflict.AcceptCustomConflictData, the changed and winning publisher values are not sent to the subscriber
Any thoughts would be much appreciated

View 1 Replies View RelatedIssues About Deploy Business Logic Handler To A Web Server For Web Replication.
Jul 23, 2007Pocket PC 2003, SQL Compact Edition, SQL2005, IIS6.0
I implemented a business logic handler to deal with conflicts. When I deploy it on the SQL server which is also the web replication server, the logic handler seems working fine. However, if I deploy this handler to another web server. The logic handler failed to be loaded.
My enviroment settings are desribed as below.
Machine A, distributor, with database and publication. The business logic handler is deployed at C:Program FilesMicrosoft SQL Server90COMBusinessLogicHandler.dll. It's registered by using sp_registercustomresolver. The @assembly is specified as @assembly=C:Program FilesMicrosoft SQL Server90COMBusinessLogicHandler.dll';
Machine B, IIS server. The same business logic handler is deployed at C:Program FilesMicrosoft SQL Server90COMBusinessLogicHandler.dll on the Machine B itself.
When I ran the web replication, the Merge Agent reported the error as below.
Error loading custom assembly "C:Program FilesMicrosoft SQL Server90COMBusinessLogicHandler.dll", Error: "Could not load file or assembly 'C:\Program Files\Microsoft SQL Server\90\COM\BusinessLogicHandler.dll' or one of its dependencies. The given assembly name or codebase was invalid.
It seemed that the Merge Agent had trouble to find my logic handler because the path reported in the error log has two backward slashes. I have no idea where did that came from. I am not sure if that's the cause of the error. Without business logic handler. I had successfully finished web replication of Machine B to sync with Machine A. If I setup web replication directly on Machine A with business logic handler, I can successfully sync as well.
Does anyone has any idea about how to correctly deploy business logic handler on a web server?
Thanks,

List All SQL/VS.NET Objects On An Aspx Page?

Being new to ASP.NET, I may be asking something that is dead simple, but please bear with me!
How would I go about listing all the tables, stored procedures and views from a SQL database within an aspx page? I understand how to connect and return a dataset etc, but that's about as far as I can get. I want to be able to list all of these objects from a given db - any ideas?
Additionally (this may not be possible) - is there a way I can list all of the objects within a visual studio.net solution, again within an aspx page?
Thanks for any help,
