Static Variables In A SQLCLR Stored Proc Seem To Get Reused From Execution To Execution Of The Sp
Aug 23, 2007
after moving off VS debugger and into management studio to exercise our SQLCLR sp, we notice that the 2nd execution gets an error suggesting that our static SqlCommand object is getting reused from the 1st execution (of the sp under mgt studio). If this is expected behavior, we have no problem limiting our statics to only completely reusable objects but would first like to know if this is expected? Is the fact that debugger doesnt show this behavior also expected?
are sqlclr stored proc sessions running in the same SQLOS execution model (Running, runnable and suspended status, Runnable Queue and Wait List) as other types of sessions and therefore ending up in the same queues, contending for very similar resources (except maybe for memory type because of MTL's role) etc?...or do they get treated in a very different way?
I am working with a large application and am trying to track down a bug. I believe an error that occurs in the stored procedure isbubbling back up to the application and is causing the application not to run. Don't ask why, but we do not have some of the sourcecode that was used to build the application, so I am not able to trace into the code. So basically I want to examine the stored procedure. If I run the stored procedure through Query Analyzer, I get the following error message: Msg 2758, Level 16, State 1, Procedure GetPortalSettings, Line 74RAISERROR could not locate entry for error 60002 in sysmessages. (1 row(s) affected) (1 row(s) affected) I don't know if the error message is sufficient enough to cause the application from not running? Does anyone know? If the RAISERROR occursmdiway through the stored procedure, does the stored procedure terminate execution? Also, Is there a way to trace into a stored procedure through Query Analyzer? -------------------------------------------As a side note, below is a small portion of my stored proc where the error is being raised: SELECT @PortalPermissionValue = isnull(max(PermissionValue),0)FROM Permission, PermissionType, #GroupsWHERE Permission.ResourceId = @PortalIdAND Permission.PartyId = #Groups.PartyIdAND Permission.PermissionTypeId = PermissionType.PermissionTypeId IF @PortalPermissionValue = 0BEGIN RAISERROR (60002, 16, 1) return -3END
I'm not really sure if my question should fall on Service Broker or T-SQL, but I hope someone helps me with this... After activating the stored procedure assigned to the queue, is there any way for me to find out if the stored procedure is already finished executing?
I have successfully sent messages to my queue but I have no way to know if all the processing is already done.
Interestingly enough, I haven't come across this before. I have a SQL stored procedure which takes four parameters; periodstartdate (datetime), periodenddate (end time), hsgradyearstart (int), hsgradyearend (int)
[dbo].[CalculateActivityTotal]
-- Add the parameters for the stored procedure here
@periodstartdate datetime = '2007-01-01',
@periodenddate datetime = '2007-01-08',
@hsgradyearstart int = 1900,
@hsgradyearend int = 2007 AS...
If I run the stored procedure and pass the parameters using EXEC or
the stored proc takes well over ten minutes to run (it does a bunch of aggregation). If I modify the stored procedure to take no parameters, however, and I hardcode the dates in the stored proc using declare and set then it runs in 13 seconds. What could be causing my problem and how I can I go about resolving this? I need to pass the parameters via reporting server. Thanks!
I have a stored proc that is executing in 2 sec on production and test database. It is taking more than a min on dev environment.
I have verified sqlserver version is same on both of the server.Prod is running on 2012Sp1 however dev don't have sp1. I am downloading it.
Both are 64bit, has same collation and compatibility level.I have confirmed that sp on both servers has same execution plan. I have reset and import stats from prod too.
I have 10 or so packages with package scope variables. I would like to create a package that not only runs all the packages but also sets the variables within the packages being executed.
A) Whats the best way to run all the packages from one (package??)?
B) Whats the best way to set the variables in the child packages, without having to change them manually everytime I run it.
I would like to pass variables to the package before it is executed (e.g. I am calling the bcp utility and I need to pass a password to the command line), so that at runtime a variable is set and then used.
Does anyone has some hints for good approaches? Every idea is welcome.
FYI: I do not use the bulk insert task as I need an errorlog file and the command is buggy with the errorfile option, therefore I chose the bcp approach. My connections are dynamic as far as servername and userid is concerned, but I did not find a solution for the password issue.
Hi I am slowly getting to grips with SQL Server. As a part of this, I have been attempting to work on producing more efficient queries. This post is regarding what appears to be a discrepancy between the SQL Server execution plan and the actual time taken by a query to run. My brief is to produce an attendance system for an education establishment (I presume you know I'm not an A-Level student completing a project :p ). Circa 1.5m rows per annum, testing with ~3m rows currently. College_Year could strictly be inferred from the AttDateTime however it is included as a field because it a part of just about every PK this table is ever likely to be linked to. Indexes are not fully optimised yet. Table:CREATE TABLE [dbo].[AttendanceDets] ([College_Year] [smallint] NOT NULL ,[Group_Code] [char] (12) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL ,[Student_ID] [char] (8) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL ,[Session_Date] [datetime] NOT NULL ,[Start_Time] [datetime] NOT NULL ,[Att_Code] [char] (1) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL ) ON [PRIMARY]GO CREATE CLUSTERED INDEX [IX_AltPK_Clust_AttendanceDets] ON [dbo].[AttendanceDets]([College_Year], [Group_Code], [Student_ID], [Session_Date], [Att_Code]) ON [PRIMARY]GO CREATE INDEX [All] ON [dbo].[AttendanceDets]([College_Year], [Group_Code], [Student_ID], [Session_Date], [Start_Time], [Att_Code]) ON [PRIMARY]GO CREATE INDEX [IX_AttendanceDets] ON [dbo].[AttendanceDets]([Att_Code]) ON [PRIMARY]GOALL inserts are via an overnight sproc - data comes from a third party system. Group_Code is 12 chars (no more no less), student_ID 8 chars (no more no less). I have created a simple sproc. I am using this as a benchmark against which I am testing my options. I appreciate that this sproc is an inefficient jack of all trades - it has been designed as such so I can compare its performance to more specific sprocs and possibly some dynamic SQL. Sproc:CREATE PROCEDURE [dbo].[CAMsp_Att] @College_Year AS SmallInt,@Student_ID AS VarChar(8) = '________', @Group_Code AS VarChar(12) = '____________', @Start_Date AS DateTime = '1950/01/01', @End_Date as DateTime = '2020/01/01', @Att_Code AS VarChar(1) = '_' AS IF @Start_Date = '1950/01/01'SET @Start_Date = CAST(CAST(@College_Year AS Char(4)) + '/08/31' AS DateTime) IF @End_Date = '2020/01/01'SET @End_Date = CAST(CAST(@College_Year +1 AS Char(4)) + '/07/31' AS DateTime) SELECT College_Year, Group_Code, Student_ID, Session_Date, Start_Time, Att_Code FROM dbo.AttendanceDets WHERE College_Year = @College_YearAND Group_Code LIKE @Group_CodeAND Student_ID LIKE @Student_IDAND Session_Date <= @End_DateAND Session_Date >=@Start_DateAND Att_Code LIKE @Att_CodeGOMy confusion lies with running the below script with Show Execution Plan:--SET SHOWPLAN_TEXT ON--Go DECLARE @Time as DateTime Set @Time = GetDate() select College_Year, group_code, Student_ID, Session_Date, Start_Time, Att_Code from attendanceDetswhere College_Year = 2005 AND group_code LIKE '____________' AND Student_ID LIKE '________'AND Session_Date <= '2005-11-16' AND Session_Date >= '2005-11-16' AND Att_Code LIKE '_' Print 'First query took: ' + CAST(DATEDIFF(ms, @Time, GETDATE()) AS VarCHar(5)) + ' milli-Seconds' Set @Time = GetDate() EXEC CAMsp_Att @College_Year = 2005, @Start_Date = '2005-11-16', @End_Date = '2005-11-16' Print 'Second query took: ' + CAST(DATEDIFF(ms, @Time, GETDATE()) AS VarCHar(5)) + ' milli-Seconds'GO --SET SHOWPLAN_TEXT OFF--GOThe execution plan for the first query appears miles more costly than the sproc yet it is effectively the same query with no parameters. However, my understanding is the cached plan substitutes literals for parameters anyway. In any case - the first query cost is listed as 99.52% of the batch, the sproc 0.48% (comparing the IO, cpu costs etc support this). BUT the text output is:(10639 row(s) affected) First query took: 596 milli-Seconds (10639 row(s) affected) Second query took: 2856 milli-SecondsI appreciate that logical and physical performance are not one and the same but can why is there such a huge discrepancy between the two? They are tested on a dedicated test server, and repeated running and switching the order of the queries elicits the same results. Sample data can be provided if requested but I assumed it would not shed much light. BTW - I know that additional indexes can bring the plans and execution time closer together - my question is more about the concept. If you've made it this far - many thanks.If you can enlighten me - infinite thanks.
Here's my case, I have written a stored procedure which will perform the following: 1. Grab data from a table using cursor, 2. Process data, 3. Write the result into another table
If I execute the stored procedure directly (thru VS.NET, or Query Analyser), it will run, but when I tried to execute it via a scheduled job, it fails.
I used the same record, same parameters, and the same statements to call the stored procedure.
1) Is it possible to run stored procedures at specified intervals without using the job system (through T-SQL)? I want the schedule to be independent of the MSDB database in case of temporary failures, etc.
2) Would extended stored procedures be helpful in this scenario?
i have a stored procedure that builds a dynamic insert statement & inserts data into a table. Now when I execute the sp manually with a 'exec sptest parm1,parm2', it runs fine & inserts the data in the table. But when this sp is called from within a .net application,it prepares the insert statement but does not actually insert the record in the table. It comes back with a RPC: Completed so it seems like it completed but it does not insert the record in the table. Also just after the RPC:Completed, it throws an ATTENTION with nothing in the text data. I am confused on whats going on here. The definition of ATtention in the event class implies that the query has been cancelled or it timed out. But we have no timeout on the sql server side. The application developer says there is no timeout on the application side (i dont totally believe that). so what else could cause that Attention? There is nothing in the error log as well. Also why does the trace come back with a RPC:Completed when the stored procedure did NOT insert any data? Does the RPC:Complete only mean that the RPC completed - irrespective of success or failure? If the sp failed or had an error will it still come back with a rpc:completed? Any thoughts are appreciated...
i want to know the execution status of a stored procedure . That is i want to know whether the stored procedure was executed succesfully or not.If not i want to get the error message
I am looking for a way to count the number of times a stored procedure on the database has been executed over let's say over a period of time(month, years, etc).
Is there a system stored procedure or a system table that stores that information.
I am struggling to find some information about this topic Thanks for the help
Hi. When SqlServer executes a procedure (any type: select, update, insert) after it´s executed can I get a default status for this executed procedure, like a return bool value from SqlServer as true for successfull and false for failed to execute?
Hi,There is a stored procedure which runs through job.It is calling to other stored procedure and other stored procedures arecalling to another .. so on (approx 12-15 sp in batch)Problem:Sometime it does not execute properly. (approx very rare... once in 500execution or sometime on new site/database)I want to know the reason for it.If anybody have faced the similar problem.Please tell the possible causes and possible solutions.Thanks in Adv.T.S.Negi(MIND)

I have a big problem with slow execution of stored procedure in SQL Server 2005 but I really don't understand the reason. I have a database with large table (about 400 million rows) and simple stored procedure to get data from that table (one select statement to select time and value columns).
Strange thing is that if I call that stored procedure from .net application (native SqlDataProvider) it takes about 6 seconds to execute but if I call the same procedure with the same parameters from within SQL Server Management Studio it takes only 25 milliseconds to execute!
I've noticed that from .net, procedure is called with binary data and in Management Studio sql script is executed so I've copied/pasted the script from Management Studio to .net code and again the same thing happens (6 seconds from .net and 25ms from Management Studio). I traced executions with SQL Profiler and everything seems to be identical for both applications except it takes much longer time for .net application.
Both SQL Server Management Studio and .net application are on the same machine and SQL Server is on another.
This is the query that when executed in Management Studio takes 25ms:
At first I thought that Management Studio somehow caches results but if I change parameters of stored procedure it always takes less than 30ms to execute. I really don't understand this. Please, help!
I want to simulate 100 users simultaneously executing a procedure in sql server (best example would be 100 users using one report with different parameters in ssrs at the same time ). can i do that ?
Hi all,I have a problem with a stored procedure.This stored procedure inserts around bout 500,000 records but when it is executed it takes about 15-16 hours to do so.The stored procedure is using a temporary table to do this and is also calling a function.Please let me know if there is a way to reduce the execution time.will a cursor help? Thanks, Anne.

I have a .Net application which invokes an stored procedure (SQL Server 2005 Express installed on the same machine). When the stored procedure is called the first time, the application hangs because the sp never ends execution and the application's process has to be killed. But when the application is executed again, the sp runs as expected. What could be happening?
The stored procedure references remote tables by means of synonyms. If the Management Studio is used instead, the sp never ends execution when invoked the first time, but the query can be cancelled.
Now, if the sp is invoked first in the Management Studio first and then by the application, this does not hang (the sp executes as expected).
Hello friends! I have one query regarding execution of SSIS package through Stored Procedure.
I have created SSIS package which extract data from database and put that into various text files.Here I am using two global variables one is for Department ID and another is path where I wanna to place my text files as per departments.When I ran it through command prompt it works fine but now I want that dtsx package to run from stored procedure with same input parameters

i have a few stored procedures called by an application that i would like to create execution plans for every time they are run. is there a way to do this? or are execution plans only done through the Sql Server Query Editor? these queries make comparisons between a temp table and a master table and setting up the data for the tables is time consuming. so id like to automate it by setting the store procedure to create the execution plan at runtime.
