SQL-CLR - Is It A Dead Subject?
Feb 15, 2008
Microsoft products that are doing well tend to have very strong communities around them, and I am starting to get a bit disappointed with SQL-CLR. This forum seems fairly light, the links int he FAQ are broken, and the official SQL-CLR blog has no update since 2006..
Taking all of that into account I am forced to wonder, Is this a dead subject?
I am not trying to say that the people in this forum are doing something wrong, nor am i claiming that no one uses SQL-CLR (i am a user, thats why im here). But I did want to get the opinion of the group here of where they think this concept stands.
I think SQL-CLR can really be a good tool in the chest for various scenarios. I am for one using it to have a generic SQL-CLR Stored Procedure that can analyze small sets of data and move it into various buckets depending on validation rules built into the code. So far its working very well, but I admit it has not yet hit production so only time will tell. (Performance is always a concern of mine)
Regards,
Dmitry.

I would like to include some information in the subject line of a report subscription email. Right now the default subject line is something like "@ReportName was executed at @ExecutionTime". is there a way to use one of my report parameters in the subject? I tried something like "Thank you for your order @OrderNum", but that did not work.
Thanks,
Stuart Fox

Hey guys, I didn't know exactly where to post this, but I'm wondering what
the legal implications of decompiling a .DLL are ?
We are using SQL Reporting Services 2005 with the Excel Export option. The
problem is that our reports have a lot of hyperlinks on each page so we can
easly navigate all the reports, but when we go ahead and export the report,
all the hyperlinks get exported too; resulting in a file atleast 10x the size.
i.e we export a report and it results in a 20mb excel file, but once we
remove all the hyper links and save it again it drops down to a 500k file.
So I was wondering, what the legality was in decompiling the Excel
Export.DLL that comes with Reporting Services and removing the Hyperlink
export functionality ?
Thanks,
Raul

Hi,
I created a report subscription windows form to talk to SSRS 2000 web services API. Everything is fine except the email subject '@ReportName was executed at @ExecutionTime' is always in American Date format.
Is there a way to customize the date format on the variable @ExecutionTime on the email subject?
Any help would be appriciated.
Thanks,

I have the variable @Monthname defined as shown below:
(MONTH(getdate()) == 1 ? "January" : MONTH(getdate()) == 2 ? "February" : MONTH(getdate()) == 3 ? "March" :Â
 MONTH(getdate()) == 4 ? "April" : MONTH(getdate()) == 5 ? "May" : MONTH(getdate()) == 6 ? "June" :Â
 MONTH(getdate()) == 7 ? "July" : MONTH(getdate()) == 8 ? "August" : MONTH(getdate()) == 9 ? "September" :Â
 MONTH(getdate()) == 10 ? "October" : MONTH(getdate()) == 11 ? "November" : MONTH(getdate()) == 12? "December":"")
By itself, it is working fine. I am attempting to have the @SubjectLine variable display the below:
CA - TFL for the month of August 2015
I am using the expression below in the expression builder:
"CA - TFL for the month of " + @[User::MonthName] + Â (DT_WSTR,4)YEAR(GETDATE())
When evaluating the expression, I get the below (month is missing):
CA - TFL for the month of 2015

Hi,
I imagine this will be done through the use of expressions.
What I would like to do is this. When my package fails, it's set up to send an email using the Send Mail Task.
I would like to create a custom subject line that contains:
1.) Name of the package
2.) Name of the task that failed (if possible)
I am seriously wondering how I can do this.
Thanks much

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 would like to create a database that keeps track of our companies subject matter experts. I have roughed out some of the tables. I would appreciate any feedback on if this is the right approach and if there might be any issues when I start writting a front-end (probably VB 2005).
What makes this interesting (at least for me) is that a subject has an owner and at least 1 "expert", possibly up to 3. Here is what I am thinking for tables:
tblEmployee
EmployeeID (PK)
LastName
FirstName
etc......
tblSubject
SubjectID (PK)
Description
tblOwner
SubjectID (FK)
EmployeeID (FK)
tblExpert1
SubjectID (FK)
EmployeeID (FK)
tblExpert2
SubjectID (FK)
EmployeeID (FK)
tblExpert3
SubjectID (FK)
EmployeeID (FK)
Does this make sense? Would I run into any issues when trying to display this on a form in VB?
Thanks in advance for any help!!!!!

I'm consistently getting >10 minute render times in a matrix based report whose underlying query only takes 1-2 seconds to run in both RS's data tab and mgt studio. The bad render times occur in preview tab, Report Viewer and when requested from Report Manager. I believe most of the time being taken is RS's attempt to pivot and present the data.
I can run a homegrown query that pivots (with unknown number of cols) the data itself in under 4 seconds but would be concerned about mapping an unknown number of columns to a table region in RS.
The matrix I'm testing with is 67 columns across (just over 2 months of daily columns) and is supposed to be 207 rows long. There is no aggregation required by RS when it is pivoting the data because each intersection occurs at most one time in the query's result set. The number of data points actually being "bucketed" is around 13,800 values. Row headers consist of 3 columns.
RS is also cutting off the number of rows it is supposed to be showing. The number of rows cutoff seems to be 100% repeatable based on the date range chosen. RS doesnt tell me when it cuts off rows that should have been displayed. From what I can tell so far, it never cuts off columns.
The number of rows cut off seems consistent across designer's preview, report viewer and when requested thru report manager. The "run" command (exclamation icon in data tab) seems to always return the correct number of unpivoted rows, just as in mgt studio.
Are there known bugs and or limitations in RS's matrix data region feature? Are there some settings or workarounds that might make it work more to my liking?

Hello !!!
I have 2 transactions, the first one has MANY updates to the table A and it finishes with a commit or rollback (ONLY AT THE END), the second one has only one insert into the table A that finishes with a commit or rollback, the problem is that the update process takes a long time to finish, and the insert process could be thrown during the first process, there's where I get everything locked cause the table A is locked and my java aplication gets stuck.
Note: When I execute each transaction independient I have no problems.
Is there any possibility to lock table A completly for the first transaction and release It for second one ??
Could you give me any suggestion of what to do step by step ?
Thanks !!!

I have a Orders table, this has a Primary key on one Column
( OrderID )
We are using a Stored Proc to insert data into this table ( I am not
starting the Transaction in the stored Proc ) as its controlled by the front end written in C++.
when ever there is a update on this Orders table I move the record to the ordershistory table. ( I have a trigger in the CTOrders table
on INSERT and UPDATE )
The C++ App does an Async I/O. Offlate the App is experiencing a few dead locks during the day espicially at the market open and Close as this database is for the Trading System.
I need a few pointers as to start debugging this.

Trying to get SQL 2005 to report dead locks via email.
I performed the following
Execute Sp_configure ‘blocked process threshold’, 200
Then generated a deadlock
BEGIN TRAN
UPDATE CUSTOMER
SET CUSTOMER_NAME = 'F'
WHERE CUSTOMER_ID = '1'
WAITFOR TIME '17:52'
ROLLBACK TRAN
Then on another query ran this
SELECT CUSTOMER_NAME FROM CUSTOMER
In sp_who i see it blocked. and the select is waiting for the update.
But i do not get anything reported in logs for the dead lock.
I tried to set up an alert.
MSSQL$ASRCFHSQL2005:Locks
Number of Deadlocks/sec
Total
rises above 1
When doing the reconfigure is something supposed to be written to the logs..........
Trying to set up system so if any dead locks arise i am sent an email

I have a SQL Server 2005 system that has been running for about 2 years. This morning nothing will connect. SQL Server Agent will not start. It gives me the message
"The request failed or the Service did not respond in a timely manner. Consult the event log or other applicable error logs."
The error log only states the SQL Server Agent cannot connect to server CANSPEC-TMMCSQLDEV and it is shutting down.
When i try to logon to SQL Server using Management Studio i get the following message:
"A connection was successfully established with the server, but then an error occured during the pre-logon handshake. Provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe. Microsoft SQL Server Error : 233"
The help for this error states that it could be caused by the fact that SQL Server does not allow remote connections. I have remote connections turned on.
Any ideas??

Hi There,
I was updating a Custome Error Log table in different Data Flow Task in a Package. Custom log table is being used to log the Redirect Rows which sent by a component if it has errors. So I am catching the error raised by componets and putting them all into one table. I thing this could be the cause for the following error. I am not sure Please help me out. What could be the cause of this error and how to prevent it?
SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005. An OLE DB record is available. Source: "Microsoft OLE DB Provider for SQL Server" Hresult: 0x80004005 Description: "Transaction (Process ID 71) was deadlocked on lock resources with another process and has been chosen as the deadlock victim.

Dear Friends,
Please help me in below unexpected error.
Server Details:
HP Proliant DL385 G1, 142*6 GB
AMD Opteron „¢ Processor 280, 2.40 GHz
4.00 GB RAM, DVD ROM
Win2K3 R2, SP1 64bit
SQL Server Details:
SQL Server 2000 Enterprise Edition 32bit
Service Pack4
Network Details:
Clients can access the server by Terminal Server and also by Direct Connectivity.
The connectivity is provided by RF network Provider.
Application Details:
Application was designed by Power Builder 6.5.
Error Details:
If I divide my clients connectivity to the server then it is divided into 3 types
TYPE A >> Users inside my LAN using a DNS server they give the server name in their Parameter file to connect to the Database Server.
TYPE B >> Users who are in WAN connect to the server by Terminal Servers for Data Input.
Terminal Servers are inside my LAN.
TYPE C >> Users who are in WAN connect to the Server by Direct Connection for Reports and Print Out they give the IP address of the Database server directly in their Parameter files.
After every 6 to 7 days the ERROR DB Processes Dead comes to the TYPE C.
The error Numbers are 100025 and 100005.
At the same time TYPE A AND TYPE B are not getting any errors.
For further diagnosis I have taken a client machine to Net Meeting and taken his desktop in control. I have connected the client machine to the database server by ISQL in command prompt.
From Backend I can see that the SQL server has allocated a SPID to the client machine. After I have executed
1>SELECT * FROM SYSDATABASES
2>GO
It will return me all data but it will not show me how many rows selected or EOF.
After some time it will give me the prompt (3>) but without EOF and after that if I give another query then it will give the below error
DB-Library: Attempt to initiate a new SQL Server Operation with results pending.
DB-Library: Unexpected EOF from SQL Server. General Network Error. Check Your Documentation.
Net-Library error 10054: ConnectionCheckForData (CheckForData())
DB-Library: DBPROCESSES is dead or not enabled.
DB-Library: DBPROCESSES is dead or not enabled.
DB-Library: DBPROCESSES is dead or not enabled.
DB-Library: DBPROCESSES is dead or not enabled.
At the same time if I give IP address of another server then it works and TYPE A and TYPE B don€™t get any problem.
To stop this error I have to restart the server after that for again seven days it works and again the same problem.
I cant find anything I have checked tempdb, cache size but it is normal no abnormal activities.
No virus Issues.
Please advice.
Regards,
James

Dear all,
I am build an application based on different WCF services which colect different type of data from an SQL database.
I can have up to 10 clients whcih could at a certain times collect the same data as a read or right operation.
I have run a test where I have only 2 clients, and I have been surprise to receive a nice error of dead lock process.
The error is as follow :
Transaction (Process ID 63) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction."
In the store procedure which I am suspected, not sure yet, I have been advise to use the
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
but no help
According to what I could notice in my application, I have one process which insert rows in this table, while clients read the same table..but I guess dead lock need to investigate in a more better way and handle it anyway...
I am not a databse administrator so I have no idea how to handle such situation.
Thnaks for your help
regards
serge
