How Can I Always Close A Text File From A CLR Stored Procedure Even When The Process Is Killed?
Mar 6, 2007
I have a C# SQL 2005 .net stored procedure which scrubs a text file looking for characters not in a range of characters and replacing them with another character. This works fine except when the process is killed. When this happens the file handle of the file being scrubbed is not released. I use a try catch finally block when opening the file and the output file. The finally section fiushes the output file and closes all files and streams but still when I go to access the file again or use the file in explorer it says the file is still in use. Should I be handling this some other way? How do I know the files will always be closed correctly.

When I was trying to get my maintenance plans to work there were many processes I had to kill. These processes were killed over a week ago but they still list in the Current Activity | Process Info list. Under Command it says "Killed/Rollback". If I go into QA and run kill 65 with statusonly it says the process is complete. How do I get these processes off the list?

I have a test database for the end users to test their select queries for reports.
One of my users is writing queries that cause locking in the database. I killed the process last evening and they are in Killed/Rollback status but are still hogging 90% of the CPU resources for the past 12 hrs. I tried killing them several times but no go.
I know that the best way to clear of these processes is by restarting SQL Server. If that is not an option is there is any other way we can clean these processes?
Also the user running these queries has a read only and create view access to the database. From my experience processes that go into Kill/Rollback state after you kill them are processes associated with some update transaction. Since the user as far as i know is running Select commands would an infinite loop cause this ?
thanks

I have a query to refer to the data source in as400 with ODBC 'iSeries Access for Windows ODBC data source' and a linked server with 'oledb for ODBC driver' in SQL2005 (9.0.2047)
Now we got 2 problems,
1. When we refer to the view with openquery e.g select * from openquery (abc, 'select * from dates')
This query continue to run without ending. In Activity monitor, we found that it is waiting for resource ole db
2. Since the process continue to run without ending, I kill the process in activity monitor or by command 'kill'. It shows the status 'KILLED/ROLLBACK' and it returns 'SPID 197: transaction rollback in progress. Estimated rollback completion: 0%. Estimated time remaining: 0 seconds.' in 'kill 197 with STATUSONLY'
In problem 1, I found some ppl encountered the same problem (waiting for resource oledb) with openquery to different data source e.g. vfp, oracle.
In problem 2, we can't restart the sql server for clear the unkillable process
Kindly advise. Thanks in advance.

Hi!!!
Is it possible to create a stored procedure which will create a text file (containing information from some tables) and send it via e-mail to a list of user.
I know that I will have to configure the SQL Mail.
If it is possible, can someone give me sample code.
Thanks you.

Want to write from a table variable to a text file from a stored procedure.Read about xp_cmdshell bcp etc. but worried because it's supposed to be a security problem and needs to be from a permanent database.Also am getting error "The EXECUTE permission was denied on the object 'xp_cmdshell'..."
1. Is xp_cmdshell a bad idea to use even if I get permissions ?
2. Can a "permanent" table be used in a stored procedure starting out fresh each time with 0 rows rather than use a table variable ?

Hi,
I want to create a text file and write to text it by calling its assembly from Stored Procedure. Full Detail is given below
I write a code in class to create a text file and write text in it.
1) I creat a class in Visual Basic.Net 2005, whose code is given below:
Imports System
Imports System.IO
Imports Microsoft.VisualBasic
Imports System.Diagnostics
Public Class WLog
Public Shared Sub LogToTextFile(ByVal LogName As String, ByVal newMessage As String)
Dim w As StreamWriter = File.AppendText(LogName)
LogIt(newMessage, w)
w.Close()
End Sub
Public Shared Sub LogIt(ByVal logMessage As String, ByVal wr As StreamWriter)
wr.Write(ControlChars.CrLf & "Log Entry:")
wr.WriteLine("(0) {1}", DateTime.Now.ToLongTimeString(), DateTime.Now.ToLongDateString())
wr.WriteLine(" :")
wr.WriteLine(" :{0}", logMessage)
wr.WriteLine("---------------------------")
wr.Flush()
End Sub
Public Shared Sub LotToEventLog(ByVal errorMessage As String)
Dim log As System.Diagnostics.EventLog = New System.Diagnostics.EventLog
log.Source = "My Application"
log.WriteEntry(errorMessage)
End Sub
End Class
2) Make & register its assembly, in SQL Server 2005.
3)Create Stored Procedure as given below:
CREATE PROCEDURE dbo.SP_LogTextFile
(
@LogName nvarchar(255), @NewMessage nvarchar(255)
)
AS EXTERNAL NAME
[asmLog].[WriteLog.WLog].[LogToTextFile]
4) When i execute this stored procedure as
Execute SP_LogTextFile 'C:Test.txt','Message1'
5) Then i got the following error
Msg 6522, Level 16, State 1, Procedure SP_LogTextFile, Line 0
A .NET Framework error occurred during execution of user defined routine or aggregate 'SP_LogTextFile':
System.UnauthorizedAccessException: Access to the path 'C:Test.txt' is denied.

Currently through my stored procedure, I am pulling the data from my source systems in the way Daily Truncate and loading the data in to my database table. Currently my query looks as follows,
SELECT
a.col1,a.col2,b.col3,b.col4,c.col5
FROM
a
left outer join b ON a.col1 = b.col1
left outer join c ON b.col1 = c.col1.
Now, I want to change the above one to delta process(I have updateddate field in all the tables). The requirement is any of these 3 tables has updateddate = getdate() then i need to take "a.col1,a.col2,b.col3,b.col4,c.col5" columns and push to destination
table.
I think usually delta process means we will use to consider the key table, in that table if there is an updated record will take that record and join with the other required tables to pull the updated record. But these logic seems different.how to build the query for the above delta process? Since it is an urgent requirement need to implement asap.

I am trying to follow an exercise for debugging a stored procedure in the .net IDE. I have had success in adding a connection to the application, until I get the point of where I should set a BreakPoint in the stored procedure "Ten Most Expensive Products" which belongs to the Northwind database. When I open Sever Explorer -->Data Connections- ->WI0001.NorthWind.dbo-->Stored Procedures and Right-click the procedure, the context menu does not give me an edit item to select to open this SP in the editor. Nor can I double-click on the stored procedure to open it either.

Hello all,
I am running into an interesting scenario on my desktop. I'm running developer edition on Windows XP Professional (9.00.3042.00 SP2 Developer Edition). OS is autopatched via corporate policy and I saw some patches go in last week. This machine is also a hand-me-down so I don't have a clean install of the databases on the machine but I am local admin.
So, starting last week after a forced remote reboot (also a policy) I noticed a few of the databases didn't start back up. I chalked it up to the hard shutdown and went along my merry way. Friday however I know I shut my machine down nicely and this morning when I booted up, I was in the same state I was last Wenesday. 7 of the 18 databases on my machine came up with
FCB:pen: Operating system error 32(The process cannot access the file because it is being used by another process.) occurred while creating or opening file 'C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataTest.mdf'. Diagnose and correct the operating system error, and retry the operation.
and it also logs
FCB:pen failed: Could not open file C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataTest.mdf for file number 1. OS error: 32(The process cannot access the file because it is being used by another process.).
I've caught references to the auto close feature being a possible culprit, no dice as the databases in question are set to False. Recovery mode varies on the databases from Simple to Full. If I cycle the SQL Server service, whatever transient issue it was having with those files is gone.
As much as I'd love to disable the virus scanner, network security would not be amused. The data and log files appear to have the same permissions as unaffected database files. Nothing's set to read only or archive as I've caught on other forums as possible gremlins. I have sufficient disk space and the databases are set for unrestricted growth.
Any thoughts on what I could look at? If it was everything coming up in RECOVERY_PENDING it's make more sense to me than a hit or miss type of thing I'm experiencing now.

Hi,
I have an ActiveX script running in a DTS package that checks for the existence on an Access.mdb file (using the filesystemobject), deletes the file if it's there and then re-creates a fresh empty Access database (using ADOX). This is great except one problem. If someone has the original Access mdb file open while I'm running this script, it's impossible to delete the file while its 'in use'. I'm not sure how to get around this problem. I've tried researching the filesystemobject to see if I can close the existing file before deleting it but the only Close method I found applies to text stream documents created with fso.
Does anyone have any ideas about how solve this problem?

Hi,I've got some XML which exists as a text variable in a temp table in SQL Server 2000.I need to pass this XML into sp_xml_preparedocument so I can rebuild a table out of it. But I can't figure out the syntax.If I try doing this:declare @idoc intexec sp_xml_preparedocument @idoc output, (select XmlResult from #cache)I get an error, with or without the brackets round the select statement.The temp table is created using an SP, but I can't call that directly either. This:declare @idoc intexec sp_xml_preparedocument @idoc output, exec Search$GetCache @searchIDAlso throws an error.I can't put it into a
local variable because they can't be of type text. I can't pass it into
the SP somewhere as it's being generated on the fly.How can I get my xml into sp_xml_preparedocument?Cheers,Matt

Hi,
I have a problem with importing text into a database.
I have an application in .net where I fill a textbox with a certain text. When I press a button the text shall be separated and inserted into a database. The big question here is: how do I seperate the text so I get it into different colums in the database?
I know there is someting called InString, should I use this or is there an other way? I was thinking I could use a stored procedure.
Thanks in advance.

I am trying to inject dynamically generated text into a Sql2000 stored procedure. What am I doing wrong?A code behind routine generates the following string value based on a visitor entering 'sail boats' in TextBox1. The routine splits the entry and creates the below string.Companies.L_Keywords LIKE '%sail%' AND Companies.L_Keywords LIKE '%boats%'
I am trying to place this string result in the WHERE statement of a Sql2000 Stored Procedure using parameter @VisitorKeywords.
PROCEDURE dbo.KWsearchAS SELECT DISTINCT Companies.L_Name, Companies.L_ID, Companies.L_EnabledWHERE ( @visitorKeywords ) AND (Companies.L_Enabled = 1)ORDER BY Companies.L_Name
I am wanting the resulting WHERE portion to be:
WHERE ( Companies.L_Keywords LIKE '%sail%' AND Companies.L_Keywords LIKE '%boats%' ) AND (Companies.L_Enabled = 1)
Thank you

I want to sort a stored procedure based on a variable passed to it... what is the easiest way to do this? Here's an example of what I want to do:
sp_select_thing 10, 'thing_name', 'asc'
It would run the query then somehow evaluate parameters 2 and 3 to be placed in the ORDER BY clause. I'm not sure if they should be quoted as strings or not, I don't have an idea how to pass a "reference to a variable" as a parameter to a stored procedure... or even if such a thing is possible
Thanks!
