SQL Server To Generate XML Instead Of Redendant Query..file Open During Write Problem Or Job Not Running...
Jul 23, 2005
Here's a challenge that is killing me:
I've got 2 web servers and a SQL Server and about 5,000 'users' who
stay connected to the site all day. I have a page that is supposed to
be 'real-time', so to do this, I have a 1px frame that refreshes every
15 seconds (so the other frame doesn't have to reload all the time--the
top only reloads when a new record or a changed record hits the db).
The real time data can be filtered in about 8 different ways.
Currently, I have each user querying a table that contains 1 record,
including the max ID and the most current insert/update posting date.
The browser contains a cookie with that date. When the browser receives
notification that there is some new info on the server, it refreshes
the top page and reloads the data. This is happening for all users. So,
I thought to eliminate the 5,000 users running the same (or close
variations) of the same query each time a records is inserted/updated,
that I would generate an XML file with the current day's data.
In a dev environment this works 'ok'. I'm doing this by running an
ActiveX job on the SQL Server that calls a stored proc (FOR XML) and
writes the content to a file. Then from the web servers, I'm querying
this file for the new timestamp and then if newer than the cookie,
grabbing the XML (using the httprequest in the ASP XMLDOM) and using
XSLT to transform the data instead of parameterizing the queries.
Theoretically I love this solution. Problems happen in a LIVE
environment where either the file is being written to or the job isn't
able to run. When 2 records are trying to be written within the same
second, the file isn't being written (or maybe that the http requesting
the XML is keeping the file locked?)....anyway...this is a HUGE proble
that I can't seem to solve. Once we roll to .NET I think storing the
dataset in cache and updating cache (still don't know how I'll trigger
that without each user checking the db)....
Long winded, sorry...help?

I want to write a query to generate a report. I have a date column which will be holding all the business dates. No dates of Saturday and Sunday are allowed. What I am looking for is, I want to get the result of every 5th business day of each month. A month could start with any day. I just want only the 5th business day.

I recently installed standalone version of SQL 2014 Standard on my work computer. I used Access before but I want to use a SQL server instead.
We have a shared drive that a file gets deposited every day at midnight. I want to be able to get this file and import it to the server (its basically a list of names).
Here what I have done so far:
I created the database
Created the file and successfully imported data into it using the Import Data feature.
I saved the SSIS package
Scheduled an Agent Job for this package to run at certain time,daily
At first the jobs would fail with a Access is Denied. I added a user under Credentials with my network account ( have admin rights on the work computer).Also added a Proxy for the Credential user I made.
Jobs fail with a “Cannot open data file” error. I tried changing things here and there, but I can’t get it to work.

Hi,
I created a SSIS package which will generate an output file and place it on a remote fileshare location which will look something like this
\RemoteServerNameRemoteFilePath
The package is executing fine when I am executing it through BIDS or through execute package utility and writing the output file to remote file share location.
I created a SQL job for the package and ran the Job. Then, its throwing an error saying
Executed as user: DomainUser. Microsoft (R) SQL Server Execute Package Utility Version 9.00.3042.00 for 32-bit Copyright (C) Microsoft Corp 1984-2005. All rights reserved.

End Error DTExec: The package execution returned DTSER_FAILURE (1). Started: 10:33:06 AM Finished: 10:33:22 AM Elapsed: 15.891 seconds. The package execution failed. The step failed.
DomainUser have all the permissions on the remote file share location.
SQL server agent is running with the log-on account DomainUser(same as the above).
Could anyone help me in resolving this issue.
Thanks & Regards,
Sriram.

Hi,
I tried to backup the master key by the following syntax :
OPEN MASTER KEY DECRYPTION BY PASSWORD = 'mypassword'
BACKUP MASTER KEY TO FILE = 'c: empmaster' ENCRYPTION BY PASSWORD = 'mypassword'
but it failed and i got the following message:
Cannot write into file 'c: empmaster'. Verify that you have write permissions, that the file path is valid, and that the file does not already exist.
NB: I am using the "sa" user to execute this command.
I know that we have a security permission issue , but where and how ?

I need to write a process to get file size in kb and record count in a file. I was planning on writing a c# console app that takes the file path and name as a param however should i use a CLR?
I cant put a script in the ssis when it's bringing the file down because it has been deemed that we only use ssis for file consumption.

Hi
I need to generate a text file from SQL Server. The task automatically runs daily.
The format of the text file use "/" to separate the field and the row. At the end of the file, it adds number of char and uses "". The number of char includes the data parts and excludes a few word of "the number of char".
For example,
The underline fonts mean the first row record. The Bold fonts mean the second row record. The Italic fonts mean the third row record. The red fonts mean the number of char and the end of file.
1/060222/008888/234/1/7441/2/BB/10000//////290025/////1/060222/008888/234/1/7441/3/XX/100-//////290025/////1/060222/008881/234/1/7442/2/BB/10000//////290025/////161

I have a report that returns a field with the location of a .csv file on the network. The value of the field looks like this:
\ServerNamedatafile.csv
I need to let the user click a link to open the file. Simply making the Jump To Url under navigation the field value doesn't work; it's not clickable. I've tried a javascript new window command, but I'm no good at javascript.
All my google results turn up unrelated items because I'm searching "ssrs open file" or "ssrs open file in windows explorer".
Any ideas?
Thanks.

Hi,
I need to export data from a table of SQL server 2000 database, into an Excel 2000 sheet. I tried following query from the sql query analyzer
Code SnippetSELECT * INTO [Excel 4.0;Database=F:ew.xls].[sheet1] FROM tab1
It gave me following error
Code SnippetServer: Msg 2760, Level 16, State 1, Line 1
Specified owner name 'Excel 4.0;Database=F:ew.xls' either does not exist or you do not have permission to use it.
The F:ew.xls file is present and it has no additional security applied, hence I think it should be writable.
Please tell me where am I doing wrong.
I don't know if this is the correct news group or not. Let me know if I have to post to some other news group.

Hi Guys, how many connections does sql 2005 express allow to .mdf file. I stumpled on info on a microsoft site (actually a forum post on msdn) that sql server express allows only a single connection to an .mdf file.
Iam intrested in this because i developed reporting services reports in BIS and iam having problems. If i run a report from report manager, i have to wait for close to 20 minutes before i can be able to run my asp.net application agian. Else if i insert data or retrieve data from my asp.net application, then i have to wait again for 20 minutes or more before i can be able to run my reports else i will get an error that a connection can not be made to the database or that the database is being used by another process.
So in all cases, i have to wait for 20--30 minutes before a connection can be made to the .mdf file. i.e after running a report or after inserting or retrieving data from the database through my asp.net application.
Iam using sql sever 2005 express with advanced services and visual web developer on windows server 2003.
Any ideas or help.

I have a SQL Server 2005 database file (a .mdf file) that I am trying to open in SQL Server Management Studio so I can add a field to a table, but I am unable to open the file. I can't say that I really understand how SQL Server handles these databases. I especially don't understand the "attaching" and "detaching" operations.
I am working in VB.Net 2008 now, but my background is with VB6 using the JET engine. It was just so straightforward using the JET engine, but seems so much more complicated with SQL Server. I am trying to use .mdf files the same way I used .mdb files. I want my application to find the database file, "attach to it", and let me manipulate it.
At one time I was able to open my database in Sql Server Management Studio and edit the design of the database. The application still works but I am no longer able to modify the database because I cannot attach to it in Management Studio.
Here is a big clue: the files are no longer in the special folder anymore, which is c:Program Files (x86)Microsoft SQL ServerMSSQL.2MSSQLDATA. I might have deleted the files, stupidly, thinking they were redundant. I still have the .mdf file (and the _log.ldf file) on my hard drive and the application can still open it, but when I try to use Management Studio to attach to the .mdf file, I get this error:
Microsoft SQL Server Management Studio Express
An error occurred when attaching the database(s). Click the hyperlink in the Message column for details.
here are the details:
Unable to open the physical file "c:Program Files (x86)Microsoft SQL ServerMSSQL.2MSSQLDATAHEALSExamsSQL.mdf". Operating system error 2: "2(The system cannot find the file specified.)". (.Net SqlClient Data Provider)
Indeed the file is not there, but why is Mgmt Studio looking there? Why doesn't it just open the file where it is? What can I do to get it back? I even copied the files to c:Program Files (x86)Microsoft SQL ServerMSSQL.2MSSQLDATA? I get the same error.
Here is another clue: In Management Studio, when I right-click Databases, and chose Attach, it brings up a dialog. There I click "Add" to get another dialog in which I will select a database, but before the dialog appears I get this error:
Locate Database Files - KURANT-WIN7SQLEXPRESS
C:UsersJason KurantDesktop
Cannot access the specified path or file on the server. Verify that you have the necessary security privileges and that the path or file exists.
If you know that the service account can access a specific file, type in the full path for the file in the File Name control in the Locate dialog box.

Just wondering if there is any query which can give me report of locked account in SQL 2008. I know there are options like:-
1) Can go in ssms--security--account and right click and select status. This is applicable to individual account.
2)SELECT LOGINPROPERTY('accountid', 'IsLocked'). Also applicable to individual account
3) SELECT name,type_desc,is_disabled,modify_date,default_database_name from sys.server_principals order by type_desc
Generate the report but give the informatio as is_disabled. But I think is_disabled <> is_locked.
