Retrieve All The Filename Present In One Particular Location In SQL
Dec 20, 2007
Hi,
I need to read all the text files present in one particular folder and have to place all the contents in the file into a table. I will be knowing the location of the file but i will not be knowing the name of the file. I am using a BULK INSERT command to place all the contents to a table.
Eg: BULK INSERT TEST FROM '\BSSC018C$IP Office LogsLog 20071206 000000 (5).txt'
To use BULK INSERT i have to specify the location of the file with the filename. So can anyone please help me to know how the names of the file can be fetched through SQL query. If i am able to get all the file names i can use a cursor and insert all the datas from all the text files.
Thank you.

Hello. I have been challanged to build an application that keeps track of inventory and dates of every item that needs inspection on regular intervals. The original application was a .NET windows application and i have been tasked to "port" and improve it to a .NET C# web application.
The original database was in access and i have imported everyting to SQL and all the data is in a single table. So far the table is relatively small so i decided to keep the current database design.
What i need to do is to select all the items that are comming up for inspection in the comming months and present them. Each item has a uniqe article number (artnr) with the item name, category and location of the item. The location is the part i would like each items to be presented by. Basicly i would like to retrive artnr, name, type and present x number of gridviews or a sorted presentation where each item is shown inside each gw/whatever by location.
I also considered moving all locations to it's own table and connect it with a PK/FK to the prinmary article table but i dont know if this will help me or not. Basicly i have no idea how i would present the items by location where each gridview/somethign else is it's own location.
I could really use som help with how i can retrive and present the data so it is showed in the above manner.

Hi Champs,
Scenario Configuration : VB.net 2005 Code, WebService for Executing SSIS on Server, SSIS deployed on the Database Server
Problem Description : We are developing windows applicaiton in which we call webservice which was deployed on the same server where SSIS packages are deployed.
Now from Code we are passing FilePath name in variable and execute the Package. But the SSis result says that
The file name "\computernamefol1fol2fol3fol4abc.txt" specified in the connection was not valid.
More Information:
1. Full Permission are given on this network folder.
2. Package executes successfully from SSIS development solution (BIS solution)
3. Deployed packed executes successfully from the Database Server.
4. From Development pc packege executes successfully.
5. Other packages deployed on the same server executed suucessfully with same configuration and scenario.
Only this package is not executing.
-- the only differece with this package with other is -
using ".txt" extension in Flat file connection and using VB Script task
Can any one suggest the appropirate solution for this problem...
Thanks

Hi,
I've been asked to find a way to insert a row only if it's not present. I want to make sure that test and insert are atomic, so I wrote the following test cases
-- CREATE TABLE t1 ( id int, val varchar(256) )
-- GO
-- Execute the following statements in one query window
IF NOT EXISTS(SELECT * FROM t3 WHERE id = 1)
BEGIN
WAITFOR DELAY '00:00:10'
INSERT INTO t3(id, val) VALUES (1, 'Query 1')
END
GO
-- Then execute the following statements in a second query window within ten
-- seconds of the starting the first query
IF NOT EXISTS(SELECT * FROM t3 WHERE id = 1)
BEGIN
WAITFOR DELAY '00:00:10'
INSERT INTO t3(id, val) VALUES (1, 'Query 2')
END
GO
When both queries are complete there will be two rows in the table t with id = 1.
1 Query 2
1 Query 1
Wrapping the code in a transaction does not change the result. Changing the transaction isolation level to serialable causes a deadlock, but otherwise the isolation level has no effect on the result either. Adding a WITH (TABLOCK) hint to the tests do not change the result.
Our clients use a mix of SQL 2000 and SQL 2005 so TRY/CATCH blocks cannot be used.
Any suggestion on how to do this?
Thanks

I'm developing a report which contains a number of matrixes which are ordered in a hierarchy which can be navigated using a document map. One of the matrixes contains a subreport containing a table which displays a description for the matrix and the corresponding document map label. This is working without problem already in the production environment.
Recently, after updating my machine with numerous updates and patches, this stopped functioning. I now receive the error message, "The given key was not present in the dictionary" when I run this subreport, either as part of the greater report or on its own.
I have seen the posting which recommends deleting the report.rdl.data files. This did not solve the issue.
The data and the dataset are both in sync. When I click the "Print layout" button when previewing the report in Visual Studio .Net 2005, I can view the data. This looks like a bug in the VS.NET 2005 report designer.
I am running SQL Server 2005 SP2.
Any help is appreciated.
Regards,
Bill Mueller

Hi all,
Publisher
SQL 2000 Snapshot publication timed to run at 23:00 daily All tables & views are published articles.Snapshot agent runs and creates a snapshot of all articles.
Subscriber
SQL 2005 Pull subscription set to run continuously Manually run the SQL agent job and I get the following error... 2006-12-11 15:04:35.687 Agent message code 20164. Unable to replicate a view or function because the referenced objects or columns are not present on the Subscriber.
I've tried creating the subscription database from a backup so I know all the tables & views exist and also tried just creating a blank empty database - same error.
There are no user stored procedures or functions in the database.
If I'm publishing all tables & views then why should the data & structure fail to load at the subscriber? Do I need two publications, the first containing the metadata and the second containing the data?
Thanks in advance

Guys, could anyone tell me if MSSQL Server 7 has 'on delete cascade' option when creating a foreign key constraint or something similar to it. I'd really like MSSQL to remove all dependent records (child records) automatically from one table when I'm deleting a parent record from another record. I know that I can do it via trigger, but the FK constraint should be removed or disabled. I would really appreciate your help. Thank you very much.

Hi,
I have one dymic report and one of the requirement is that,I want to check whether particular field is present there or not
For e.g In one of the case Fields!Name will come and in other case it won't.
There one dynmic column which calculated values based on all the column.
If I write in value field of this column as follows.[If status = "Name" and Field is not missing then take Name value,if field name is Consumer take value from Consumer and shows it in column.]
=Switch(Fields!portfolio_status.Value="Name",IIF(Fields!IName.IsMissing,"0",Fields!Name.Value)
,Fields!portfolio_status.Value="Consumer",IIF(Fields!Consumer.IsMissing,"0",Fields!Consumer.Value))
In case,portfolio_status doesn't give me value "consumer" then I expect "0" to get printed.Problem here is that IIF expression tries to evaluate Fields!Consumer.Value even if it is not using this value and because of that my calculated column is not working.
I tried IsMissing,IsNothing..Nothing seems work.Basically I want to check if that field is there in result set or not.
IIF(IsNothing(Fields!Consumer),"0",Fields!Consumer.Value)
IIF(Fields!Consumer.Value Is Nothing,"0",Fields!Consumer.Value)

(Sorry this was posted to VWD2005 Express by mistake)
I have created a simple project using ASP.NET 2.0 which enables a user to login. I created the login user using the Web Administration Tool in Visual Studio 2005.
I created everything locally and it worked.
Locally I have 2 databases. One containing normal data (which my site uses to populate a GridView control) and the other being ASPNETDB.MDF - which contains membership (login user) data. These 2 databases sit in the App_Data folder which is in the root of the project.
I have a remote database which is hosted in a shared environment.
This is just the one database and it appears to have all tables in the one database (membership tables and normal tables - such as the one I use to populate my GridView control).
I uploaded the website and using the Database Publishing Wizard I uploaded the database data to the shared host. I also changed the connection string to point to my remote database.
If I visit the website the GridView is populating correctly (pulling data from the remote database) but when I try to login it crashes. The error is "Access denied creating App_Data sub directory".
The membership login details for the user I created are in the remote database as I have compared the data in it to the data in my ASPNETDB.MDF local database.
If I launch from within Visual Studio 2005 then it allows me to login perfectly well.
Please does anybody know why it won't let me login when I access it via the website?
Many thanks for any help,
Graham

There are two tables A and B where asset tags are present, but in one table in rows and in another in column wise.
for eg
ASSet Tag

SR-072009-00020572
SR-072009-00020571
SR-072009-00020585
HH-092009-00038342
Table B
field 1 -->Asset TAG
Record 1-->SR-072009-00020572,SR-072009-00020571,SR-062009-00020685,SR-072009-00001592,SR-072009-00001376,SR-062009-00020683,SR-092009-00001617
field 2 --> Material code
REcord 1-->121

I have a stored procedure that inserts a record, and then either returns an error or, when successful, returns the entire row. This is a method I use on sites I have developed in other languages when inserting or updating data; I am new to c#.
With C# I have a datareader executing the sp, and the insert works fine, however I get the error "Invalid attempt to read when no data is present." when I try to read the data that should be coming back. I have researched and updated my code so that I no longer get the error, but I still cannot get the data back. I trap the sp in profiler, ran it in anaylzer, and it works fine - data is returned. But in the code, it does not see the data.
I have modified the return results so now I just have the ID coming back and that works fine. But I would rather just return the entire row. Can this be done, and if so, how?
Thanks.

Dear Friends:
Could somebody please help me to stop sending scheduled report when no data is present in the report? Actually I have a daily report which is sent to the client and in a week, two or three days, data will not be there and thus it delivers blank report to the client.
So how can I stop sending blank mails to the client?
Thanks in Advance

I am using a standard dbreader type of loop in a query to retrieve data. I am running over what should be end of record set, every time.
I have altered my read procedures to use while dbreader.read() and if dbreader.read(), to attempt to avoid getting the error. Neither is stopping it.
While debugging it, as I get to the last item and actually get the error, if I check the dbreader status, it still indicates that it has rows.
Anyone have any ideas on how to get around this?
TIA, Tom

When I create a Report Server Project Using Visual Studio 2005 with SQL Server 2005 I can create a data source with no problem and the test shows it is good good.
When I next create a report and go to the query builder using that same data source and click on the query builder button I see the Query Builder screen, but there is no toggle button in the top left of the screen so I cannot go into the graphical mode to see the tables.
I have uninstalled and reinstalled both Visual Studio and SQL Server but I still have the same problem. What should I do to get the button visible on the screen?
Can anyone help?

I'm trying to determine if the record is NULL/empty or is valid from the datareader.
objReader = strCMD.ExecuteReader
objReader.Read()
if objReader.IsDBNull(0) = true then...
If NULL/Empty, display no records found. If records are found, display "1 or more records have been found". I keep getting the error "Invalid attempt to read when no data is present". I'm not sure what I am doing wrong here.
