Empty Text File
Nov 28, 2007
My team is working on a problem. Please help us solve it.
I am looping through a set of files and on each loop i process the file and move it to another folder. I am using File System task and variables with destination path and name, to do so . It works fine.
Requirement :
However now I want that after processing the file, instead of moving it, I create an empty text file at the destination containing the file name. I want to do this with minimum effort. Can anyone suggest me the way.
thanks

We have created SSIS package to load a text file into a table. Source system shares 10 text files and recently they stopped generating data for one of the text file (comping empty), after few months they will start generating the data for the empty file batch processing.
The Issue here is Data Flow task is getting failed while loading empty text file into table. How to handle this empty file load issue in SSIS package.

I'm performing an insert, and I want to insert specified text, if the field is empty. I thought it should be a simple matter of a case expression, which I have below, but it's not working:
CASE PropertyBuilding when '' then [PropertyStreetAddress] else [PropertyBuilding]end

I've production sql server 7 sp3 on windows NT. I had a 8GB data file ofwhich 5GB were used and 3GB were unused. I wanted to take back the unused3GB.So I did the following with EM GUI:1. I tried to "truncate fre space from end of the file". Didn't truncatethe file. I believe there was no empty space at the end of the file.2. Next I chose the option to "shrink file to 5GB". And to my horror thedata file instead of taking just 5GB took the empty spaces also and the sizeof the used data file went to 8GB.Any idea what's going on?TIA,SP

Here's a really annoying problem. Let's say you have a text file with 2 million rows.Delimiters all look good and rows are previewed well but the file has a missing row at say lin 1234567 - way deep in the file. When SSIS encounters the blank row, an error is raised and processing on the file STOPS! I verified this in by checking the SSIS log and have even developed an error routine to notify me via email when the error occurs (really cool if I do say so myself ). The main problem still remains - how to resume processing from the point of failure in the file? Any help is appreciated. Thanks.

I've created a test database with a test table containing just a primary key and a text column. I entered a few records in the table. Then, I built a full text index on the database, specifying my text column. I then launched a full population of the index. The server seems to work, which is confirmed by the info in the property window of the index. But when it has finished working, the index seems empty. My queries return no error, but they also return no data.
Does anyone know what I forgot to do??
Thanks in advance.

Hi,
I'm not sure this is the right place for this thread but here goes.
I am trying to setup a full text catalog on one table in my database. Although the catalog is created fine and no erros are reported when creating or populating the catalog. It seems to be empty as its size is only 1Mb and my query:
select top 10* from kmuser.tbl_webpages
where contains (WebPageHTML_FT, '"aruba"'
returns no rows, while:
select * from kmuser.tbl_webpages
where webpagehtml_ft like '%aruba%'
returns 6 rows.
I have read several articles on the subject and have followed them to a T. I've deleted it and recreated so many times now both through Enterprise manager and through query analyser using the stored procedure sp_fulltext_catalog.
I've checked that full text catalog is enabled using:
select DATABASEPROPERTY(DB_NAME(), N'IsFullTextEnabled')
I am really stuck. Does anyone have any ideas?
Many thanks

Why shrinkfile empty file does not redistribute data evenly in the primary file group with multiple files:
Please run the script attached to see what the end result is.
This is what I set up last night on my test machine.
1) Create database [FGTest] size 200MB
2) Create table called TEST on primary
3) Insert 40MB of data into test
4) Create another file group called temp in primary size 200MB
5) Shrinkfile('FGTest',emptyfile) so that all data is transfered from FGTest into temp file group.
6) Add another 2 files called DATA2 and DATA3. Both are 200MB.
7) We now have 3 empty files that I want data distributed evenly on. FGTest, DATA2 & DATA3
8) Shrinkfile('temp',emptyfile) to move all the data from temp over the 3 file groups evenly
I would expect at this stage to have the following:
FGTest = 13MB,
DATA2 = 13MB,
DATA3 = 13MB
(40MB of data over 3 files should be about 13 MBish in each file)
What I actually end up with is this:
FGTest = 20MB
DATA1 = 10MB
DATA2 = 10MB
It looks as though SQL Server is allocating 50% of all data to the original file and then 50% evenly over
the remaining files in PRIMARY.

I'm trying to do a simple update like I have done countless timesbefore.However, when I update the empty fields in this table it places a -1into the field rather than the enterred value.It is indexed with duplicates allowed.

Hi,
Here's an interesting problem. I have to set up connection managers for some files. The thing is, sometimes the files have data in them, sometimes not.
The files that don't have data in them just have some header info, so the file isn't technically empty, but I won't want to load these files when they're empty.
What would be an approach to solving this problem? I can't eliminate the file based on file size, since it's not 0, and there is no set file size that would be a reliable threshold, since they're small files to begin with.
Any ideas?
Thanks

Hi,
I'm pretty new to ASP.NET and VB, but I'm working on a project which is essentially a staff directory. Using VS 2005, I've setup a basic grid view which connects to an object which connects via a data layer to a SQL database with Name, Surname, Email, Extension No and Department fields.
I have it working so that if a user enters a name and surname for example, it will return all records with either the name matching or surname matching input parameters. What I want to do is to set up a SQL query which is:
SELECT * FROM records WHERE (Name LIKE @Name) AND (Surname LIKE @Surname) AND (Email LIKE @Email) AND (Dept LIKE @Dept)
so that if the user only enters the first name and surname for example as above, it ONLY returns the record which matches the first name and surname and not all records with either/or. One way I've thought of to do this is to convert the empty fields to "Nothing" so that it fullfils the search parameter for the empty fields. If someone can explain how to do this, or can suggest a better way, I'd be grateful.
Cheers,
Tom

i have a trigger on a table right now... when fields are inserted, theres a text field inserted and i want to check if that text field = '' (the empty string, not NULL) and if it doesn't equal that, then perform some row updates on other tables, but if it is empty, to not do anything else in the trigger... right now i have this:
Code:
IF ((SELECT Note FROM XATPoDetail WHERE ReqNbr = (SELECT ReqNbr FROM Inserted)) LIKE(''))
Note is the text field, XATPoDetail is the table where its being inserted into. I had to do the select FROM the table because it wouldn't let me select a text data type from the "Inserted" virtual table
but it tells me me "Error 279: The text, ntext, and image data types are invalid in this subquery or aggregate expression"
thanks

I am using this bcp out construct and it works fine except that if the query does not return values it bcp's out a file anyhow. This is not wanted and I am looking for a work around.
SELECT @Year = CONVERT(varchar(4), @trxYearMonthStart, 120)
SELECT @Month = RIGHT(CONVERT(varchar(7), @trxYearMonthStart, 120),2)
SELECT @cmd = 'BCP "SELECT * FROM ' + @TableToBeCleaned + ''
SELECT @cmd = @cmd + ' WHERE '+ @SelectedColumn + ' BETWEEN '
print @cmd
SELECT @cmd = @cmd + '''' + CONVERT(varchar(10),@trxYearMonthStart,120) + ''' and ''' + CONVERT(varchar(10),@trxYearMonthEnd,120) + ''''
print @cmd
SELECT @cmd = @cmd + 'AND NOT EXISTS (Select * from DBCleanerHist Where TableName = ''' + @TableToBeCleaned + ''' and sYear = '+ @Year + ' and sMonth = ' + @Month + ')'
print @cmd
SELECT @cmd = @cmd + ' " QUERYOUT ' + @DBCleanerBackUpPath+'' +@TableToBeCleaned +'_'+ @Year + '_' + @Month + '.txt '
SELECT @cmd = @cmd + ' -c -C1250 -S -Uopms -Psmpo'
EXEC master.dbo.xp_cmdshell @cmd
The subquery checks first in DBCleanerHist if a file already has been extracted onto hd and if so do not create an empty file and overwrite an existing file.
thanks

I was running a DBCC SHRINKFILE with EMPTYFILE to move data to a different drive. But somehow the autogrow got unchecked on the new file while it was running. So the shrinkfile died and the file wasn't anywhere near being empty. When I try to run it again on the file is comes back right away and says that it completed, but it hasn't moved any data. It like SQL thinks that the empty file is complete. But it isn't near being done, with about 50 GB left to go. I made sure that the new file will autogrow and that it actually can grow and also that I can write to it. I created an index on the filegroup and it went to the new file and not the old. Any help would be appreciated.
Thanks,
Anthony

Hello,I'm not getting any response to this on the SQLDTS newsgroup, so Ithought that I would try here:I just ran into this problem and I can't find any other mention of itthrough Google. I have a text file that is comma-delimited. It alsouses double quotes as text identifiers. A new column has been added tothe file, but currently has no values. I would like to finish mydevelopment so that when it does finally get some values, they will beimported as well. The problem is, the last column does not show up inDTS.I can reproduce this problem easily enough... create a text file withthe following two lines in it:1,"test",2,"test2",Now, create a new DTS package and add a text file connection. Point itto the new file and go through the properties for the file. You willnotice that on the second screen where it displays the preview of thedata there are only two columns shown.This does not happen if there is no text qualifier or if at least onerow has the final column value filled. Is there any way around thisproblem?Thanks!-Tom.

In order to troubleshoot some deadlocking that I am seeing on SQL Server, I am trying to capture the Deadlock XML by enabling the Events Extraction Settings option 'Save Deadlock XML events separately' and specifying a Deadlock XML results file.
Meanwhile, I am also tracing the Deadlock graph, Lock:Deadlock, and Lock:Deadlock Chain events. Yet the xdl file remains empty even though I am getting hits on the events themselves in the SQL Profiler trace.
Also, I have the following trace flag settings enabled.
TraceFlagStatusGlobalSession
1204110
1222110
Why the xdl file remains empty even though (I think) it should contain some XML for deadlocks that are actually happening?

Hi All,
I have a particular issue that has been causing me some problems for a while. I have an SSIS package that imports an excel file into my database, and then performs various data manipulation that I won't go into. The problem I am having is at the import end. The excel source file I am working on is provided to me by my client. It is a fixed format and doesn't change, it contains a header row and there are 32 headings. The trouble I am having is that quite often, the last column is empty, i.e. it contains no data. The header is still there, but theres no data underneath. When I try to import this file using my SSIS package it fails, and complains about needing to remove the metadata for this final column from the External Columns list (VS_NEEDSNEWMETADATA). When I try to preview this file in the properties of the Excel Data Source, the last column does not exist. It's as if it's determining that as there is no data in that final column, that it's unnecessary and not part of the data set, even though it has a header.
Now I've done a bit of research, and found cases that a sort of like mine, I know that the excel file has the first 8 records sampled to determine the data format. This problem suggested to use the IMEX=1 extension in the connection string, which didn't help. I also discovered that when using flat files, if you have odd numbers of columns in your comma seperated list there can be problems. But neither of these issues seem to match the issue I'm facing.
Has ANYONE had a similar problem to me, and can anyone offer any kind of assistance regarding what I need to do to import an excel file that may or may not have data in the final column?
Thanks in advance,
Paul

I was running an operation to shrink file/emptyfile a data file, and then remove it.
It blocked and caused a huge mess, I suspect on the removal part. But I want to confirm that the emptyfile completed (and that the engine isn't going to try to put more data in there for when I schedule the removal part again a week or more from now).
How does the engine know not to put any more data in there, and how long does that situation last?

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.

Hi,
In SSIS flat file import using fastload, I'm trying to import data into SQL 2005 previously created tables.
The table may contain column that are NULLable BUT there is NO DEFAULT for them.
If the incoming data from flat files contains nothing either between the delimeters, how can I have a NULL value inserted in the column instead of blank/empty string?
I didn't find an easy flag unless I'm doing something wrong. I know of at least two ways to do it the hard way:
1- set the DEFAULT(NULL) for EVERY column that needs this behaviour
2-set up some Derived Column option in the package to return NULL if the value is missing.
Both of the above are time consuming since I'm dealing with many tables. Is there a quick option to default the value to NULL WHEN there is NO data ELSE insert the data itself? So the same behavior that I have right now except that I want NULL in place of empty string/blank in the varchar(x) columns.
Thanks
Anatole
