How To Check For A File Existence In A Folder In SSIS
Oct 26, 2007
I have a data flow task inside a foreach loop container which will take multiple excel files and load into a sql table. Once all the excel files are loaded into the table, then at the end one of the column gets updated using execute sql task. Now I am trying to check for a file existence, if the file is not present in the folder then the data flow task should not be executed. Any help is greatly appreciated, I am thinking of using file system task for this, but not exactly sure. Thanks in advance.

I know a WMI event watcher can be used to watch for a new file being added to a folder. However, I need to check for new folders being added to an existing folder. I haven't been able to find a post on doing this. Is there a way in WQL to check for a new folder being added instead of a new file? I've used SQL for years, but am new to SSIS.

Two questions actually ...
1) Need a simple routine or system function for testing for or verifying the existence of a file or folder on the local server's file system. Returning a simple boolean value or 1 or 0 would be fine.
2) Need a syntax and use description of the new "master.dbo.xp_create_subdir" function ... anyone have some documentation or links? MS technet and MSDN have nothing.
Thanx

I am not sure if we can execute SSIS package using t-sql, but I want to do the following:
Step1. Execute SSIS package1
Step2. Check for the file1.txt in c drive using the below code:
Declare @result int
exec xp_fileexist 'c:file1.txt', @result output
IF (@result = 1) --if file exists exec ssis package
begin
Execute SSIS package2
end
If we can't use t-sql, please let me know how I can do that as part of sql job. Thanks!!

Usual way to check if file exists
DECLARE @File_Exists INT
EXEC Master.dbo.xp_fileexist 'serverBSQL_Backupfile.bak', @File_Exists OUT
print @File_Exists
1
And if check folder, can use "nul", but it doesn't work for UNC path
DECLARE @File_Exists INT
EXEC Master.dbo.xp_fileexist 'serverBSQL_Backup
ul', @File_Exists OUT
print @File_Exists
0
If use xp_subdirs like:
EXEC master.dbo.xp_subdirs 'serverBSQL_Backups'
If the folder doesn't exists,
Msg 22006, Level 16, State 1, Line 3
xp_subdirs could not access 'ServerBSQL_Backups*.*': FindFirstFile() returned error 67, 'The network name cannot be found.'
How to check if UNC folder exists in Backup? in my code I want to check if the unc folder exists before doing backup, the unc path is retrieved from other table or backup history.

I have a webpage where users can connect with other users by sending them a request. Sending the request just puts a row in a connect table that contains the users id, the targetusers id, a requesteddate, an accepted date and a disconnectdate (for the original requester to end the connection and a reject bit the the target can reject the request. Hoever I need to check to assure that the connect does nt already exist either as pending (requestdate is not null and accept date is null) or both dates are not null (connection already complete.).
ALTER PROCEDURE [dbo].[requestConnect]
-- Add the parameters for the stored procedure here
@requestor int,
@requested int

Dear All,
I wanted to know how do I know or check that whether a column exists in a table. What function or method should I use to find out that a column has already exists in a table.
When I run a T-SQL script which i have written does not work. Here is how I have written:
IF Object_ID('ColumnA') IS NOT NULL
ALTER TABLE [dbo].[Table1] DROP COLUMN [ColumnA]
GO
I badly need some help.

Apologies if this has been answered before, but the "Search" function doesn't seem to be working on these forums the last couple of days.
I'd just like to check if a table already exists before dropping it so that I can avoid an error if it doesn't exist. Doing a web search, I've tried along the lines of
"If (object_id(sensor_stream) is not null) drop table sensor_stream"
and
"If exists (select * from sensor_stream) drop table sensor_stream"
In both of these cases I get the error: "There was an error parsing the query. [ Token line number = 1,Token line offset = 1,Token in error = if ]"
Sooooo... what is the standard way to check for existence of a table before dropping it? Someone help? This seems like it should be simple, but I can't figure it out.
Thanks in advance!

we tried out the following code in query analyser -
create procedure TrialProc
as
select * from sakjdhf
when we executed this piece of TSQL in query analyser, we expected it to give an error or warning that no object by the name of sakjdhf exists ( as actually there is no such table or view in the database ). however to our surprise we got "command completed successfully " !!
does this mean the SQL server does not check for necessary objects when creating a stored procedure ? or is there some setting that we missed out whihch is causing SQL server to overlook the error in the code ?

This function, F_TEMP_TABLE_EXISTS, checks for the existence of a temp table (## name or # name), and returns a 1 if it exists, and returns a 0 if it doesn't exist.
The script creates the function and tests it. The expected test results are also included.
This was tested with SQL 2000 only.
if objectproperty(object_id('dbo.F_TEMP_TABLE_EXISTS'),'IsScalarFunction') = 1
begin drop function dbo.F_TEMP_TABLE_EXISTS end
go
create function dbo.F_TEMP_TABLE_EXISTS
( @temp_table_name sysname )
returns int
as
/*
Function: F_TEMP_TABLE_EXISTS
Checks for the existence of a temp table
(## name or # name), and returns a 1 if
it exists, and returns a 0 if it doesn't exist.
*/
begin
if exists (
select *
from
tempdb.dbo.sysobjects o
where
o.xtype in ('U')and
o.id = object_id( N'tempdb..'+@temp_table_name )
)
begin return 1 end
return 0
end
go
print 'Create temp tables for testing'
create table #temp (x int)
go
create table ##temp2 (x int)
go
print 'Test if temp tables exist'
select
[Table Exists] = dbo.F_TEMP_TABLE_EXISTS ( NM ),
[Table Name] = NM
from
(
select nm = '#temp' union all
select nm = '##temp2' union all
select nm = '##temp' union all
select nm = '#temp2'
) a
print 'Check if table #temp exists'
if dbo.F_TEMP_TABLE_EXISTS ( '#temp' ) = 1
print '#temp exists'
else
print '#temp does not exist'
print 'Check if table ##temp4 exists'
if dbo.F_TEMP_TABLE_EXISTS ( '##temp4' ) = 1
print '##temp4 exists'
else
print '##temp4 does not exist'
go
-- Drop temp tables used for testing,
-- after using function F_TEMP_TABLE_EXISTS
-- to check if they exist.
if dbo.F_TEMP_TABLE_EXISTS ( '#temp' ) = 1
begin
print 'drop table #temp'
drop table #temp
end
if dbo.F_TEMP_TABLE_EXISTS ( '##temp2' ) = 1
begin
print 'drop table ##temp2'
drop table ##temp2
end
Test Results:

I'm trying to figure out the best way to write a script to deploy environment variables to different servers. To create the variable I'm currently using catalog. create_environment_variable. I want to wrap that in an if not exist statement.I had thought about just blowing away all the variables and recreating them but I thought that wouldn't go over well in prod. I wasn't sure if by deleting the variable, references to the variable would be lost.

Hi,
newbie to sql2005. I am trying to write a VB.NET program to list all ssis packages we have stored in a file folder (not in MSDB) where both SqlServer and ssis servers are located. These packages currently running on daily basis by automated jobs with no problem.
I have found the following link on the web that includes VB.Net program. If you scroll down under Example (SSIS Package Store) , you'll see a VB.NET program that I am trying to get it to work for me but keep getting error message like "Cannot find folder......"
http://msdn2.microsoft.com/en-us/library/ms403343.aspx
My goal is to:
1. List all ssis packages stored in the file systems (.dstx)
2. List DB source and distination providers(tables in/out) in a ssis package
3. List properties for DB providers
4. List FlatFile & Excel file provider properties in a ssis package.
My assumption, but not sure, is that I may need to register this file folder (where packages are located) to the SqlServer if that is not done already. Any command or sys table in Sql2005 to figure this out?
I would appreciate any help on this in advance.
Thank You.

I have a requirement to create a package that takes all files in a given folder and adds them to a single archive (.zip) file. I've tried several methods using 7zip and while I can create archives for every file in the directory I can't seem to get them into a single .zip file.

Ok,
I have a network folder called A
I have a SharePoint (2007) Document Library site called B. Web Client is enabled on the server and B is mapped as a Drive (let's call it Y for this discussion)
I want to move documents in A to B. Easy enough, right? Not so....
I first started by creating a batch file that issues a COPY \A \Y /Y at the command prompt. Viola! Worked Great!
I then moved that command to a SQL Agent job as a CMDExec statement (exact same statement) and attempted to run it.....CRASH! It found the files in A but then said "The system cannot find the path specified"
Ok, so I tried it in SSIS. CRASH! Checked the error log. Same thing...
So I then checked the account under which the SQl Agent was running (special domain account for all our SQL Servers). Thinking it might mater I changed it to run under my name (I'm in Domain admin). I also ensured I had permissions to the SPS 2007 library as well. (I did).
Ran again! CRASH! Same error....
So, I created a batch file , placed thec ommand in the batch file and ran that from the command prompt! Viola! Worked Great.
So, I was thinking of how ingenious I was as I pasted my C:RootCopy.bat into my SQL Agent job. With a big grin on my face I right clicked and picked "Start Job at step".......CRASH! Same error.
Does anyone have any ideas on this ???????????????
Thanks,
Stephen

Hi all,
Let me apologize in advance for what I know is a very basic question,
but so far I'm not being terribly successful trying to find sample code
to learn from.
I'm trying to write (my first!) .Net Script in SSIS to check for the
existance of a file (since that seems to be the only way to do it).
I've created the Script Task, with the following settings:
PrecomplieScriptIntoBinaryCode = False (it complained at one point in time (possibly on validation))
EntryPoint = ScriptMain
ReadOnly Variables = ProductBuyListFileLocation, ProductBuyListFileName
ReadWrite Variable = FileFound
Now the ReadOnly variables have the 2 components necessary for a file location, i.e.:
ProductBuyListFileLocation = 'D:TestingProductInformationEnhancements'
ProductBuyListFileName = 'buyList.xls'
So, I'm now trying to check the existance with the following .Net Script code:
-------code--------
Imports System
Imports System.Data
Imports System.Math
Imports System.IO
Imports Microsoft.SqlServer.Dts.Runtime
Public Class ScriptMain
' The execution engine calls this method when the task executes.
' To access the object model, use the Dts object. Connections, variables, events,
' and logging features are available as static members of the Dts class.
' Before returning from this method, set the value of Dts.TaskResult to indicate success or failure.
'
' To open Code and Text Editor Help, press F1.
' To open Object Browser, press Ctrl+Alt+J.
Public Sub Main()
'
' Add your code here
'
Dim FileLocation As String
Dim DTSVariables As Variables
If
System.IO.File.Exists((CStr(DTSVariables("ProductBuyListFileLocation").Value)
+ (CStr(DTSVariables("ProductBuyListFileLocation").Value)))) Then
DTSVariables("FileFound").Value = 1
Else
DTSVariables("FileFound").Value = 0
End If
Dts.TaskResult = Dts.Results.Success
End Sub
End Class
-------code--------
if fails with this message, which I'm not finding too helpful:
at
ScriptTask_6c9d28f1bd3045739c4237bd588e3835.ScriptMain.Main() in
dts://Scripts/ScriptTask_6c9d28f1bd3045739c4237bd588e3835/ScriptMain:line

Is it complaining about not being able to find/address my ReadOnly variable? If so, what am I doing wrong?
TIA

I am having problem with moving a file from one folder to another folder. Here is the detailed scenario:
I want to move a input.csv file from shared input folder to shared archive folder. i am using the below code to do this.
declare @inpath varchar(100)
SET @inpath = 'move "\abcdefINPUTinput*.csv" "\abcdefARCHIVEarchive.csv"'
EXEC @filestatus = master..xp_cmdshell @inpath
but the problem was it was cutting the input.csv file from INPUT folder but not pasting it in the ARCHIVE folder.
I really appreciate if anyone can help me to solve this or anyone can tell some workarounds.

Hi,
Does TSQL provide methods to check if a file exists?
For example, a TSQL script will read data in a .dbf file into SQL Server. It will check if the file exists before read. How to do this check?

OK. Here's my situation. I check for the existence of a dummy .txt file using a script. I send an e-mail if it does not exist and exit package. The .txt file only exists if another .xls file is present which I import. However, during the validation phase of the package, the package fails because the .xls file does not exist. Is there a way to bypass the validation step? The only solution I came up with is to have a two-step job. The first runs the file check step and sends the e-mail. The second attemps to run the package and fails. Not a very graceful exit.

Hello everyone - wonder if you can help.
How do you process all files in an FTP directory - similar to the for each loop for files.
I need to be able to download each file and then move it to an archive folder on the ftp site.
Might also want to do some things in between.
I have a feeling it means getting the directory listing into a recordset or variable then enumerating that.
Sounds like a common requirement and would be quite easy by other means. Can't help feeling that SSIS has built in tasks to do it.

Since i have 5 different projects all has the same kind of reports., but calling via 5 different sites all sites on same webserver.
The problem i have is the .rds file name is same in all 5 report projects and it is a shared datasource., now when i compile the report project it will not load or overwrite the .rds file since the name is same, for that reason i tried to have the .rds file in reports folder as a datasource not a shared datasource. but i tried to add it, after i create the datasource, it is automatically going into the shared datasource folder, how can i create a datasource not shared under reports folder.
Thank you very much for all your help and information.
