Beginer Problem: Is There Any Way To Create The Destination File At Runtime?
Feb 13, 2007
I have to generate flat files from SQL Server tables. Its a backup package for few tables which will be run daily. I want the names of the destination flat files to be automatically generated at run time.
I created an expression for the Flat file destination connection and appended the date and the time to the flat file name. For today my file name is 'table02-12-2007.txt'. for tomorrow it should be 'table02-13-2007'. When I evaluate the expression it shows the correct value.
But when i run the package, I receive an error indicating - Destination file is not found. Error is because the destination file is not present at runtime and I was hoping that the package will be create the file on the fly.
Is there any way to create the destination file at runtime? Or Am I missing a step?
Any help will be greatly appreciated.
Thanks

Hi,
I am having a Data flow task in For each loop which will gets 100 sourcetable names and 100 target table names...
am having a simpleData flow task which trasferes from OLEDBSource to OLEDBDestination.
I am repeating the Dataflow task which transfers from sourcetablename extracted from for loop to a destination table var.
The problem am gettting is for the first table it is able to transfer correcly because I did mapping for those tables at design time...but for the next coming sourcetable-desttable (which r having different no of cols,datatypes) its giving Validation failed...and...needs to refresh metadata....
is there any way to refresh the metadata of Data flow task (I set the property of OLEDBSource validate external meta to false then also same error is coming)
Thanks

Hello friends,
I have the following (simplified):
1. Flat File Source
2. Conditional Split, Case Good = !ISNULL(KEY) Case Error = ISNULL(KEY)
3. Case Good -> Writes to Good Flat File (with timestamp in the title)
4. Case Error -> Writes to Error Flat File (with timestamp in the title)
Most job runs have no errors but the error file is created as a zero byte file anyway. If there are no error records I don't want the error file created. How might I accomplish this?
Thanks

I am trying to create a text file from an SQL query on a SQL table. I would like the SSIS package to prompt for the file name and path. The text file is tab delimited and the text qualifier is a double quote.
Thanks,

I have a select Script as follows:
SELECT c.ABC AS 'ABC'
, a.Qty AS 'Quantity_Recived'
, b.PC AS 'PC'
, b.PC AS 'PC'
, 'I' AS 'Flag'
FROM TNRInventory.dbo.tInventoryAlloc AS a
LEFT OUTER JOIN vwInventoryAllocMapping AS vwMap ON a.TNRAllocTypeID = vwMap.TNRInventoryAllocID
LEFT OUTER JOIN ABC.dbo.ZREFRESHTAB AS b ON a.DispenserID = b.Asset
LEFT OUTER JOIN ABC.dbo.TableJoinKey AS c ON a.TitleID = c.TITLE_ID
WHERE (vwMap.DataSourceID = 3) and vwMap.[DataSourceAllocName] = 'I'
group by c.SKU_NO , vwMap.[DataSourceAllocName],a.Qty , b.Profit_Center
order by c.SKU_NO,vwMap.[DataSourceAllocName]
GO
i have to send the result of aforesaid script in batch of 300 records per file (tab delimited text file)
now the file name must be dynamically created as each file will contain 300 records.
I have found some document related to same issue on this url
http://forums.microsoft.com/TechNet/ShowPost.aspx?PostID=1238184&SiteID=17
but still there is a catch.
Can any one guide/suggest me better way to do the aforesaid.
Thanks

Hi,
I have a data task with the following requirements:
1) Run query against database to retrieve rows
2) Add header and footer row to the result set. The footer row must contain a count of the records.
3) Write the rows to a fixed width file if there were any data rows
I have got to the point that I can create the file (using a set of tasks that includes derived columns, sorts, aggregation and merges). However the file is created regardless of whether there were data rows returned.
I can't check the row count before proceeding as this isn't set until the data task ends. And if I try to split them into separate data tasks (so that I can access this variable and perform conditional execution) it becomes harder to access the original rows.
Do you have any recommendations on the best way to achieve this?
It all seems to be very complex and I'm starting to feel that it would be easier to do this outside of SSIS...
Please help me to keep the faith!
For those interested this is a slightly simplified version of what I have so far (all within a single data task):
1.Run dummy sql to create header row 2.Run main SQL to retrieve rows
| |
| 3.Multicast
| | |
| | 4.Create footer row by doing sum() in aggregate task
| | |
| 5.Merge body and footer
| |
6. Merge header with body and footer
|
7. Create fixed width file

Hi all,
I am redirecting the critical lookup errors to the flat files. These flat files got created regardless if there are lookup errors or not.
Is there a better way to conditionally create them only when there are lookup errors?
Thanks.

Is there a better way to do this?
We've all seen this, where it uses an individual .write statement for each column.
Code Snippet
Public Overrides Sub AWCCogent_ProcessInputRow(ByVal Row As AWCCogentBuffer)
With textWriter
Dim item As Object
If Not Row.AddressID_IsNull Then
.Write(Row.AddressID)
End If
.Write(columnDelimiter)
If Not Row.City_IsNull Then
.Write(Row.City)
End If
.WriteLine()
End With
End Sub
But hard coding this seems not the smartest way. Especially since in my text file, there needs to be close to 100 columns. This could be a nightmare to update down the road. But I can't seem to find the object collection to loop through, like row.items which would seem to be logical.
There's gotta be a better way, right Microsoft?

I am new in T-SQL. I have just create a empty database and would like to create some table in it. So I type the following in SQL Query Analyzer:
CREATE TABLE mydatabasename.mytablename (
some code here
)
But when execute, it give me an error from the first line "Specified owner name 'mydatabasename' either does not exist or you do not have permission to use it."
when I remove mydatabasename it inserts the table in to the master database, not in my database.
How can I insert the table into my database? Should I use SQL Query Analyzer or use others program? I 've tried to use the command "create table" in enterprise manager but it immediately give another error, some what like "could not use empty column name ... "
Seem to be too simple question, but I am really appreciate your help

Need to know how I can get the dynamic filename created in the FlatFile destination for insert into a package audit table?
Scenario: Have created a package that successfully outputs Dynamiclly named flat files { Format: C:Test’Comms_File_’ + ‘User::FileNumber’+’_’+Date +’.txt’
E.g.: Comms_File_1_20150724.txt, Comms_File_2_20150724.txt etc} using Foreach Loop Container :
* Enumerator Set to: “Foreach ADO Enumerator” with the ADO object source variable selected to identify how many total loop iterations there are i.e. Let’s say 4 thus 4 files to be created
*Variable Mappings : added the User::FileNumber – indicates which file number current loop iteration is i.e. 1,2,3,4
For the DataFlow task have a OLDBSource and a FlatFile Destination where Flat File ConnectionString is set up as:
@[User::Output_Path] + "Comms_File"+ @[User:: FileNumber] +"_" + replace((DT_WSTR, 10) (DT_DBDATE) GETDATE(),"-","")+ ".txt"
All this successfully creates these 4 files:
Comms_File_1_20150724.txt, Comms_File_2_20150724.txt, Comms_File_3_20150724.txt, Comms_File_4_20150724.txt
Now the QUESTION is how do I get these filenames as I need to insert them into a DB Audittable. The audit table looks like this:
CREATE TABLE dbo.MMMAudit
(
AuditID INT IDENTITY(1, 1) NOT NULL,
PackageName VARCHAR(100) NULL,
FileName VARCHAR(100) NULL,
LoadTime DATETIME NULL,
NumberofRecords INT NULL
)
To save the Filename & how many records in each file in our Audit Table, am using an Execute SQL Task and configuring it as this:
Execute SQL Task
Parameter mapping - Mapped the User Variable (RecordsInserted) and System Variable( PackageName) to Insert statement as shown below
SQLStatement: INSERT INTO [dbo].[MMMAudit] (
PackageName,NumerofRecords,LoadTime)
(?,?.GETDATE)
Again this all works terrific & populates the dbo.MMMAudit table as shown below BUT I also need to insert the respsctive file name – How do I do that?
AuditID PackageName FileName NumberOfRecords
1 MMM NULL 12
2 MMM NULL 23
3 MMM NULL 14
4 MMM NULL 1

I have a ssis package where I need to have excel destination. In the Excel file, I need to have few rows with some text and then populate data below the text. One the text is like this:
Data as of: 08/25/2015
if the report ran today, then Data as of will have Yesterday. So, if the user opens that excel file after a week, then user should see same Data as of: 08/25/2015. not today()-day(1).
I was planing to handle on excel side with today()-day(1). but it only works the day it was run. Then the excel file is open after few days later, then it might as Data as of: 08/30/2015 which is not true. It should still stay Data as of:
08/25/2015 on what ever date the excel file is open. The SSIS package runs only once.
How do I handle this so that whenever user open the file, they will see Data as of: 08/25/2015. This is not a column in excel. It is like a description of data in excel.

I am having an issue with the File System Task.
I was wondering if there is a way to 'Move File' with the File System Task inside of a For Each Loop container but to dynamically set the Destination path variable.
Currently, this is what I have:
FileDestinationPath variable - set to C:TestFiles
FileSourcePath variable - set to C:TestFiles
FileNameAndLocation variable - set to blank
For Each Loop Container Iterates through a folder C:TestFiles that has .txt files in it with dates in the file name. Ex: Test_09142006.txt. Sets the file path (fully qualified) to the Variable Mapping FileNameAndLocation.
Script Task (within For Each Loop, first step) Sets the FileDestinationPath to the correct dated folder within C:TestFiles. For example, if the text files I want to move are for the 14th of September, it takes FileDestinationPath and appends the date folder to the end of it. The text files have a date in the file name (test_09142006.txt) and I am picking this apart (from FileNameAndLocation in the For Each Loop) to get the folder date. (dts.Variables(User::FileDestinationPath?).Value = dts.Variables(User::FileDestinationPath?).Value & ? Month & _? & Day & _? & Year & ?) which gives me C:TestFiles 9_14_2006?.
File System Task (within For Each Loop, second step) This is where the action is supposed to occur. I want it to take the FileDestinationPath and move the FileNameAndLocation file (from the For Loop) into this folder for each run.
Now as for my problem. I want this package to run everyday but it has to set the FileDestinationPath variable dynamically according to that days date. Basically, how do I get this to work since I cant hard code the destination path variable from the start? I have the DestinationVariable on the File System Task set to the FileDestinationPath variable, after the script task builds it. However, using FileNameAndLocation as the SourceVariable on my File System Task tells me that the Variable FileNameAndLocation? is used as a source or destination and is empty.?
Let me know if I need to clarify further...I may be missing something very simple. Any help would be greatly appreciated!

I have a number of DTS packages I am trying to convert and am totally new to Integration Services.
I have a flat file that I reference to get a date that I use in some SQL statements in the package. It seems like the best way to do this would be to create a variable to hold the date and set it at run time from the flat file. I've been searching the documentation and the forum and can't figure out how to do this. This is so basic that I feel like an idiot putting it on the forum but I need some help. This whole Integration Services thing is a big shift from DTS (which I eventually became pretty good at) Now I'm back to ground zero.
Any help would be appreciated. If you can direct me to any basic training resources that would be cool too.

Hi all:
I've have a data flow task where I'm importing data into a SQL Server table. All of the fields are mapped, and the source table does not have the uniqueidentifier column (and the destination table will have a uniqueidentifier column). How do I generate a uniqueidentifier for that column without specifiing a default value in the database design? Or is that the only way to do this?
Thanks...

I want to do the following in a package:
Create a table at the beginning of a package (using a ExecuteSQLTask component) and then use the created table as a OLE DB destination component, later on the package.
Is this possible in SSIS?
The problem I run into is that I have to point the OLE DB destination component to a table and set up mappings, however as the table does not exist until the package is running, it does not seem to be possible.
I've looked at:
http://blogs.conchango.com/jamiethomson/archive/2006/11/19/SSIS_3A00_-Using-temporary-tables.aspx
Which is slightly similar to what I want, but the table I create would not be a temp tables, and I need to set up mappings and I don't see how this is possible.
Thanks

Hi,
I've seen a number of posts similar to this but i still cannot figure out what i need to do to get it working. So here goes with a couple of newbie questions.
Question 1:
Once created how do i go about executing a SSIS package. I want to be able to call it from a C# application from which i pass in a couple of parameters?
Question 2:
How do i go about setting the file path of my Excel source to a dynamic value passed at runtime. I want to be able to loop through a number of Excel files and do some processing on them. I've set up a variable (which i think i need to do) after that i get stuck however. Some other posts suggest configuration packages but i cannot get my head around how they work?
Any help on this matter would be gratefully recieved.
Thanks in advance,
Grant

HI,
I'm programmatically able to import data between tables when the Destination table already exists but when Detination table has to be created on the fly (Name will be provided), I'm not successful in doing so.
Basically the requirement is to dump the resultset from the source in to a temp table so that the temp (Destination) table matches the Source's Schema exactly.
Has anybody done that?
Any help in this regard is greatly appreciated.

Hello. I am attempting to add a distribution database to an instance of SQL Server on my local PC. I am using SQL 2005 Developer Edition. I am able to set the instance up as a distributor using the following command:
exec sp_adddistributor @distributor = N'computernameinstancename'
I use the following command to create the distribution database:
exec sp_adddistributiondb @database = N'distribution', @data_folder = N'C:Program FilesMicrosoft SQL ServerMSSQL.2MSSQLData',
@data_file_size = 4, @log_folder = N'C:Program FilesMicrosoft SQL ServerMSSQL.2MSSQLData',
I get the following error when executing that command:
Msg 14430, Level 16, State 1, Procedure sp_adddistributiondb, Line 214
Invalid destination path C:Program FilesMicrosoft SQL ServerMSSQL.2MSSQLData.
It's not due to permissions on that particular folder. I have tried using other folders, all with the same results. Also, I am an Administrator on the PC, so I have full permissions. I have tried running the SQL Server services as myself and Local System. Same results both times. Co-workers with apparently the same setup are able to create the distribution database without a problem.
Has anybody had this type of problem?
Thanks,
Evan

I need to add the current date to the end of the filename of a flat file at runtime.
This was previously done with ActiveX script in SQL Server 2000.
oConn = DTSGlobalVariables.Parent.Connections("FlatFileConnectionManagerName")
oConn.DataSource = sNewFileName
oConn = Nothing
I would really appreciate if someone could give me some information on how to achieve this in SQL Server 2005.

I have been working with flat file connection managers for a while now, and I have found it very useful to set properties on all types of SSIS objects using expressions that are set to SSIS package variables.
We have recently moved towards using a centralized application configuration infrastructure, so we are now loading up all application configuration information from our own system -- it's actually based off of the 2.0 ConfigurationManager.
I have developed a custom control flow task that will retrieve all of the SSIS variable information from our own application configuration system and set all of the SSIS variables as the first step in a package.
When I have been using this to set the SSIS Variables which are used in expressions for the HeaderRowsToSkip and DataRowsToSkip (there may be others, but I have not tested them yet) properties of flat file connection managers, these values are not being used -- instead it is using the values for the variables that are defined in the package itself (i.e. the default values that I set up in BIDS when developing the package). The ConnectionString property on the flat file connection manager does not exhibit this behavior.
Can anyone provide any insight on this? Is this a bug in SSIS, or is there something that I am missing here?
Thanks in advance.

Hi,
I am testing SSIS and have created a Flat File Destination. I defined the Flat File Connection as New for the first time and it worked fine. Now, I would like to go back and modify the Flat File Connection in the Flat File Destination Editor, but it allows only to create a New connection rather allowing me to edit the existing one. For testing, I can go back and create a new connection, but if my connection had 50-100 columns then it would be an issue to re-create it from scratch.
Did someone else faced this issue?
Thanks,
AQ

Hi all
I have a flat file.I am trying to set the value for the property "HeaderRowsToSkip" during runtime.I have set an expression for this in my "flat file connection manager". But this is not working.The connection manager is not able to take the value during runtime.
My expression is as follows:
DataRowsToSkip : @[user:: Var]
where "Var" is my variable which gets the value from the rowcount component and trying to set it back to the "HeaderRowsToskip" property.
I ve even tried setting the value to the "HeaderRowsToSkip" property in the expression builder.
Its not working....
Can anyone help me out in solving this????
Thanks in advance

I am transferring data from an OLEDB source to a Flat File Destination and I want the column width for all of the output columns to 30 (max width amongst the columns selected), but that is not refected in the Fixed Width Flat File that got created. The outputcolumnwidth seems to be the same as the inputcolumnwidth. Is there any other setting that I am possibly missing or is this a possible defect?
Any inputs will be appreciated.
