SSIS-problems Making A Dynamic Flat File Connection String
May 8, 2007
Hello.
I have packages that must generate log errors dynamically including time of execution and the name of the task.
I make it changing the properties of the connection inserting two expressions.
1.-I alter the File Usage Type to 1 to generate this files.
2.- I alter the connection string as: @[User::myvariable] +"constant_description"+ time description+ +".txt"
The time description is :
(DT_STR,40,1252) DAY (GETDATE())+"-"+(DT_STR,40,1252) MONTH( GETDATE())+"-"+(DT_STR,40,1252) YEAR( GETDATE())+" + REPLACE( (DT_STR,10,1252) (DT_DBTIME) GETDATE(),":","_")
But it is not the problem
In those packages I have one connector for all the tasks and in execution time it creates one file for each of the tasks.
The problem is the way I insert in the filename the task name.
I have a pre-execute event handler in each task that modifies a string variable( myvariable) appending the task name. When I execute de package it works great but when I only execute a task, the program do not enter in the event and do not put the tasks name.
How can I put that name without using that handler? There is another handler can I use to do it that happens before the system generates the new file name and after pre-execute? Anyone knows another way to do this kind of things?
I have a simple package, which reads a flat file source, does some transformation, and outputs to a flat file destination. The package runs as a SQL Agent job, so I have the flat file source and OLEDB connection ticked and configured on the data sources tab.
What I would like to do is get hold of the flat file source connection string property from inside the package at run time, and use it to set the flat file destination connection string using property expressions.
The easy option is to set the destination in the agent job, but I'd like to add a date/time stamp to the destination filename.
Hi, I tried to follow the widely talked about method to dynamically populate the connection string property of my flatfileconnection manager from a variable. I keep getting the following non-fatal error.
TITLE: Microsoft Visual Studio ------------------------------
Nonfatal errors occurred while saving the package: Error at Package [Connection manager "FFCM"]: The file name ""C:ProjectsSSISHLoadTOutputOut.csv"" specified in the connection was not valid.
Error at Package: The result of the expression "@[User::CsvFullFileName]" on property "ConnectionString" cannot be written to the property. The expression was evaluated, but cannot be set on the property.
Here is what I am trying to do. I have a foreach loop that iterates through a list of xml config files and reads the config information including the destination csv file name and does a data transformation. So I created a flatfile connection to a csv file did my data mappings. Created a package level variable to hold the destination file path In the Flat file conn. manager's properties -> expression -> set the @[User::CsvFullFileName] (which even evaluates fine)
When I try to run the package I keep getting the above mentioned non-fatal error..I checked the path and it is valid. I even tried
the c:\projects\...notation and the UNC path notation...all seem to give the same error
Anyone experience this before ? any thoughts would be appreciated.
Another question regarding the frustrating SSIS stuff. Basically when I used to use a DTS task to import a flat file (comma delimited) into the database it worked fine no problems, however, for some reason the same approach in SSIS means that any string values in the file are automatically delimited with double quotes, even though I am specifying <none> as the delimitation. I have also changed the fields so that the the TextQualified is set to false.
This causes a problem because all of the information stored in the database (done by a stored procedure) contains these stupid quotes.
Is there something I am missing or haven't done correctly to get rid of the quotes
My task is to read the filename from a database table and transfer the flat file data in to a table. In SSIS,I am able to fetch the file name using a Data Reader Source; but how to pass this fileName parameter to Flat File Source ?
In DTS I have used ActiveX script to pass filename variable as flatfilecon.Source. Any help ?
Hello Experts, I am createing one task (user control) in SSIS. I have property grid in my GUI and 2 buttons (OK & Cancle). PropertyGrid has Properties like SourceConnection, OutputConnection etc....right now I am able to populate Connections in list box next to Source and Output Property.
Now my question to you guys is depending on Source Connection it should read that text file associated with connection manager. After validation it should pick header (first line of text file bases on record type) and write it into new file when task is executed. I have following code for your reference. Please let me know I am going in right direction or not.. What should go here ? ->Under Class A
. . . . I am specifying the row delimiter as : </row>{CR}{LF}<row> When I create Flat File Connection and when I see the preview of columns...in the first row "<row>" remains and in the last row "</row>" remains...
I am trying hard to sort out and remove these extra string but unable to do so...
Please let me know how to approach this? How should I specify the Row Delimiter?
Requirement: When we create SSIS Pacakge using Businessinteligence studio.Each Source and Destination or whatever we using the Control required DB Connection.
we connect theDB server and Database Table through manaully .Instead of Manual i need dynamic Global varible for Connection String .How to achieve this connection string.
because suppose we create SSIS Package in Developement Server Latter We change the Server from Developement to Another Testing Server . at that time we dont requierd for changing manulay.any one pls reply me.
Same as in Dotnet we give configiration XML file .we gave the Connection strng. how to in SSIS we do?
Im using the Flat File Connection Manager to access a flat file, tab delimited. The flat file has 200 columns, and when I'm editing the columns, I only preview columns from 0 to 97.
Does the flat file connection have a column number limit? How could I increase it?
Hi, I got this error in a Flat File connection manager, it was saying that the last column caused the disk I/O Buffer overflow, whereas the last column contains 188 characters at max.
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.
Note that the third column in the third line is also qualified by quotes whereas the previous two are not. I think this is because of Excel formatting. Is there any way to import this file correctly?
My main problem is that I never know whether a column will be qualified or not because this depends on the value. I need to loop through and import many of these files so a manual workaround is not a option for me.
I have a situation where a tab limited text file is used to populate a sql server table.
The tab limited text file comes from a third party vendor. There are fixed number of columns we need to export to the sql server table. However the third party may add colums in the text file. Whenenver the text file has an added column (which we dont need to import) the build fails since the flat file connection manager does not create the metadata for it again. The problem goes away where I press the button "Reset Columns" since it builds the metadata then. Since we need to build the tables everyday we cannot automate it using SSIS because the metadata does not change automatically. Is there a way out in SSIS?
I'm a newbie to SSIS so this question may cause people to point and laugh. I apologise if that's the case.
I have a configuration database that holds connection details to a remote database. I want to use these connection details to dynamically create a new connection to some remote database.
I usually work in with C# where this would be simple but I can't find how to do this using SSIS.
I have found people using configuration files but as I already have my connection data in a table I don't really want to strip it out. (Also, is it a security risk to have database connection strings stored in a config file?)
I have been able to implement a custom script object to build the connection string and assign it to a user variable within the package but can't find any way to then use that variable to connect to the remote database.
Hi, I have installed on my laptop SQL server 2005 Developer edition, I can change ANY of the settings of the SQL server and OS.
I am writing code with a team using continuous integration where the connection string is the following: "Provider=SQLNCLI;Server=.SQLEXPRESS;Database=Secret;Trusted_Connection=Yes;"
is there a way (create an alias,rename server, other?) to make my local dev SQL server accept the connection string above, as at the moment I have to rename the connection string every time before checking in code and after downloading the latest version from the code repository.
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:
I am trying to create an ssis package with dynamic csv file as output. and out format contains query output.
sample file name:
Unique identifier + query output + systemdate();
The expression is looking like this.
@[User::FilePath] + @[User::FileName] + ".CSV"
-- user filepath is a variable from ssis package. File name is the output from SQL query. using script task i have assigned the values to @[User::FileName] .
When I debugged the script task the value getting properly but same variable am using for Flafile destination. but its not working.
I have dozens of packages that work as follows (high level... not listing all the steps just those relevant to this question)
- Get list of files in directory
- Join list to list of already imported files
- Those not imported put into an ADO.Net object
- Loop through ADO.Net record (which contains the filename) and import each file.
I just set the connection string of the flat file to be the variable in the loop (expressions.. connection string). Pretty standard stuff. Now I tried to do the same with a file connection (not a flat file) becuase I have a source that is from a mainframe and I had to write a custom source script and its not working. Basically the source script uses
And it opens the same file over and over (not ever changing as the ConnectionString expression changes like it does for flat files) and imports it even though I have verified the loop is correctly looping through all the different files.
I'm trying to read the folder which has flat files and transform it and put it another folder with the SAME original name. I created a For Eachloop containter and assign it to variable infile. In the data flow I added some transform and flat file destination. currently its reading 3 files and output is only one file. I would like to create dynamic flat file connection so that it'll create separate files (same name) in different folder. Thanks,
Say I am going to write to a different Flat File for every product. So if there are 10 products in the data. There should be 10 Flat Files. Also the file name should include the Product Name And Product ID.
It is being done in a single Data Flow Task.
Right now the Property Expression for the File Name is which is not working)
I'm new to SSIS. I have a small problem. In our system we are trying to create flat files based on data from returned from different SQL stored procedures. The configuration settings for creating the flat files are stored in a SQL table.
For example, the config table will look like below :
Feed Id Feed Name Feed File Name Feed Stored Procedure Name ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 1 Biz C:Biz.txt dvx_GetBiz 2 PG C:PG.csv dvx_GetPG 3 NexT C:NexT.txt dvx_GetNexT 4 Amez C:Amez.csv dvx_GetAmez
The problem is dvx_GetBiz, dvx_GetPG,... all have different number and types of columns. So, I'm not able to create a dynamic Flat File destination depending on the columns returned from the corresponding stored procedure.
I am writing a package where the user uploads a flat file to a web folder. I need to automate this package to run everytime it sees a new file.
How can I implement this?
Can I make a call to a package or a sql server job to run from .net 2.0?
Do I need to use a service broker to look for a new file and run the package or a stored proc....I am looking for an async process where user doesnt have to wait for the package to run as it involves data validation of flat file and its huge...
Problem: ColA (Source) Rounding error to PARTY_NO (Destination) I have a field of text of in a flat file that the flat file connection manager Source picks up correctly 70000893? However when it gets the OLE DB Connection Destination the data has changed to 70000896. Thats before its even Written to the database. The only clue that something is wrong in the middle is the great Data viewer shows the number as 7.000009E+07 Other clues looking at the data it appears there is a rounding error on only the number that dont end in 00 ColA (Source) PARTY_NO (Destination) 71167300 71167296 70329000 70329000 70410000 70410000 Any ideas people? Thanks in advance Dave
I have number of csv files in a folder, all of them with same columns, need to be merged into one table and imported to sql server.
-The first row of the csv file is a header. -The csv files are updated everyday -The destination table is replace by new table with new info in the csv. -The new csv files can be created and old csv files may no longer exist, but we are only interested in information contain in current csv files in the folder. -I need SSIS to combine all the csv files in the folder and merge into one table. -Other issue is that the field names may change in csv, so can the SSIS package recognize the change in field name and made necessary change in destination table as well.
Any insight on this issues will be greatly appreciated?
I have a database app, and we're implementing various data export features using SSIS.
Basically, it's a couple of straight extracts of various recordsets/views, etc. to CSV (flat files) from our SQL Server 2005 database, so I'm creating an SSIS package for each of these datasets.
So far, so good, but my problem comes here: My requirements call for users to select from a list of available columns the fields that they want to include in their exported file. Then, the package should run, but only output the columns specified by the user.
Does anyone have any idea as to the best way to accomplish this? To recap, at design time, I know which columns the users will have to choose from, but at run time, they will specify the columns to export to the flat file.
Dynamically load a flat file from a dynamic source table-
The source table metadata is known via the SYSOBJECTS and SYSCOLUMNS tables- I can pull the column names, type and lengths from these tables based on the table name. (my goal is pretty simple- pull data from a table in our database, and save it down to a flat file)
Would this be enough to dynamically create the destination flat file? If so, how do I do it?
I will be receiving a CSV daily where columns within the file will change. The column order and number of columns can change daily. I need a way to read in the header from the csv and create a flat file connection that reflects the columns listed in the header.
Is there an easy way to do this using a script task? I have already read the header into a table but I have been unable to create the dynamic file connection.
We were able to use a dynamic connection string in the report designer, but once we deployed to the report server we are getting the following error: Error during processing of the ConnectString expression of datasource Dynam. Has anyone experienced this, and how did you fix it?
Our Reporting Services environment uses Oracle as the data source. Based upon the user connecting to the database determines what rows they will see for various tables. How can we dynamically pass the username/password to the connection string? Background: Our users log into Active Directory and are assigned to a group. The AD group name is used to access a control table in Oracle that contains the database username/password for that groups connection to Oracle. All subsequent connections to Oracle will use the groups username/password from the control table. We have an ASP.NET application that works like this and stores the connection information in the session state. How can we do something similar with our connection in Reporting Services? Note: Our Oracle Database does not use Windows Integration.
