How To Store Column's Value From A Flat File Into A Package Variable?
Oct 7, 2007
I have a few flat files that will be retrieved from some SFTP server. One of the flat file will act as a terminal file where it will specify the total number of records expected in each other the flat file.
Data in the terminal.txt
FileName TotalRecords
File1 1000
File2 1500
File3 2000
So, before transforming the data from the flat file sources into the target destination, i wish to do a row count checking for each of the flat file source to make sure that the number of records in the flat file source is tally with the number of records specify in the terminal.txt file. I'm able to get the number of records in each of the flat file by using the RowCount component but don't know how to get the data out from the terminal.txt file in order to make a rowcount comparison.
Can any1 help me on this? Or is there any other way we can do to make sure that the flat file source is alright before proceeding with the data transformation task?
After the staging_temp data gets inserted into main table.my probelm is to handle such a file where number of columns are more than the actual table.
If you see the sample rows there are 4 column separated by "¯".but actual I am having only 3 columns in my main table.so how can I get only first 3 column from the satging_temp table.
Public Class ScriptMain Inherits UserComponent Dim smpid As String Dim Prdt As String Dim rcnt As Int64
[code]...
Using the Vb script above I am expecting to read the first row from a flat file source and transferring the data into two variable using script component.
I get the following errors one after the other:"The collection of variables locked for read and write access is not available outside of PostExecute." "Object reference not set to an instance of an object."
I am creating one SSIS package where my source is oracle. I have transferred the data from Oracle to flat file as per client requirement.I have to create single package for 2 country 1 is US and another is CANADA Columns are below
ZONE_ID, ZONE_NAME Zone Id having data like 10001,10002,10003,20001,2002,2003
Where zone_id start with 1000 is US Zone and Zone_Id start with 2000 is Canada Zone.
For US: 1. Load geography data from DB tables into flat files 2. Load geography data from flat files to Spectrum DB tables
For Canada: 1. Load geography data from DB tables into flat files 2. Load geography data from flat files to Spectrum DB tables
Now I want to look from flat file if Zone_id start with 1000 then it must go to US_DFT and if Zone_id start with 2000 then it must go to CANADA_DFT.
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 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?
I am transferring data from msaccess to sql2005 using foreach loop. I have a table called Students and a column in it called State.
I want to store the value of the State in a variable in the foreach loop. I am using Dataflowtask to transfer rows from access to sql. what component can i use inside dft to store the value of State in a variable.
I have a simple CSV/XLS dump that i need to put up on the server. I would need to create a file output daily and need a variable name to identify them easily. I have the problem of naming it in the "connection string" easily and i have tried variables and expressions too. I am new to this so please need help. Thanks
As part of auditing of our application, I want to write the values of all column in one row out to an audit table both before and after an update to see what the changes were.
I know I can SELECT * FROM tableName FOR XML AUTO to generate a single XML 'column', but I cannot figure out how to capture that output and store it.
According to MS, you cannot use FOR XML in a subselect, or fill a TEXT variable with the results of such (which, IMHO really diminishes the usefulness).
I want to stream out the results of one entire row and store that in ONE column of an audit table. XML seems like the easiest way if not for this limitation.
How can I write the value of a variable to a flat file in SSIS?
In particular, I'm creating a flat file I'm storing the data of a table. I'd like to add a header that displays the value of a variable that contains the record count. How can I do that?
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.
I am trying to make a SSIS package that will loop trough all files in a directory and load information from them.
I can do this with Raw File Sources since they allow me to use a variable name as the file path, but I cant seem to do the same with Flat File Sources. Is there a way to change the connection to a Flat File Source on each iteration of a loop? Actually, if this is possible with all types of file sources (like excel files) I would love to know about it too.
I was thinking about renaming the file through a script task but that does not seem like the most elegant solution so decided to see if some one here knows of a more proper way before I go that direction.
I'm relatively new to SSIS and I've been tinkering with the XML and Flat File sources.
I noticed that in the XML source it is possible to tell SSIS to read the XML data from a variable. I didn't see a similar option for the Flat File source.
Does anyone know if it is possible to read flat file data from a variable when using the Flat File source?
Okay, can I assign line x of a flat file to a variable, parse that line, do my data transformations, and then move on to line x+1?
Any thoughts?
In other words, I'm looking at using a for loop to cycle through a flat file. I have the for loop set up, and the counter's iterating correctly. How do I point at a particular line in a flat file?
I have a variable defined as "Country". Based on the value, the header row printed needs to be different.
I've already created a 'HeaderRow' variable that I'm able to set using a script task. But how can you set the Header text value at run time from the variable? There is no expression defined for the Header with the Flat File Destination object, and when I attempt to reference the HeaderRow variable as the Header text, the variable name is printed as the header.
Another approach I tried was to write the Header Row separately through another data flow task, but the issue here is: what is the input source when all you have is a Country variable?
I'm doing a simple ETL that reads a database table and dumps the content to a text file. The text file will be named Employee.txt. This file name will remain the same across my environments, but I may want to vary the directory location to where I want this file dumped.
So, I defined an environment variable called "DataTargetDir" in all my environments. Now, I want to utilize this variable in the "File name:" box within the Flat File Connection Manager Editor. How do I do this? I'm thinking I can write something like "%DataTargetDir%Employee.txt" in the "File name:" box, but it's not working.
Hi everyone, I am using SSIS, and I got the folowing error, I am loading several CSV files in a OLE DB, Becasuse the file is finishing and the tak dont realize of the anormal termination, making an overflow. So basically what i want is to control the anormal ending of the csv file. please can anyone help me ???

Ok everybody. I am new to sql. I have ms sql staging database that pulls data from mysql database. Then once a day I run a ssis package that moves the data to a live database and also creates a flat file that is posted to a ftp site then truncates the table. One problem I am running into is if the mssql staging database has no records the flat file is still created. How do I stop it?
During my development of a ssis package i've noticed that when creating two control flows that pulling data from seperate tables, each going to its own flat file, that the second keeps the attributes of the column names from the first. So when I create my second flat file, not only does it have the names of its correct columns but has the name of the the first flat file.
I'm hoping that I've explained the correctly. I'll provide more info "OR" I can provide the code to package if anyone would like.
I have a requirement wherein I have to setup the flat file connection manager to accept columns on fly. Meaning I want to retrieve list of columns/column count from the database when the package is run and set the connection manager with those many columns.
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 ?
I am writing a package that will process delimited flat files that will come in one of a few different versions. Within each flat file, the number of delimited columns will be the same, but each version of the file has a different number of columns. I have tried configuring the flat file data source to expect the version with the largest number of columns, but it will then throw away rows that have less than this number of columns (warning: There is a partial row at the end of the file).
Is it possible to use a single flat file data source that will work with all of the different width files?
Trying to figure out the best method of reading in a number of flat files, all with different number of columns and data types and outputting them to a database.
Here's the problem: They are EBCDIC encoded and some of the columns are packed decimal. I've set up one package that takes the flat file, unpacks the decimal (Using UnpackDecimal component) and then sending the rest through a second component to go from EBCDIC -> ASCII.
What I need is a way to do this for every flat file based on the schema for that flat file. One current solution is to write a script/app to create the .dtsx XML file and then execute that for each flat file. It appears like this may be possible, but I haven't gotten far enough to know for sure. So my questions are this:
1) Is there an easier way to do this (ie somehow feed the schema to the package and use it to dynamically set up the column makers and determine which columns get fed to the unpack decimal component.
2) If there isn't a better way, will dynamically creating the .dtsx XML file based on the necessary input/output columns for each flat file work? If so, what is a good source of information on this (information about how the .dtsx XML file is set up, what needs to be changed/what doesn't, etc).
I have a package set up basically with two consecutive data flows. The first flow takes data from an OLE DB Source and stores it into a Flat File Destination. The second flow uses this same flat file as a source, alters the data, and stores the data in the same flat file, overwriting the old file. I set DelayValidation to True on the flat file. Still, here are the error messages I am receiving:
Error: 0xC020200E at DO, Flat File Destination [7676]: Cannot open the datafile "C:Temp.txt".
Error: 0xC004701A at DO, DTS.Pipeline: component "Flat File Destination" (7676) failed the pre-execute phase and returned error code 0xC020200E.
I am new to SSIS, so I'm sure I have a setting wrong or something. Is the problem that SSIS is trying to write to a file from which it is simultaneously reading data?
There is a small problem encountered while creating a package in sql server 2005. Actually i am using a flat file which has 820 rows and 2 columns which are seperated by line feed(for ROW) and tab(for COLUMN).after importing i found that ther are only 800 rows imported into the table. Ather verifying the input file i found out that there are some null values in the second column so there is no line feed for those values. Can anyone please help me how to give multiple delimiters for the same input flat file.
I want to make a very simple package: Export all rows in a table to a flat file. This package I can create pretty much by only using the wizards. Now to my problems:
H is a header post, in this case with date and time following. D is a details post, that is all the rows that was exported. E is and end post, containing only the number of rows in the file, including H and E posts.
2) I need to set the file name dynamically, preferably using date and time to name the file.
I´ve done this very same thing in T-SQL, like so:
Code Snippet USE AVK GO SET TRANSACTION ISOLATION LEVEL SNAPSHOT; GO SELECT * FROM tempProducts GO CREATE VIEW EXPORT_ORDERS AS SELECT 1 AS ROW_ORDER, 'H' + REPLACE(CONVERT(char(8), GETDATE(), 112) + CONVERT(char(8), GETDATE(), 108), ':', '') AS Data_Line UNION ALL SELECT 2 AS ROW_ORDER, 'D' + COALESCE (CONVERT(char(10), LBTyp), '') + COALESCE (CONVERT(char(50), Description), '') + COALESCE (CONVERT(char(5), Volume), '') AS Data_Line FROM dbo.tempProducts UNION ALL SELECT 3 AS ROW_ORDER, 'E' + RIGHT('0000000000' + RTRIM(CONVERT(char(13), COUNT(*) + 2)), 11) AS Data_Line FROM dbo.tempProducts AS tempProducts_1 GO IF @@ROWCOUNT > 0 BEGIN BEGIN TRANSACTION SELECT * FROM tempProducts DECLARE @date char(8) DECLARE @time char(8) DECLARE @sql VARCHAR(150) SELECT @date = CONVERT(char(8), getdate(),112) SELECT @time = CONVERT(char(8), getdate(),108) SELECT @time = REPLACE(@time,':','')
DECLARE @dt char(14) SELECT @dt = @date + '_' + @time SELECT @sql = 'bcp "SELECT Data_Line FROM avk..EXPORT_ORDERS ORDER BY ROW_ORDER" queryout "c:AVK_' + @dt + '.txt" -c -t -U sa -P dalla' EXEC master..xp_cmdshell @sql
--WAITFOR DELAY '0:00:10'; DELETE FROM tempProducts
COMMIT TRANSACTION END DROP VIEW EXPORT_ORDERS GO
But I´m sure it can be done in SSIS aswell, giving me some nice options for i.e. error handling aswell. Pointers please
hi, on an oledb destination, I want to map one column from a flat file source object to two different columns on the database table. I only seem to be able to map one to one. How do I get the pointer to attach to two destination columns?
I am working in one company and currently I am assigned to new project for Data Migration from company X to our company Y using SSIS. I am totally new and i just completed 5 tutorial which was gien on MSDN website.
Basically client is going to send us first flat file with 1 million records with Header, Detail and Trailer records. I want to create a Package in such a way that it dumps all this first load into 7 to 8 different tables at a time. we also have to include functionlity for validation and error check. On successfull load error file should only return Header and Trailer but no detail records. If there are any errors then error file should contain Header, Detail records which were unable to load plus trailer which we have to sent back to client.
When 2nd file comes that time we have to check whether this is new records or change (update) one depending on Flag which tells it.
This is basically high level idea of my Package what i need to create. If u guys have any question then let me know.
I know you guys are very experienced one. Anyone of you please give me some detail idea on it I would really appricate it. I have very limited time line for it.
I am having frustration with issues I'm seeing within Development Studio. Here's the problem:
A fixed-width flat file is to be imported into SQL 2005. I am running from within BIDS on my workstation and send the data remotely to the server. It has over 200 fields, and I am attempting to import them into dimension tables, and one fact table. I had to manually create the columns on the flat file connection manager for this process, since the data file is delimited.
The SSIS solution has one project, and several independent data flow tasks within it. After I set up the fcm, I mapped fields using a flat file source, hooked up a derived column and sort transform. The idea was to use a 3rd party tool, TableDifference, to implement a Type 2 dimension. I was able to successfully build three data flow tasks that ran correctly. Later, as was building new data flow tasks, our project people decided to change the data types of several of the fields from Datetime to character, and also rename another 40+ fields. I dutifully kept my fcm synchronized, since column mappings are automatic when the names match; data type changes were also unavoidable on some of the columns.
The problem was noticed after I changed some of the columns in the fcm. My flat file source adapters on all the tasks needed to resolve changed metadata so I had to 'edit' and save them again. The derived column, sort, and downstream transforms also had to be updated. I saw strange behavior on previously tested data flow tasks. Some of them gave me errors even connecting to their sources. Other times I saw erroneous paths being taken which led to data being changed incorrectly on the dimension tables (new records being added even if there was an existing match, records being marked as expired incorrectly, etc.).
Are there known issues with editing a shared file connection manager after it has already been referred to within data flow tasks? It appears that the only way to avoid the problems I've seen is to either:
1. Create separate fcm's for each data flow task. Use 'filler' fields for the ranges of all the columns in between each referenced column. This way if you have to change anything with it, the only rework involved is limited to the data flow task using it.
2. Create one fcm for the entire package and NEVER change anything with it. If a column name is wrong, use a derived column to rename it in the data flow. If a data type changes, try to use a data conversion transform, but be sure to rename its output column so that it is not called 'data conversion.<field name>'. I think that's done in the Advanced Editor for the sort task.
My experience using BIDS has been hot and cold. It's nice to be able to quickly build the tasks you need, but it's as if the metadata (pipeline) is much too sensitive to change and requires a lot of touching up, either upstream at the source adapter level, or across data flow tasks when you make changes to the FCM. Maybe the problem is just limited to flat files...
Are there any tips or lessons learned from anyone on this? I've got another developer willing to create the FCM for other data feeds so I can copy/paste them into other projects. It would just be nice to know there was a bug fix or a good method to avoid all this 'rework' when you have to make changes to the FCM after the fact.
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.
