SSIS: Set Header Printed When Writing To A Flat File From A Variable
Jun 13, 2007
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 unable to figure out how to write a column header to my flat file destination. My source is a OLE DB SQL query and I need the column names as a header row in my text file destination. This seems easy but the closet I can find is hardcoding the column header row in the header property. Is this the only option?
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 ?
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."
How can I take this example Flat file and parse out each section to a new flat file? Each section starts with HD (header row)
http://www.webfound.net/flat_file_example.txt
e.g. an example output file based on above (cutting out the first section) would be:
http://www.webfound.net/flatfile_output.txt
Also, I'll need to grab a certain value in each header row (certain position in the 100 byte header row) to use that as part of the filename that's outputed. I assume it would be better to insert these rows into a temp table then somehow do a search on a specific position in the row...but that's impossible? The other route is to insert each row into a temp table separated out by fields but that is going to be too combursome because we have several formats to determine separation of fields based on the row type so I'd have to create many temp tables and many components in SSIS when all we want to do is again:
1) output each group (broken by each header row) into it's own txt file
2) use a field in the header row as part of the name of the output txt file (e.g. look at the first row, whcih is a header row in flat_file_example. txt. I want to grab the text 'AR10' and use that as part of the filename that I create
Any suggestions on how to approach this whole process in SSIS...the simplest approach that will work ?
I have a data flow task where I have to write to a flat file. It works fine for me. But the thing is next timeI run the package it must write the data in the OLDEB source to a different copy. Usually the data is overwritten or appended to already existing data. What I want is everytime the package is run the data must be written to a different copy.
I have a Foreach loop which scans a table, and gets names of a bunch of procedures, and then back in the foreach loop, they get executed. Im trying to figure out how I can create a sort of log file to say the name of the procedure that is getting executed currently and the current date time stamp onto a flat file. I havent been able to figure this out yet..anyone know how to do this? I grab the names of the storedprocedures from the table and store it in a variable and use the name from the variable to actually execute the stored procedure.
I guess in essence, the question is how do i directly write lines of 'text' (from say a variable) into a flat file.
I'm doing a test package which reads a flat file, makes an adjustment using the derived column task and writes to the same flat file. But, the read locks the flat file, so the write can't access it. Any ideas for a resolution?
i am currently creating a package which involves getting data from CSV files. i can successfully get the data from the files, my problem is, i need to get data from the header of the CSV files. i am currently skipping the header rows. the format of the CSV files is as follows:
----------------------------------------------------------------------------------- Date, 20070704 Store Code, storeCode1
data row..... data row..... data row..... -----------------------------------------------------------------------------------
technically, i also need the date from the header row, but since it is also indicated in the data rows, i have no problem with that. what i need is the Store Code, which is not indicated on the data rows. i need to store the data in a database in the following format:
Basically, Marked Red record stands for Transaction Header, Marked Green records are Transaction Detail 1 and Marked Blue records stands for another Transaction Detail 2.
Now I need to move the data, based on the Record Type ( First Column 2,3,4) If its RecTyp 2 then move into Tran Header table, when RecType 3 then move into Tran Det1 table and finally, when RecType 4 then move into Tran Det2 table.
Anyone could guide how to start this migration.
Note: The given sample is the one set of data in that flat file. Similarly in the same flatfile we have multiple set of data.
Is it possible to have two different formats for the header and the data in a flat file connection?
An example text file would look like this:
Col1,Col2,Col3
abcdefghi12345testtesttesttest
abcdeeeee12333setsetsetsetsets
where the header is delimited and the data is ragged right.
It looks like you should be able to accomplish this from the Flat File Connection Manager Editor interface, but perhaps having different delimiter dropdown boxes for the header and columns can only be used if you are using the Delimited format?
Flat file is the source for to load the data into a table. I am using "Derived Column Component" for the data validation.
"Derived Column Component" Fails then i am writing/redirecting the records into the Flat File using "Flat File Destination" component.
It works fine except the following the issue.
Issue: The derived columun value (that cause an error) is not get inserted into the Flat File
Scenario: the data comes as "000000" and tring to convert to date format (DT_DATE)("20" + RIGHT(Check_Date,2) + "/" + SUBSTRING(Check_Date,1,LEN(Check_Date) - 4) + "/" + SUBSTRING(Check_Date,LEN(Check_Date) - 3,2))
The above expression is working fine, except the data 000000 not passed into the Flat File Destination.
I have a set of parent/child records that need to be exported to a space delimited Flat File. Each parent record must be followed by 3 child records, each on their own line with different format.
I have a prototype using the Derived Column component that concatinates the various fields of each record into one "wide" text column. This fools SSIS to think that each row has the same format. Then I merge them together using an artificial sort id. But this seems overly tedious and very brittle.
What would be the best approach to writing these records out? I'm hoping there is a better more maintainable method.
I would like to write my table to a delimited file but I seem to have no choice but to use comma as the delimiter. Is there any way I can choose the delimiter ?
I am trying to write to a fixed format flat file using Flat File Destination Data Flow Component. I have all required information gathered from more than one sources. But when I tried to format the columns to a big string that will make up one line in the flat file, I could not figure out how to do that. Couple of issues that I am facing are:
How to padd different columns? For example, One interger column has could be 1 to 10 character long in my case. When I convert to string, dont know how to padd the remaining characters i.e. if the value of integer is '1234', it should be written to file as '1234 ' . Which transformation is best in this case, if available? How to convert T-SQL datetime to a specific date and time format to write in the flate file? I have to write these date formats depending upon one of the parameters passed. Also, I dont want to put a delimiter at the end of each column, just the new line characters at the end of each record. Some of the columns has some unwanted characters (like new line characters) how to find them and remove them from the string. Can we directly write columns to a specific position in the flat file? e.g. col 1 a position 1 and col2 starts at postion 20 etc.
I have a tsql script that gets the data I need, into the format I need, and saves it in a format (.output) I needI also have a script that creates a header for the report, basically its just a name and rowcount() that also works fine.PROBLEM: If I combine them using UNION, I have to pad out the header report with NULL columns, and it messes up the layout of the report.Anyone have a simple way to do this?here's my code:SELECT 'A71310000'+ltrim(Str(count(UserName))) + 'HRBATCH' AS header, NULL as col2, NULL as col3, NULL as col4, NULL as col5, NULL as col6, NULL as col7, NULL as col8FROM db_owner.PS_HR_HrsWHERE Reported is NULLUNION ALLSELECT EmplID, Convert(VarChar,DateWorked,111),'STSSH', CAST(REPLACE(STR(HoursWorked,9, 5), SPACE(1), '0') AS nchar(9)), HRAccountCode, CAST(REPLACE(STR(EmployeePayRate,18, 6), SPACE(1), '0') AS nchar(18)), 'A_STUDSUM', HRAccountCodeOverrideFROM db_owner.PS_HR_HrsWHERE reported is NULL What I need it to look like is: A713100007HRBATCH
10068800 2007/06/05STSSH002.00000 A108145 00000000007.500000 A_STUDSUM ...(this is a ragid right with spaces padding out fixed width columns) THANKS for ANY light ANYONE can shed on this.
I can't believe it's been a few days and I can't figure this out. We have a flat file (purchaseOrder.txt) that has header and detail lines. It gets dropped in a folder. I need to pick it up and insert it into normalized tables and/or transform it into another file structure or .NET class.
10001,2005/01/01,some more data SOME PRODUCT 1, 10 SOME PRODUCT 2, 5
Can somebody place give me some guidance on how to do this in SSIS?
I'm trying to extract data from a Flat File which is as fixed length as they come. The file has a header, which simply contains the number of records in the file, followed by the records, with no header delimeter (No CR/LF, nothing).
For example a file would look like the following:
00000003Name1Address1Name2Address2Name3Address3
So this has 3 records (indicated by the first 8 characters), each consisting of a Name and Address.
I can't see a way to extract the data using a flat file connection, unless we add a delimeter for the header (not possible at this stage). Am I wrong?
Any suggestions on possible solution would be much appreciated - I'm thinking Ill have to write a script to parse the file manually.
I have a flat file with header and detail information, it is actually employee punch card data. I need to parse the header line which contains the Employee ID and don't save it to a table just save the value. Then with the detail line, parse the different data elements and save them along with the employee ID to one table. Then continue until the next header line is read.
So I think I need a data flow transformation object that let's me save the Employee ID into a variable available when the next record is read. What type of transformation would be best?
where 'data' represents the data written out by the data flow process to the flat file destination. This actually turns out quite nice except that when I place the lines that start with '/' in the header box for the flat file destination the carriage return doesn't get written correctly after each line and I end up with an unrecognized character when I open the file in a simple app like notepad. I've tried using different encodings for the flat file connection, but to no avail. It is also interesting to note that when I close the package and reopen it the flat file destination editor UI also doesn't recognize the carriage returns and places a box in there place.
Below is a copy of the the property as it is written in the package xml:
<property id="92" name="Header" dataType="System.String" state="default" isArray="false" description="Specifies the text to write to the destination file before any data is written." typeConverter="" UITypeEditor="" containsID="false" expressionType="Notify">/INST=-1 /DELIMITER="," /FIELDS=FIELD1,FIELD2,FIELD3,FIELD4 /LOCATION=100</property>
I have a package that contains three database tables (Header, detail and trailer record) each table is connected via a OLE DB source in SSIS. Each table varies in the amount of colums it holds and niether of the tables have the same field names. I need to transfer all data, from each table, in order, to a flat file destination.
We are using an ADO.NET provider in SSIS to read data from a SQL Server 2000 table that contains DateTime columns to write to a Flat File Destination. When the date values are written to the file they are formatted in TimeStamp to the 10th decimal position; e.g.€œ2006-04-24 12:00:00.123000000€?. Since SQL Server supports values to Timestamp(3), we need to truncate the last seven zeros to put the data in this format €œ2006-04-24 12:00:00.123€? to keep the file as small as possible.
Since we have several hundred DateTime columns in scope for our requirements we are looking for the least logic/effort to accomplish this task. We can do this via Data Conversion and Derived Column transformations to cast the dates and strings but it is very labor intensive. It would be something like singing 99 bottles of beer on the wall eight times in a row with each verse taking 3 minutes each. Yikes.
We have tried casting the DateTime columns to varchar in the SELECT statement but receive this format €œApr 24 2006 12:22PM€?.
Is there a configuration we've missed that forces timestamp(10) with non significant digits?
Hello all, I was trying to run a test to write a ebcdic file out with a comp - 3 number (testing this for other people) and have run into a problem writing the string out to the flat file destination. I have the following script component:
Code Block
' Microsoft SQL Server Integration Services user script component ' This is your new script component in Microsoft Visual Basic .NET ' ScriptMain is the entrypoint class for script components Imports System Imports System.Data Imports System.Math Imports Microsoft.SqlServer.Dts.Pipeline.Wrapper Imports Microsoft.SqlServer.Dts.Runtime.Wrapper Public Class ScriptMain Inherits UserComponent Public Overrides Sub CreateNewOutputRows() ' ' Add rows by calling AddRow method on member variable called "Buffer" ' E.g., MyOutputBuffer.AddRow() if your output was named "My Output" ' Output0Buffer.AddRow() Dim myByteArray() As Byte = {&H12, &H34, &H56, &H7F} Output0Buffer.myByteStream = myByteArray Output0Buffer.myString = "ABCD" Output0Buffer.myString2 = "B123" myByteArray = Nothing End Sub End Class
I have added myByteStream as a DT_BYTES length 4, myString as (DT_STR, 4, 37) and myString2 as (DT_STR, 4, 37) to the output 0 buffer.
I then add a flat file destination with code set 37 (ebcdic us / canda) with the corresponding columns using fixed width.
When i place a dataviewer on the line between the two the output looks as I expect ("0x12 0x34 0x56 0x7F", "ABCD", "B123"). However, when it gets to the flat file destination it errors out with the following:
Code Block [Flat File Destination [54]] Error: Data conversion failed. The data conversion for column "myByteStream" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.".
If i increase the size of the byte stream (say, to 50) the error goes away but I am left with the string "1234567F" instead of the appropriate hex values. Any clues on how to go about this? I obviously don't care if it gets transferred to "readable" text as this is supposed to be a binary stream, thus the no match in target page seems superfulous but is probably what is causing the problems.
NOTE: this is relating to the following thread (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2300539&SiteID=1) in that I am trying to determine why these people are not seeing the "UseBinaryFormat" when importing an EBCDIC file (i see this fine when i use an ftp'd file, but it auto converts to ascii) with comp-3 values. I also see the "UseBinaryFormat" when I am importing a regular EBCDIC file which I create that has no import errors with zoned decimals.
Just attempting to import a simple tab delimited text file into my SQL Server 2005 database using the SQL Server Import and Export wizard. Column names are specified within the first line of the file. The Header Rows to Skip field value is listed as 0, but the wizard indicates that "The field, Header rows to skip, does not contain a valid numeric value".
Why isn't zero (0) a valid numeric value? I don't want to skip any rows. PLUS, I get the same error when trying to export to a text file although the header rows to skip field does not exist. I can increase the number to 1 or more, but the wizard will skip part of my data .. unacceptable.
What am I missing here? I installed SP1 of SQL server 2005, but that did not help.
Hi-I have a sql database (2005) that I need to extract a report from that looks somehintg like SELECT * From Empl_Hours WHERE some_flag <> 'true' .The thing works fine, but the problem is this: I need to insert a record in the 1st row that looks like "Static_text"+row_count() +"more_static_text"where row_count is the actual # of rows that were retrieved. Thanks in advance for any help.DAn
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.
I have a file with a header row which contains the date of the file and under that all the columns without a header.
In SSIS package I skip row and manually name the different columns.
However, I want to use the column in the header row to store the date value in an SSIS variable and use that variable to write it to our staging table. How can I do this when I skip the header row?
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
