Read Of Flat File, Some Data On 1st Row Should Be Stored In Variables
Apr 7, 2008
I'm reading a Flat File.
The 1ste record containts special Info that is needed for first preparing the database on a buld insert of the remaining lines.
How could i realize this, just read 1 line, store some of that data into variables, execute some proc's and then read the rest of the file ?
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?
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
Hi, I want to read only the first row in flatfile. I do not see this option on "Flatfile connection manager editor" setting wizard. Any work around for this?
I have a few flat files that I need to read a date from. The date will always be on Line No 4 and will be in YYYYMMDD string format in chars 2-9 of line 4
Here's what I have so far to convert the string YYYYMMDD into date format... I don't know enough VB to be able to just hit Line 4... I am sure it's simple so could someone pelase put me out of my googling misery

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."
What is the easiest way to accomplish this task with SSIS?
Basically I have a stored procedure that unions multiple queries between databases. I need to be able to export this to a text file on a daily basis and add a total records: row to the end of the text file.
I have a filetable that contains a binary file. I need to do a selective read of the file stored in the file table. I can write a C# CLR function that will open the file, read n bytes the from a starting byte. Or I can write a SQL statement that reads the stream in the filetable into a VARBINARY variable using SUBSTRING beginning at the starting byte (offset from 1) for the same n bytes.
Both give me the same result. However, the SQL statement takes considerably longer to read. I know there is overhead in reading through SQL (interpreted language), but the difference in performance is substantial, and I can only attribute this performance degradation if SQL first tries to "load" the entire stream before it identifies the portion of the stream that it needs to read beginning at the starting byte offset.
I wonder if this is the case or if there is another option to read a stream from a filetable directly through SQL queries that is more efficient.
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.
In a foreachloop, I am inserting records into a flat file which is working fine. But the thing is that as the file grows, it takes longer for it to locate the EOF(End of File) of the flat file so as to insert the records.
I have around 70-100 lines written to the file at each loop and there are more than 20k records to be looped. wihich means that at the end I should be having 1400k - 20000k line in the text file.
One solution would be to insert the records at the start of the file itself so that it does not has to lookup the EOF each time before writting.
Another would be to generate separate files and then merge it.
Any idea how can this can be done?
Beside this I have to zip the file and then SFTP to a given address.
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 running my package in sql server 2012, in which i am giving network path for flat file destination. And its working fine. But if i give m local path, its giving me error " cannot open data file" ...
How do I insert data from a flat file or .csv file into an existing SQL database???
Here what I've come up with thus far and I but it doesn't work. Can someone please help? Let me know if there is a better way to do this... Idealy I'd like to write straight to the sql database and skip the datset all together...

I tried to find some information about this, but surprisingly can't seem to find anything. Seems like it would be a very common scenario.
I need to send the output of a stored procedure to a flat file. First, I created an Execute SQL Task that calls the stored procedure. I selected "full result set."
My first question is, how do I capture the individual column values? For example, under "Result Set", should I create an Object variable, or should I use individual column variables? I've tried both ways, but can't seem to get to the next item, below...
Now, how do I map the variables to the flat file? If I use a data flow task, the flat file has "no available inputs". If I add an OLE DB Source before the flat file destination, there's no place to capture the result set.
I m using SSIS and i am transfering the data from Flat File Source to the OLE DB destination File. The source file contain some corrupt data which i am transfering to the other Flat file destination file.
Debugging is succesful but i am not getting any error output in the Flat file destination file.
i had done exactly which is written in the msdn tutorial of SSIS.
Plz tell me why i am not getting the error output in the destination flat file?
I have to value [CreateDate] in the data pump of my Flat File Source into my OLE DB Destination SQL Server Table. With a Variable within the SSIS Package or with a Derived Column task within the Data Flow between the Flat File Source and OLE DB Destination?
I'm moving data between identical tables and have to use a flat file as an intermediary. I thought: "No problem, SSIS can do a quick export to a file, then move the file to another server, then use SSIS to import the data to the new server."
Seems simple, right?
I'm hitting all sorts of surprising data conversion errors. I used the export wizard to create the export package. This works fine. However using the same flat file definition, the import package fails -- even when I have no destination. That is I have just one data flow task that contains only one control: the Flat File source. When I run the package the flat file definition fails with data type conversion and truncation errors. One of the obvious errors is for boolean types. The SQL field is a bit, SSIS defined the column as DT_BOOL, the output of the data are literal text values "TRUE" and "FALSE". So SSIS converts a sql datatype of bit to "TRUE" and "FALSE" on export, but can't make the reverse conversion on import?
Does anyone else find this surprising? I would expect that what SSIS exports, it can import given all the same table and flat file definitions. Is SSIS the wrong tool to do such simple bulk copies? I'd like to avoid using BCP because this process will need to run automatically within SQL Agent so we can leverage all the error tracking and system monitoring.
I was wondering how I could pass on the following parameters from an ini file to a stored procedure within a DTS package. The parameters in the ini file look like:
[DatabaseCleaner] ! -- TableToBeCleaned_N=<table name>,<months to hold on db>,<months to hold on hd> ! -- <N> must be a successive number starting from 1 ... TableToBeCleaned_1=Transactions,24,24 TableToBeCleaned_2=Payments,24,24 TableToBeCleaned_3=PresenceTickets,24,24
As I do not know how many tables that will be declared in the ini file I have to loop through until the last parameters and pass it over to the SP.
First, a couple of important bits of information. Until last week, I had never touched SISS, and therefore, I know very little about it. I just never had the need to use it...until now. I was able to convert my first 3 flat files to SQL2005 tables by right clicking on "SISS Package" and choosing "SISS Import and Export Wizard". That is the extent of my knowledge! So please, please, please be patient with me and be as descriptive as possible.
I thought I could attach some sample files to this post, but it doesn't look like I can. I'll just paste the information below in two separate code boxes. The first code box is the flat file specifications and the second one is a sample single line flat file similar to what I'm dealing with (the real flat file is over 2 gigs).
My questions are below the sample files.

As you can see, each entry could have any number of records and multiples of some of the record types, with one exception, every entry must have a "01" record and can only have one "01" record. Oh, and each record has a length of 400.
I need to get this information into a SQL 2005 database so I can create a front end for accessing the data. Originally, I wanted one line for each account and have null values listed for entries that don't have a specific record. Now that I've looked at the data again, that doesn't look like a good idea. I think a better way to do it would be to create 5 different tables, one for each record type. However, records 2 through 5 don't have anything I can make a primary key. So here are my questions...
Is it possible to make 5 tables from this one file, one table for each of the record types?
If so, can I copy the Account number in record 01, position 13-19 in each of the subsequent record types (that way I could link the tables as needed)?
Can this be done using the SISS Import and Export Wizard to create the package? If not, I'm going to need some very basic step by step instructions on how to create the package.
Is SISS the best way to do this conversion or is there another program that would be better to use? I know this is a huge question and I appreciate the help of anyone who boldly decides to help me! Thank you in advance and I welcome anyone's suggestions!
1. I am attempting to export data from a SQL DB (single table using a query) to a "flat file". 2. I would then like to take this "flat file" and import the data into a different SQL DB (same schema structure as first DB).
How do I put data into a text or excel file before I attempt a deleteion from a large table. I know how to select the necessary data, but i'm not sure about the t-sql required to put it into a file?
I was wondering if there was a way for me to append data to a flat file. The reason why i ask this is because i need to create a header for the report that i am exporting.
The way i imagined this working would to be create a dts that would export the header information to a flat file and the create another dts to export the report data and appensd it to the same file that the header dts created. This might not be the correct approach so i was hoping i could get some guidance of how i can accomplish this.
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:
I'm using SSIS package to export some data to a comma delimited CSV file. The problem is that some of the fields have commas in them. Is there a way to deal with this other to changing the delimiter?
I am looking to import data into SQL Server 2005 using SSIS. I want to take data that is contained in a flat file and place it into the various appropriate tables in my system. The flat file contains nested data. For example...
Bob,Smith,555-5555,123~3.33|245~1.99,Active
So I want to build a package that brings in the records as follows
Client Table: First Name, Last Name, Phone, and Status (Bob, Smith, 555-5555, Active)
Order Table: OrderID, Amount (ID 123 @ $3.33 and another row ID 245 @ $1.99). If possible I would also like to tie the orders to the client record that was inserted.
My first question is if SSIS supports nested fields as in my example. Can it break a file by commas, then within a field by other delimiters? If so how do I do this, and if not what is the recommend way to accomplish this sort of task.
My second quesiton is if it can do that, can it tie the Client and Order data on the fly?
