Migration From Flat File To SQL Server 7
May 30, 2001
I inherited a flat file system of 100 "tables" with no PK/FK constraints, nor relationships in the RDBMS. The "constraints" are in the application (Bad Stuff I know). It's pretty obvious that they haven't worked.
The files are like this:
File A File B
Last_Name Task
First_Name Date_of_Task
When I run a query I get the following results:
Last Name First Name Task Date
Same Last Name Same First Name Different Task Date
Same Last Name Same First Name Different Task Date, etc.
I want to get rid of the redundant names. I have created a new database with the PK/FK restraints in place. However, I'm not sure how to migrate the old data into the new database. I want to make the Task column a date rather than a task itself. The task will be labeled in the column heading.
I'd like the outcome from a query to be:
lastname First Name Task 1 Task 2 Task3,....
I'm new to SQL and it seems like I need to run some sort of Sub Query, but I haven't been able to hit on the correct command/syntax. Thanks for your help.

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,
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?
Any inputs will be appreciated.

Hi all,
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?
thanx

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.
Code Snippet
Record Length 400
Positions Length FieldName
Record Type 01
1,2 L=2 Record Type (Always "01")
3,12 L=10 Site Name
13,19 L=7 Account Number
20,29 L=10 Sub Account
30,35 L=6 Balance
36,37 L=1 Active
37,41 L=5 Filler
Record Type 02
1,2 L=2 Record Type (Always "02")
3,4 L=2 State
5,30 L=26 Address
31,41 L=11 Filler
Record Type 03
1,2 L=2 Record Type (Always "03")
3,6 L=4 Coder
7,20 L=14 Locator ID
21,22 L=2 Age
23,41 L=19 Filler
Record Type 04
1,2 L=2 Record Type (Always "04")
3,9 L=7 Process
10,19 L=10 Client
20,26 L=6 DOB
26,41 L=16 Filler
Record Type 05
1,2 L=2 Record Type (Always "05")
3,16 L=14 Guarantor
17,22 L=6 Guar Account
23,23 L=1 Active Guar
**There can be multiple 05 records, one for each Guarantor on the account**
and the single line flat file...
Code Snippet
01Site1 12345 0000098765 Y 02NY1155 12th Street 03ELL 0522071678 29 04TestingSmith,Paul071678 05Smith, Jane 445978N 05Smith, Julie 445989N 05Smith, Jenny 445915N 01Site2 12346 0000098766 N 02MN615 Woodland Ct 04InfoJones,Chris 012001 01Site3 12347 0000098767 Y 02IN89 Jade Street 03OWB 6429051282 25 04Screen New,Katie 879500
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!

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 want to transfer this file to a sql server database table.
My problem is how to send the above string to a table by formating like removing commas.
Can I do that using DTS. I need the answer very quickly.
Any help would be appreciated.
Or there is any better way to transfer the content to the table.

Hi.
I want to import a flat file to my sql server database. My sql server and web server are on different machines. I used a bulk insert to import the data using a Format.. But now since the sql server and the web server are on different machine it doesnt load the data to the sql server..
i have tried giving http://Ipaddress/Path and that didnt work.. tried mapping the network drive to the webserver and then specified the location and that didnt work too..
I found this connection string on the internet
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c: xtFilesFolder;Extended Properties="text;HDR=Yes;FMT=Fixed";
but i am not sure how to give a ~ delimited and specify a format file..
any help will be appreciated..

I am trying to import into sql server from a .csv flat file i made in excel. The problem is the Primary Key. It is set to auto increment.
When i leave an empty column i get:
"Directcopyxform conversion error:destination does not allow null"
when i just omit the column entirely, i get a wrong datatype error because it basically tries to copy all the columns 1 shift to the left
How am i supposed to represent and auto PK in .csv file. Thanks

I am new to SQL Server, and migrating part of an Access application toSSE. I am trying to insert a comma delimited file into SSE 2005. I amable to run a BULK INSERT statement on a simple file, specifying thefield (,) and row () terminators. I can also do the same with aformat file.Here is the problem. My csv file has 185 columns, with a mixture ofdatatypes. Sometimes, a text field will contain the field delimiter aspart of the string. In this case (and only in this case) there will bedouble quotes around the string to indicate that the comma is part ofthe field, and not a delimiter.Is there any way to indicate that there is a text delimiter that isonly present some of the time?If not, any suggestions on getting the data into SSE?Many thanks for your input.Cheryl

We are trying to use SSIS Import export wizrd to import the flat files (CSV format) that we have into MS SQL Server 2005 database tables. We have huge number of CSV files. Is there a way by which we can import these flat (CSV) files in to corresponding SQL server tables in a single shot. I would really appreciate this help as it is painful to convert each and every file using the Import Export wizard.
Thank you very much,

After performing a join operation on two tables i get the below resultset
pid, fname, typename, pname, pcost
1, cad, bars, product-1, 100
2, har, witte, product-2, 120
3, nes, bars, product-3, 119
Now i need to create files with the obtained resultset like
Column 'fname' is the folder name and 'typename' should be the file in the particular folder.
For example the first record should be inserted into file name 'bars.txt' in the folder 'cad' and third record should be created in file name 'bars.txt' in the folder 'nes'.

I have a table dbo.Sales that contains all sales records. There is a column in that table called ItemNumber that I'd like to match with ItemNumber in a flat file and update the ItemCost based on the ItemCost column in the flat file.
So while there will be many sales records for each ItemNumber, I need to loop through and update the ItemCost in that sales record based on the corresponding ItemCost in the flat file. Does this make sense? I really need this for court and I can't figure out how to do it. I took a SQL course about 7 years ago but have forgotten everything.
Database Name: BTData
Database Table: dbo.Sales
Database Columns: ItemNumber (match on this), ItemCost (update this)
FlatFile Name: InventoryCosts.txt
FlatFile Columns: ItemNumber, ItemCost
There will be many sales records for each ItemNumber in the database table. I need to update each one with correct cost based on the item number and cost mapping from flat file.

Can we bulk insert only the desired column from a flat file to a table?
I am using SSIS to bulk insert from a file with more than 200 columns. I am trying to find a way I can bulk insert them to multiples table through SSIS.
The one way I can think is pre map the columns from the file to the destination tables. Build numerous Bulk Insert tasks to achieve that. But not sure if SSIS will let me do that.

I'm in the process of importing a series of flat files into SQL Server. I'm using a ~ to separate the columns and the row delimiter is {CR}{LF}. One of the files has a field that contains the CRLF combination in a few places so that field is split over several rows. This is readily visible when I look at the flat file. However, when I'm importing the file, the Import and Export wizard seems to ignore them and import the files as they should with one row per record.
