Multiple Flat File Import To Corresponding SQL Server Tables
Mar 23, 2007
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,
Regards,

So here's the issue
16 flat files all fixed width. Some over 350 columns.
Open flat file 1
extract id and go see if its in table 1, if true update table 1 with first 30 columns
otherwise insert into table 1 first 30 columns.
goto table 2, lookup id, insert/update next 30 columns...etc..etc..for 10 different tables
So I've got my flat file source, I do a derived column to convert the dates, i've got a lookup for table 1, then 2 ole db commands, 1 for update if lookup successful, 1 for insert if lookup fails.
How can I pass the id as a param into the update command so it updates where x = 'x'
also I need a pointer on doing the next lookup, eg table 2, would I do this as some sort of loop?.
If you can help great, but, please don't just reply with "I'd use this object"...then no explanation of how

Probably a stupid and regularly asked question but I can't seem to find an answer, so here goes,
we have 16 .txt files, some with over 350 columns.
That info from each individual file needs importing to multiple sql tables.
need to look at sql table1 does record exist? if not create new then add in data once its been transformed eg datetime from yyyymmdd into datetime values [managed to get this using derived column] for first 20 columns, otherwise do update for the 20 columns...
then look at sql table2 and repeat for next n columns....
So I was wondering is it going to be better to write this as a dtsx package? if so can you point me to an example
or should I just write the code as part of a code behind page that scrapes the info and does a standard update/insert procedure?
Any help would be welcome.
thanks

Hi,
I want to combine a series of outputs from tsql queries into a single flat file destination using SSIS.
Does anyone have any inkling into how I would do this.
I know that I can configure a flat file connection manager to accept the output from the first oledb source, but am having difficulty with subsequent queries.
e.g. output
personID, personForename, personSurname,
1, pf, langan
***Roles
roleID, roleName
1, developer
2, architect
3, business analyst
4, project manager
5, general manager
6, ceo
***joinPersonRoles
personID,roleID
1,1
1,2
1,3
1,4
1,5
1,6

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.

I have a text file which contains the data that has to be inserted into multiple tables.The columnames of table 1 form the H1 follwed by Details D1,D1,D1...
The column names of table two form the H2 followed by details D2,D2,D2 so on and similarly for Table 3.
Am using a link server to the file directory and schema.ini which defines the column names fofr the text file
Is there any way of defining column names for more than one table through the schema.ini? or is there any other way through I can parse the text file contents to multiple tables?
Sample text file:
H1,JobDate,JobNumber,FileName,
D1,13/02/2008,asdf123,text1.txt
D1,13/02/2008,asdf123,text2.txt
D1,13/02/2008,asdf123,text3.txt
H2,PagesUsed,PagesPrinted,Pages emailed
D2,10,10,9
D2,1000,100,99
D2,50,22,93
Schema.Ini - defined for the first table
[LogConfig.txt]
Format=CSVDelimited
CharacterSet=ANSI
ColNameHeaders=true
Col1=JobDateText Width 20
Col2=JobNumberText Width 20
Col3=FileName Text Width 100
Hoe do i define the column names for the second table. All these contents are in a single text file and need to be parsed only thru sql.
Any help/suggestions are welcome..
Thanks a lot for taking time to read this.

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 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

I am new to SSIS....
I have a very simple package that has a flat file source object and an ole db destination object in the data flow. All works fine.
If I change a row in the flat file to make it fail how do I make the program continue and go to the next row?
The ole db destination does not have a Error Output properties like the flat file source does.Thanks

I have a couple of hundred flat files to import into database tables using SSIS.
The files can be divided into groups by the format they use. I understand that I could import each group of files that have a common format at the same time using a Foreach Loop Container.
However, the example for the Foreach Loop Container has multiple files all being imported into the same database table. In my case, each file needs to be imported into a different database table.
Is it possible to import each set of files with the same format into different tables in a simple loop? I can't see a way to make a Data Flow Destination item accept its table name dynamically, which seems to prevent me doing this.
I suppose I could make a different Data Flow Destination item for each file, in the Data Flow. Would that be a reasonable solution, or is there a simpler solution, or should I just resign myself to making a separate Data Flow for every single file?

I used the data export wizard to export a single table to a single flat file (multiple wasn't allowed). I saved the package as a *.dtsx file which I'm attempting to edit to add the additional tables.
Creating additional sources is fairly easy copy of the first source and change to the table name.
I've tried copying the destination connection and changing to a new text file, but can't get past having to add each column manually to the new destination.
How can I duplicate the mapping that must be taking place in the wizard in the *.dtsx editing environment?
This seems like a simple / common task, but I've been unable to find a solution.
Thanks, Richard

I need to consume a live data feed from a golf tournament. And by consume, I really mean insert (merge) into our own SQL Server database on a regular intervals as a tournament progresses.This site didn't let me upload an XML file, but you can see a sample of the data feed here: URL....
I need to insert this data into 2 tables, Player_Holes and Player_Shots. But while doing the insert, I need to lookup several things such as our player ID match to theirs on an external_id against the players table. The shot types translation, and some other logic about the process overall.
The columns in my player_holes tables are: id, player_id, hole_id, round, shots (this is a total # of strokes) and date_created/date_modified.Shots table is similar: id, player_id, hole_id, round, shot_number, shot_type_id, club, distance, date_created/date_modified.
The only way I know how to do it, is inefficient. I would parse the XML in ColdFusion (please no comments on ColdFusion, that's what we use for webdev), and then loop over it and do inserts for each player, each hole for each round, and the shots would probably be separate for each hole.
It would be so much better and more efficient if I could do it in SQL directly. I've done some research and SQL Server Data Tools looks promising. I've never used it, so would have to learn, but also I'm not sure if that'd work in this application when we want to run is as a scheduled task every few minutes.

We just upgraded from SQL Server 2000 to 2005. In the past, when I ran the import/export wizard to copy multiple tables from one database to another with SQL Server 2000, I had no problem. Now when I used the import/export wizard to copy multiple tables with SQL Server 2005, I kept getting an error. For example, when copied three tables, the first table might be copied fine and I got an error with the second table and the whole thing stop. Sometimes I could copy two tables. However, when I ran the import/export wizard to copy each table one at a time, it worked.
The error that I got was "Cannot insert duplicate key in object..." I selected the options to "Delete rows in existing destination tables", and "Enable identity insert". What am I doing wrong?

I have a report that's created each day as a flat textfile.Because I came from the Access world, I created a macro that importsit with a schema that gives meaningful names to the various columns,and then uses a query to massage some of the data for me (deletes thefirst blank row and does a couple of calculations)Then I use DTS to import the Access query as a table.the textfile has a column called "File_num", and among several others,a column called "Serial_num". (the file numbers represent shipments,and sometimes there are more than one serial number in the shipment,etc., so there is a separate line for every serial number)Naturally, I would like to split this info into two tables..one thatdoes not contain the serial numbers and has a primary key on the"File_num" column, and another table that would contain just the"File_num" and "Serial_num" columns. That way I could relate themlater...but most importantly, it will give me a table where I can usethe "File_num" as my primary key.What would be the best way to import these two tables from one sourcetextfile? The other thing that gives me problems is that the textfile has no column names, and the first row is always blank.I'm very new to SQL and DTS and would appreciate any direction.Thanks,Larry- - - - - - - - - - - - - - - - - -"Forget it, Jake.

Hello, I'm trying to import data from a flat file into a table that has smalldatetime data types. I tried creating triggers on the smalldatetime data types that converts the data from a string to a datetime value but the import is still unsuccessful. What should I do?
Col002 looks like this in my flat file 'ex: 20000112'
DTSDestination("entry_dt") = DTSSource("Col002")
I get an error when trying to put the value of col002 into entry_dt.
Thanks.

Hi,
From the filemaker database, I am exporting data to the Flat file separated by tabs. From this Flat file I need to import into Sqlserver table. The Flat file has the 23 columns and 4000 rows.
To insert into Sqlserver table I am creating the Flatfile connection.
In the dataflow tasks, I am creating the Flatfile source, OLEDB destination and mapping the columns. And to run the package I am doing the Debug->start with out debugging.
In my flat file I have columns like SSN, Email. So in Sqlserver table I am defining the columns as the Nvarchar(200).
If I insert the 6 rows data from flat file to Sqlserver, this works fine.
If I tried to insert the 23 rows data, by clicking on Debug->Start debugging -> no data inserted into Sqlserver table. the arrow between flatfile source, OLEDB destination is showing the 450 rows. How can I view the errors?
When I mouse over on the OLEDB destination, it is showing "truncation occurs on the column (20th column) more than 512 characters.."
Initially the Output parameter length is 50 and datatype is Unicode char, I increased it to 512.
What is the problem here? If there are more columns I am not able to insert data.
How to view the errors?
Thanks

Hi!
I just used the SSIS Import and Export Wizard to copy 50+ tables from SS05 to SS2K.
I found that the wizard created a package that I could not figure out how to edit, e.g., to change whether or not it had to CREATE a table, or just use an existing one. (I created some problems by manually editing the receiving table names to be ones that already existed -- but the original names it had did not exist, so it knew it had to create them. What I should have done, and eventually ended up doing, was scroll through my list of tables in the "receiving" box; I just figured editing the name would be faster, not realizing what problems I would create for myself.)
Anyhow, now that I see the complex package that the wizard creates, with a LOOP over the 50+ tables, I would like to know how/where in the package it is storing the information about the tables to copy.
Basically the wizard creates the following Control Flow tab entries (in processing sequence order):
an Execute SQL Task: NonTransactableSql
an Execute SQL Task: START TRANSACTION
a Sequence Container: Transaction Scoping Sequence, which contains
an Execute SQL Task: AllowedToFailPrologueSql
an Execute SQL Task: PrologueSql
a Foreach Loop Container, which contains
a Transfer Task with an icon I did not notice in the Toolbox
an Execute Package Task: Execute Inner Package
an Execute SQL Task: EpilogueSql
an "on success" arrow to
an Execute SQL Task: COMMIT TRANSACTION
an Execute SQL Task: PostTransaction Sql
an "on failure" arrow to
an Execute SQL Task: ROLLBACK TRANSACTION
an Execute SQL Task: CompensatingSql
Where, and how, can I look within this package to see the details about the tables I am transferring? I see that one of the Connection Managers is "TableSchema.XML" -- but it points to a temporary file on my hard drive, that I presume is populated by the package. Where does it get its information?
This is certainly much more complex than the package I would have written, based on my limited knowledge of SSIS. I would have been inclined to create 50+ Data Flow tasks, one for each table.
So now I'm trying to understand why the Wizard created this more-complex package.
Any help will be appreciated, including references to non-Microsoft books/websites/etc.
Thanks in advance.

I am trying to import a flat file into SQL Server 2005 using SSIS. I have never used it before and I am getting confused by the error I am receiving.
I have a link to a flat file, that gets sent through a Derived Column flow where dates in YYYYMMDD are changed to MM/DD/YYYY format. Then the string MM/DD/YYYY is converted to a date in a Data Conversion flow. And finally the data is put into a SQL Server table (currently with no rows).
The problem I am having is with a text field with the email address in it. The error I am getting is:
[Import Allstate Auto Club [1]] Error: Data conversion failed. The data conversion for column "email_source" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.".
The problem is I can't see where in the flow the problem is. The field length is 20 wherever I look and the codepage is 1252 wherever I look. Does anyone have an insight? Keep in mind, I have never used SSIS before and I consider myself an amateur with SQL Server. It could easily be a data type conflict or something easy. Any help will be appreciated.

I have a fixed width flat file I'm trying to insert into an SQL 2005 table using SSIS -- it's a recurring task. One of the columns in the flat file has to go to a column of type Numeric. No matter what I try : a data conversion, defining the field as DT_NUMERIC in the connection,... I always get "The conversion returned status value 2 and status text :The value could not be converted because of a potential loss of data". It is driving me bonkers, up to the point that I find myself wishing for the 'good old' DTS days of SQL 2000. And I dread to think what will happen when I try to port some serious, much more complex DTS packages on my SQL 2000 to SQL 2005.
The data in question represents longitudes and latitudes so quite often there is a leading white space in the data : ex. : " 95.15". Surely that cannot be the cause ?
I've spent hours doing the RTFM-thing and searching the newsgroups, fora...you name it. Apart from ending up running in circles in the MS documentation, the only thing I've really learned so far is that I'm aparently not the only one driven to dispair by the new SSIS thing.
I can think of a number of ways to hack my way around this thing, but that's not the kind of 'progress' I had in mind when I started the move to SQL 2005.
Intelligent suggestions would be most welcome.

Boy, do I need HELP! Have a simple csv file that I need to import. Worked fine in sql2000; I put it into dts to execute on a monthly basis. Makes connection, db connection, table creation fine, but stops at validation of flat file?
Basically, I want to go out and get a flat file, drop the existing table, and create the table, and import the information from the flat file. Not a complicated table of about 30,000 records.

Hi,
I'm going to be getting several flat files that need to be imported into one of two tables. Although the text files will have different file names, they will have either "Header" or "Detail" in the file name, so I can tell which table they need to be imported into.
The problem is I don't know enough about SQL Server 2005 to set up an automated import of these files into the database. Does anyone have any suggestions on how to do this, or have any experience in setting this up? Are there any inexpensive programs to load data realtime or on a schedule? (I work for a young company with a very tight budget).
I had an idea of creating a windows vb or batch program to create the import commands for each of the flat files, but I can't find the line command to build the import command.
I'm just at a loss and need a solution soon...
Thanks,
Laura

I have a flat file that uses tabs as the column delimiters and cr-lf as row delimiters. The first portion of the file consists of only two columns for approximately 10 rows and then the file changes to 4 columns for the balance of the file, about 21 rows. The column names are in the first column and the data of interest is in the second column for the first 10 rows and then in the third column for the last 21 rows. Is it possible to set up something like this for parsing in SSIS? I've tried using two columns in the data flow task but then I get columns 1 and 2 through the whole file. If I tell it there are 4 columns in the file, it appends rows to each other so that there is a total of 4 columns in the first 10 rows. This reduces the row count to less than 10 and the data in these rows isn't in the proper place. Is there a way to handle this file in SSIS?
TIA

I€™m looking for advice for the following scenario:
Import Source: Flat File €“ 2 columns (student#, lunch_bal)
Destination: SQL Table:
Trnpayuniq (PK)
Atype (all values = €˜S€™)
Auniq ( from flat file €“ student#)
Trnamt (from flat file €“ lunch_bal)
Trnpayc (all values = 1)
I€™ll truncate the destination table before each import.
Is the best way to create a temp table; get it populated
then update the destination table? Or
would the use of Merger (Merge Join) be the better approach.
Thanks for any direction.

I have a fixed width flat file that I'm trying to import, and I'm just about there. The last column that I'm struggling with, is a decimal amount. The data in the column looks like this 00000000500 and I need to dump it into a column as 5.000 In otherwords, the data in the file does not have any decimals, and I'm putting it into a sql server column that has the datatype numeric(11,4) I've set the InputColumnWidth to 11, the DataPrecision to 11 and the datascale to 2, and the value is still being imported as 500.000 Is there any way to achieve this other than using a script component to calculate the value? Thanks!

Hi,
I wanted to know if there was a way to import data from a flat file without specifiying the delimiters. I want to import each line in one row so that i can use the substring function to break of the data as an when i want and not as per the delimited format file or the wizard.
i.e if row one had "abc"|"1453"|"Jack"|"Smith"| etc.... rather than importing these as different columns and rows. I want this all in one row, one column.
Is it Possible?

Hi,
I have searched but not found quite the best way to look at this so far..
I have an application that outputs data to several text files (up to 30). These have commonality by an object name, but then contain completely different column data.
In DTS I had each of the source text file connections going to one OLE DB connection and then individual transform data tasks pointing to the one OLE DB connection.
Looking at SSIS, it would appear that I would need to have one source and one destination for each of these and therefore 30 parallel data flows?
Just wondering if there is a neater way of doing this??
It is a regular data import that happens a few times a day - the text files are named the same as the SQL tables - ie app_userdata.txt goes to app_userdata table.
Hope that explains ok and thanks in advance.

Hi all,
I'm totally new to SQL Server 2k5 and need to do something rather basic: import some CSV files into tables. I'm getting translation errors and would like to know what's the best way to cast the strings before inserts.
I'm doing the import in BI Development Studio.
Current situation:
Created connection managers to csv files
created SQL server destinations pointing to the tables
connected them directly with a dataflow path
Ran the packadge: one import went just fine, the other one complains about conversion errors like "Conversion DT_STR and DT_I4 not supported"
Both tables have the same kind of fields (varchar, float, datetime, int)
I looked at converting the data using a transformation but am somewhat confused of which one to use.
What's the best way to transform the data before insert: derived column, import column or data conversion? Or something else I overlooked?
TIA
Peter
