SSIS Import Text File To SQL Server With Nulls?
Jan 23, 2007
I have a text file I am trying to import into SQL Server using OLEDB connection.
It's a fixed field text file, ragged right format. One of my columns maps to a numeric column in the DB. In some spots in the file, it is blank, in others there is actual numeric data.
I can't get it to import. If I set the text file column to numeric, I get an error "That value could not be converted because of a potential loss of data." If I set the text file column to string, I get a similar error from the OLE DB provider, "Invalid character value for cast specification"
I have tried telling it to retain nulls in the data flow and the other way as well. Can someone tell me what I am doing wrong?

what is the best way to import fixed length text file to sql server using SSIS?
I was trying to using text file source and ole db destination..but since the text file has no columns and have different length per column and per line( it show only one column becasue it all concatnated), I can not map it to destination column..
How can I import it?
Here is the example of text file ( fixed with row delimeter)that i need to import to different columns...
010000000000000000001164.00023 YV

Hi,
I would like to know how to import in the custom delimited text file by using SSIS.
For example, instead by using tab or comma delimited, I use this character : '¶'
The reason is the delimited format that SSIS provided is too common such as colon, semi colon, tab, comma and pipeline.
I have the data that the user also key in the pipeline there. So I am thinking to separate the field by using this special character, but cannot see if there is anyway to import in by using SSIS.
Please help to share the solution on this :
A¶B¶C
1¶2¶3
thanks
best regards,
Tanipar

More SSIS woes. DTS was so much easier.
I have a flat file. It's fixed-with with CRLF record delimiters (a.k.a. Ragged Right format).
Some fields are null, and represented by the text NULL.
I'm trying to import the file into SQL via an OLE DB connection. The target table is a SQL 2000 data table. Two of the fields in the target database are of type smallint.
When I run PREVIEW on the data source (Flat File), everything looks good & correct. I added the convert columns task to convert my strings to smallint. This is where things go haywire.
After linking everything up, the conversion gives me a "Cannot convert because of a possible loss of data." All of my numbers are < 50, so I know this isn't the case. Another SSIS bogus error
My first instinct is the SSIS doesn't understand that NULL means null. I edited the file and replaced all instances of NULL with 4 emtpy string chars. Still no good. It seems to be having a hard time parsing the file now.
I dropped the convert task and tried editing the data source, and set the two smallint fields to smallint instead of string (SSIS formats). I get the same conversion error.
Changing the NULL values to 0 fixed the problem, but they're not 0. They're null.
Short of creating another script that converts all zeros to NULL using the aforementioned hack, I'm out of ideas.
I'm I missing something or is SSIS just incapable of handling nulls in fixed-width flat file formats?
TIA

Hi there,When importing a text file using SQL Server, how do I specify the pathto a file on the same remote server that SQL Server is running on? Itried //c:/filename but that doesn't seem to work.Also, once the import is working, how do I write a DTS package tofirst delete all rows in a table, then repopulate with the text file,or is it easier to drop the table, re-create it and then repopulate?The table will contain approximately 30,000 records.thanks for your help,K

We are using the bcp utility (via APIs) to export data from a SQL tablein a fixed format text file. BCP is inserting spaces for a field ifthe field contains a NULL. This is fine with us except at the end ofthe line, there are no spaces for that field just the end-of-rowterminator prematurely, so it looks like that field is not present andmesses up another piece of software we pump the text file into downstream.Example -- The last row illustrates the problem.123-49-890 Mary Smith Raleigh NC
999-88-123 Henry Ax Boston MA
456-99-123 Sue Kite WA
789-88-126 Andy Yates Philadelphia
We have thought about using a SQL query to convert the NULL dataexplicitly to spaces, but were wondering is there a switch or somethingin our format file to get around this.Thanks.

Hi all,
I got a unicode file source with this fields:
-DT_WSTR (100) originally is DT_STR(100)
-DT_WSTR (100) originally is DT_STR(100)
-DT_NTEXT
-DT_WSTR (20) originally is DT_DBTIMESTAMP
-DT_WSTR (5) originally is DT_BOOLEAN
I export a Query result to a File (see above) ...as unicode TXT destination.
OK, now I must to re-import into another DB and here is my difficult...'cause the DT_NTEXT is HTML code and I got always this error:
[Flat File Source [1050]] Error: The column delimiter for column "scheda" was not found.
Scheda field is the DT_NTEXT.
Into connection manager area I modify the advanced tab for the set-up of my fields setting all to:
Unicode string [DT_WSTR] with a variable of the len, but Try also to define everyone to the rigth type of the SQL destination like:
- DT_STR(100)
- DT_STR(100)
- DT_DTNTEXT
- DT_DBTIMESTAMP
- DT_BOOLEAN
In every type of action I see no message alert and all seem to be good, but when I try to execute got always same error...
So hope someone can help me...

I have an .xlsx file where I need to import the data into a table. If there is not a way to do this, is there a way to import either a tab del file or different type of .csv file into the database?
Do not want to use the SSIS or import feature from SQL2008 as I tried to save the steps and running it wont work either.

Hello,I am receiving a text file that is produced from a mainframe that isout of my control. I am attempting to find a (hopefully clean) way toimport it into a SQL Server database in an automated fashion. I amnot really concerned about how many tables it requires or what theschema looks like as long as the data remains related and ends up inits respective fields (I will probably use scratch tables for this).The data is given to me in a format that is meant to be printed outand read by human eyes (in a text file). The format looks somethinglike this:Begin File:-------------------------------------------------------------------------------1234 1234 1234 1234 XYZ Company 01/01/2003.......More stuff related to XYZ company for a couple of lines ..............(this stuff can easily be parsed by position).......MCARD VISA AMEX DISC-------------------------------------------------------------------------------TOTAL 11111.11 4444.44 5555.55 30.01TRANS FEE .20 .20 .15 .15TRANS AMOUNT 2222.22 888.89 833.33 4.50DISC .0165 .0165 .0365 .0355-------------------------------------------------------------------------------ANOTHER HEADER............More stuff related to XYZ Company................End File:Well, this isn't the exact format, but just an example. The point isthat all of the data in each column is related and should end up inthe same record which is related to the parent record of XYZ Company(or all in a single record in a single table if that is the closest Ican get).Also, the rows are not always present. For example, if TRANS FEEdoesn't apply to anything in the row, then the entire row willcollapse and TRANS AMOUNT would be the next line after TOTAL.I was looking at the bcp utility and dts, but dts doesn't seem to havethe performance capabilities (or reliability for that matter) I amlooking for. Bcp seems like it might work if there is some advancedformatting commands that I can't find in the documentation - Anyone?The best I can come up with is to use a high level language such as C#or VB.NET to parse the text file into another text file that is commadelimited, and then use the bcp utility (or bulk insert) to import itinto SQL Server where I can then use TSQL to manipulate it how I want.I am trying to eliminate the high level language parse and just gostraight from file to database. Does anybody know an easier route?TIA

I'm trying to create an import package using BIDS. I'm using SQL Server 2008. The data is saved as a .csv file so that I can use the flat file option for data source. The issue I am having is that when I preview the flat file after selecting it as the datasource, some of the data that have the numeric file format are showing up as non numeric, for instance the value -1,809,575,682,700 is being viewed as ""1 and the package is giving a conversion error.

SQLServer 7.0
Hi,
I have a small project on that involves importing a series of csv files held within an ftp directory into our Datawarehouse. Every day a series of csv files will be added to the directory. These will be named something like:
Audit1.csv,Audit2.csv etc.
I would like to automate this process as this can involve up to 400 files at a time. The proecedure would need to identify a valid file, import it into the database, delete the file and then move onto the next one.
Does anyone know of a way to achieve this? I was thinking along the lines of using a cursor and bcp but I'm not sure how to identify these files to the database i.e. how do i make it step through the directory and process the files?
Any help would be greatly appreciated.
Thanks
Rob

In a DTS package I have a text file import object, a data pump, and a SQL object. The text file import object has been set up to splice a 500 character wide file into 20 columns. The data pump task does a copy column for all the columns into the appropriate table. What I need to do is have a way of changing the file name I specify in the text import object. I have 12 months worth of data in seperate files (DBF0199.TXT, DBF0299.TXT, DBF0399.TXT, etc..)
which all use the same format. Is there a way to change the text import objects file name inside the package using an active script task or something?
Any help is greatly appreciated.
Thanks,
Todd

Hi All,
I'm having a problem in importing an Excel file into SQL server 2000.Here is the scenario with my data.
One of the column has got the mixed data which is putting null's in the SQL server table in some rows.I found in the MSFT Technet that it is a bug in SQL server 7.0/2000.The workaround for it ( according to MSFT ) is to get the data into text file and import into SQL server.
Now the question is , my data contains some currency fields and numeric fields in addition to the char and date fields. When I'm importing the table using DTS wizard , it is failing. I'm trying to use conversion functions like cdate and clng etc . Still the DTS is failing.
What I noticed is when I try to import into a table with data type varchar for all columns, it is working fine.But the data is of no use.
I would appreciate if any one can help me out in solving this problem.
Thanks,
Sammy.

Quick advice question. I import lots of text files -- many with 50 plus data columns. Few come with a table layout other than perhaps the first row having a set of column names.
When I go to pull them into SQL server the columns default to varchar 8000. Is anyone aware of a tool (as a part of SQL Server or otherwise) that can scan a column of data and recommend a data type and size.
Appreciate any recommendations.

Something I find myself wanting to do frequently is the traditional foreach loop looping through a directory of files and importing (which works great in SSIS) - Only I don't want to import data I have already imported.
In a previous job I used Perl for thing like this and the structure would be as follows:
For Each File:
1. Get filename and timestamp
2. Query db table with list of already imported filenames and timestamp. If Filename not in the table or is in table with older date return 1 to import or if file already imported return 0
3. Based on the result of step 2 either import or skip to next file.
Any recommendations how to do something similar in SSIS? I run stuck when I try to get the timestamp of the file and I also can't figure out how to do the conditional inside the foreach container... I am also open to other ideas on how to only import files I have not already imported.

Hi i'm new to DTS and need to be able to import a text file into a table each day.
The main problem I have is the file is datestamped so the name of the file changes each day.
Today it would be called file20070419.txt tomorrow it would be file20070420.txt. When I select a text file as a source I have to pick a valid file ??? how can I get round this ???

Hello Everyone and thanks for your help in advance. I am having a problem importing a text file into SQL Server 2005 and can't figure out where the issue is. The file is in CSV format with the text delimiter field as a ". When attempting to import the field into a SQL Server 2005 table, the import fails due to numerous truncation errors. I have tried importing into an existing table, but have also tried importing and allowing the import to create the table. I receive the same failures in both cases. For whatever reason, when allowing the import to create the table, each column is created as a nvarchar(50) even thought the column sizes vary widely. Oddly enough, when importing into a SQL Server 2000 table with the correct layout, the file imports perfectly fine, thus verifying there is nothing wrong with the data source. It also creates the table with appropriate column sizes in SQL 2000. I'm really at a loss as to what is going on. Any assistance woul dbe greatly appreciated. Thanks.

This is what I am going to do:
Everyday, there are users FTP the text files to a directory in the server. During the night, a job will be run to import these text files to a table.
First, the job need to read the file name, then open the file, read the first line and insert to the table until then end of the file. Then the second file will be read ... until no more file to be read.
I am using VB to read the file name and open the file, and my question is how to pass the file name to the second step which is in T-SQL?
Any experience to be shared in this area ?
Thanks,
Rachael

Quick Question!
If you have both invoice header lines and invoice detail lines in a comma delimited file, how can I get the data in the file to be imported into two different tables. I can produce a text file eg:
1,20,10/03/2002,39 High Street Any Town,,
2,20,Fluffy Slippers,2,Red,10.99
2,20,Pyjamas,3,Black,15.99
2,20,Trousers,1,Lilac,24.99
1,21,10/03/2002,11 Gibson Close,
2,21,Sandles,1,Black,12.99
2,21,Shoes,4,Blue,23.99
1,22,13/03/2002,45 Mill Street,
2,22,Womble Feet,4,White,16.99
2,22,Glass Slipper,1,Transparent,23.99
Lines with 1 in the first column should go in the InvoiceHeader table
Lines with 2 in the first column should go in the InvoiceDetails table.
I have tried with DTS but to no avial - ActiveX scrips in the Transform Data Task can only seem to access one data destination - it one table not two.
Any Ideas?
