How Do I Import A Flat File (.txt) To Sql Server Using Asp.net

Apr 3, 2008

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..

Programmatically Set A Flat File Connection Manager

Oct 6, 2006

Hello,



I need to know how I can programmatically set a Flat File Connection Manager's Column Delimiter value.

The Data Warehouse project I am working on, receives daily information feeds that could contain one of two delimiters. Which is just dumb...anyways, as it is now we have two seperate Data Flow Tasks which handle these two delimiters. Currently we have a script taks that "sneak previews" each incoming flat file to determine which delimiter it has, and direct our flow to the correct Data Flow Task to handle it.

I do not want to have to maintain 2 DFTs. How can I get around this problem?

Even if there is a way to do this by passing variables/setting expressions in the Flat File Connection manager, I would do that. Does not necessarily HAVE to be a pure programmatic approach.



ANY help would be greatly appreciated!

Feel free to email me at ccorbin@topcoder.com with any questions, or leave me some good news here :)

THANKS!

Configuring Flat File Connection Programmatically?

Mar 13, 2007

I am programmatically creating a package in c#. I need this package to contain a flat file connection manager. I have been successfully able to create the connection manager with the following code:


Package p = new Package(); //New package

ConnectionManager cm = p.Connections.Add("FLATFILE"); //Add a flat file connection manager

cm.ConnectionString = "C:DevmyTestFile.txt"; //Set up the connection string

At this point, I want to configure the flat file specific properties of the connection manager (RowDelimiter, HeaderRowDelimiter, etc.). The problem is that the properties collection of the ConnectionManager object is read only. I think I could access the inner object of the connection manager and set the properties in the following way:


ConnectionManagerFlatFileClass ffClass = (ConnectionManagerFlatFileClass) cm.InnerObject; //Get the inner object

ffClass .RowDelimiter = "{LF}"; //Set the properties here
Even if this would work, I do not like the solution b/c the BOL states that the ConnectionManagerFlatFileClass "supports the SQL Server 2005 infrastructure and is not intended to be used directly from your code". Does anyone know the "right" way to set these properties?
Many thanks in advance!

Import Flat File Into SQL Server 2005 Express

Jan 6, 2007

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

Dts Import Flat File

Mar 7, 2001

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.

Import From Flat File

Feb 7, 2008



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

SSIS Flat File Import Help

Aug 28, 2007

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.

SSIS - Import Flat File

Apr 17, 2006

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.

Import Flat File Automatically?

May 30, 2006

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

Question On Flat File Import

Aug 19, 2006

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

Advice On Flat File Import

Mar 5, 2007

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.

Flat File Import Question

Jul 20, 2007

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!

Import Flat File Data

Jul 3, 2007

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?

N00b: Best Way To Import Flat File With BIDS

Oct 25, 2006

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

Flat File Records Dropped During Import

Jun 7, 2007

Hello,
I am attempting to import a fixed width flat file into a SQL Server table. When I import the file, 704 records don't make it into the table. I know this because if I do the import with MS Access 2003 into an Access table, all of the records from the flat file make it into the table. The flat files have a .txt extension.

The only possible problem that I can see is that some of the rows in the flat file do not contain the full set of characters. When I do the import into SQL Server and create a table on the fly, I still end up 704 records short. There are no error messages during or after the import.

I suppose I could isolate some of the missing records, put them into a different file and try to import them to see what would happen. Other than that, how do I begin to troubleshoot this problem? Are there known issues where records can be dropped from a fixed width file?

Thank you for your help!

Struggling To Import Data From Flat File To Sql Db

Apr 1, 2008

Hello all,

We have been trying now for the past 2 days to import data from a flat file to sql server database but with no luck.

The real issue here is that one of the field names has a very long value.

As a result, the import fails because it is unable to truncate the value.

We really don't want the value truncated but we have not been able to import the entire data file.

We have used nvarchar(max) but it doesn't work.

Can someone please let me know if you have encountered this type of issue and how was it resolved?

Thanks in advance.

How To Import From Flat File And Update DateTime C

Jul 30, 2007

I have a a flat file that consists of 2 Columns of data that need to overwrite an existing Table that has 3 Columns of data. The Import fails because the 3rd column on the table is a Date stamp column with the Data Type of "smalldatetime" and does not allow Null data. If I were to delete this 3rd column from the table the import works great but I lose the DateTime column. How can I use the Import Wizard to import the first 2 columns from a text file and update the 3rd column with the date and time? The wizard does not seem to let me update a column unless the data for this column comes from the flat file. Please assist, thanx.

Import From Flat File Warnings And Errors

Feb 7, 2008



Hi,
I am trying to import from Excel file. So In between Excel file source and OLEDB destination I am using One Data Transformations to convert excel unicode characters to Sqlserver varchar.

Iam getting this following errors:
1)

Error: 0xC020901C at Data Flow Task, OLE DB Destination [382]: There was an error with input column "Copy of Zip" (615) on input "OLE DB Destination Input" (395). The column status returned was: "The value could not be converted because of a potential loss of data.".


Copy of zip is the Data Transformation column mapped Sqlserver Varcahr(200) column of Zipcode.
In excel file the Zip codes are like this:
78712-2344
78123
12345
87651-1234

2)

The column "State" needs to be updated in the external metadata column collection.
This is warning. This type of warnings are for all columns in excel file.

3) Intially I declared the Sqlserver table columns like this Varchar(100), then SSIS showing some warning like truncation of column State 255 characters to .. So I changed columns datatype from Varchar(100) to Varchar(500)? Why we need to change like this.

SSIS Import/Export Flat File

Oct 11, 2006

Firstly, I hope this question isn't asked too frequently but I found no existing reference to this situation....

I had a bunch of stored procedures in SQL 2k which imported and exported data to and from flat files using TEXTPTR, READTEXT, UPDATETEXT etc... The flat files were continuously changing so the filepath was a parameter for the sp.

The reason I used the pointer to flat files is because I didn't want to
load the files in memory before commiting them ie. with TEXTPTR and
UPDATETEXT I can import a 1Gb binary file 80000 bytes at a time and
keep (precious) memory usage down.


I was accessing this procs from a C# application.

Since these methods are going to be phased out by the guys at MS what is the best way of importing/exporting very large binary files in SQL 2005?

As far as I can tell SSIS requires a Flat File Source Manager object which needs a static filepath - not good.

Hope you can help,
Paul

Date Being Discarded In Flat File Import

Dec 21, 2007

I am importing from a flat file source that is pipe delimited. I have a few files that all follow the same format but now that I am dealing with subsequent files, they are reacting differently and the date is being discarded. I have opened the subsequent file into Excel without any column conversion issues. But whenever I run the package, about halfway through the dates become NULL. I have defined the field as DATE, DatabaseTimestamp, String (convert to Date using substring parsing method) and all of these yield the same results. Any ideas?

Flat File Import Performance Question

Aug 24, 2007

Hi there,

I have a question regarding 2 approaches importing data from a flat text file. I'm taking the approach suggested by Phil Brammer to use a checksum to see whether a row has exists, and if it does check whether it has changed.

http://www.ssistalk.com/2007/03/09/ssis-using-a-checksum-to-determine-if-a-row-has-changed

I would like to hear some opinions on 2 approaches:

1) Importing the data int a temp table first then do the data processing from the temp table.
Or
2) Importing the data by doing the data processing direcly from the text file without placing it in a temp table first.


A hunch told me that it will be faster doing approach 1 but I would like to hear some experienced opinions first

Best regards
Mike

Update Flat File Before Import SSIS?

Nov 29, 2006



Hi,

We have a csv file which contains a date field. The data in the field contains "0" as well as "dd/mm/yyyy". Is it possible to update all "0" to "01/01/1900" on import using SSIS.

Basically when we import the flat file now it falls over due to the destination table data type being datetime.

If this is not clear please let me know and i'll try and explain more?

Thanks for any help.

Export To Flat File Using T-SQL And Import To Another Machine

Jan 9, 2008



Hi,

I need to export some data from SQL 2005 to a flat file, The data and flat file names will be dynamic and will be be fired programaticaly so I can't use DTS or SSIS.

In SQL2000 I did it using bcp, but that's quite a security hole so I don't want to use external utilities. I'll need to do something similar on another machine to import the data as well.

I find it strange there's no easy way to do this!

Thanks.
