Importing Text Files To Sql Server Using Asp.net/Vb.net

Sep 20, 2004

Hi,

Can anyone help? Need to upload a text file to a sql database but keep getting errors.

I'm creating a page that will allow users to to bulk import and update to a MsSql database. The users provide a text file every so often with new/update information. So i want to use a DTS package to transform the infomation, and create a table in the database, then check against existing/non existing records, if the record exist, update it, if not insert it. I'm using Visual Studio.Net, ASP.Net and coding in VB.Net.

Anyone know where i can find documentation/code regarding the above?

I will be greatful for any help.

Importing Text Files Into SQL Server - Some Problems

Mar 22, 2007

Hi all,

Sorry if this is in the wrong forum but i didn't know if i should put it in the Data Mining forum.

My problem is two fold.

Scenario:

I have 11 text files with standard data format. They range in size from 20megs to 300+ megs (containing 100's of thousands of lines of data)

I build a simple DTS Package to automate the importing of the text files into a database table with the same format as the text files.

Running the files through my DTS produced errors on all files. The error was :
Too many columns found in the current row; non-whitespace characters were found after the last defined column's data.

The error also gave an approximate position of the problem row. So i opened up a text editor that can handle large files and took out about 5000 records before and after the problem area. So i now had a new test file that had 5000 records and contained what "should" be the problem row. I ran this file and it imported correctly. It did not produce the error that i got previously. However it did import things incorrectly. Going through only one of the files i found several rows (over two dozen) that had half the data on one row, then the other half on the other row. Obviouslly there is a problem here with the way the data was exported. I wanted to know if anyone knows of any programs i can get that will analyze these text files for inconsistencies. I have considered writing one in C# but want to see if there is something already out there that can help me.

Basically i need to look at these text files and find Rows that are "incomplete"

the files come from a unix based system, use LF for row delims and Chr(29) for Column delimiters.

any ideas?

thanks,

mcm

Problems Importing Text Files With Double-quotes As Text Qualifier

Jul 14, 2006

I have text data files from a third party and they use comma as field delimiters and enclose the text for each column in double-quotes. Not a problem for most of the data files until they start sending files where there is " within the column values. SSIS package fails with the error:

The column delimiter for column "Column 1" was not found.

Any ideas on how to resolve this issue will be greatly appreciated.Thankspcp

Importing Text Files

Apr 10, 2001

Hi,

I want to import multiple text files into a single table. I know I have to use BCP or DTS. But, I want import all files at once, instead of one at a time. And the file names are in sequence, viz. file1, file2, file3 etc.
Can anybody tell me, How I can achieve this.

Thanks

Importing Text Files

Sep 19, 2001

I have to import 18000 text files into a sql database.
Each file contains 10 fields and around 5000 records.
I am currently doing this with DTS.

What I am wondering is this: Is DTS the most efficient i.e. quickest way to import all this data. Bearing in mind there is about 90 million records to import in all.

I would appreciate the benefit of somebody elses experience when dealing with this type of thing.

Cheers,

Help Needed With Importing Text Files

Jun 6, 2005

I have a load (180,000+) of text files whose contents need to go into a SQL server database.Whats the best way of doing this? Using a c# console program and if so, using FileStream or StreamReader? Or using a feature of SQL server itself. The text files themselves are less that 1k and are literally less than 200 characters.The problem is, I've tried a WinForm and although I can detect what files are there, as soon as I attempt to open one for reading, everything stops working and won't insert anything to the database.

Importing Text Files - DTS Help Needed

Oct 31, 2006

Hi allCould someone help me with the following problem? Hours of googlingyesterday couldn't get me the answer. I'm using SQL 2000 and DTS andtrying to import a huge fixed width text file.File is >1m rows and >200 columns and is defined by a proprietory (i.e. notbcp produced) format specification of the formName Start LengthFld1 0 20Fld2 19 5Fld3 24 53and so on.Tbe only way I've found to define the columns so that DTS can import thefile properly is to go through the wizard and click on the starts of eachcolumn. I don't want to use bcp if possible (I did enough of that onSQL7) - but surely there's a way to get DTS to read from a format file so Idon't have to click 200 times (with all the ensuing errors I could make).Any help greatly appreciated.CheersRob

Importing Text Files And Converting Datatypes

Oct 8, 2004

Hi ya... About to tear my hair out.

I thought i fixed this problem, as it WORKED about two days ago, but now I'm getting errors.

I have a series of text files, some are delimited, some are fixed width. I previously was able to import these files thru a dts package by creating the table in a stored procedure. Exple:
CREATE TABLE [Pol_Dump073104]
(
[Product_Type] varchar (12) NULL,
[Benefit] float NULL,
[Base_Premium] varchar (12) NULL,
[Rider_Premium] float NULL,
[Contract_Value] float NULL,
)

I then import the text file into the table and then cast the float datatypes as money in a select into statement to do aggregate functions on the money fields. this worked previously, but now I'm receiving this: 'Error converting datatype char to money.' I tried to convert to float and received the same error, only with float where the word money was.

Please help! :mad:

Thanks

Importing Text Files With Different Number Of Columns

Oct 6, 2007

Hi!

I have a bit of a problem with importing (DTS Package) from a text file into an existing DB.

The file has no column names and every file only contain 1 row. This row varies in number of columns.

My first thought was to create a table with the maximum numbers oc columns that can appear in the text file.
An example:

Table with 4 columns; Col001, Col002, Col003 and Col004

The first text file:
123,Peter,Ocean Street,NY

The second text file:
356,John,Park Avenue

My aim is that the second file should append to the table, leaving Col004 as (NULL)

Any ideas how to get this to work?

Expekt

Problem Importing Text Files With Binary Zeros (0x00) Via SSIS(SQL2005). It Is All Fine When Using DTS(SQL2000) Though.

Apr 24, 2008

Hi.

There is a "text" file generated by mainframe and it has to be uploaded to SQL Server. I've reproduced the situation with smaller sample. Let the file look like following:
A17 123.17 first row
BB29 493.19 second
ZZ3 18947.1 third row is longer
And in hex format:
00: 41 31 37 20 20 20 20 20 �� 31 32 33 2E 31 37 20 20 A17 123.17
10: 66 69 72 73 74 20 72 6F �� 77 0D 0A 42 42 32 39 20 first row��BB29
20: 20 00 20 34 39 33 2E 31 �� 39 20 20 73 65 63 6F 6E 493.19 secon
30: 64 0D 0A 5A 5A 33 20 20 �� 20 20 20 31 38 39 34 37 d��ZZ3 18947
40: 2E 31 20 74 68 69 72 64 �� 20 72 6F 77 00 69 73 20 .1 third row is
50: 6C 6F 6E 67 65 72 �� longer

I wrote "text" in quotes because sctrictly it is not pure text file - non-text binary zeros (0x00) happen sometimes instead of spaces (0x20).

The table is:

CREATE TABLE eng (

src varchar (512)

)

When i upload this file into SQL2000 using DTS or Import wizard, the table contains:

select src, substring(src,9,8), len(src) from eng
< src ><substr> <len>
A17 123.17 first row 123.17 25
BB29 493.19 22
ZZ3 18947.1 third row 18947.1 35

As one can see, everything was imported, including binary zeros. And though SELECT * in SSMS truncates strings upon reaching 0x00's, still all information is stored in tables - SUBSTRINGs show that.

When i upload this file into SQL2005 using SSIS or Import wizard the result is following:
< src ><substr> <len>
A17 123.17 first row 123.17 25
BB29 4
ZZ3 18947.1 third row 18947.1 25

This time table is half-empty - all characters behind binary zeros in respective rows are lost.

I stumbled upon this problem while migrating my DTSes to SSIS packages. Do you think there is some workaround, or i need to turn on some checkbox or smth else could help? Please...

Linked Server To Text Files: Is Possible To Detect Changes Made To Those Files? (SQL Server 2005)

Sep 3, 2007

Hi gurus,

I've created a linked server (and set up the corresponding schema.ini file) in order to perform bulk-inserts from some CSV text files into SQL tables (from my standpoint the text files are just for reading purposes). The linked server works fine (I can select the data in the files without a problem).

Now the question: is possible to automatically detect when one or more of those files change in order to start the import process automatically? Something like having a trigger created on the CSV files Or there's no easy way to do that so I have, to say something, to create a Job that periodically checks if the files have changed programatically (say, recording each file's timestamp everytime is imported and comparing the recorded value with the current one, or whatever)?

Thanks a lot in advance!

Importing Csv Files To SQL Server Express

Nov 22, 2007

Hello,

I receive 4 .csv file downloads periodically (3 times per day) via email from our corporate database. I open each file in Excel, save as excel files, import to Access, replace the previous tables...run action queries, generate reports combined with production data from CSRs and supervisors. ALL DONE MANUALLY!!!

Here's where I am now:
-I've recently switched over to SQL Server Express.
-Used SSMA to bring tables over from previous Access database.
-Exercised the option to LINK these tables to the original Access database.(I'll explain why in a moment)
-Created ADPs for front end data entry use.
-Imported old Access database forms into the new ADPs previously used in Access.
-Connected to the new Server Express.
-I've eliminated my concurrent user problems by doing this.
HOWEVER, I am still bound to using old Access/Jet database to generate reports based on periodic downloads from corporate .csv files.

Here's the question:
What is the best way to import the csv files being sent to me via email into SQL Server Express? I've tried DTS. Seems to me you can't save AND actually use the packages later since it's the Express edition..... Importing manually 4 files, 3 times per day is a very tedious option I'd like to avoid. Any ideas?
Oh, by the way. Corporate has told me they would be willing to post the files to an FTP site instead of emailing the files. That's about as much help as I'm going to get from them. Can SQL Server Express be set up to run stored procedures (triggers) on a hot folder?
Thanks for your help.

Importing Binary Files Into Sql Server Database

Sep 26, 2005

I work for a company that makes heat transfers for the imprinted apparel market. We're developing a database of merchandise images for all of our non-design inventory. Using Access we're going to be inserting thumbnails of psd (photoshop) files. We're wondering if there is any way to import multiple psd's into the sql server database into matching records like matching a column named "filename" and the actual filename of the file without having to upload each file individually. We want to be able to dump the files from the database of the matching records, also. This way, once our catalog designer has found which designs they need to put into the new catalog, it will dump the psd's for us. The same for our staffer who does color separations.

Any suggestions out there? If you need me to post further of what we're trying here, I will. This is for the bossman.

Importing Excel 2007 And/ Or DBF Files Into SQl Server 2005

May 12, 2007

Greetings,

I'm having a tough time importing some of my legacy database into sql.
I have a number of dbase (IV) files I need to get into SQL. I have tried building a SSIS package with either an foxpro oledb connection or a jet 4.0 one, none of them work bec. of inconsistencies in the data format in my tables (e.g. date fields, etc).

I have tried to save the .dbfs as excel 2007 files, taking advantage of the larger space that comes with '07. Problem is you can't use the import/export wizard with 2007 for some reason and I haven't been able to create a package with the access 12 oledb as I have read.

I have to get some crucial data out of that old system and into the new one and I can't seem to be able to import them properly.

Any hints on what I should do ? (maybe I'm doing something awfully wrong)

Thank you for taking the time to answer my question,
Val

Problem Importing Csv Delimited Text File Into A Sql Server 2005 Table

I am using the Bulk Insert command and trying to import a CSV delimited text file into a table and I am having problems with the quote field delimiters ", " The command below works but it takes in all the "" quotes as well and the field delimiter comma , works only if the commas are the separators only. If I have a comma within a address field for example then the data gets imported into the wrong fields. What can I use to identify that the text qualifier is ". I don't see where I can use the bulk insert command to determine this. Is there another command that I can use or am I using this command incorrectly. I thank you in advance for any response or suggestion you may have.

DTS: Copying Data From Text Files To A SQL Server Table

Sep 10, 2001

Hi all,

I got a situation here.....

From a source table (in SERVER1) I get ids of candidates and from another source (in SERVER2) I get their CVs (text files stored in various Folders). My destination table (in SERVER3) has two fields, CandidateId & CandidateCV.

I have to transfer the data in above fashion for nearly 1 million records.
How can I write a DTS package which picks up the text file from SERVER2 based on the CandidateId which comes from SERVER1? Probably I need some kind of looping mechanism which changes the candidate id & his CV file.

Can anyone help???

Thanks...

I have to export the table data from my databse into text files as I nedd to put it in Informix database using a sheel script. Is there a way by which I can do this.

Is there any other way by which I can put the data from SQL Server to Informix.

Any takers,

Thanking you in advance.

Bye for now,

Himauhu
