Loading Large Flat Files Into A SQL Database Using DTS
Dec 7, 2000
Here's my delema, I have a file that's 308 bytes wide by 5.7 million records. The record length is fixed and the position and width of the known within the record. When I run DTS I recieve this error Msg MS DTS flat file provide and Err Diesdription: error creating file mapping view: not enough storage is available to process this command. Then when I try to continue with the wizard, it will not allow me to separate the data into the format that I need. Is there any other way to import this file using DTS?

I have been tasked to do the following using SSIS.
We received two csv files each week and we would like to load these files to two different sql server tables using SSIS.
These files should be archived into a folder after each load.
How can I achieve this?

Hi ,
Is there any method by which I can divide the large flat file into certain number of small files keeping the header in each of the sub files?

I have several databases that have grown to 300 GB and would like to distribute the data into multiple files across multiple drives. Can I create a new database that is spread across the new drives and use a full backup to restore or am I stuck with unloading the data table by table?

Hello,
I am attempting to restore the database from within VB.NET application I am making the following 3 calls:
RESTORE FileListOnly FROM DISK = 'C:MyDatabase.dat'
USE Master RESTORE DATABASE MyDatabase FROM DISK = 'C:MyDatabase.dat' WITH NORECOVERY, MOVE 'MyDatabase' TO 'C:Program FilesMicrosoft SQL ServerMSSQLDataMyDatabase.mdf', MOVE 'MyDatabase_log' TO 'C:Program FilesMicrosoft SQL ServerMSSQLDataLDFMyDatabase.ldf', REPLACE
RESTORE DATABASE MyDatabase FROM DISK = 'C:MyDatabase.dat'
using SMO. This logic works fine with small *.dat files, however when using *.dat file of about 4Gb I get an error on the 3d restore database call:
ExecuteNonQuery failed for Database 'master'.
An exception occurred while executing a Transact-SQL statement or batch.
Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
Operator aborted backup or restore. See the error messages returned to the console for more details.

An exception occurred while executing a Transact-SQL statement or batch.

The same program/logic also works fine when I use MS SQL 2005 and it runs fine from MS SQL 2005 Query Analyzer for both 2005 and 2000 databases. There seem to be only problem with MS SQL 2000 from within VB.NET. Anybody has any idea? I'd appreciate any response. Thanks

Hi,
My scenario:
I have 4 different flat files types each having different no. of column, order of columns etc. I want to upload all the 4 types into the same destination table in the SQL database. Before uploading I need to apply transformation to each column in the flat files. The transformations could be like
1) Multipying the source column by 100
2) Put an if condition for 2 source columns and then select one column to be copied into the destination.
I have the flat files schema with me and also all the transformations that are required.
Question:
Can SSIS provide me with a component that can read the flat file schema and the transformations from the database and apply them to the source data and then upload it to the constant destination table? Can derived column transformation be provided with the input columns list and the transformation to be done on each dynamically?
Why I want this way?
In future there can be an addition of extra flat file formats and we want to keep the changes to the SSIS packages to he mininum. Just entereing the addiional schema and transformation details in the database should run the package on the new flat file successfully.
Thanks for your time.
Regards,
$wapnil

I have number of csv files in a folder, all of them with same columns, need to be merged into one table and imported to sql server.
-The first row of the csv file is a header.
-The csv files are updated everyday
-The destination table is replace by new table with new info in the csv.
-The new csv files can be created and old csv files may no longer exist, but we are only interested in information contain in current csv files in the folder.
-I need SSIS to combine all the csv files in the folder and merge into one table.
-Other issue is that the field names may change in csv, so can the SSIS package recognize the change in field name and made necessary change in destination table as well.
Any insight on this issues will be greatly appreciated?

Here's what I want to do -
Dynamically load a flat file from a dynamic source table-
The source table metadata is known via the SYSOBJECTS and SYSCOLUMNS tables- I can pull the column names, type and lengths from these tables based on the table name. (my goal is pretty simple- pull data from a table in our database, and save it down to a flat file)
Would this be enough to dynamically create the destination flat file? If so, how do I do it?
Thanks

I have a text file that loads just fine with DTS 2000, but in SSIS it does not seems to recognize the row delimiter. For example, most rows in the text file have 10 columns, but some have 8 columns. For those with 8 columns, the SSIS is adding the data from next row, not padding the columns with nulls. Please help...
Thanks in advance.

I tried to load a fixed width flat file with around 300,000 rows. However, only the first 8xxxx rows were loaded to the destineation table and the rest row were loading blank records. There was no error message showing during package execution. I've tried to split the file in half and the result was the same. So it wasn't the data file problem.
Would there be any buffering issue I need to cater for inside the package? Thanks!

Iam trying to load a RR Flat File(Ragged Right) into SQL Server DB Destination.
The file feeds the data into two tables and the logic looks like this..
If Position 30 = ''
Record Set goes into Table 1
Else
Record Set goes into Table 2
I have no clue where to start with my limited SSIS Exposure.. Any Ideas as to what i shud be starting with (Transformations)??
Thanks in Advance.

It seems I can do the type conversion in two place:
1. The advanced editor for flat file source => Input and output roperties. And I can set the output columns data type properties there.
2. Using a Data conversion box in Data flow transformation.
Any difference between these two? Which one should be used?

I have the misfortune of converting a DTS package to SSIS that loads a flat file that has a text fields that can contain embedded text delimiters ("), column delimiters (,) and even new lines (CR+LF i.e.,hex 0D 0A) in it. A sample line from the file is posted here, remember this is just one line though it shows as three lines, since the third field has embedded new line in it:
4,"Sam","EVP; MARKETING PRODUCT MANAGER ""Level I"",
Internet Sales / HELP
8005551212",100
If you open in excel it handles it perfectly showing four fields, as below, and this is what I want ( I cannot get it aligned right in the posting, just save the above line in *.csv and open to see what it should be):
4 Sam "EVP; MARKETING PRODUCT MANAGER ""Level I"", 100
Internet Sales / HELP
8005551212"
Now, SSIS errors on the embedded text delimiters and breaks into two or three lines based on which option I chose. I have tried few options based on postings in the forum:
a). Using undouble and undoubleout: Does not work when there are embedded column delimiters (,) in the text field
b). Modified undouble script posted by lvovg at http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1718225&SiteID=1. Handles the embedded column delimiters (,) perfectly, but the embedded new lines (CR+LF i.e.,hex 0D 0A) are breaking it.
Since, I am using the ragged right format to read from the file then use transform script on the line by lvovg, the line is already broken by the ragged right format at the embedded new lines, hence does not work.
Right now I am stuck. Can someone please help (anyone from MS) ? I am already baffled at the amount of coding required to convert a very basic ( and working ) flat file load DTS package to SSIS. I am willing to persist bit longer to convert this to SSIS, before I give up and stick with DTS and wait for a fix / workaround.
Thanks.

Hey Everyone,
I have a Data-Flow task embedded in a Sequence Container (does not fail component on error) on the Control Flow panel of the SSIS designer. This data flow task contains a connection to a Flat File Source -> A Data Transformation -> Into an OLE Db Destination.
The problem is that the Flat File isn't always delimited properly -> the client cannot be relied on to do this.
My question is when the delimiters are messed up, how can I capture the offending error row(s) from the Flat File Source?
What I've tried:
1) Set every column in the source flat file on error to: Redirect Row
2) Added a Script Transformation to pull the description and the record id out of the offending row
3) Added an Error file flat file destination to the end of the flow.
The package always fails on the Flat File Source and never Redirects the offending Row to the error output - I never see my onError Script Transformation go Green, Red, or Yellow - SSIS doesn't let it get there.
I'm really new to SSIS so sorry if this is a super basic question.
Here is the Error Text:
[Source - InventTable_csv [1]] Error: The column delimiter for column "RECID" was not found.
[Source - InventTable_csv [1]] Error: An error occurred while processing file "C:------InventTable.csv" on data row 15228.
[DTS.Pipeline] Error: The PrimeOutput method on component "Source - InventTable_csv" (1) returned error code 0xC0202092. The component returned a failure code when the pipeline engine called PrimeOutput(). The meaning of the failure code is defined by the component, but the error is fatal and the pipeline stopped executing.
[DTS.Pipeline] Error: Thread "SourceThread0" has exited with error code 0xC0047038.
I do have the MaxErrorCount set to 1 on the Data Flow Task but still think I should see my script task execute and a log entry be generated.
Any Ideas?

I have tried to load data from .unl file into exact replica of database in SQL server 2005 but failed.
I used this syntax, but it doesn't work:
LOAD FROM 'C:something\_something.unl'
DELIMITER '#' INSERT INTO dbo.table
I am sure about the delimiter, so that's not the problem. I just get the message that syntax is incorrect near the keyword FROM and DELIMITER.
Could someone please tell me what the correct syntax would be? Or what seems to be the problem?
Thx

In MySQL, I use "LOAD DATA INFILE 'my_path/data_file.txt'" to load datafrom a plain text file. Of course, the actual statement is a bit morecomplex once one considers the various options (e.g. comma delimited vstab delimited, record termination strings, &c.).My problem is that I have yet to find the equivalent within MS SQLserver. I did find a LOAD statement in T-SQL, but at first glance itseems to do something completely different.How does one normally load data from a plain text file into a table inMS SQL? This needs to be relatively efficient since, once inproduction, it will be used to load tens of megabytes of data into thedatabase (a feed from a data provider). Is it flexible enough to allowme to specify whether the fields are tab delimited vs comma delimited,optionally enclosed by quotes, record termination charactors, &c.?All I really need is direction to the right part of the T-SQL reference(MS SQL Server 2005). Anything else, such as examples, is icing on thecake.ThanksTed

I am trying to do here is to load different flat files to different tables:
For example, if the file name starts with "enrollment", then it goes to table "enrollment" table;
if the file name starts with "student", then it goes to "student" table.
For now, I created a foreach loop container for the each different files. So it ended up using several foreach loop containers. I am wondering if there is a way just to use one foreach loop containters to process the loading.
Anyone shed some light on this?? Thank you very much for your help!

I'm using the For Each loop container to load multiple XML data files into SQL Server, and noticing some peculiar behavior and need some advice.
The pattern I'm trying to accomplish is this: Iterate over a collection of XML files in a specific folder, loading each in turn into SQL Server. If the file has already been loaded, delete the records first before the load. After the load succeeds, move the file into an Archive folder.
To accomplish this, I've set up a For Eac Loop container using the For Each File enumerator, and retrieve just the file name and extension into a variable. The first task in this is an Execute SQL task that uses a SQL DML statement to delete records based on a field in the table containing the file name (DELETE FROM table WHERE PROG_NAME = ?), and map a variable to the parameter. The next task is the data flow task that uses an XML source using the variable as the file name, and SQL Server destination. I use a derived column task in between to plug the variable holding the file name into the PROG_NAME field. So far, so good. This works.
But now comes the peculiar part. I initially had the XSD files in the same folder as the XML files, but wanted to put them in their own directory, so moved them, and made the change to the XML source adapter for the new path to the XSD file. The next time I ran my package, it failed. For some reason, as the For Each Loop tried to iterate over the directory, it was using the XSD path assigned in the XML source instead of the path for the XML files. Unusual...
My question is, why when choosing the File name & Extension retrieval type (as opposed to the fully qualified name) will the task try to use the XSD location to find the files? Is my variable getting reassigned somewhere?

I have 6000+ text files, average size 400 kb, that I need to load into 1 table in Sql Server 2000. Does anyone know of an easy way to do this? I thought I would just write a little VB app to loop through all the files in the directory and insert the data into an existing table but there must be an easier way.
Any help would be appreciated.

Currently we are trying to load the xml files into sqlserver tables by using ssis 2012,We are getting xml files as a column in source table ,so we have to push these xml files into destination tables.
I'm following the below way to perform this activity

But We have standard XSD structure for all the xml files ,and if xml file matches the XSD structure then only we have to load ,else it should skip to next xml file.

I am pretty new to SQL Server 2005 and SSIS. I am trying to develop a package that will dynamically load files into SS2005 based on the contents of a configuration table. The configuration table (see below for example) contains the path to the file, a flag indicating whether or not to process the flag, the type of file (specifies the nature of data -- financial, order, etc.) and some parameters specific to each file.
FileName
ProcessFlag
Type
ExcelTab
Param1
C:File1.xls
TRUE
1
Sheet1$
C:File2.xls
TRUE
1
Sheet1$
C:File3.xls
TRUE
1
Sheet1$
C:File4.xls
TRUE
2
Sheet1$
C:File5.xls
FALSE
2
Sheet1$
C:File6.csv
TRUE
3
C:File7.txt
TRUE
4
Right now I basically have a seperate sequence for each of the file types. The task in each sequence are virtually identical with the exception of the the data flow source in the data flow task (since the source file could be .xls, .txt, .csv). The first sequence ran fine in isolation, but when I linked a second sequence I started getting a Package Validation Error:
DTS_E_CANNOTACQUIRECONNECTIONFROMCONNECTIONMANAGER
I use the same variables (FileName, ExcelTab) for each of the sequences, so I am not sure if that causes te error. I also tried changing the ValidateExternalMetadata setting to false, since the connection variable wont be applicable until that sequence is being processed. I am not sure where to go here ... should I rearchitect how the package all together?
Is there a better/most efficient way to to architect this package to handle the different file types (develop a package for each type which is called by a master package, create one package with a different sequence container for each type, etc).
Any help would be greatly appreciated!!

Hello everybody
I actually wrote a stored procedure (in xp_wrapper.dll) that is using a dll (original.dll) which uses a license file (no file extension).... clear? :)
Anyway.
All the required files are placed in the BINN dir of the server.
The problem is now, that original.dll can't find it's license file. It seems, that this file was not load by SQL Server.
How can I load this file into SQL Server's heap?
Yours
