Hello,
How do I import data from a text file into columns (DB_table) that I have created in SQL server 2005?
Data in text file does not have any commas, semicolons, or spaces in between them.
Each instance in the text file consists of 109 characters (real numbers).
I also know that first 4 numbers go in particular field, next 4 go in another field, and next 6 are particular field, and so on.
I also have created columns in a table respectively.
Here's a really annoying problem. Let's say you have a text file with 2 million rows.Delimiters all look good and rows are previewed well but the file has a missing row at say lin 1234567 - way deep in the file. When SSIS encounters the blank row, an error is raised and processing on the file STOPS! I verified this in by checking the SSIS log and have even developed an error routine to notify me via email when the error occurs (really cool if I do say so myself ). The main problem still remains - how to resume processing from the point of failure in the file? Any help is appreciated. Thanks.

I have a DTS package that copies data from a fixed width file and inserts it into a SQL Server 2000 table. These files are generated daily, and usually contain about 200k records.
Sometimes, the format of the file between two days can differ slightly. I can't tell if the problem lies with the length of the record string, or the string terminator. The record string is supposed to begin with 'D1'. One file (as viewed in Notepad) will contain the records each in its own row, and each row will start with 'D1'. Another file will show that the first record starts with 'D1', but then the next record does not begin on a new line. Instead the next record continues at the end of the previous record. In this case, 'D1' is preceded with an unrecognized character as if it to indicate a carriage return.
Anyway, in SSIS, when I configure the row width of the fixed width file in the flat file connection manager to 386, and the beginning of all the records are all on their own row, the data processes without a problem. When the records do not all begin on their own row, the data will process fine if I change the row width to 385.
I don't have to compensate for this in DTS. Between SSIS and DTS, both flat file connections are configured with a row delimiter of LF, and no text qualifier. Why will SSIS and DTS process these files differently?
Thank you for your help!

I cannot seem to get my flat file to write columns in error when inserting into a SQL table. I have tried a few examples from MS and did not get anything written to my flat file output. I have set the Source Error Output on this flat file and it uses a script task to created the error description and then write it to a Flat File Destination.
I am new to SSIS and have not had any formal training on it. However, I am very familiar with VS.Net/c# and SQL 2000 DTS - I need to get this working ASAP as there are 45 total flat files that need to be processed. Once I have this solved for one, the rest will follow suit.
If more details would help, I can provide them.
Kind Regards,

I am facing one process related issue.
I have one task in which i have to collect lots of .txt file having ## delimiter my requirement is to convert the delimiter from ## to comma and save the new file with .dat extension in different folder.
I have done all required process and run the application which should flow like collect source .txt file do Script component processing and create new .dat file with processed data in Data Flow task, but in my Task the Source and Destination start on same time and process start after words which cause empty file or some time a.txt file data stored in b.dat file where as a.dat file is completely empty.
The process should flow in sequence but behavior is totally against the process, i am using Foreach Loop Container for pick up each file.
Hi,
I am testing SSIS and have created a Flat File Destination. I defined the Flat File Connection as New for the first time and it worked fine. Now, I would like to go back and modify the Flat File Connection in the Flat File Destination Editor, but it allows only to create a New connection rather allowing me to edit the existing one. For testing, I can go back and create a new connection, but if my connection had 50-100 columns then it would be an issue to re-create it from scratch.
Did someone else faced this issue?
Thanks,

Hi,
I have a situation where a tab limited text file is used to populate a sql server table.
The tab limited text file comes from a third party vendor. There are fixed number of columns we need to export to the sql server table. However the third party may add colums in the text file. Whenenver the text file has an added column (which we dont need to import) the build fails since the flat file connection manager does not create the metadata for it again. The problem goes away where I press the button "Reset Columns" since it builds the metadata then. Since we need to build the tables everyday we cannot automate it using SSIS because the metadata does not change automatically. Is there a way out in SSIS?
I am transferring data from an OLEDB source to a Flat File Destination and I want the column width for all of the output columns to 30 (max width amongst the columns selected), but that is not refected in the Fixed Width Flat File that got created. The outputcolumnwidth seems to be the same as the inputcolumnwidth. Is there any other setting that I am possibly missing or is this a possible defect?
Any inputs will be appreciated.

Hi all,
I m using SSIS and i am transfering the data from Flat File Source to the OLE DB destination File. The source file contain some corrupt data which i am transfering to the other Flat file destination file.
Debugging is succesful but i am not getting any error output in the Flat file destination file.
i had done exactly which is written in the msdn tutorial of SSIS.
Plz tell me why i am not getting the error output in the destination flat file?
thanx
First, a couple of important bits of information. Until last week, I had never touched SISS, and therefore, I know very little about it. I just never had the need to use it...until now. I was able to convert my first 3 flat files to SQL2005 tables by right clicking on "SISS Package" and choosing "SISS Import and Export Wizard". That is the extent of my knowledge! So please, please, please be patient with me and be as descriptive as possible.
I thought I could attach some sample files to this post, but it doesn't look like I can. I'll just paste the information below in two separate code boxes. The first code box is the flat file specifications and the second one is a sample single line flat file similar to what I'm dealing with (the real flat file is over 2 gigs).
My questions are below the sample files.

As you can see, each entry could have any number of records and multiples of some of the record types, with one exception, every entry must have a "01" record and can only have one "01" record. Oh, and each record has a length of 400.
I need to get this information into a SQL 2005 database so I can create a front end for accessing the data. Originally, I wanted one line for each account and have null values listed for entries that don't have a specific record. Now that I've looked at the data again, that doesn't look like a good idea. I think a better way to do it would be to create 5 different tables, one for each record type. However, records 2 through 5 don't have anything I can make a primary key. So here are my questions...
Is it possible to make 5 tables from this one file, one table for each of the record types?
If so, can I copy the Account number in record 01, position 13-19 in each of the subsequent record types (that way I could link the tables as needed)?
Can this be done using the SISS Import and Export Wizard to create the package? If not, I'm going to need some very basic step by step instructions on how to create the package.
Is SISS the best way to do this conversion or is there another program that would be better to use?
I know this is a huge question and I appreciate the help of anyone who boldly decides to help me! Thank you in advance and I welcome anyone's suggestions!
Hello I have some flat files that contain CSV records with different number of fields but the first 4 fields of each record type are the same of each re. eg there would be an entry of one record that has eight fields and another that has 6 fields. Which of the items in the toolbox can i use to filter the records based on the entry in the first 4 fields so i can process the filtered records.
Thank you

How can I take this example Flat file and parse out each section to a new flat file? Each section starts with HD (header row)
http://www.webfound.net/flat_file_example.txt
e.g. an example output file based on above (cutting out the first section) would be:
http://www.webfound.net/flatfile_output.txt
Also, I'll need to grab a certain value in each header row (certain position in the 100 byte header row) to use that as part of the filename that's outputed. I assume it would be better to insert these rows into a temp table then somehow do a search on a specific position in the row...but that's impossible? The other route is to insert each row into a temp table separated out by fields but that is going to be too combursome because we have several formats to determine separation of fields based on the row type so I'd have to create many temp tables and many components in SSIS when all we want to do is again:
1) output each group (broken by each header row) into it's own txt file
2) use a field in the header row as part of the name of the output txt file (e.g. look at the first row, whcih is a header row in flat_file_example. txt. I want to grab the text 'AR10' and use that as part of the filename that I create
Any suggestions on how to approach this whole process in SSIS...the simplest approach that will work ?
I have an int field - that will hold number for an ordering system. It's a databound field to a textbox in a grid, I want the default to be empty, however not all fields are required so i may have 1-6 as bound values, and the rest should fall in line behind them - the only thing i can think of to do is default the values to 9999 so they come after 1,2,3,4,5,6 etc... I don't like seeing 9999 in my bound fields.
thanks for any suggestions you may have.

hi,
i have a field of type int, that when returning results, needs to be in ascending order. the problem is that this field can also contain null values. is it possible to return the results in ascending order but have all the null values at the bottom of the result table?
thanks,

How do you get the following to work properly?
WHERE Location = 'John's House'
The apostrophe between n and s has me stumped. Thanks.
I am fairly new to SQL server and am having a problem getting the SQL backup or "dump" to do what I need it to do. My desired end result is to have a database backup every night to a backup device on the same server as SQL is running, and keep one weeks worth of databases in the backup device, overwriting the database backup from 7 days before. This device is then transferred sometime later to another server using the NT AT scheduler. The first time I tried to accomplish this I used Enterprise manager to schedule a full backup to be run each night at midnight. The backup device was set to be initialized and retained for 7 days. This procedure worked once, the first night. There after it failed. In looking at books on line it said that I needed to change the transact -SQL command from INIT to NOINIT as the INIT instruction was the cause of the failure. I changed the statement in the Scheduled Task manager to NOINIT. That seemed to do the trick as I checked the backup device each of the next few days and saw that it was indeed performing the backup and retainng the databases. A week later I checked the backup device again and found that it is still adding database dumps to the file, but it is not overwriting the dumps that are 7 days old. I am told that I need the INIT statement in the dumpdevice command in order for the RETAIN DAYS = command to kick in. However, this did not work before. I can not continue adding to the dump device as it will get too large and take up too much disk space on the server. The only way I can get the device to a reasonable size is to do a backup and initialize the device, which gets rid of all of the older databases. This seems like a catch 22. Is there any way I can make this work. I am running SQL 6.5 on the latest service pack (5a). Any help would be greatly appreciated.

I want the error file to be created ONLY if there is any error while dumping the data into destination DB. But , the issue is, the error flat file is being created inspite of No error while dumping the data from Source to Destination.
View 5 Replies View RelatedNeed to know how I can get the dynamic filename created in the FlatFile destination for insert into a package audit table?
Scenario: Have created a package that successfully outputs Dynamiclly named flat files { Format: C:Test’Comms_File_’ + ‘User::FileNumber’+’_’+Date +’.txt’
E.g.: Comms_File_1_20150724.txt, Comms_File_2_20150724.txt etc} using Foreach Loop Container :
* Enumerator Set to: “Foreach ADO Enumerator” with the ADO object source variable selected to identify how many total loop iterations there are i.e. Let’s say 4 thus 4 files to be created
*Variable Mappings : added the User::FileNumber – indicates which file number current loop iteration is i.e. 1,2,3,4
For the DataFlow task have a OLDBSource and a FlatFile Destination where Flat File ConnectionString is set up as:
@[User::Output_Path] + "Comms_File"+ @[User:: FileNumber] +"_" + replace((DT_WSTR, 10) (DT_DBDATE) GETDATE(),"-","")+ ".txt"
All this successfully creates these 4 files:
Comms_File_1_20150724.txt, Comms_File_2_20150724.txt, Comms_File_3_20150724.txt, Comms_File_4_20150724.txt
Now the QUESTION is how do I get these filenames as I need to insert them into a DB Audittable. The audit table looks like this:
CREATE TABLE dbo.MMMAudit
(
AuditID INT IDENTITY(1, 1) NOT NULL,
PackageName VARCHAR(100) NULL,
FileName VARCHAR(100) NULL,
LoadTime DATETIME NULL,
NumberofRecords INT NULL
)
To save the Filename & how many records in each file in our Audit Table, am using an Execute SQL Task and configuring it as this:
Execute SQL Task
Parameter mapping - Mapped the User Variable (RecordsInserted) and System Variable( PackageName) to Insert statement as shown below
SQLStatement: INSERT INTO [dbo].[MMMAudit] (
PackageName,NumerofRecords,LoadTime)
(?,?.GETDATE)
Again this all works terrific & populates the dbo.MMMAudit table as shown below BUT I also need to insert the respsctive file name – How do I do that?
AuditID PackageName FileName NumberOfRecords
1 MMM NULL 12
2 MMM NULL 23
3 MMM NULL 14
4 MMM NULL 1
I need find out the number of columns in flat file before i process that particular file.I have file name in @filename variable and file path is @filepath variable.But do not not that how i will check the column name in before i will process that file.
@filePath = C:DatabaseSourceFilesCAHCVSSourceFiles
And i am using for each loop container to read the file one by one and put the file name in @filename variable.and my file name like
Product_20120607060930.txt
Product_20130708060930.txt
[code]....
Now what i have to do is i need to make sure that ID,Name,City,County,Phone is there in flat file.if it is not there then i have to send mail to client saying that file is not valid.I need to also calculate the size of flat file.
What is the easiest way to accomplish this task with SSIS?
Basically I have a stored procedure that unions multiple queries between databases. I need to be able to export this to a text file on a daily basis and add a total records: row to the end of the text file.
Thanks in advance for any help.
Hello Experts,
I am createing one task (user control) in SSIS. I have property grid in my GUI and 2 buttons (OK & Cancle).
PropertyGrid has Properties like SourceConnection, OutputConnection etc....right now I am able to populate Connections in list box next to Source and Output Property.
Now my question to you guys is depending on Source Connection it should read that text file associated with connection manager. After validation it should pick header (first line of text file bases on record type) and write it into new file when task is executed. I have following code for your reference. Please let me know I am going in right direction or not..
What should go here ?
->Under Class A
public override DTSExecResult Execute(Connections connections, VariableDispenser variableDispenser, IDTSComponentEvents componentEvents, IDTSLogging log, object transaction)
{
//Some code to read file and write it into new file
return DTSExecResult.Success;

throw new Exception(String.Format("Invalid task element '{0}' in LoadFromXML.", node.Name));
}
else
{
try
{
_sourceConnectionId = node.Attributes.GetNamedItem(Property_SourceConnection).Value;
}
catch (Exception ex)

Hi all,
In a foreachloop, I am inserting records into a flat file which is working fine. But the thing is that as the file grows, it takes longer for it to locate the EOF(End of File) of the flat file so as to insert the records.
I have around 70-100 lines written to the file at each loop and there are more than 20k records to be looped. wihich means that at the end I should be having 1400k - 20000k line in the text file.
One solution would be to insert the records at the start of the file itself so that it does not has to lookup the EOF each time before writting.
Another would be to generate separate files and then merge it.
Any idea how can this can be done?
Beside this I have to zip the file and then SFTP to a given address.
Any suggestion or help would be welcome.

Hi,
I have a flat file, comma-delimited, with strings in double-quotes.
In the connection manager for the file, I have specified that the Text Qualifier = ""
However, in the preview tab, it still shows the strings as surrounded by the quotes, e.g. "mycol1" whereas it should show mycol1 without the quotes.
Next, when I examine the data in the database after the load, it's messed up there also.
"mycol1" ends up in the database as "mycol1
"mycol2" ends up as "mycol2
This is not right.
I have format set to delimited, header row delimiter crlf, etc.
Any ideas?
Thanks
Hi,
I have a package A which is copied from another existing package B as most of the data structure and ETL mappings are same.
What I need to change in Package A is to change the file in Flat File Connection Manager. I can change it in the conneciton manager editor. However, it is automatically changed back to the previous one everytime when I try to Save All or run the package.
I also tried to copy/paste this Flat File Connection Manager in the same package but samething happen. The package file is not set 'Read Only" so anything else can Saved well except for the File name in connection manager.
Is this a bug? It would be very appreciated if anyone can give me any idea about this.
Thanks,
Jenny

Hello DBA's:
I need to extract a particular file from our AS 400 system on a daily basis and do some processing on it. Also I want to do the daily processing only on those records that have been added/updated since the initial load.
Here is the approach and possible implementation.
Approach
I have the DB2 source data containing 10 columns (Col1 to Col5 together form the key) and the rest are attributes. I am interested only in the key and two attributes. So I load my table with only Col1 to Col7 ( 5 for key and the two attributes). I then do my processing on this table.
Here is the implementation given by a member of dbforums -
You'll then have to deal with 3 potential actions,
INSERT: New records on the file.
DELETES: Records that don't exists.
UPDATES: Records that are on the file, but attributes have changed.
You had given me this code template.
CREATE TABLE myTable99 (
Col1 char(1)
, Col2 char(1)
, Col3 char(1)
, Col4 char(1)
, Col5 char(1)
, CONSTRAINT myTable99_pk PRIMARY KEY (Col1, Col2))
CREATE TABLE myTable00 (
Col1 char(1)
, Col2 char(1)
, Col3 char(1)
, Col4 char(1)
, Col5 char(1)
, CONSTRAINT myTable00_pk PRIMARY KEY (Col1, Col2))
GO
INSERT INTO myTable99(Col1,Col2,Col3,Col4,Col5)
SELECT '1','1','a','b','c' UNION ALL
SELECT '1','2','d','e','f' UNION ALL
SELECT '1','3','g','h','i' UNION ALL
SELECT '1','4','j','k','l'
--DELETED
INSERT INTO myTable00(Col1,Col2,Col3,Col4,Col5)

Can anybody look at My comments and answer them or revise this code template if need be?
Brett Kaiser - I sent you an e-mail on this. Can you respond to it when time permits.
Thanks
I have a windows service that connects to a regular sql server 2005 database and basically bulk copies data into a SQL express database. Afterwards, I just want to copy the MDF file into a different directory. I keep getting the "Process cannot access file because it is being used by another process" error. I've tried changing the connection strings but nothing seems to work. I'm closing the connections in the code as well. Here is the code. Any thoughts or help would be appreciated. RefreshDB calls Sync 3 times and if all three calls are successful, it attempts to copy the database file to the specified location. This is where I get the error.
Public Function RefreshDB() As Boolean
Dim success As Boolean = True
Dim tables() As String = {"Job", "Equipment", "PMScheduled"}
For Each tableName As String In tables
If SyncTable(tableName) = False Then
success = False
Exit For
End If
Next
If success Then
'copy the new database to the target directory
Try
File.Copy(My.Settings.DBFilePath, My.Settings.TargetDirectory + "EMField.mdf")
Catch ex As Exception
My.Application.Log.WriteEntry(ex.Message + "(RefreshDB)", TraceEventType.Critical)
Return False
End Try
End If
Return success
End Function
Private Function SyncTable(ByVal tableName As String) As Boolean
Dim reader As SqlDataReader
Dim sourceViewName As String = String.Format("EMField{0}View", tableName)
Dim connectionString As String = My.Settings.EMFieldConnectionString
'insert the path to the database into the connectionstring
connectionString = connectionString.Replace("[DBFilePath]", My.Settings.DBFilePath)
Try
'clear the target table first
Using targetConnection As New SqlConnection(connectionString)
Using truncateCommand As New SqlCommand(String.Format("TRUNCATE TABLE {0}", tableName), targetConnection)
targetConnection.Open()
truncateCommand.ExecuteNonQuery()
targetConnection.Close()
End Using
End Using
'create a datareader from the source database
Using sourceConnection As New SqlConnection(My.Settings.EMLiteConnectionString)
Using readCommand As New SqlCommand(String.Format("SELECT * FROM {0}", sourceViewName), sourceConnection)
sourceConnection.Open()
reader = readCommand.ExecuteReader
BulkCopy(tableName, reader, connectionString)
reader.Close()
sourceConnection.Close()
End Using
End Using
Return True
Catch ex As SqlException
My.Application.Log.WriteEntry(ex.Message + "(sync)", TraceEventType.Critical)
Return False
End Try
End Function
Public Sub BulkCopy(ByVal tableName As String, ByRef reader As SqlDataReader, ByVal connectionString As String)
Try
'bulk copy from source to target database
Using bulkCopy As New SqlBulkCopy(connectionString)
bulkCopy.DestinationTableName = tableName
bulkCopy.WriteToServer(reader)
bulkCopy.Close()
End Using
Catch ex As SqlException
'throw exception back to calling sub
Throw ex
End Try
End Sub
Hi,
View 5 Replies View RelatedHi,
I have a task to traverse a folder of CSV files of same format and then populate into one sql server table.
Is there a way where I can change the source CSV file name runtime using FOR EACH loop container for flat file connection manager ?
any help would be much appriciated.
Thanks,
Furrukh Baig
Hi,
I'm attempting to use a variable to define the file name in my flat file connection (for error files in my SSIS package).
I have it defined as follows:
@[User::ValidRootFolder]ConditionConditionSourceError.csv
However it throws an error 'the filename, directory name, or volume label syntax is incorrect'.
If I put the value of the variable in explicitly it works, so I know my variable name is correct - am I just not calling the variable properly?
Thanks
Hi,
we have one requirement to run the package daily basis.
The package should run at specific time on that day.
we are using windows schedular for that.
we will have one new flatfile everyday.
Is there any process to attach this file to flat file source dynamically?
The requirement is,
The flat file should be able to read the new flatfile everyday.
we have no option change it manually, the flatfile source should have to take the file automatically at that time.
So that it can take that flatfile and load it into database table.
