DTS Re-uses Old Text File Input
Dec 22, 2004
Hi All,
A simple DTS job I have is giving me fits. It is a straight copy column job from a pipe delimited text file into a table. The input file comes from a mapped drive linked to a shared filesystem on a sun solaris box.
The typical scenario. I run the DTS job to load 8000 rows from the input text file. Job succeeds.
A week later, the text file is updated with 9000 new rows. I run the DTS job with no changes and it loads 8000 rows from last week.
I reboot my Win XP pc and run DTS again. It now loads the 9000 new rows.
I tried mapping to a UNC to no avail.
Is it buffering the old file somewhere? I need help.
current environment:
SQL Server 2000 with all latest SP's and patches
Windows 2000 Server with all latest SP's and patches
Drive 'G' mapped to a shared filesystem on sun solaris via Samba?

Hi,
I'm wondering if there is any way to get SSIS to notice, in the Flat File Source, that a "Ragged right" text input file has a record that is too short to populate all the specified columns.
I am reading data from a file that is supposed to be fixed length records, but record 193,591 (out of approx. 500,000) is 20 bytes short of the fixed length (60 bytes). So I changed the input to "ragged right" and found that I can thereby continue to read the file, and load the data (after setting the "maximum errors" to a number greater than the initial "1"). (Without this change to "ragged right", every record after the bad one was "out of synch" with the column arrangement -- so they never made it into the database table destination.)
But the "failures" I am now getting are during the Data Conversion step, when I try to convert some columns to integers (from text, in the input stream). And by looking at the data with a "Redirect Row" setting for the Data Conversion step, I am able to see that the Flat File Source is reading "right past the end of the row."
Is there a way to get the Flat File Source to honor the CR-LF record terminator, and decide that some text columns should contain "nothing" (NULL or zero-length strings), rather than the bytes that contain the CR-LF and the initial text from the next record? Can this somehow be noticed as an error condition?

Hi,
Im a programmer for an university webportal which uses php and msssql.
When an user creates a new entry and his text is too long the entry is cut short and weird characters appear at the end of the entry.
For example:
http://www.ttz.uni-magdeburg.de/scripts/test-messedb/php/index.php?option=show_presse&funktion=presse_show_mitteilung&id=333
How can I set the text limit to unlimited?
Could it be something else?
Is there a way of splitting an entry to several text fields automatically?
Thanks in advance for any help you can give me,
Chris

Hi,
I'm pretty new to ASP.NET and VB, but I'm working on a project which is essentially a staff directory. Using VS 2005, I've setup a basic grid view which connects to an object which connects via a data layer to a SQL database with Name, Surname, Email, Extension No and Department fields.
I have it working so that if a user enters a name and surname for example, it will return all records with either the name matching or surname matching input parameters. What I want to do is to set up a SQL query which is:
SELECT * FROM records WHERE (Name LIKE @Name) AND (Surname LIKE @Surname) AND (Email LIKE @Email) AND (Dept LIKE @Dept)
so that if the user only enters the first name and surname for example as above, it ONLY returns the record which matches the first name and surname and not all records with either/or. One way I've thought of to do this is to convert the empty fields to "Nothing" so that it fullfils the search parameter for the empty fields. If someone can explain how to do this, or can suggest a better way, I'd be grateful.
Cheers,
Tom

Hi,
I am quite new to SSIS (I was a DTS developer) and I have a specific requirement to validate all incoming data using regular expressions. For each row in my input file, all columns will need to be validated against an expression. We have approx 60 different input files (a combination of xml and text files) with column counts going from 10 up to 120.
Also each input file will contain a footer which will need to be validated for record counts.
I would like the solution to be as generic as possible as the requirements for each file are similar -the only difference being the column names and the expressions to check against. I would really rather not have a different data flow task for each input file type as there are so many.
Can anybody suggest the most efficient/reusable way to do this? What I was thinking of was this:
Split the input file into detail/footer
create a temporary table based on the input file type with CHECKconstraints (regular expressions) for each column
for each detail record load it into the temp table
redirect any failures to another destination e.g. sql error table
Any other ideas would be very helpfull
Many Thanks
Gaye

I am trying to import a file to a db table from a mainframe system. When I look at it on the PC has some special characters in it. They look like nulls and or tabs. When I try to define the fields in DTS, I only see up to the first special character.
I tried to write a quick VB program to strip them out, but when VB is reading the file they get stripped out before I see them in the program.
Any help would be greatly appreciated.

Background:
I am new to SSIS.
I have a data flow task within a For Each Loop Container.
Its reading a Demilited Flat File and inserting into a DB table.
The Flat File Source reads a specified folder and picks up all files with extension .txt
Question:
How can I record and save the file names the package picks up and loads it in ?
For eg:
If I have under C:Test folder
File1.txt
File2.txt
File3.txt
And the package picks up all the files above and loads them in, is it possible to read the file name its processing ?
I have a need to read these file names ( in this example File1,File2,File3 ) and store them in a DB table.
Appreciate your help.

Hi All,
Well, tha case here is simply that i have a (Suppliers.csv) as an Input.
When taking that file, I do some validation on it's rows (Data type validations, Mandatory Fielda validations..etc).
When some rows to do not meet the requirments i put in these validations , it is supposed to be directed to an (Errors) Table in my SQL DB.
I want to include the order of the invalid row in the input File (The row which did not pass from the pre-mentioned validations) within the (Errors) Table when i direct the invalid rows to it.
Any ideas ?

I am using the flat file connection manager. I read in a set of flat files and copy them into a staging database table. I want to ignore anything in the text file past column 266. I can't get this to work correctly. I can't define the last column to end at 266 and ignore the rest. I tried adding an extra column but that did not work either.

Hi,
I want to create a text file and write to text it by calling its assembly from Stored Procedure. Full Detail is given below
I write a code in class to create a text file and write text in it.
1) I creat a class in Visual Basic.Net 2005, whose code is given below:
Imports System
Imports System.IO
Imports Microsoft.VisualBasic
Imports System.Diagnostics
Public Class WLog
Public Shared Sub LogToTextFile(ByVal LogName As String, ByVal newMessage As String)
Dim w As StreamWriter = File.AppendText(LogName)
LogIt(newMessage, w)
w.Close()
End Sub
Public Shared Sub LogIt(ByVal logMessage As String, ByVal wr As StreamWriter)
wr.Write(ControlChars.CrLf & "Log Entry:")
wr.WriteLine("(0) {1}", DateTime.Now.ToLongTimeString(), DateTime.Now.ToLongDateString())
wr.WriteLine(" :")
wr.WriteLine(" :{0}", logMessage)
wr.WriteLine("---------------------------")
wr.Flush()
End Sub
Public Shared Sub LotToEventLog(ByVal errorMessage As String)
Dim log As System.Diagnostics.EventLog = New System.Diagnostics.EventLog
log.Source = "My Application"
log.WriteEntry(errorMessage)
End Sub
End Class
2) Make & register its assembly, in SQL Server 2005.
3)Create Stored Procedure as given below:
CREATE PROCEDURE dbo.SP_LogTextFile
(
@LogName nvarchar(255), @NewMessage nvarchar(255)
)
AS EXTERNAL NAME
[asmLog].[WriteLog.WLog].[LogToTextFile]
4) When i execute this stored procedure as
Execute SP_LogTextFile 'C:Test.txt','Message1'
5) Then i got the following error
Msg 6522, Level 16, State 1, Procedure SP_LogTextFile, Line 0
A .NET Framework error occurred during execution of user defined routine or aggregate 'SP_LogTextFile':
System.UnauthorizedAccessException: Access to the path 'C:Test.txt' is denied.

I am not sure if this has been asked before but I couldn't find any thread talking about this.
Let's say we have a parameter in the .sql input file called @Start_Date, how can we pass the value of a particular date, for example, "02-28-2007" to @Start_Date via SQLCMD? is it possible?
I'm trying to skip the need to write a simple windows application...if things can be achieved via dos command line, that will keep everything simple!
thanks! :)

Each day I receive a file with a different name. For example, the name is filename_mmddyyyy.txt where filename_ stays constant and mmddyyyy is the date of the file. The file is always in the same format.
I want to build an SSIS where I pass it this file name. I can write a script to generate the correct file name. How do I build the SSIS so it can accept the input parameter and find the correct file to process?
Thanks

Hey All,
Similar to a previous post (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=244646&SiteID=1), I am trying to import data into a SQL Table.
I am trying to program a small application that will import product data obtained through suppliers via CD-ROM. One supplier in particular uses Fixed width colums, and data looks like this:
Example of Data
0124015Apple Crate 32.12
0124016Bananna Box 12.56
0124017Mango Carton 15.98
0124018Seedless Watermelon 42.98
My Table would then have:
ProductID as int
Name as text
Cost as money
How would I go about extracting the data with an XML Format file? I am stumbling over how to tell it where to start picking up data for a specific column.
Is there any way that I could trim the Name column (i.e.: "Mango Carton " --> "Mango Carton")?
I don't know if it makes any difference, but I've been calling SQL from my code by doing this:
Code in C# Form
SqlConnection SqlConnection = new SqlConnection(global::SQLClients.Properties.Settings.Default.ClientPhonebookConnectionString);
SqlCommand cmd = new SqlCommand();
cmd.CommandType = CommandType.Text;
cmd.CommandText = "INSERT INTO PhonebookTable(Name, PhoneNumber) VALUES('" + txtName.Text.ToString() + "', '" + txtPhoneNumber.Text.ToString() + "')";
cmd.Connection = SqlConnection;
SqlConnection.Open();
cmd.ExecuteNonQuery();
SqlConnection.Close();
RefreshData();
I am running Visual Studio C# Express 2005 and SQL Server Express 2005.
Thanks for your time,
Hayden.

I am using the following useful article regarding exporting a multi-record file:
http://vsteamsystemcentral.com/cs21/blogs/steve_fibich/archive/2007/09/25/multi-record-formated-flat-file-with-ssis.aspx
I have created the 2 datasources, ordering each on a field commmon to both.
I have created the two derived columns headers and am now moving on to the merge.
It is failing with the following error:
"the input is not sorted"
And whilst I definitely have an order by on the query, when I look at the metadata between the datasource and the derived column, the Sort Key Position items displays "0" for all my fields, I was expecting the sort field to have a "1" in this column. What am I missing?
Any help would be most appreciated!

I have a delimited text file with 650+ columns. The sum of the column lengths of a single row, if fully populated, exceeds 30K bytes. The "killer" fields lengthwise are the "Description" fields. If they were removed from the input file, the remainig columns would occupy about 5000 bytes, which is within SQL max row length.Â
Can SSIS be used to created these two tables? (one without  description fields, the other with those field but arranged vertically in the table rows).
The fundamental issue is I can not import a single file row into a sql table because that row length could exceed the max byte count for a row.

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;
}
public const string Property_Task = "CustomErrorControl";
public const string Property_SourceConnection = "SourceConnection";
public void LoadFromXML(XmlElement node, IDTSInfoEvents infoEvents)
{
if (node.Name != Property_Task)
{
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)
{
infoEvents.FireError(0, "LoadFromXML", ex.Message, "", 0);
}
}
}
public void SaveToXML(XmlDocument doc, IDTSInfoEvents infoEvents)
{
try
{
// // Create Task Element
XmlElement taskElement = doc.CreateElement("", Property_Task, "");
doc.AppendChild(taskElement);
// // Save source FileConnection
XmlAttribute sourcefileAttribute = doc.CreateAttribute(Property_SourceConnection);
sourcefileAttribute.Value = _sourceConnectionId;
taskElement.Attributes.Append(sourcefileAttribute);
}
catch (Exception ex)
{
infoEvents.FireError(0, "SaveXML", ex.Message, "", 0);
}
}
In UI Class there is OK Click event.
private void btnOK_Click(object sender, EventArgs e)
{
try
{
_taskHost.Properties[CustomErrorControl.Property_SourceConnection].SetValue(_taskHost, propertyGrid1.Text);
btnOK.DialogResult = DialogResult.OK;
}
catch (Exception ex)
{
Console.WriteLine(ex);
}

Hi,
I am planning to develop a single package that will download files from ftp server, move the files to internal file server and upload it in the database. But I want to run this package for multiple ftp file providers. For each provider the ftp server might be different and the transformation to upload the files into a database table might be different.
So can I create a single package and then multiple configuration files (xml), which will contain the details fo the ftp file providers and then pass the xml file as a parameter while executing the package. The reason being that the timings of fetching the files is different for each ftp file provider and hence cannot be combined into one.
Is this possible?
Thanks for your help.

Hi All,
I receive the input file with some 100 columns and some 20k+ rows and I want to check the incoming input row is existed in the database or not based on 2 key columns. If the row is existed then I need to check all the columns (nearly 100 columns) values in input and the database are equal or not. If both are equal I need to treat them seperately if not there is a seperate logic. How Can I do that check for each row and for each column?
Basically the algorithm is like this, if the input file row is not existed in the database then treat that as new row else if the input row is existed in the database then check all the columns are equal or not. If all the columns are equal then treat that as existing row and do nothing else if some columns are not equal then treat this row seperately.
I found some thing to achieve the above thing.
1. Take the input row and check in the database.
2. If the row is not found in the database then treat it as new row.
3. If row is found in the database then
a) Take the source row and prepare a concatenated string for all the columns
b) Take the database row and prepare a concatenated string for all the columns
c) Find out the hash code for the 2 strings and then compare hash codes for equal.
The disadvantage of this is running a loop 2*m*n times where m is the number of rows and n is the number of columns. It should be done 2 times for input file row and database row.
Can anybody suggest a good method to do this?
What does the function "GetHashCode" for InputBuffer in method "Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)" will do?
Will it generates hash code based on all the columns values?
Pls clarify.
Regards
Venkat.

I am trying to prove I can use SSIS to connect to a web service. The WS I am trying to connect to was developed by a vendor and covered by a NDA, but I was able to reproduce the issue with a public WS.
Here are the steps to reproduce the issue:
In the Web Services Connection Manager, I entered http://office.microsoft.com/Research/Providers/MoneyCentral.asmx?wsdl in the URL window. I am able to successfully "test" the connection
I pasted the above link into IE and saved the resulting XML as a .wsdl file on my local machine. In the Web Services Task Editor, General Tab, I specify the path to the .wsdl file and click on "Download WSDL" button. No Issues
When I click on "Input" and select "MoneyCentralRemote" from the drop-down for Service, I receive an error message saying "This version of the Web Services Description Language (WSDL) is not supported"
So the questions are:
Did I perform the above steps correctly?
What WSDL versions are supported in SSIS?
How can I tell what WSDL version was used to create the .wsdl I am trying to access?
If the WSDL is an unsupported version, is there a work-around to fix the issue?
