how the hell you allocate a null value for a smalldatetime sql field?
Now, I'm putting a false date because of I'm stuck with this f.. and then I do an update:
.Parameters("@FecEnajenacion").Value = "1999-01-01"
error:
.Parameters("@FecEnajenacion").Value = vbNull
.Parameters("@FecEnajenacion").Value = Null
.Parameters("@FecEnajenacion").Value = SqlDbType.???????
In a Data Flow, I have the necessity to use a SSIS variable of type €œObject€? inside Script Component and assign to it the content of 'n' variables of string type.
On exiting from the script the variable of type object should contain something like in the following lines:
AAAAAAAAAAAAAAAAAAAAAAAAAAAAA
BBBBBBBBBBBBBBBBBBBBBBBBBBBBB
CCCCCCCCCCCCCCCCCCCCCCCCCCCCC
DDDDDDDDDDDDDDDDDDDDDDDDDDDDD
€¦€¦€¦€¦€¦€¦€¦.
€¦€¦€¦€¦€¦€¦€¦.
On exiting from the data flow I will use the variable of type Object in a Script Task, by reading each element in a cyclic fashion.
Is there anyone who have experienced something like this? Could anyone provide any example of that?
Thanks in advance!
From a text file I'm importing date values by a variable.
dFecha = Left(Row.Column21, 4) & "/" & Mid(Row.Column21, 5, 2) & "/" & Right(Row.Column21, 2)
After that I've got values as "0000-00-00" and obviously sql (at target smalldatetime) doesn't support them. How do I for to solve?
If IsDate(dFecha) Then
.Parameters("@FecEnajenacion").Value = dFecha
Else
.Parameters("@FecEnajenacion").Value = vbNull
End If
TIA
Hi all,
I have a class that utilizes the ThreadPool together with a ManualResetEvent to queue up work items (in this case, FTP downloads) and then waits until all work items have completed before proceeding.
I then use this class inside a Script Component. However, I am getting a "remote procedure call failed" every single time the FTP component starts a download. This same class works perfectly in a WinForm app that I created as a test harness. Also, the synchronized version of the FTP download component works perfectly well from the Script Task -- it's only when I "wrap" the synchronous version in a threaded version that it fails.
Also, when the "remote procedure call failed" exception occurs, sqldumper.exe runs for a split second and creates a minidump. I, unfortunately, cannot inspect the dump because VS2k5 throws a native error when I try to "debug" the dump.
Is it possible to utilize multithreaded code inside SSIS? I noticed that SQL Server prohibits the use of threading as part of its hosting requirements (http://msdn2.microsoft.com/en-us/library/ms172338.aspx) but I'm not sure how that would impact (if at all) the SSIS host.
Thanks,

No idea where this bug crept in from. Have been using SSIS for 1.5 years now without hitting this problem.
I had a script component opening an XML document and parsing it using XPATH. I added some code that uses StreamReader / Streamwriter (closing one stream before starting the other). The code works without issue in my C# app.
And it ran without issue 2-3 times in SSIS. Then suddenly after running my package again, the script component says it completes successfully, yet nothing happens. I set a breakpoint on the first line of code - it never hits it. I add a msgbox as the first line of code - and it never displays.
I then close my package / exit out of ssis ... and then re-open it. When i open my script component, all of my code is GONE. All references that I added are gone.
I tried adding the streamreader/writer process to a dll I created from my c# app ... and added the DLL to the package -- same result.
I can reproduce this on 2 different computers.
Anyone experience this problem ? Any idea how to stop it ? Or debug it ?
Here is a slimmed down code sample of what causes the error :
Public Class ScriptMain
Public Sub Main()
Try
Dim xmlDoc As New XmlDocument
xmlDoc.Load("c:ulkasync_86281519_20070628045850225_4.xml")
MsgBox("xmlLoaded") --this doesn't display once the package starts "acting up"
Catch ex As Exception
MsgBox(ex.Message)
UpdateXML("c:ulkasync_86281519_20070628045850225_4.xml", ex.Message)
End Try
Dts.TaskResult = Dts.Results.Success
End Sub
Private Sub UpdateXML(ByVal fileName As String, ByVal message As String)
Try
Dim invalidChar As String = message.Trim().Substring(message.Trim().IndexOf("0x"), 4)
Dim rd As StreamReader = New StreamReader(fileName)
Dim xml As String = rd.ReadToEnd()
Xml = Xml.Replace(invalidChar, String.Empty)
xml = xml.Replace("", String.Empty)
xml = xml.Replace("<![CDATA[<![CDATA[", "<![CDATA[")
xml = xml.Replace("]]>]]>", "]]>")
MsgBox("replaced")
rd.Close()
Dim wr As StreamWriter = New StreamWriter(fileName)
wr.Write(xml)
wr.Close()
Dim xdoc As XmlDocument = New XmlDocument()
xdoc.Load(fileName)
Catch ex As Exception
UpdateXML(fileName, ex.Message)
End Try
End Sub
End Class

Hello everyone,
I am using DTS to transform data from foxpro.when it meets the date of NULL,it fails and says"Insert Error , column 4( 'Coloumn_name ',DBTYPE_DBTIMESTAMP), Status 6 data overflow ".
And then i try to open the DTS Transform Data task and do a preview of the data from the 'Source' side.The Null values are treated as "1899-12-30".
After reading something ,i try to write an ActiveX scripting Task to solve this problem using the function of "IsDate()",but it fails with exceptions.
Now I don't know what to do.could anyone give me some suggestion?Anything will be appreciated!ThankX in advance!
hi
how can we insert null into a small datetime field (from client application VB)
Hello - I have a column in a table (SQL 2005 EE) with a Data Type of smalldatetime and a Default Value of getdate(). When I insert a record from my webpage the new record contains the correct date via getdate(). However if I update the record from my webpage the date of the record then becomes NULL. Is this normal? Is there anything I can do about this from sql server? I am inserting/updating via an formview and ODS, using standard insert/update methods.
Cheers

Hi,
I'm experiencing a problem I think I should not in my COM+ application. I will describe the setup first and then will expose the problem.
It's a simple COM+ application (dll). Inside it, there's a method to save an object A. Object A is persisted in a table in SQL Server 2000 that uses an identity field for the primary key. What this method does is the following:
1) Insert the record for Object A via ADO
2) Retrieve the Id for the object using SCOPE_IDENTITY via ADO and set it on the object
3) Execute an UPDATE statement based on a certain condition via ADO (this UPDATE statement will fire a trigger, however the trigger will not do anything since the record does not answer the criteria for the trigger)
4) Insert a record for another Object A via ADO
5) Retrieve the Id for the object using SCOPE_IDENTITY via ADO and set it on the object
When I get to step (5), an error is raised because SCOPE_IDENTITY returns NULL. This is as if it was returning the Identity value for the trigger that did not cause any INSERT on the UPDATE statement in (3). All the steps are performed using a single connection.
The trigger will duplicate the updated record in another table if a certain flag is set, so in my case, it was not set yet.
It's just weird that this would happen. If I delete the trigger, everything works fine. @@IDENTITY gives me the same problem. It's really as if the trigger was taking over or something and unless I put something between the two steps I get this error. There's one thing though. In step (3), I was using the adCmdText flag for the ADO statement. If I use adExecuteNoRecords it works fine. However I don't understand why it would be this way, I'm trying to understand why it's not working to begin with, even though the sequence of the steps performed should.
Any idea why this would happen?
Thanks,
Greg
Within a data flow I have a script component that I want to perform some data calls from. I want to execute SQL commands to connections already defined in the package's connection manager.
Is there a way to set my script's connection variable to the connection manager connection? Or, can I use the connection manager connections directly from within the script?

I have a requirement to access a lookup table from within an SSIS Transform Script Component
The aim is to eliminate error characters from within the firstname, lastname, address etc. fields by doing a lookup of an ASCII code reference table and making an InStr() type comparison.
I cannot find a way of opening the reference data set from withing the transform.

Hi all,
I use a "Exec DTS 2000" task.
I have a variable user::MYVAR in my SSIS package, wich value is "PARENT".
I pass this variable as an outer variable to my dts 2000 package, wich receive it correctly, and then update it to "UPDATED".
After this task finishes, when I come back to SSIS, MYVAR is still at "PARENT".
Is it possible to see the update from the parent package ?
Thanks
Hi,
Can we include a Send Mail Task inside a transaction?
We intend to callback a sent email in case there is an error in the subsequent task, if it is possible.
Thanks and Regards,
B@ns.
We are designing an ETL solution for a BI project using SSIS.
We need to load a dimension table from a source DB into the DW; inside the DW there are two tables for each source dimension table: a current dimension table and a storical dimension table.
The source table includes technical columns that indicate if each record was processed correctly by ETL procedures.
Each row in the source table can be a new record, or an exisisting one. If it's a new record, a corresponding new record should be inserted into the current dimension table of the DW; if it's an exisisting one, a new record should be inserted in the storical dimension table and the existing record in the current dimension table should be updated.
Furthermore for each record we need to update the source table with an error code. If the record was processed with succes the code is zero, otherwise it contains an error code.
I try to use a single data flow task, using the 'ole db command trasformation' task for managing update and 'ole db destination' task for managing insert.
The problem is that some insert and update should be executed inside a single transaction, for each record; for example if the source contains a new record I should insert the record in the current dimension table and update the source record with error code zero if every think goes fine.
There is some way to group task in the data flow pane in a single transaction ?
There is a better way to do that ?

I've been looking around but haven't yet found the syntax for usage of global variables in an SQL Task.
I've set the global variable Id (see code below):
if (select field from table where id = @[User::id]) is null
select top 1 1 as response from table
else select top 1 0 as response from table
My objective with it is to set another global variable (@isNull). Supposably, when the selection returns null, I should set the variable to null, I did it by using the selections and mapping the response to that variable (is ther a better way to do so?).
When I try to execute this, it says the variable has not been defined.
Here is the error:
Error: Must declare the variable '@'.
I've also tryed it withou the brackets and the User:: thing in the beggining, (@id directly) and here is the response:
Error: Must declare the variable '@id'.
How should I access the global variables in the SQL code?
(BTW, I've checked the field in execution time and it is set to 23, the correct Id, so the block that preceedes this one is working properly)
Thanks,
Hi, I'm trying to loop thru a table and insert records into another table in ssis. So far I have been able to get the data using a execute sql task set up to store the full result set into a variable called data. I then drug a foreach loop container out and selected the foreach ADO enumerator and used my variable data as the ADO object source variable. I then set up a new variable under variable mappings with index 0 to get the collection values. How do I take that variable and update another table using another sql task inside the foreach loop container? Is this possible?
thanks,
I'm reading over this thread: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1884062&SiteID=1
and I'm kinda lost as to what to do to strip out the dtd from an XML file I am downloading. I do NOT know XSLT and for that reason, I can't follow his logic.
My SSIS package downloads my XML file just fine, now I need to do a strip of the DTD line in my XML Task.
The person who provided the solution in the above post said to do this...
Code Snippet
Operation Type: XSLT
Source Type: Variable
Source: Variable's name containing the xml text
Save Operation Result: True
DestinationType: Variable
OverwriteDestination: True
Destination: Variable's name which is to contain the original xml minus the DTD.
SecondOperandType: Variable
That stuff I understood. I'll replace variables with my files because they are stored that way, but from what I can tell, that's not my problem.
The stuff he says below this comment is going over my head like a ton of bricks. I can't figure out how to do it.
This is the kind of line of my XML that I want to strip out.
https://www.myaddy.com/pbdr.dtd"[]>
and then he said this...
Code Snippet
Since XSL doesn't know about DTDs, telling it to copy everything strips out DTDs. Then use the Variable specified in the Xml task's SecondOperand as the Source data for the xml source.
Code Snippet
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<xsl:copy-of select="." />
</< FONT>xsl:template>
</< FONT>xsl:stylesheet>
A note on how to paste a multi-line xml document into a Integration Services String variable:
Integration Services String variables textboxes are not multi-line, in the Windows sense of a line (CR+LF),
So, in order to paste multi-line text (which xml docs almost always are), save a temporary copy with a unix line ending.
That is, create an xml file in visual studio, and paste your sample original xml in there. Go to File/Advanced Save options, and save the xml with the the settings of Encoding: Unicode (utf-8 without signature) - CodePage 65001, and most importantly, set the Line endings dropdown to "Unix (LF)".
After selecting "OK", copy and paste the text from Visual Studio's xml file editor into the IS variable, and you'll note all the xml data appears.
So can anyone walk me through a dummies version of what he is suggesting to do?
Thanks,
Keith
Hi,
I'm having trouble with a Script Component in a data flow task. I have code that does a SqlCommand.ExecuteReader() call that throws an 'Object reference not set to an instance of an object' error. Thing is, the SqlCommand.ExecuteReader() call is already inside a Try..Catch block. Essentially I have two questions regarding this error:
a) Why doesn't my Catch block catch the exception?
b) I've made sure that my SqlCommand object and the SqlConnection property that it uses are properly instantiated, and the query is correct. Any ideas on why it is throwing that exception?
Hope someone could help.
Hi,
I have tables like the one below for my Stage and dimension tables:
Stage Table
accountid
name
address
Dimension Table
accountkey ---- surrogate key (DW key)
accountid ---- business key (transaction's primary key)
name
address
I used slowly changing dimension to detect the changes for the records inside my Dimension table. But I had a problem when a new record exists in the stage table. The accountkey is set as the primary key and it gets its value from a different table which stores the last account key that was created. I cannot load all the changes unless i have a business key. Is there a way that i can get the "last key" from a different table in the data flow area and then supply it together with the other fields in the new output branch of the slowly changing dimension?

Hi,
I am using an XML task for validating the XML data against the Schema XSD. I have more XML Files with same the schema. I have to used a for loop container which has an XML task for validate XML. The loop container gets the XML File into variables name "XMLFileName" which the loop current file, in turn, used by XML Task for validation.
XML task is configured in the option "Validate". I have provided the XML Data in variable name "XMLFileName" also get the name from the loop container and XSD file content File Connection. XML Task stored the result in the another variable name "OKFormat". FailOnValidationFail property set to false.
It had the error when I run the package, the error msg as below:
Error: 0xC002F304 at XML Task, XML Task: An error occurred with the following error message: "Data at the root level is invalid. Line 1, position 1.".
Error: 0xC002928F at XML Task, XML Task: Property "New Source" has no source Xml text; Xml Text is either invalid, null or empty string.
Task failed: XML Task
After that, I had to change the source type from Variable to File Connection, and had to test fixed to some xml file it had ok for validate the XML file againt XSD.
I don't know this is the wrong setting or bug of SSIS, anyone can guide me through.
Hi
Is there any task which helps up to update data inside the data flow task or any method to do the same.....
I have a timestamp column and a username column with default values of getdate and system user in my table and they are defined as not null.
even though i donot use these columns in scd type 2 in wizard
if the columns are not null the scd deosnot work and If the columns are defined null they work
Can anyone please explain or help me with what might be the problem associated with this
I am looping through xml files and validating them with the XML Task. On sucess I want to perform task 2, on failure I want to perform task 3. When one file fails to validate all subsequent tasks fail.
I have also tried putting the result in a variable instead of using the success constraint. I get the same result, the variable keeps the failed value after the first file fails. Any advise is greatly appreciated.
in a SSIS 2012 pkg, I'm trying to specify a SELECT TOP ? myColumn FROM myTable inside an Execute SQL task, but unsuccessfully.Is it possible to parameterize the TOP clause?

I've been using SSIS for a few months now, and am comfortable with most of the tools, except for the script task and script component. I don't remember any VB code from college - is that the best place to start in order to fully understand how to code the script task and component? I need to understand the situations where/when I would use scripting, why, etc. I've used a few examples on the internet to do some simple tasks, but need to understand the code I'm implementing. Any direction would be much appreciated.
How to debug a Script Component task?
For instance, I€™ve got a Input0_ProcessInputRow procedure and I€™d like to see what happen when compiler reach this line:
dFecha = Left(Row.Column19, 4) & "-" & Mid(Row.Column19, 5, 2) & "-" & Right(Row.Column19, 2)
I€™ve put a toogle breakpoint there and then saved but when I run the package to ignore at all.
This topic has been already discussed in these newsgrups but I still have doubts.
Thanks a lot for any advice or clarification
