Mapping Of An Xml Column To Variable
Aug 23, 2006
I have a For Each Loop that iterates over a recordset stored in a variable. One of the columns in the recordset is type xml and I want to map it to a variable using Variable Mappings of the For Each Loop container. I am getting this error:
Error: 0xC001C012 at FELC Loop thru report defs: ForEach Variable Mapping number 4 to variable "User::Parameters_xml" cannot be applied.
I have tried changing the type of the Parameters_xml variable to Object and String, but I get the same error. Any ideas?

I'm new to SSIS, but have been programming in SQL and ASP.Net for several years. In Visual Studio 2005 Team Edition I've created an SSIS that imports data from a flat file into the database. The original process worked, but did not check the creation date of the import file. I've been asked to add logic that will check that date and verify that it's more recent than a value stored in the database before the import process executes.
Here are the task steps.
[Execute SQL Task] - Run a stored procedure that checks to see if the import is running. If so, stop execution. Otherwise, proceed to the next step.
[Execute SQL Task] - Log an entry to a table indicating that the import has started.
[Script Task] - Get the create date for the current flat file via the reference provided in the file connection manager. Assign that date to a global value (FileCreateDate) and pass it to the next step. This works.
[Execute SQL Task] - Compare this file date with the last file create date in the database. This is where the process breaks. This step depends on 2 variables defined at a global level. The first is FileCreateDate, which gets set in step 3. The second is a global variable named IsNewFile. That variable needs to be set in this step based on what the stored procedure this step calls finds out on the database. Precedence constraints direct behavior to the next proper node according to the TRUE/FALSE setting of IsNewFile.
If IsNewFile is FALSE, direct the process to a step that enters a log entry to a table and conclude execution of the SSIS.
If IsNewFile is TRUE, proceed with the import. There are 5 other subsequent steps that follow this decision, but since those work they are not relevant to this post.
Here is the stored procedure that Step 4 is calling. You can see that I experimented with using and not using the OUTPUT option. I really don't care if it returns the value as an OUTPUT or as a field in a recordset. All I care about is getting that value back from the stored procedure so this node in the decision tree can point the flow in the correct direction.
CREATE PROCEDURE [dbo].[p_CheckImportFileCreateDate]
/*
The SSIS package passes the FileCreateDate parameter to this procedure, which then compares that parameter with the date saved in tbl_ImportFileCreateDate.
If the date is newer (or if there is no date), it updates the field in that table and returns a TRUE IsNewFile bit value in a recordset.
Otherwise it returns a FALSE value in the IsNewFile column.
Example:
exec p_CheckImportFileCreateDate 'GL Account Import', '2/27/2008 9:24 AM', 0
*/
@ProcessName varchar(50)
, @FileCreateDate datetime
, @IsNewFile bit OUTPUT
AS
SET NOCOUNT ON
--DECLARE @IsNewFile bit
DECLARE @CreateDateInTable datetime
SELECT @CreateDateInTable = FileCreateDate FROM tbl_ImportFileCreateDate WHERE ProcessName = @ProcessName
IF EXISTS (SELECT ProcessName FROM tbl_ImportFileCreateDate WHERE ProcessName = @ProcessName)
BEGIN
-- The process exists in tbl_ImportFileCreateDate. Compare the create dates.
IF (@FileCreateDate > @CreateDateInTable)
BEGIN
-- This is a newer file date. Update the table and set @IsNewFile to TRUE.
UPDATE tbl_ImportFileCreateDate
SET FileCreateDate = @FileCreateDate
WHERE ProcessName = @ProcessName
SET @IsNewFile = 1
END
ELSE
BEGIN
-- The file date is the same or older.
SET @IsNewFile = 0
END
END
ELSE
BEGIN
-- This is a new process for tbl_ImportFileCreateDate. Add a record to that table and set @IsNewFile to TRUE.
INSERT INTO tbl_ImportFileCreateDate (ProcessName, FileCreateDate)
VALUES (@ProcessName, @FileCreateDate)
SET @IsNewFile = 1
END
SELECT @IsNewFile
The relevant Global Variables in the package are defined as follows:
Name : Scope : Date Type : Value
FileCreateDate : (Package Name) : DateType : 1/1/2000
IsNewFile : (Package Name) : Boolean : False
Setting the properties in the "Execute SQL Task Editor" has been the difficult part of this. Here are the settings.
General
Name = Compare Last File Create Date
Description = Compares the create date of the current file with a value in tbl_ImportFileCreateDate.
TimeOut = 0
CodePage = 1252
ResultSet = None
ConnectionType = OLE DB
Connection = MyServerDataBase
SQLSourceType = Direct input
IsQueryStoredProcedure = False
BypassPrepare = True
I tried several SQL statements, suspecting it's a syntax issue. All of these failed, but with different error messages. These are the 2 most recent attempts based on posts I was able to locate.
SQLStatement = exec ? = dbo.p_CheckImportFileCreateDate 'GL Account Import', ?, ? output
SQLStatement = exec p_CheckImportFileCreateDate 'GL Account Import', ?, ? output
Parameter Mapping
Variable Name = User::FileCreateDate, Direction = Input, DataType = DATE, Parameter Name = 0, Parameter Size = -1
Variable Name = User::IsNewFile, Direction = Output, DataType = BYTE, Parameter Name = 1, Parameter Size = -1
Result Set is empty.
Expressions is empty.
When I run this in debug mode with this SQL statement ...
exec ? = dbo.p_CheckImportFileCreateDate 'GL Account Import', ?, ? output
... the following error message appears.
SSIS package "MyPackage.dtsx" starting.
Information: 0x4004300A at Import data from flat file to tbl_GLImport, DTS.Pipeline: Validation phase is beginning.

This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the errors.
SSIS package "MyPackage.dtsx" finished: Failure.
When the above is run tbl_ImportFileCreateDate does not get updated, so it's failing at some point when calling the procedure.
When I run this in debug mode with this SQL statement ...
exec p_CheckImportFileCreateDate 'GL Account Import', ?, ? output
... the tbl_ImportFileCreateDate table gets updated. So I know that data piece is working, but then it fails with the following message.

SSIS package "MyPackage.dtsx" finished: Failure.
The IsNewFile global variable is scoped at the package level and has a Boolean data type, and the Output parameter in the stored procedure is defined as a Bit. So what gives?
The "Possible Failure Reasons" message is so generic that it's been useless to me. And I've been unable to find any examples online that explain how to do what I'm attempting. This would seem to be a very common task. My suspicion is that one or more of the settings in that Execute SQL Task node is bad. Or that there is some cryptic, undocumented reason that this is failing.
Thanks for your help.

I can€™t figure out how to map xml data stored in a table to a variable in integration service.
For example:
I would like to use a €œfor each loop container€? to iterate through a row set selected from database. Each row has three columns, an integer, a string and an xml data. In the variable mappings, I can map the integer column and the string column to a variable with type of int and a variable with type of string. But I am having trouble to map the xml data column to any variable. I tried using either a string variable or object. It always reports error like €œvariable mapping number X to variable XXX can€™t apply€?.
Any help?

Hi there,
I am working on SSIS package that gets data from SQL 2005 Database and writes that to a flat file. But I need to write the count of records as part of the header.
Here is what i am trying:
The OLE DB Source is calling a stored procedure and returning two things i.e. a resultset and an output parameter. The data access mode is SQL Command.
Code SnippetEXEC [Get_logins] ?, ?, ? OUTPUT
In the Set Query Parameters dialogbox, all the three patameters are mapped to three different user variables.
What is happening is that the user variable that is mapped to output parameter is never updated. The header property expression is written as follows
Code SnippetRIGHT("0000000000" + (DT_STR, 10, 1252)@LoginCount, 10)
I tried to watch the variable in watch window but to no avail. Any guidance if it is bug or I am missing some thing? Any thoughts, how can I accomplish this? I have also tried adding Row Count Transformation but its variable has the same behaviour. If I set the value of @LoginCount variable to some value, this initially set value is successfully written to the file header.
Thanks

I'm just getting started with SSIS and have a couple basic questions. I have a Foreach Loop that iterates over a collection of database names. The collection must include only database names that match a substring. I haven't found a way to filter the SMO Enumerator collection so, instead, I feed the resultset of an Execute SQL Task into the Foreach Variable Enumerator.
Of course this variable (oDBnames) is object type so in Foreach Variable Mapping a string variable (sDBname) is mapped to the only value in the collection (database name). Now sDBname should be available for an Execute SQL Task inside the container. But I keep getting the following errors:
Error: 0xC001F009 at Package: The type of the value being assigned to variable "User::sDBname" differs from the current variable type. Variables may not change type during execution. Variable types are strict, except for variables of type Object.
Error: 0xC001C012 at Foreach Loop Container: ForEach Variable Mapping number 1 to variable "User::sDBname" cannot be applied.
Can someone explain what is going on and how to correct this? I haven't found an answer in BOL or MSDN yet. Thanks.
Another beginner question: The results/messages from a query run in Management Studio are displayed in the results/messages panes. But how would you save and view query output when using the Execute SQL Task? Seems like I should be able to dump Full result set into an object variable and display that, but everything I try raises an error ...

Hi:
I am trying to loop through 4 files in a folder and read the names of those files through the For each loop container task. I have 4 readme files (readme1.txt thru readme4.txt) in a folder called C:SSIS.
I have added a for each Loop container and a script task to my package. In the Variable Mapping page I have named the Variable and configured the index to be 0. The problem is when I execute the package the file name that is read is always readme1.txt. I want all the file names to be read under the folder ( in other words configure the index to be 0 thru 4). How do I configure the index so that it can read all the files?.
The following is the code I have in my script task:
Public Sub Main()
Dim variables As Variables
If Dts.Variables.Contains("FileName") = True Then
Dts.VariableDispenser.LockOneforRead("FileName", variables)
End if
Msgbox ("Retrieved the File " & CStr(variables("FileName").Value))
Dts.TaskResult=Dts.Results.Success
End Sub
When I execute the package with the above code, I always see a message box popping up and saying Retrived File Readme1.txt.
I want the msgbox to pop up and say
Retrieved Readme1.txt
Retrieved Readme2.txt
Retrieved Readme3.txt and so forth...
Any help on achieving this is appreciated.
Thanks

Hi all,
I'm working with Execute SQL task. Connection type: OLE DB. With the following settings, the task works fine:
Parameter mapping:
Code Snippet
Variable Name Direction Data type Parameter Name
User::InputFile Input NVARCHAR 0
User::DesiredOutput Input NVARCHAR 1
SQLStatement:
Code Snippet
exec [spu_CreateOutput] ?, ?
However, I want to put in some conditions so I modified the task as:
Parameter mapping:
Code Snippet
Variable Name Direction Data type Parameter Name
User::OutputFile Input NVARCHAR 0
User::InputFile Input NVARCHAR 1
User::DesiredOutput Input NVARCHAR 2
SQLStatement:
Code Snippet
if(? <> 'NotUsed')
Begin
exec [spu_CreateOutput] ?, ?
End
But the modification doesn't work. The following message was thrown:
Error: 0xC002F210 at CREATE OUTPUT, Execute SQL Task: Executing the query "if(? <> 'NotUsed')
Begin
exec [spu_CreateOutput] ?, ?
End
" failed with the following error: "Syntax error, permission violation, or other nonspecific error". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
Task failed: CREATE OUTPUT
Can anyone tell me what I have been wrong with it? It seems that parameter mapping can only apply for a single select statement/function/procedure call :-?
Thank you,

Hi Guys,here is my story.
I have a table with values stored in it and the Code Column contains sets of values that need to be mapped to a single value.For example i want the values ALMW,ARBAC to map to AL ARB and the values ARBIT,ARBOP,ARBSC to map to CU ARB and A1JAN,A1FEB,A1MAR,A1APR,A1MAY,A1JUN should map to AL AVG.
The values under Code are already in a database table and the ones under New Code are the new mappings for the values under code and are not in the database.
This table is referenced by other tables for the Code and i want those references to be done to the New Code instead.How do i modify the existing table or design a new table to preserve the current Codes and also map them to the new Code.
Code New Code
ALMW AL ARB
ARBAC
ARBIT CU ARB
ARBOP
ARBSC
A1JAN AL AVG
A1FEB
A1MAR
A1APR
A1MAY
A1JUN

Hi everyone,
So I have to export from a SQL 2005 table to a dBaseIV table using SSIS. Easy enough, however the catch is that the tables being exported will vary. I can send variables to the the package calling the sql table name and creating the DBF file with the same columns on the fly.
The problem is mapping the columns. From what I've been reading there is no way to alter the mapping in a package at runtime. I was hoping that there would be some sort of auto mapping setting that would match on the field names but I guess not. Anybody run in to this issue and have a work around? Thanks in advance....

Hey all! I have a bunch of questions, but let's start with this one:
Incoming from my flat file, I have two columns:
employee_id
dept_id
These indicate who did the work, and for which department (people can work for more than one department). In my destination table, I have the following two columns:
employee_id_sales
employee_id_wrhs
I want to map the employee id either to employee_id_sales or employee_id_wrhs, depending on the dept_id from the flat file.
How do I specify conditional column mapping?
I'm really new to SSIS, so I might be missing something obvious.
Thanks!

I am developing a transformation component and I'd like the gui to feature one of the mapping controls that are used for mapping input columns to, for example, SQL Server database columns in the OLE Database Destintation component, among others. I cannot for the life of me discover what the control is called or even whether it is available for general use. Can anyone help me out? Sorry if this is OT but it seemed like the people here would be the most likely to know immediatelly what I was on about.

Hello,
I am trying to understand the concept of left joins. I have the following query and am not sure about the left joins.
I am familiar with joins but the left join below is a little confusing.Below it seems like a third table is involved. Is this because there is no column to map to in the from table? Also, since tables sl and sc are mapped based on the SecurityID column and sl and ex do not have any common columns, table sc is mapped to ex using the left join? Which table's data will be returned based on the left join?
I checked the column type for the Exchange column(ex.LSECode) and it appears varchar(3).
SELECT SecurityID = sl.SecurityID
, Security = RTRIM(sec.Name) + ' - ' + RTRIM(sec.Description)
, Ticker = ISNULL(ids.RIC, ids.Ticker)
, Sedol = ids.Sedol
, ISIN = ids.ISIN
, Exchange = ex.LSECode
, Country = cty.iso_code
FROM #SecList sl
JOIN SecurityClassification sc
ON sl.SecurityID = sc.securityId
AND sc.source = 99
LEFT JOIN exchange_table ex
ON sc.ExchangeID = ex.exchange
Thanks in advance!!!

Does anyone know how to get destination coulmns to show up in the advanced editor for a custom component? I have a custom flat file destination component that builds the output based on a specific layout. It works as long as the upstream column names match my output names. What I want is to allow non-matching columns to be mapped by the user as they can in a stock flat file destination. The closest that I have been able to come is to get the "column mappings" tab to show up and populate the "Available Input Columns" by setting ExternalmetadataColumnCollection.IsUsed to true on the input. The problem is that the "Available destination columns" box is always empty. I have tried the IsUsed property on the output and pretty much every other property that I could find. On the Input and Output properties all of my columns show up under the output as both External and Output columns. Is there a separate collection for "destination" columns that I can't find? It's getting a little frustrating, is this something that can be done or do I have to write a custom UI to make it happen?
Thanks!

What is the best way to do this in SSIS?
If I have to use the conditional split then do I have to copy my complete mappings, exact change this one column?
Thank for the help this mapping will take me a long time!

Hi,
Is there a way to accomplish one- many or many -one or many - many column mappings in the SSIS data flow task or using any other tasks. We were able to do this in DTS Transform data task. Also is it possible to edit the mapping like:

I was using the code in this thread (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1371094&SiteID=1) to create a console application which can build the SSIS package dynamically and run the package.
If the source column and destination column names are of different cases then the application was failing during the mapping. So I modified the for each loop like below. Still this is not a fool proof method, this will work as long as all characters in the column names are upper or lower.
for eg., Source column = empl_id, Destination column = EMPL_ID, in this case the below code will work. if the source column or destination column is Empl_Id, then the below mapping will fail.
Code Block
foreach (IDTSVirtualInputColumn90 vColumn in vInput.VirtualInputColumnCollection)
{
IDTSInputColumn90 vCol = destnDesignTime.SetUsageType(input.ID, vInput, vColumn.LineageID, DTSUsageType.UT_READWRITE);
try
{
destnDesignTime.MapInputColumn(input.ID, vCol.ID, input.ExternalMetadataColumnCollection[vColumn.Name.ToLower()].ID);
}
catch
{
destnDesignTime.MapInputColumn(input.ID, vCol.ID, input.ExternalMetadataColumnCollection[vColumn.Name.ToUpper()].ID);
}
}
So how can I map the columns irrespective of the cases?

Hi Friends,
I have a small problem in parameter mapping for Execute SQL Task.
I am using a delete statement with 2 conditions.
Followed by another Execute SQL Task which contains commit statement.
delete from tname where c1 = ? and c2 =?
where c1 is number(4) datatype and c2 is of varchar2(20) datatype in oracle.
The connection manager i am using is ORacle OLE DB provider.
I am passing 2 global variables i.e g_v1 of Int32 and g_v2 of String Type.
In the parameter mapping of the Executing SQL task, i am mapping these 2 variables for
c1 and c2 and changed the datatypes inside parameter mapping as Numeric for c1 and Varchar for c2.
I also set the property as ByPassPrepare = True.
When i am executing the package i getting INVALID NUMBER ERROR.
i believe the SSIS is unable to perform the implict datatype converison.
For the next run, i changed the g_v1 varible datatype to Double and also i changed the parameter mapping for c1 as Doble datatype.
This time it is working fine. I can see the Green signal for the 2 SQL Tasks.
But when i connected to Oracle check the count in the table, the data is not getting deleted.
Also,
I set the property RetainSameConnection = TRUE for oracle connection manager.
I am not able to trace this logical error.
The same is working fine in my local machine.
But i am facing the problem when i deployed the same on the client machine.
Is there any problem with parameter mapping?
What should be equialent Datatype for Oracle NUMBER datatype that should be used inside the SSIS package while declaring the global variable and
inside the parameter mapping.
Any thoughts!

Hi,
If you use a component that has a column mapping tab (most do) then you know that the component will try and map input and output columns automatically by name.
Is there a way to disable this feature when writing your own custom components? There is already a manual way to do this: rightmouse in the mappings tab of a component and chosen "Map Items By Matching Names". I find it is less helpful to auto-map initially because the designer tends to not think about the mappings.
A way of turning of auto-mapping in existing components would be cool too!
Cheers,
Martin

Hello everyone,
I am having a little problem with a simple package and I do not know if this is a known issue or that I am missing something.
I have a data flow task, a simple one, with an oledb source pulling data, using a select statement, from a sql server 2005 instance, and an ole db destination pointing to a table in a sql server 2000 instance. Both intances are standard edition. The table in the destination has a column which allow null values and has also a default constraint (getdate()), and this column is not present in the source. When I map the columns in the destination, I leave this column as "ignore", not being mapped to any column from the source. The problem is that when I execute the task, SSIS is trying to insert NULL value into this column, so the package fail with the error "can not insert NULL value into column myColumn". I wonder why is it trying to insert NULL value if the column is not mapped to any column from the source.
Is this a known issue or I am nissing something in the settings?
If the destination table has rowversion or identity columns, there is no problem ar all. I ignore those columns in the mapping and SQL Server feeds them as expected.
Thanks in advance,
Alejandro Mesa

Hi,
I'm having my first go at developing a destination adapter which will send data to an update Web Service.
I've got some rather big gaps in my understanding. I've been following the various samples I've found on the net and have validated my mapping and picked up all the available column names and datatypes which are appearing in the Input and Output Properties tab of the Advanced Editor but I only have a tab for "Input Columns" and not "Column Mappings".
Which method defines the availble columns for the user to map?
Let me know if I haven't given enough information.

Have to create SSIS package for the below requirement:
I have source data in 2 excel files. Data from both these excel files should be loaded to the same single Fact table.
The column names in excel files and table are not same. I have a Reference table which has the column mappings between excel and Fact Table.
I have to refer this Reference Tabel for column mappings, plus i have to add some derived columns (Created_Date) to load the Fact_Table.
I have given a sample data structure below:
Source Data
Excel1_Order.xls
OrderNumber    OrderQuantity    OrderDate
Order10001Â Â Â Â Â Â Â Â Â Â Â Â 100Â Â Â Â Â Â Â Â Â Â Â Â Â Â 01-01-2011
Excel2_Customer.xls
CustomerNumber     CustomerName    CustomerAddress
[Code] ....

-- 1 5000.00 0 --@X IS 10000 = 15000 - 5000(col1)
-- 2 1000.00 0 --@X IS 9000 = 10000 - 1000
-- 3 10000.00 1000.00 --@X IS 1000 = 9000 - 10000
-- 4 12000.00 12000.00
-- 5 300.00 300.00
-- 6 35000.00 35000.00
--in col2 i just put zero where col1 is substract from @X and continue for every subsequent order.
-- in 3 row value is 1000 becouse @X is that big (1000 left from col1)

Hi Guys
I have a table that contains codes for commodities.Some of the codes in this table have changed and some of them have not.So now i want to design a solution that enable me to map the new codes in a different mapping table to the old ones in the other table.I also want to retain the old codes because most of the archived data used the old codes.
The New code is the new code to which the Code must be mapped to.Where there is no new code, the current code is being retained.How do i design my table and queries so that i can use the new codes as if i was using the old code.I want to select products with a certain code but using the new code and mapping to the old codes or vice versa.
Please help.
The structure of the data is like this.

Using a stored Procedure, I want to select a record from a Table if a certain string appears in a specified column, so I use
CREATE PROCEDURE spSearcher
@String varChar(20)
as
Select Column1, Column2, Column3 from Table1
where Charindex(@String1,Column1) > 0
which works fine.
But the following doesn't work:
CREATE PROCEDURE spSearcher
@String varChar(20)
@ColumnName VarChar(20)
as
Select Column1, Column2, Column3 from Table1
where Charindex(@String,@ColumnName) > 0
How can I substitute a variable for Column1, so I can pass the name Column1 or Column2, or Column3, as desired?
Thanks in anticipation,
Peter Caspersonn.
