Using XML Source In SSIS Vs Script Source To Parse Xml Files.

Sep 14, 2007



Hi

I am having a huge xml file with nested section.
i also have a xsd file for that xml.
i have a destination table where the data from the xml should be loaded into.
i am using the xml source transformation. But o get all the data i need to use multiple merje joins to get the data in a single row which i can insert into the destination.i was not quiet convinced with using so many joins.

so i tried using the script source transformation where i am using xml objects to get the node and dynamically construction the data row. and the output is then inserted into the destination.
on comparing the two approach the one using the script source is working much faster than the xml source transformation.

i wanted to know is there any limitaion using the script source to parse through xml files.
also i would like to know any other better way of getting the data from xml source without using the joins.

SSIS - Dealing With Missing Source Files

Jul 9, 2007



I want to skip running the SSIS data flow task when the source file is missing. We have a scheduler that copies the source file to the staging area. This SSIS package runs as SQL server job. So when a SSIS package fails due to missing file the remaining steps in the SQL scheduler won't execute. I want to handle the missing source file condition grace fully. Please advise.



Thanks in advance.

How To View AS400 Library Files From OLEDB Source (SSIS)

Jan 3, 2007

HI,

I'm trying to get data from AS400. using OLEDB source as my connection. i'm using IBM OLEDB provider for iSeries. and working on standard edition of SQL Server 2005.

While using OLEDB source task when i set my access mode to 'table or view' and try to see list of available libraryname.tablenames, i do not get and tables

where as when i use Data access mode as 'SQL Command' i can get data (can only see preview of data) from AS400 but not able to insert that into my destination table. At run time task Fails with the error mentioned below.

I have configured Data links tab inside the OLEDB connection manager also, but when tried to set a default library it gives me error. : "Error code :CWBZZ5042" - ( catalog is invalid ) but it does exist.

Is there some settings that needs to be done from AS400 side or SQL Server side to view the available libray and its tables ?

Can some one help me on the same.

thanks in advance

Shah

T-SQL (SS2K8) :: Extracting Source / Dest Column Details From SSIS Package Files?

Jun 30, 2015

We have several hundred very simple ETL SSIS 2K8 package files (*.dtsx).

I'd like to be able to interrogate them to determine source and destination fields.

There's no great need to map source to dest or to extract data types.

So far, the most promising candidate is to load them using OPENROWSET into an XML field in a SS table.No problem there, but querying using OPENXML has me stumped.

The package files will change a couple of times per year, so the process needs to be repeatable with minimal manual intervention.

Integration Services :: Metadata Change In Source Disturbs All Configuration Of Source

Jun 18, 2015

I have a got a package with source as sql table which has got 50 columns. We are using only 10 columns out of this. Recently one column name has changed and thus throws error invalid mapping. When I open the source to do the changes noticed that all the colums are prselected now and also the datatypes got changed to default ( I had changed the datatypes as per my requirement while i developed). So now I had to select required columns from source and redo the datatype changes in advanced editor.Is there any option which doesnt disturb this settings and we just need to correct the mapping alone.

Longarse Txt Source Files

Oct 24, 2006

I thought i share this lil thought/tip with ya'all:

I have .txt import files which have huge amounts of columns (this time about 150 - 200). And i need to import 3 of those files. I do have the definitions for columns - but to fill out 200 column definitions in SSIS editor takes u a while. (And suggest types is quite useless due to 1000 sample row limitation - not to mention that if you identify Boolean fields using Y,N - i throws errors on import - so you are most of the times better off defining your own columns).

Fortunately for me - majority of the fields is similar (over 100 fields) - so I can copy and paste the flat file connection and make changes to copied file connection

I guess my wish for future version is that flat file manager could create column definitions from pre-defined format document which would look like:





1 Acres
float
8


2 AgentList
varchar
20


3 Area
int
4


4 Fee
int
4


5 FeePaid
varchar
10

XML TASK XSL Variable: Exception 'Property New Source Has No Source Xml Text'

Dec 20, 2005

Hi,
I want to transform an xml flow to an html flow. For this, I create an XmlDataDocument, I add on it, all that I want, and I store it in a file (in a dataflow task).
After that, in an xml task, I set the input properties like that:
Operation type: xslt
SourceType: File connection
Source: ras.xml
 
All works fine. But now, I want to use a variable to store my xml data. So, instead of storing my data in ras.xml, I store it in a variable like that:
 
Dim v As Microsoft.SqlServer.Dts.Runtime.Wrapper.IDTSVariables90
Me.VariableDispenser.LockOneForWrite("RAS", v)
v("RAS").Value = doc.OuterXml
v.Unlock()
 
and in the xml task, I set configuration like that:
 
Operation type: xslt
SourceType: Variable
Source: user::RAS
 
But when I execute, I got this following exception:
 
Error: 0xC002F304 at Format HTML Mail, XML Task: An error occurred with the following error message: "Root element is missing.".
Error: 0xC002928F at Format HTML Mail, XML Task: Property "New Source" has no source Xml text; Xml Text is either invalid, null or empty string.
 
Furthermore, when I want to debug it, in replacing the xml task, by a script task, I can see that in my RAS variable, I get the xml data which is well formed.
 
<?xml version="1.0" encoding="UTF-8"?>
<root> €¦
</root>
 
(When I store it in a file, I can see it in IE)
 
Have you got an idea ?

Loading Data Using Ole Db Source With Input Source Being A View

Dec 13, 2007

I was trying to load data using SSIS, Data Flow Task, OLE DB Source, source was a view to a OLE DB Destination (SQL Server). This view returns 420,591 rows from Query Analyzer in 21 seconds. Row length is 925. When I try to executed the Data Flow Task from SSIS, I had to stop the process after 30 minutes, because only 2,000 rows had been retrieved. I modified the view to retun top 440, 000 and reran. This time all 420, 591 rows were retrieved and written in 22 seconds. Next, I tried to use a TOP 100 Percent. Again, only 2,000 rows were return after 30 minutes. TempDB is on a separate SAN Raid group with 200 gig free, Databases on a separate drive with 200 gig free. Server has 13 gig of memory and no other processes were executing.

The only way I could populate the table was by using an Execute SQL Task and hard code an Insert into table selecting data from the view (35 seconds) from SSIS.

Have anyone else experience this or a similar issue? Anyone have a solutionexplanation?

XML Source File Change Issue (same XSD Different XML Files)

May 26, 2008

hi all,
i'm facing a small problem with xml file source.
let me explain the scenario!

we have 4 source xml files with same format, each file has around 25k rows of records.

XML Source
Derived Columns
Data Conversion
Conditional Split
OLEDB Destination

its executing fine.
once we change xml file source (second xml file with same xsd),
all other components are showing errors. the error is that

Error 21 Validation error. Staging: DTS.Pipeline: input column "LateRsnCd" (17917) has lineage ID 19380 that was not previously used in the Data Flow task. OnTimeOrderEntry.dtsx 0 0

lineage id has changed it seems, when we are giving new file as xml source. of course xsd is same, but its not taking with names.
to resolve this, if we open that errored task, select all, map using column name--> apply. its getting mapped with the columns as it is in the input.
still the conditional split will show the error.
if we open the conditional flow and give ok, the error has gone, i think some meta dat change has occured in the opening task and giving ok.

what could be the possible probelm and how to fix it?
one more doubt, how can we include xml source in the configuration file? since it doesn't have connection manager, i'm struggling with it for dynamic file selection for xml.
i dont want hard code the source file path (as it reside in the server) in the poperties of the xml source task.
can i have some suggestions please?

Source Code For The Standard SSIS Components That Come With SSIS?

Jun 2, 2006

Hi,

I'm finding that the standard components often just don't quite meet my
needs, but would only need some fairly minor changes to save me and my team a lot of
work (and produce more elegant solutions). So I was just wondering whether the source code was available for the standard components that come with SSIS, or if there is anyway to extend their functionality?
Or do you just have to start form scratch?

Thanks,

OLE DB Source To Flat File Destintation Using Fixed Width Columns - Determining Source Column Width

Feb 13, 2007

Hi,

I am trying to create a program that transfers tables to flat files.
At this point in time, I have suceeded in created one that creates delimited files.

However, I am now trying to create fixed-width files as you can do with the SSIS designer, but programatically.

Is there a way to programatically determine the width of a column from the source table? I can not seem to find any kind of function or member that stores this information or allows me to retrieve it.

I know what I need to change in order to set a width for a column, but I just don't know how to find the width without just asking the user to provide one.

SSIS And Data Source

Aug 10, 2007

Hello,

I have SSIS solution which has multiple packages and one Main package which starts all others.

I also have 2 Data Sources which I use on each package.

I need to do my testing on different Data Sources. When I try to change Data Source from one database to another - SSIS is getting confused and fails on the connections or starting to insert to the previous database.

Could you please explain the steps for doing it. What is the problem here?
Can I use Windows Attentications in data source or use special account?

Also some confusion here with Config file. Should I create Config file just from Main package or from each package. For now I am working with a Source code, but later I would need to change connections string before running the executable. If I change the string in my Main package - would it be understandable in all others?

Please give me details here.

Thanks.

SSIS OLE DB Source Error

Oct 3, 2006

I am creating an OLE DB Data Source in an SSIS Data Flow - it is calling a SQL Server 2005 stored procedure, which accepts 3 parameters and returns a result set, but I get the following error:

"There is a data source column with no name. All data source columns must have a name."

I have have tested the output of this proc a million times, and every column has a name! I am also able to call a different proc in the same way, without error:

EXEC pProc @DT = '20060928', @Id = 1015, @Debug = 0

Any ideas what could possibly be causing this error - assuming all of my columns DO have names??

Thanks : )

SSIS SQL OLE DB Source - SQL Command Vs Mapping

Oct 10, 2007

I created a Stored Proc to compute all the data I need to export to a CSV file.
I use the provider MS OLE DB Provider for SQL Server.
It's a very simple package with a single Data Flow Task.
This flow task is using an OLE DB Source to call a simple SQL Command : Exec MyStoredProc.
There are no params.

This Stored Proc is using table variables to compute the data.
It takes about 10 seconds to return anything.
The problem is that the mapping doesn't work with the OLE DB Source.
There are no fields at all shown in the mapping screen.

I tried to replace the Stored Proc by a version which only returns fields and no data.
Then the mapping would work just fine.
The package is then compiling and working fine.
But everytime I put back the real stored proc, even without changing the SQL Command, the SSIS execution breaks at execution.
It keeps saying :

"Error: 0xC0202005 at Data Flow Task, OLE DB Source [477]: Column "RecordType" cannot be found at the datasource."

My guess is that SSIS doesn't wait the 10 secs and thinks the Stored Proc is not returning anything.
What can I do to make this work ?


Thanks,

Vincent

SSIS Project And Source Control

Aug 26, 2007

Our team has the following problem:
I create a SSIS project in VS and add it to Team Source Control. When the project and all it's files exist on a machine and I want to open the project from Source Control, everithing works fine, but when another developer, who doesn't have the files on his machine, wants to open the project from Source Control he is required to check out the project file.

I've investigated the problem and found out that each project has a database file (with .database extension) and project file contains a reference to it. Once the user opens from Team Source Control a project that isn't presented on a target machine, the VS creates a new database file on a local machine and insists to change the reference in the project file.

Does anyone have a workaround for the problem?

Thanks

SSIS XML Source With Random Child ID??

Jan 17, 2006

Hi,

I am trying to load a XML document using SSIS into relational tables and pulling my hair out.

In it's simpliest form I have:

<Batch>

<POSBasket>

<Header>

<SomeDetail/>

</Header>

</POSBasket>

<POSBasket>

<Header>

<SomeDetail/>

</Header>

</POSBasket>

</Batch>



Now, when you have a parent child situation, you get a column in the output called xxx_Id, in my case, POSBasket_Id. This allows you to relate your header back to your root and SomeDetail back to header etc etc.

Loading all of this in parrallel does not work because there is nothing unique once the load has happened more than once. i.e. You will have repeating POSBasket_Id's as well as Header_Id's.

I ended up loading POSBasket into a table with an identity column. Once done, I would load the header details and do a lookup (eek) on the POSBasket table by using POSbasket_Id "where isComplete = 0" (A flag to tell me current import).

Great, this works find with 1 item in my document. Add a second (2 POSBaskets) and it randomly works. (???) Add more and it hardley works. The look ups are failing with "no match found".



On using Data Views, I see that each XML source creates different POSBasket_Id's. Some matching, some not. Also seem to randomly match.

My question is why? Why would there be the ID if they differ when loading them from the same document? They not even unique across sources.



Bug or "by design"?

Anyone got a better method for doing this?



Cheers,

Crispin

Validating Source Schema Using SSIS

Sep 23, 2007

Greetings!!

I have a MsAccess db containing a table called Employees which i am transforming to a staging table in Sql server 2005. Everything is working fine. I am using Foreach File enumerator and uploading the files one by one.However I now plan to validate the schema of MsAccess before uploading it. For eg: My employee table in msaccess is as follows :




Code Snippet
Employees
empId int,
empName varchar(60),
empAge int




Since the files come from different vendor, while looping, i want to perform a check if the empid or empAge are not of type long or string etc. If they are of type smallint,i have no problem.

However if they are larger datatypes than the the ones kept in Sql server, then the file needs to be logged in the db with the reason and moved to the error folder. In short, if the datatypes in access tables are smaller than those in Sqlserver, allow it, otherwise reject it. THe schema of Sqlserver table is same as of that of Employees in msaccess.

I want to compare the schema of the incoming access tbl fields with my desired schema and all mdb's having data types that are higher or incompatible with the desired schema should be moved to the error.

How do I do it.

Thanks ,
Ron
