Help On Native SSIS Xml Parser With One-many Relationships In The Same Element
Jan 3, 2008
Hi All,
I receive data in the form of xml file and it has one to many relationships. Below I am giving you the sample node and how it should be parsed. Please suggest whether this is possible in SSIS using XML Task if not pls suggest a fast and efficient method.
<Element1>
<SubElement1>S1</SubElement1>
<SubElement2>S2</SubElement2>
..
..
<SubElement20>
<Child1>c1</Child1>
<Child2>c2</Child2>
</SubElement20>
<SubElement20>
<Child1>c3</Child1>
<Child2>c4</Child2>
</SubElement20>
..
..
<SubElement25>
<SubElement25Child1>s25_One</SubElement25Child1>
</SubElement25>
<SubElement25>
<SubElement25Child1>s25_Two</SubElement25Child1>
</SubElement25>
</Element1>
The above one is a sample xml. I should get 8 rows for the above element. There are 2 elements with "SubElement20" and it has 2 childs each. So there are 4 such nodes. The element "SubElement25" occured 2 times. Now we need to multiply these two counts.i.e. 4 * 2 = 8.
The relationship in the xml is one to many.
After parsing the xml I should get the rows in the following format and it should be one to one mapping only.
S1, S2, ....c1,... s25_One
S1, S2, ....c1,... s25_Two
S1, S2, ....c2,... s25_One
S1, S2, ....c2,... s25_Two
S1, S2, ....c3,... s25_One
S1, S2, ....c3,... s25_Two
S1, S2, ....c4,... s25_One
S1, S2, ....c4,... s25_Two
The options are as follows
1) Writing a custom source component to parse this xml and produces the rows in the specified way.
2) First write a XSLT or Style Sheet to break the above one to many relationships to one to one relationships and create an xml file and then use native SSIS xml parser.
3) Using the Script Task as the source component and do the parsing. But I think it would be difficult to handle and maintain.
If any other suggessions please share. Thanks in advance.

Venkat.
this is sanjeev, i have SSIS package, using my c# program i want to add one execute package task to this package's sequence container.
it is creating the new package with out any probelm. but when i opened the package and try to move the newly created exeute package task it is giving the following error.
the element cannot be found in a collection. this error happens when you try to retrieve an element from a collection on a container during the execution of the package
Informatica has an XML parser component that allows me to read an xml file from a data source (Oracle Clob attribute in table in this case), parse it out in our mapping, and then transform the parsed date.
Does anyone know if SSIS has similar functionality?

I€™ve been battling with a client who€™s supplied us with what they consider to be a legitimate CSV file. 1st off let me say that I understand that there€™s no CSV €œspecification€? per say, but here€™s the situation regardless.
The client has a test string in one of their fields that looks something like this:
He said "STOP" so, of course he stopped
The CSV best practice requires that you double quote, so a valid CSV filed would look like this:
He said ""STOP"" so, of course he stopped
Once this is placed into a comma delimited CSV it looks something like this
"Col1","Col2" "He said ""STOP"" so, of course he stopped","value in col2"
---------------------
So the problem here is that the client saves the above as a CSV, opens it in Excel and say - Look, Excel deals with this just fine €“ why can€™t you handle it?
Trying to explain to the client that SSIS can€™t deal with a field that has embedded commas in it but that Excel can is quite honestly a little embarrassing (especially considering the const difference between the two).
It seem that having embedded quotes in the filed is fine, but that as soon as you have an embedded comma €“ SSIS can€™t handle it, yet Excel can.
---------------------
That said €“ I€™ve also read quite a few posts where people flame the original poster saying €¦ change your delimiter. That€™s all good and well when you€™re the one generating the CSV but when your client knows hinks they€™re generating a legit CSV (according the Excel and quite a few other CSV parsers) it€™s not a pleasant argument €“ especially when you know that asking them to make this change is going to take a few weeks of your project timeline.
I know I€™m not the 1st person to experience the problem, but I did want to see if I could get a straight answer as to why the Excel CSV Parser would dela with this situation but the SSIS parser would not.
AFAIK I don't think so. Let me know if possible and how.
I'm talking about a SSIS package which owns a Execute DTS 2000 Package Task and from there it calls a DTS 2000. Programatically, from our VB .Net front-end app we're seeing only SSIS events (when validate and execute methods are called) and any kind of information is provided from RCW proxy (I suppose that internally it gonna be created in order to send messages between managed and unmanaged code).
When a task inside our DTS 2000 fails we're awaring by means a "generic message" such this:
Error: System.Runtime.InteropServices.COMException (0x80040427): Execution was canceled by user. at DTS.PackageClass.Execute() at Microsoft.SqlServer.Dts.Tasks.Exec80PackageTask.Exec80PackageTask.ExecuteThread()
I'm getting an error in a Execute SQL command task that returns XML. The error is: An invalid character was found in text content. I traced the error to this article:
http://support.microsoft.com/kb/238833
My question is how would I go about changing the encoding scheme? I've been able to run this package successfully on our dev SSIS box, but it's failing in prod. I suspect because the encoding schemes are different. Where do I go to verify this? How would I change it?
I get a parser error on a particular page that reads:

I need to parse SQL statements directly and extract each segmentindividually. Is there a way reference the Microsoft SQL Parserdirectly from VB.Net?Thanks!*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!
Looking for TSQL stored procedure code to parse a single column's value into pieces (each piece stored in a seperate variable) for a subsequent update of other columns on this row -- (generically):
1. Declare/Open cursor on TBLx where COOKIES like '%CLIENT1=' or like '%CLIENT2=%' or like '%CLIENT3=%' 2. Fetch row; initiate 3 Loops to locate the trailing values of CLIENT1=nn, CLIENT2=nn,CLIENT3=nn (eg. CLIENT1=3243, CLIENT2=11, CLIENT3=4451) 3. Save the 3 values in variables (eg @VARclient1=3245, @VARclient2=11, @VARclient3=4451) 4. UPDATE where current of cursor.. SET COL1=@VARclient1, COL2=@VARclient2, col3=@VARclient3)
Caveat.. in step 2 above, the various CLIENT strings can be listed in various orders in any various start positions w/in the COOKIEs column) (eg. CLIENT3=732,CLIENT1=9,CLIENT2=32 ----- starting in a variable position)
I'm familiar w/ the CHARINDEX feature... Any smaple code would be greatly appreciated.. thx in advance!
Back last October Paul DB mentioned the MS Log Parser tool and that he was using it for Exchange Transaction Logs.
I'm not an SQL person myself and would dearly love a little help to get started. Paul, I would be most grateful if you could post/send me even one example of the command line you use to get info out of Exchange T Log files. (I'm using 5.5 at present.)
When I'm in query analyzer writing a stored procedure, if I make a mistake it will frequently go on and create the procedure without any warnings...I am on 9.00.3042.00, developer edition when this happens.
i.e., i had a stored procedure that had input parameters, and I declared a parameter @xyz nvarchar=NULL. It created the stored procedure anyway, and parsed it correctly as well. In fact, clicking the little 'parse' checkmark doesn't appear to do anything at all...
I didn't find out about my error until I ran the script in a 2000 database.
Is this a known defect? Will there be a patch? Is there a setting I don't yet know about to fix this?
I have a script task that is supposed to read and parse a fixed width source file.
Basically, I want to make the FieldWidths dynamic so that I'll be able to reuse this package with different files. So Instead of hardcoding the field widths directly into my script task, I want it to be stored somewhere that the package can get when executions starts. Is there a way of doing this?
The code looks like this:
Using Reader As New TextFieldParser(mTempFilePAth)
Reader.TextFieldType = FieldType.FixedWidth
Reader.SetFieldWidths(1, 8, 8, 8, 4, 8) <-- I want to change this to handle dynamic widths.

This is a question for anyone familiar with log parser. I use log parser to insert the IIS log information into our SQL database. It has been working great but we have now run into 1 problem.
I have been using a SELECT * statement before to put all the IIS log info into a SQL table and it works fine. I want to add 1 extra column to the SQL table though (a primary key). It wont let me use the select * statement anymore because the fields do not match. I even tried specifying the fields one by one but it will not work because there is a different amount of columns now.
What I did was I modified the table already there with a new column (RecordID which is a auto-increment primary key). Can someone please give me advice on how I should persue this? Keep the table with the new design and input the data differently, or somehow specify this new primary key column in the logparser statement.

Why does XML Source in MS VS 2005 Integration Services Data Flow Sources XML Source not pick up the root element?
The problem is the following example: <root createddate="2008-01-01"> <elements> ... </elements </root>
The XML Source picks up everything after the first element which is the root element but it does not seam to pick up the root element where there is a need for the createddate attribute.
Is there a soultion for this problem or a workaround?
Hi, I have simple report with RS 2005. I use matrix component. I€™ve added €œSubtotal€? element to the row and It works perfect. But I would like to make some modification to it and I€™m looking for expression of it, but I can€™t find it - there's just "TOTAL". Also On layout page I see text box €œTOTAL€? and that€™s all. Where can I find it? Thank you Tomasz
