Reading From A XML Source

Mar 22, 2006

I am trying read certain attribute from a XML Source based on a particular attribute.

My XML source has the following Structure:<Database ID = "1" Source = "ABC" ></Database><Database ID = "2" Source = "ABC" ></Database><Database ID = "3" Source = "DEF" ></Database>.

I would like to fetch the list of IDs filtering upon Source = "ABC". (which should idealy give me 1,2)

I tried using the For Each Nodelist Enumerator By specifying the Enumeration type as Node and IDrect Input for the OuterXpathString as DATABASE[@Source="ABC"].

The for each loop fails giving the following error. Data is invalid. line 1 position 1.

Can anyone help me out with the same. Is there any other way around to obtain the required result?

XML Source Not Reading Any Records

Sep 19, 2006

The problem started off as:
I have a webservice written in VB.NET that simply returns a System.Data.Dataset. I want to use the dataset in SSIS.

So i decided to do this:
Save the returned dataset returned by the WS to an XML file. so it is sitting there, and looks like a fully valid XML file

<?xml version="1.0" encoding="utf-16"?>
<DataSet>
<xs:schema id="NewDataSet" xmlns="" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">
<xs:element name="NewDataSet" msdata:IsDataSet="true" msdata:UseCurrentLocale="true">
<xs:complexType>
<xs:choice minOccurs="0" maxOccurs="unbounded">
<xs:element name="Table">
<xs:complexType>
<xs:sequence>
<xs:element name="Name" type="xs:string" minOccurs="0" />
<xs:element name="SourceRecord" type="xs:string" minOccurs="0" />
<xs:element name="CombinedTitle" type="xs:string" minOccurs="0" />
......
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:choice>
</xs:complexType>
</xs:element>
</xs:schema>
<diffgr:diffgram xmlns:msdata="urn:schemas-microsoft-com:xml-msdata" xmlns:diffgr="urn:schemas-microsoft-com:xml-diffgram-v1">
<NewDataSet>
<Table diffgr:id="Table1" msdata:rowOrder="0">
<Name>Member</Name>
<SourceRecord>99998</SourceRecord>
<CombinedTitle>Mr</CombinedTitle>
<CombinedFirst>Sample</CombinedFirst>
........
</Table>
</NewDataSet>
</diffgr:diffgram>
</DataSet>


I then use the XML source connection to connect to it. It sees all of the columns correctly, but when i run and put a watch on it, or try to output the results to a .csv file, no records come through.

Any ideas on why there aren't any rows comming through?
i'm using SQL2005 with no SP1

Reading Dates From An XML Source Adapter

Oct 30, 2007

I am using an "XML Source Adapter" in an SSIS Package to try and load an XML file into a database table. But having trouble with a date field.
The XSD defines the field as:-



<xs:element minOccurs="1" name="DateTime" type="xs: string" />

The XML looks like this:-


<DateTime>12/31/2007 10:12:14.123</DateTime>

And the database table column is defined:-



[DateTime] [datetime] NOT NULL,


So in the Data Flow I have a "Data Conversion Transformation" converting [DT_WSTR] to [DT_DBTIMESTAMP].
However, when I run the package I get:-


Error: 0xC02020C5 at Load XXX File, Data Conversion 1 [13550]: Data conversion failed while converting column "DateTime" (15100) to column "DateTimeDT" (15422). The conversion returned status value 2 and status text "The value could not be converted because of a potential loss of data.".


So what how do I fix it?
I don't mind losing some miliseconds of precision, so I have tried configuring the error output of the Data Conversion for this field to "ignore failure" for "Truncation". But that seems to have no effect.


I'd be happy to change the XSD to:



<xs:element minOccurs="1" name="DateTime" type="xs:dateTime" />

But the "XML Data Flow Source" doesn't seem to support the dateTime data type.
Any suggestions appreciated. Thanks.

Errors Reading From An Excel Source

Nov 27, 2007



Hi,

I have an Excel spreasheet - the first column is text, the second numbers, the third a mix of the two. If I point An Excel Source at this in my data flow, it will import the first two columns without problem, but not the third: all cells containing text are being imported as nulls, but those containing numbers are imported just fine.

Even if the numbers are stored as text, they are converted into numbers at import and genuine text is still discarded. It's treated as if the entire column is numeric if there's just one numeric value in it.

I can get around this by creating a .csv or .txt file from the excel file, but that will add an extra layer of admin to this process and I'm tryuing to make it as seamless as possible

Reading From SSIS Flat File Source?

Feb 9, 2012

I have a simple SSIS package -> It reads a local text file which has 10 rows of data ( id, name, telephone # ) and puts it into a table.

It uses the "SSIS Flat File source" to read and a "SQL Command" to insert into the table. I can see that it reads line by line and puts each line into one row in my table.

Now, my production data is over 5 GiG of mainframe data and it seems their data is arranged in some hierarchical form.. so the position or arrangement of data in that file is important.

I pulled the data using my package and as far as I can see , my SSIS package pulled one line at a time ( from the flat file) and pushed it into my table. For each row, I also created an identity column in my table to be able to identify the positional arrangement of the hierarchical data and then use relational mappings to suit our business needs.

In all of this, my assumption is -

"SSIS reads one line at a time, inserts to my table and goes down to the next line .

It does NOT read a snapshot of rows from the flat file so as to write them into the table using internal ordering methods based on that particular snapshot "

My question is .. is my assumption correct ?

Hi,

I'm using a script task as source and I need to read a global variable.

I tried stuff I found on the internet, but they all use Dts.VariableDispenser.LockForRead(varName)

This gives an errero on 'Dts.' saying it can not resolve it.

Excel Source Not Reading Newly/appended Rows

I am trying to ETL from excel source to SQL table. When I created the package my excel had certain number of rows. Later if I add (append) few more rows in the spreadsheet ... the ssis package (also in excel source preview) not reading the newly added rows. Suprisingly it is reading new rows if they are inserted in between existing rows.

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.

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?

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.

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.

DataReader Not Reading

Jan 13, 2004

Why won't this dataReader read?

Dim objCon2 As New SqlConnection()
objCon2.ConnectionString = "a standard connection string"
objCon2.Open()

Dim objCommand As SqlCommand
objCommand = New SqlCommand(strSQL, objCon2)
Dim objReader As SqlDataReader
objReader = objCommand.ExecuteReader()

Label1.Text = objReader("email")

strSQL is a select command which I've checked (using SQL Query analyzer) does return data. I know the connection string is valid (and I presume if it wasn't that it'd fail on objCon2.open, which it doesn't).

So why oh why do I get this error on the last line (and yes, there is an "email" field in the contents of the reader)

System.InvalidOperationException: Invalid attempt to read when no data is present.

Help With Reading Database.

Jun 29, 2005

I have this code that I hacked together from someone else's example.  I kind of understand how it works.  I just don't know if it will and i am not in a location right now to check.  I was wondering if I did this correctly first, second how can it improve and should i do something different.  Basically i just want to check the password in a database. I am passing the username and password to this function from another functioprivate bool authUser(string UserName, string Password){ string connectionString = ConfigurationSettings.AppSettings["DBConnectionString"];  SqlConnection DBConnection = new SqlConnection(connectionString);  bool result = false;  DBConnection.open() SqlCommand checkCommand = new SqlCommand("SELECT password FROM Users WHERE userName='" + Password + "', DBConnection) SqlDataReader checkDataReader = checkCommand.ExecuteReader();
 if(checkDataReader.GetString(0) == Password) {  result = true; } else {  result = false; } checkDataReader.Close(); DBConnection.Close();
 return result;}Thank you Buddy Lindsey

Reading Results Into .NET

May 20, 2008

Hi. I want to write a function to retrieve all records from a "Parts" table so that I can read these records in .NET.

SqlDataReader reader = sqlCmd.ExecuteReader()

while( reader.Read() )
{
int x = reader["id"];
string partName = reader["name"];

// Do stuff with data here //
}


My question: How should the function be written?

Should I create a PROCEDURE and just call a SELECT statement?

CREATE PROCEDURE getPartsList()
AS
SELECT part_id as 'id', part_name as 'name' FROM parts


Or should I create a FUNCTION that returns a TABLE? If so, is this the correct syntax?

CREATE FUNCTION getPartsList()
RETURNS TABLE
AS
RETURN (SELECT part_id as 'id', part_name as 'name' FROM parts)


Thanks for reading
