Consuming WCF Service With Complex Data Type In SSIS

Oct 9, 2007



Hi,

Need a guidance on consuming the WCF service with complex type in the SSIS package.
I have a WCF service with complex type inside the complex type (Nested complex type) in the web method as an argument. When I try to use this WCF service in the SSIS web service task, I get an error "The web method has unsupported arguments".

I am able to consume the WCF service with the web method having Complex type and simple/prmitive type in side that as argument.

For example:

The web method in WCF service which accepts the argument as comlex type say "Employee" whose structure is:

Employee
{
FName String;
LName String;
Age int
}

It is possible to consume this WCF service and pass the arguments.

But when the Employee complex type is changed to have one more complex type in side it it give the above mentioned error. The Employee type is modified as:

Employee
{
FName String;
LName String;
Age String
Type EmployeeType;
}


EmployeeType
{
type string;
}

Now I get the error Web Method has unsupported arguments.

Can this be done in SSIS?

SSIS Web Service Complex Type Inputs

May 21, 2007

Hi,

I am trying to make a call to a third-party web service in my SSIS package. The request has custom complex data type as the parameter. As has been pointed out in this forum before, the Web Service Task only lets you assign the outside parameter from a variable, not the internal parameters needed to create the complex data type.

To be more specific, the web service input wants a 'ContactSearchRequest' parameter. I can assign this from a variable. If I click on the 'value' field under the 'Input' section for the web service task, it shows me that the 'ContactSearchRequest' data type is made up of the following:

contactId - long
numResults - int
offset - int
passKey - string
searchParam - string
sortType - int

Unfortunately, I can't assign these internal parameters from a variable, at least not through the web service task interface.

My next thought was to create a variable of type 'object' and then set it in a script task prior to calling the web service task. However, I'm not sure exactly how to do this. How will my script know about the class definition of 'ContactSearchRequest'? Do I just create a class called 'ContactSearchRequest'?

I've used this same web service in a .NET C# project and after I imported the web service, visual studio knew all about the custom data types. How do I do something similar in SSIS?

Of course, the easiest solution would for Integration Service to allow me to set those internal parameters via variables, but we're apparently not there yet.

Any suggestions?

Thanks,
Trey

Consuming From Web Service And Load Data Into SQL

Jun 11, 2007

Hi:



Can someone help me with a SSIS package that would consume from a Web Service (in fact two of them) and then load the data into SQL Server. I currently have Web Service task which connects to ForEachLoop task, and inside the loop task, I have a DFT. I am thinking, I would need to call the webservice utilizing the Web Services Task, and then store the output in a Full ResultSet variable. In my loop, I would like to loop thru the resultset, and store the data into SQL server. Inside the DFT, how would I construct this mechanism? Also, is this a good way to consume from a Web Service and then populate SQL Server? Are there any alternate ideas on this? Any documentation on this yet? Thanks.

Integration Services :: Passing Complex Type As A Variable In Web Service Task

Oct 5, 2011

When you pass a complex type (the one represented by class) to a web service the BIDS UI allows you to enter values for every field of that type as constants. But what if you want to pass a variable? Once again the UI allows you to specify a variable for that complex type parameter. But how to make this variable in SSIS?I understand it should have the type of Object. But how to specify what the runtime type of this object is? And how to assign all fields to that object?

Web Service Data Source Complex Parameters

Feb 8, 2007

I am building a report that takes a web service as data source. This web service does not take primitive types as parameters. The signature is something like this:

<soap:Body>
<GetXml xmlns="myreports.ws">
<root >
<TP Name="string">
<B Name="string" Surname="string">
<SA xsi:nil="true" />
</B>
<B Name="string" Surname="string">
<SA xsi:nil="true" />
</B>
</TP>
<TP Name="string">
<B Name="string" Surname="string">
<SA xsi:nil="true" />
</B>
<B Name="string" Surname="string">
<SA xsi:nil="true" />
</B>
</TP>
</root>
</GetXml>
</soap:Body>


My question is: how do I pass the xml to the web service from reporting services.

I have seen examples with simple types. They do it with this query:

<Query>
<SoapAction>myreports.ws/GetXml</SoapAction>
<Method Namespace="myreports.ws" Name="GetXml"></Method>
<Parameters>
<Parameter Name="Parameter1">
<DefaultValue>some value</DefaultValue>
</Parameter>
</Parameters>
<ElementPath IgnoreNamespaces="True">
GetXmlResponse{}/GetXmlResult{}/diffgram{}/NewDataSet/Element{@Attribute1,@Attribute2}
</ElementPath>
</Query>

But there are no example on using xml directly instead of parameters. Can anyone help me? Where do I put my xml?

COnverting Numeric Data Type (Oracle) To Date Data Type Using SSIS

Mar 7, 2007

We have some columns in a table where the date is stored as 19980101 (YYYYMMDD). The data type for this column is NUMBER(8) in Oracle.

I need to copy rows from Oracle to SQL Server using SSIS. I used the Data Conversion transformation editor to change it to DT_DATE, but the rows are not being inserted to the destination.

On Error, If I fail the component, then the error is :

There was an error with input column "ORDER_DATE_CONV" (1191) on input "OLE DB Destination Input" (29). The column status returned was: "Conversion failed because the data value overflowed the specified type.".

Using Service Broker For Reliably Transmitting Events To Consuming Applications

Apr 16, 2006

Hi, I have a scenario in which an application generates events upon updates to the database, which need to be reliably transmitted to consuming applications running a) other SQL Server instances and b) as remote web services.

Now,

1) I am planning to use SQL Server Notification Services to generate these events, and allow the consuming applications to subscribe to them.

2) The events will be sent to a ReceiveEvent service, which will then process the event and put it in the respective queues for the Subscriber (consumer) applications.

3) The services representing these consumer applications will then get activated, and sent the message across directly to the service broker on the consumer side in case of situation a - where there is a SQL Server on the other side

4) In case the other side is a web service, I plan to make a SOAP request directly from my queue handler, and depending on the response received, decide whether to commit or roll back that particular transaction.

Does this seem like a good solution? I am very new to the Service Broker, and I am still getting my hands dirty. Any comments/suggestions would be very highly appreciated!

Regards,

Siddhesh

SSIS Complex Joins From Seperate Data Sources

Oct 30, 2007



Hi,

I'm trying to replicate a SQL join across two seperate data sources in SSIS. If I were to write SQL to do this, it would be as follows:


SELECT Costs.CostRateEntryId,

Costs.UserId,

Costs.HourlyRate * 8 AS DailyCostRate,

Dates.DateKey,

Dates.ActualDate,

FROM Costs

INNER JOIN Dates ON Dates.ActualDate >= Costs.EffectiveDate AND Dates.ActualDate <= Costs.EndDate


Unfortunately, as the tables 'Dates' and 'Costs' are in two seperate SQL2005 systems, I can't really do this. I was hoping that it could be achieved in SSIS, but I cant seem to find any way that I can do a join that's <= or >=.

Can anyone help?

Thanks

Consuming Oracle (9G) In SSIS On X64 Server

Nov 25, 2007

Hi,

I believe this question has been covered quite a bit, but none the less I wanted to ask it as I still have no resolution at the moment. I am consuming a table from Oracle which has a data type of NUMBER. When I use a .Net Provider to consume the data, the SCALE defaults to 0 for these select columns and thus we lose any decimal point information for these columns. I have tried using both the .Net Provider and the .Net for OLEDB providers for ORACLE. Both seem to suffer from this. The SSIS server itself is a Win 03' server on x64 hardware architecture. Also, when trying to use the Oracle Provider for OLEDB it throws a design-time error stating "Error in Initializing Provider".


Thanks!

Hello everyone,
I am newbie in SSIS and I have one problem.
I have defined in Control Flow one WebService Task, specified the WSDL-File.
I have chosen one method from WS as Input. But this method requires one parameter of the ArrayOf_xsd_string type.
If I try to choose it, I receive following error:

===================================
This complex type does not contain any properties. (Microsoft.SqlServer.WebServiceTaskUI)

Ambiguous Complex Type Definition With XML Source. Workaround?

Jan 19, 2006

Hi,

This could well be down to my _limited_ knowledge of XSD.



I have a document and SXD supplied by 3rd party.

Both documents are valid, according to XMLSpy.

When I give the document and xsd to SSIS XML Source it complains about ambiguous complex types.



In the XML doc there is an element called Allowance that has child elements.

There is also a group which references many other elements including Allowance.

When I remove the group, SSIS stops complaining about allowance.



Would the problem stem from SSIS creating an output called Allowance ('cause of it's children), getting to the group and again, 'cause allowance has children, try create another output called Allowance.

Is my understanding of this correct? Is there a work around for a situation like this?

The only thing I can come up with is deleting the group....

Possible to alias an element? Could alias the Group > Allowance g_Allowance.



Cheers,

Crispin

Help Passing Complex Variable Types To A Web Service Task

Feb 23, 2007

I need a little help here and appreciate any insight into this issue.

I am building an SSIS package that retrieves data from a database to use in a web service task. So let me give you a little more broad overview of the package so you can understand how this is supposed to roll. A database is queried and those values are dumped into a recordset. A foreach loop uses each row of variables to call the web service and dump the returned values to another database. The first database holds a bunch of fields, but the four fields of interest are: a StartDate (DateTime), a StartFormat (single char), an EndDate (DateTime) and an EndFormat (single char). The output from the query of the first database is the input in the signature of a web service's .Load method. Sounds easy, right? Sure, why not?

Well I dragged the Web Service Task on to the pane and took a look inside. Lo and behold, I can hardcode the variables in for the web service or I can assign the inputs to package variables. How fancy, thanks Microsoft!

But that's where the difficulty begins. The method call for the web service looks like this: service.Load(string, int, GTTimestamp1, GTTimestamp2). The web service is expecting a string, an int, and two objects of the type GTTimestamp, which is a very simple class defined as this:

<System.Xml.Serialization.SoapTypeAttribute("GTTimestamp", "http://util.gtdw.pci.com")> _

Public Class GTTimestamp

Public calendar As Date

Public displayFormat As String

End Class

In the input pane for the Web Service, when I click in the value of the two GTTimestamps like I'm going to hardcode them in, another window pops up saying "Enter the values for complex type -in4" and the pane looks exactly like the previous pane with one very important exception: There is not place to check to assign the value from a package variable!!! Dang you Microsoft!!! I don't really understand why they would leave us out to dry on this... Oh, well, maybe they'll take care of it later...Time to work around it.

SSIS does allow you to create a variable of type System.Object, so after playing with the Web Service for a few minutes and giving up on that, I decided to create a script task that is supposed to create two GTTimestamp objects and assign them to two object variables in the package for passing to the WebService Task. The first challenge was to get the web service to play nice with the script. For those who have never done this, use a command prompt and the wsdl.exe to generate a .vb or .cs file to add to your script file using the right click, add existing item...

Once the file was accessable to my scripts, I created two GTTimestamp objects and assigned them to the Package variables of type System.Object. Running the package, I got this error:

"Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebserviceTaskException: Could not execute the Web method. The error is: Type 'ScriptTask_8c868490237b4220b582bdc7c7a3ecae.GTTimestamp' in assembly 'VBAssembly, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' is not marked as serializable.

Not marked as serializable, huh. Okay, so I made the GTTimestamp serializable by adding the <Serializable()> before the class declaration. Then the error changed to:

The error is: Type is not resolved for member 'ScriptTask_8c868490237b4220b582bdc7c7a3ecae.GTTimestamp,VBAssembly, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'.

And here I am, at a loss for what to do from this point. I'm a little lost, so I thought I'd stop and ask for directions. I'm sure I'm not the first to want to use complex variable types.

Only two options at this point. One is to try and store the GTTimestamp in the database and see if SSIS can deal with that. I'm not sure how to store objects in a database or if that is even an option for me, but it came to mind so it made it into this post. The other is to get this to work through the script above that I have run into a wall.

Again, any help is appreciated. Thanks for your time.

DTS Migration To SSIS - Oracle Unsupport Data Type

Mar 18, 2008



OK I migrated a DTS package from MS SQL 2000 to MS SQL 2005 64-bit SSIS. OK so I fixed a problem with a Double Global Variable... Now I am stuck at a connection to Oracle and it returning data... Here is the error message:

[Execute SQL Task] Error: An error occurred while assigning a value to variable "Remedy_Count": "Unsupported data type on result set binding 0.".

My SQL Statement is this:

SELECT COUNT(*) AS Expr1
FROM DB.MYTABLE

When I run it from the Query Builder it returned this:

EXPR1 = 2983

Here are some details from the General Page on the Execute SQL Task

ResultSet - Single row
ConnectionType - OLE DB
Connection - Oracle Provider for OLE DB
SQLSourceType - Direct input
BypassPrepare - True

In the Result Set I have The following:

Result Name - Variable Name
0 - Remedy_Count

So... what can I do to fix this. I have the Remedy_Count set as a:

EvaluateAsExpression - False
Value - 2414
ValueType - Double

I have tried setting the ValueType to Object and other things... Same error... I read some where about how SSIS has issues when Oracle returns a Numeric type data. Can someone help me with this? Anything you all can tell me would be great.

Is Ssis The Only Technology That Can Read/write Raw Data Type Files?

Sep 21, 2007

I'm contemplating a sql server archive strategy that rolls really old data off any sort of dbms and onto low cost media like dvds in a non relational archive format. I dont want to ever worry about these archives spanning different versions of sql when i go to retrieve a range of data that happens to span sql versions (eg one disc was sourced from 2005 another by 2008 but my report needs a union of both).

So I'm thinking about neutral/efficient formats for these archives and a live homegrown catalog that can determine exactly what disc(s) need to be mounted based on passed from and to date parameters...all so that the data that might span discs (and versions and maybe even schemas) can be merged and loaded into my sql version d'jour's "throw away" archive database for a one time report or other unplanned activity.

I remember raw data types being very convenient as an ETL format for our customers who have ssis, but wouldn't want our sqlexpress customers to be left without the archiving capability. Do the "things" that read and write raw data files really originate in some special T-SQL command that all sql editions can use, or is it strictly an ssis thing?

We have an SSIS package that reads in a tab delimited file and throughs the data into a SQL Server 2005 table. The package worked fine on the test files but when we recieved the production files we are getting the error message:

Invalid data for type "numeric".


Needless to say this is not very discriptive. I ran a trace on the DB durning the call and its doing a bulk insert

BULK INSERT [dbo].[FNIAllAppData]

WITH (DATAFILETYPE = 'DTS_Buffers', CODEPAGE = 'RAW', CHECK_CONSTRAINTS, TABLOCK)


When I changed the Data Flow Destination off to OLE DB Destination the error does not occure and all records are loaded successfully.

2. Using a Data conversion box in Data flow transformation.

Any difference between these two? Which one should be used?

SSIS Custom Data Flow Component - Variable Type Converter

Jun 27, 2007

Hi all,



I am creating a customer data flow component for SSIS for use in a package. I've got some custom properties that I am exposing using the supplied advanced editor (no custom property editor here).



Some of my properties are enumerated types, and I have deciphered how to get those properties to show as dropdown lists of their respective enumerations. (For those of you who may be looking as hard as I did as to how to accomplish this, see the end of this post.)



I also have a few properties which request SSIS package variable names - such as an file name variable. However, I can't figure out how to tell the advanced editor that the property is looking for an SSIS variable, so that it can show a dropdown list of package variables, much like virtually any other Microsoft supplied Data Flow component can.



Is there a Type Converter I could specify for those custom properties? Is there another way to instruct SSIS that my custom property is expecting a variable? Or do I need to code a custom UI for editing my Data Flow Task?



To create a dropdown list of values for a custom property that represents an enum, do the following:

1. Create your enum definition, such as "public enum ThisIsMyEnum { one, two }"

2. Create a new class that inherits from TypeConverter, such as "public class MyEnumConverter : TypeConverter"

3. Override "CanConvertFrom", and return true if "sourceType == typeof(string)"

4. Override "CanConvertTo", and return true if "destinationType == typeof(string)"

5. Override "ConvertFrom", and return the enum value (such as "one" or "two" in my example) that corresponds to the string passed in the parameter "value"

6. Override "ConvertTo", and return a string that corresponds to the enum value passed in the parameter "value"

7. Override "GetStandardValuesSupported" and return true

8. Override "GetStandarValuesExclusive" and return true to indicate that ONLY the enum values should be accepted

9. Override "GetStandardValues", and return a new StandardValuesCollection constructed with Enum.GetValues() of your enum, such as "return new StandardValuesCollection(Enum.GetValues(typeof(ThisIsMyEnum)));"

10. Just above your "public enum" declaration, add a "TypeConverter" attribute to link your type converter to your enum, such as "[TypeConverter(typeof(MyEnumConverter))]"

11. In "ProvideComponentProperties", after you've created your custom property like this: "IDTSCustomProperty90 propEnum = ComponentMetaData.CustomPropertyCollection.New()", add another line to specify the TypeConverter property of the property to the full assembly name of your type converter, like so: "propEnum.TypeConverter = typeof(MyEnumConverter).AssemblyQualifiedName;"
