Querying SharePoint List from Reporting Services returns only “not null” columns

  • Article

 

Querying to a Sharepoint List from a report in Reporting Services 2005 returns only the columns that contain data. If any of the columns is NULL, they are not returned.

This behavior is due to the Auto derivation the XMLDP: When there is an empty value for the 1st row, the column is not displayed.

 

This is fixed for the next version of Reporting Services (Katmai). For the moment you can use the following workaround, specifying all the columns explicitly (@Column1,@Column2,@Column3,@Column4,@column5,@column6,@column7):

<Query>

    <Method Namespace="https://schemas.microsoft.com/sharepoint/soap/" Name="GetListItems">

        <Parameters>

            <Parameter Name="listName">

                <DefaultValue>SomeListName</DefaultValue>

            </Parameter>

            <Parameter Name="viewName">

                <DefaultValue>{d99b0402-38b9-48a5-87e9-2c6bf198a30c}</DefaultValue>

            </Parameter>

        </Parameters>

    </Method>

    <ElementPath IgnoreNamespaces="true">GetListItemsResponse/GetListItemsResult/listitems/data/row{@Column1,@Column2,@Column3,@Column4,@column5,@column6,@column7}</ElementPath>

    <SoapAction>https://schemas.microsoft.com/sharepoint/soap/GetListItems</SoapAction>

</Query>

    Has anyone figured out how to specify columns that have a space in the column name?  I've tried using underscore instead of space, wrapping the field in single quotes, wrapping the field in double quotes, wrapping the field in square brackets...all to no avail.

    Brilliant! you have resolved an issue i was facing. I found the easiest way obtain the column names was to use fiddler when querying the web service, i then extracted the internal names and formatted using the example above. If any one knows of a simpler way please let me know!

    Hi, I know that this is an old post. I've tried the Maria solution, but the empty fields aren't returned from Lists.asmx. I'm using Sharepoint 2010 with SQLServer 2012

    Worked for me Maria. Thanks! The column name has to be like @ows_FirstPartOfName + x0020 for space + SecondPartOfName and it works.
