Article

Obsolete. Use the managed client object model to perform queries against SharePoint Foundation site and list data, instead. This Web service is an adapter service that provides a method for performing queries, and it is maintained for backward compatibility.

Remarks

SharePoint Foundation does not support date-time values in XSD format, so time is ignored when the Query method is used.

The following table describes properties on the list or site object that is returned.

Name	Description
comparisonLocale	Optional. Specifies the default Windows locale identifier for a RowReturning object. This attribute is not defined for non-RowReturning objects.
contentType	Required. Specifies the content type of the object returned, which is always set to RowReturning for list objects and to TableReturning for site objects.
displayName	Optional. Specifies a string containing the friendly name for the list or site object. This property is always returned.
id	Required. A string that identifies the list or site object.
querySupport	Optional. Only the data retrieval service query (DSPQ) is supported.
serverParameters	Required. Always none for list and site objects.
SupportFiltering	Optional. Specifies whether filtering is supported. Always true for RowReturning objects. Although false for non-RowReturning objects, the unsafe and serverParameters fields can still be filtered.
SupportOrdering	Optional. Specifies whether ordering is supported. Always true.
supportPaging	Optional. The adapter supports forward-only paging as defined in data retrieval service protocol. When paging is requested in the query by specifying startPosition="" within the <dsQuery> element, the adapter generates an XML BLOB that can be used to retrieve the next batch of rows. This XML BLOB is returned through the next attribute in the <dsQueryResponse> element returned. The client can then set the startPosition attribute to this BLOB and repeat the original query to retrieve the next set of rows.
unsafe	Optional. Because all site and list objects are safe, this attribute is always set to false.

Examples

The following code example uses the Query method to return items from a SharePoint list in which the Author column contains a specified name and the Number column contains values greater than a specified value.

Dim myStsAd As New Web_Reference_Name.StsAdapter()
myStsAd.Credentials = System.Net.CredentialCache.DefaultCredentials

Dim vArray(0) As String
vArray(0) = "1.0"

reqHeader.document = Web_Reference_Name.DocumentType.content
reqHeader.method = Web_Reference_Name.MethodType.query
