B.3 diffgr Namespace
The diffgr namespace contains XML attributes used to mark up a DiffGram document with versioning information. Here's how the diffgr namespace is imported in a DiffGram document:
<xs:schema id="DataSetName" xmlns=""
xmlns:msdata="urn:schemas-microsoft-com:xml-msdata"
xmlns:diffgr="urn:schemas-microsoft-com:xml-diffgram-v1"
xmlns:xsd="http://www.w3.org/2001/XMLSchema" >
The diffgr namespace includes several attributes that can be applied to row elements, as described in Table B-9. The values hasChanges can take on are listed in Table B-10.
|
Attribute |
Description |
|---|---|
id |
Uniquely identifies a row. This pairs the elements in the <diffgr:before> and <diffgr:errors> sections to the current data. This value is generated using the table name and row identifier (for example, diffgr:id="Customers1"). |
parentId |
Used with relationships. Identifies the element that's the parent for the current row, using the parent's diffgr:id attribute. |
hasChanges |
Flags a row, identifying that is has been modified. This attribute is used only in the <DataInstance> section and can take one of the three values described in Table B-10. |
hasErrors |
If set to true, the row is flagged as having an error (which is described in the <diffgr:errors> section). |
Error |
Contains the text of the DataRow.RowError property. This is used only in the <diffgr:errors> section. |
|
Attribute |
Description |
|---|---|
Inserted |
Represents a newly added row. |
modified |
Represents a row in which at least some data has changed from the data in the <diffgr:before> section. This doesn't include the deleted row, which appears in the <diffgr:before> section but nowhere else. |
descent |
Identifies an element in which one or more children from a parent-child relationship have been modified. |
