PROTECTED CommitChanges (handle)
Overrides Consultingwerk.SmartFramework.SmartDataAccess:CommitChanges (handle)
Purpose: This method is called from SaveChanges in the DA
to do the actual database commit and any transaction-related
validation logic for a buffer.
Notes: This is taken directly from the OERI.
- Note that in this sample that illustrates support for distributed
business logic the DA saves the whole dataset in SaveChanges, so
this is not currently called from the BE.
- The event names are the same as in the OERI. The word "Trans"
is somewhat misleading as the DA need to support large transactions.
One could consider using a name that indicates that this is a row
event instead.

Parameters:
phBuffer HANDLE
The handle of the after buffer to commit

The query handle to reposition backwards
piNumRecords INTEGER
The number of records
Top

needs to start on a backwards fill operation
Notes: This method may be overridden in a DataAccess object class
This method is no longer used for the backwards batching.

PROTECTED SaveBuffer (handle)
Inherited from Consultingwerk.OERA.DataAccess
Purpose: Called from saveChanges to process changes
for a single DataSet temp-table buffer.
Notes: This is similar to the OERI BE version, but has no pre and
post transaction hooks because:
- This method might very well be called inside a transaction.
- The BE supports hooks outside of the transaction scope.

Parameters:
phBuffer HANDLE
The handle of the after buffer
Top

PUBLIC SaveChanges ()
Overrides Consultingwerk.OERA.DataAccess:SaveChanges ()
Purpose: Save changes to physical storage
Notes: This implementation of data access save traverses all records in order
to:
- Allow the DA to control transactions, which cannot be directly
controlled in distributed BL. Transaction control is a concern of
the BL, but should not be contolled with TRANSACTION keyword.
- Offer a course grained save interface from distributed BL
- The default operation here is just a transaction per record
- This simple sample does not use child relations to traverse
the buffers as the OERI BE example. (A property that controls
update order would give the same effect).
- Traversing of child data from a parent would make sense if done for
one parent record at a time.

Top

PROTECTED SuggestDataSourceIndex (handle, character)
Inherited from Consultingwerk.OERA.DataAccess
Purpose: Method allows enforcing specific indexes when populating child record
of a data-relation. When the parent buffer and the child buffer are
FILL'ed during the ProDataset:FILL() operation, we ensure the given index
Notes: Allows to avoid situations where in a Order -> OrderLine data-relation
when filtered by Orderline.ItemNum the itemnum index is choosen instead
of the more efficient orderline index (both indexes provide one equality
match, but itemnum is the alphabetically first index)
This method should be called from the dataset's BEFORE-FILL call back

that the proper join criteria between the data-source query buffers
is specified in the SourceDefaultQuery
