TppDBPipeline MasterFieldLinks

rbuser

From Rbuilder help files
"
property MasterDataPipeline: TppDataPipeline;

For the DBPipeline and BDEPipeline classes this property is informational
only and does not trigger any automatic record filtering logic
"

The same could be applied on MasterFieldLinks, couldn't it ?

You can use the MasterFieldLinks property if you are using pipelines on a
form and would like to avoid using Delphi's implementation of master-detail
linking. We have an example project which is downloadable:
http://www.digital-metaphors.com/tips/MagicMasterDetail.zip


When utilizing JIT or Text data pipelines in a master/detail relation, this
component holds the field relations used to connect the pipelines. It is
used in conjunction with the MasterDataPipeline property.
Used when manually linking datasets or text pipelines. MasterFieldLinks is
sometimes faster than linking standard Delphi TQuery objects. When accessing
TQuery objects, all detail queries must include all ORDER BY fields from the
master. Note: MasterFieldLinks was originally created to support text
pipeline linking and was later enhanced to support linked query dataviews in
DADE. This is the reason for the special ORDER BY clause requirements.
