Inserting, Deleting, and Updating Features
To change data in a feature source, create an MgFeatureCommandCollection
object. This can contain commands to insert, delete, or update features in an
FDO data source. The commands are executed sequentially. For FDO providers
that support transaction processing, the commands can be treated as a single
transaction.
Feature commands can be one of the following:
■ MgDeleteFeatures
■ MgInsertFeatures
■ MgUpdateFeatures
To execute the commands, call MgFeatureService::UpdateFeatures(). The
feature class name and property names in any of the feature commands must
match the class name and property names in the feature source.
For example, to delete all features in a feature class with an identity property
ID, execute the following:
$commands = new MgFeatureCommandCollection();
$deleteCommand = new MgDeleteFeatures($className, "ID like '%'");
$commands->Add($deleteCommand);
$featureService->UpdateFeatures($featureSource, $commands, false);
To insert features, create an MgPropertyCollection object that contains the
properties of the new feature. Create an MgInsertFeatures object and add
this to the MgFeatureCommandCollection object.
For example, to add a new feature with a single geometry property, execute
the following:
