## Functions
System::Void | OSGeo::FDO::Commands::Schema::Execute ()
| Executes the ApplySchema command that creates metadata and physical storage for the schema. An exception is thrown if the schema already exists or if a schema already exists and the feature provider only supports a single schema. If schema changes include deletion of classes or the schema itself, then those classes (or the schema, if it is marked as deleted) must not contain any instance data. If they do, an exception will be thrown. Implementors must call FeatureSchema::AcceptChanges() when Execute() succeeds. It must be called after the schema has been successfully applied, in order to synchronize the states of the schema elements.
__property System::Void | OSGeo::FDO::Commands::Schema::set_SchemaName (System::String *value)
| Sets the name of the schema to describe. This function is optional; if not specified execution of the command will describe all schemas.
