Using The Rdbmsresolver Component - MACROMEDIA FLASH 8-COMPONENTS LANGUAGE Reference

CHAPTER 37
RDBMSResolver component (Flash
Professional only)
Resolver components are used with the DataSet component (part of the data management
functionality in the Flash data architecture) to save changes to an external data source.
Resolvers include both the RDBMSResolver component and the XUpdateResolver
component. Resolvers take a delta packet (returned by
to an update packet in a format appropriate to the type of resolver. The update packet can
then be transmitted to the external data source by one of the connector components. Resolver
components have no visual appearance at runtime.
The RDBMSResolver component creates an XML update packet that can be easily parsed
into SQL statements for updating a relational database. The RDBMSResolver component is
connected to the
DeltaPacket
packet to a connector, receives server errors back from the connector, and communicates them
back to the DataSet component—all using bindable properties.
For more information about the Flash data architecture, see "Data resolution (Flash
Professional only)" in Using Flash. For more information about relational databases, see
"Resolving data to a relational database (Flash Professional only)" in Using Flash. For a
complete example of an application that updates data using the RDBMSResolver component,
see www.macromedia.com/devnet/mx/flash/articles/delta_packet.html.
You can use the RDBMSResolver component to send data updates to any object you
write that can parse XML and generate SQL statements against a database—for
example, an ASP page, a Java servlet, or a ColdFusion component.
