                                             TeiidComponentException

Description copied from class: ProcedureContainerResolver

Find all metadata defined by this command for it's children. This metadata should be collected in the childMetadata object. Typical uses of this are for stored queries that define parameter variables valid in subcommands. only used for inserts, updates, and deletes

Overrides:

findChildCommandMetadata in class ProcedureContainerResolver

metadata - Metadata access

Throws:

QueryMetadataException - If there is a metadata problem

QueryResolverException - If the query cannot be resolved

TeiidComponentException - If there is an internal error
