resolveProceduralCommand

public abstract void resolveProceduralCommand(Command command,
                                              TempMetadataAdapter metadata,
                                              AnalysisRecord analysis)
                                       throws QueryMetadataException,
                                              QueryResolverException,
                                              TeiidComponentException

Throws:

QueryMetadataException

QueryResolverException

TeiidComponentException

expandCommand

public Command expandCommand(ProcedureContainer procCommand,
                             QueryMetadataInterface metadata,
                             AnalysisRecord analysis)
                      throws QueryMetadataException,
                             QueryResolverException,
                             TeiidComponentException

Expand a command by finding and attaching all subcommands to the command. If some initial resolution must be done for this to be accomplished, that is ok, but it should be kept to a minimum.

Parameters:

command - The command to expand

useMetadataCommands - True if resolver should use metadata commands to completely resolve

metadata - Metadata access

analysis - The analysis record that will be filled in if doing annotation.

Throws:

QueryMetadataException - If there is a metadata problem

QueryResolverException - If the query cannot be resolved

TeiidComponentException - If there is an internal error

getPlan

protected abstract java.lang.String getPlan(QueryMetadataInterface metadata,
                                            GroupSymbol group)
                                     throws TeiidComponentException,
                                            QueryMetadataException

For a given resolver, this returns the unparsed command.

Parameters:

metadata -

group -

Returns:

Throws:

TeiidComponentException

QueryMetadataException

findChildCommandMetadata

public GroupContext findChildCommandMetadata(ProcedureContainer container,
                                             TempMetadataStore discoveredMetadata,
                                             QueryMetadataInterface metadata)
                                      throws QueryMetadataException,
                                             QueryResolverException,
                                             TeiidComponentException

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

Parameters:

metadata - Metadata access

command - The command to find metadata on

childMetadata - The store to collect child metadata in

Throws:

QueryMetadataException - If there is a metadata problem

QueryResolverException - If the query cannot be resolved

TeiidComponentException - If there is an internal error

resolveCommand

                           TempMetadataAdapter metadata,
                           AnalysisRecord analysis,
                           boolean resolveNullLiterals)
                    throws QueryMetadataException,
                           QueryResolverException,
                           TeiidComponentException

Description copied from interface: CommandResolver

Resolve the command using the metadata.

Specified by:

resolveCommand in interface CommandResolver

Parameters:

command - The command to resolve
