resolveProceduralCommand

public abstract void resolveProceduralCommand(Command command,
                                              TempMetadataAdapter metadata)

                                              TeiidComponentException

Throws:

QueryMetadataException

QueryResolverException

TeiidComponentException

expandCommand

public Command expandCommand(ProcedureContainer procCommand,
                             QueryMetadataInterface metadata,
                             AnalysisRecord analysis)

                             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:

procCommand - The command to expand

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 String getPlan(QueryMetadataInterface metadata,
                                  GroupSymbol group)
                           throws TeiidComponentException,
                                  QueryMetadataException,
                                  QueryResolverException

For a given resolver, this returns the unparsed command.

Parameters:

metadata -

group -

Returns:

Throws:

TeiidComponentException

QueryMetadataException

QueryResolverException

Specified by:

resolveCommand in interface CommandResolver

Parameters:

metadata - Metadata

resolveNullLiterals - true if the resolver should consider replacing null literals with more appropriate types

Throws:

QueryMetadataException - If there is a metadata problem

QueryResolverException - If the query cannot be resolved

TeiidComponentException - If there is an internal error
