Constructor Detail

CreateCursorResultSetInstruction

public CreateCursorResultSetInstruction(java.lang.String rsName,
                                        ProcessorPlan plan)

Method Detail

process

public void process(ProcedurePlan procEnv)
             throws BlockedException,
                    TeiidComponentException,
                    TeiidProcessingException

If the result set named rsName does not exist yet in the ProcedurePlan, then this instruction will define that result set. It will then throw a BlockedException if this result set is selecting from other than temp groups (because those results will be delivered asynchronously). IF the result set named rsName does already exist, this instruction will just increment the program counter and do nothing else.

Specified by:

process in class ProgramInstruction

Throws:

BlockedException - if this result set is not selecting from only temp groups

TeiidComponentException

TeiidProcessingException

clone
