Class CommandInstruction

java.lang.Object
  com.metamatrix.query.processor.program.ProgramInstruction
      com.metamatrix.query.processor.proc.CommandInstruction

All Implemented Interfaces:

Describable, java.lang.Cloneable

Direct Known Subclasses:

AbstractAssignmentInstruction, CreateCursorResultSetInstruction, ExecDynamicSqlInstruction, ExecSqlInstruction

public abstract class CommandInstruction
extends ProgramInstruction

This abstract base class has common methods for dealing with instructions that have commands. In particular commands may have nested EXECs that have parameter references, which require some special handling.
