All Implemented Interfaces:

Visitable
```
class NOPStatementNode
extends StatementNode
```
A NOPStatement node is for statements that don't do anything. At the time of this writing, the only statements that use it are SET DB2J_DEBUG ON and SET DB2J_DEBUG OFF. Both of these are executed in the parser, so the statements don't do anything at execution

- Method Detail
  - statementToString
```
java.lang.String statementToString()

    Specified by:
    
    statementToString in class StatementNode
  - bindStatement
```
public void bindStatement()
                   throws StandardException
```
    Bind this NOP statement. This throws an exception, because NOP statements by definition stop after parsing.
    
    Overrides:
    
    bindStatement in class StatementNode
    
    Throws:
    
    StandardException - Always thrown to stop after parsing
  - activationKind
```
int activationKind()
```
    Specified by:
    
    activationKind in class StatementNode
