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
