Constructor for a DropSequenceNode

Parameters:

dropSequenceName - The name of the sequence being dropped

cm - The context manager

Throws:

StandardException

Method Details

statementToString

public String statementToString()

Specified by:

statementToString in class StatementNode

bindStatement

public void bindStatement()
                   throws StandardException

Bind this DropSequenceNode.

Overrides:

bindStatement in class StatementNode

Throws:

StandardException - Thrown on error

makeConstantAction

public ConstantAction makeConstantAction()
                                  throws StandardException

Create the Constant information that will drive the guts of Execution.

Overrides:

makeConstantAction in class QueryTreeNode

Throws:

StandardException - Thrown on failure

acceptChildren

void acceptChildren(Visitor v)
             throws StandardException

Description copied from class: QueryTreeNode

Accept a visitor on all child nodes. All sub-classes that add fields that should be visited, should override this method and call accept(v) on all visitable fields, as well as super.acceptChildren(v) to make sure all visitable fields defined by the super-class are accepted too.

Overrides:

acceptChildren in class DDLStatementNode

Parameters:

v - the visitor

Throws:

StandardException - on errors raised by the visitor
