Method Details

statementToString

String statementToString()

Specified by:

statementToString in class StatementNode

bindStatement

public void bindStatement()
                   throws StandardException

Bind this DropIndexNode. This means looking up the index, verifying it exists and getting the conglomerate number.

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
