  public java.lang.String toString()

  Convert this object to a String. See comments in QueryTreeNode.java for how this should be done for tree printing.

  Overrides:

  toString in class DDLStatementNode

  Returns:

  This object as a String

• statementToString

  java.lang.String statementToString()

  Specified by:

  statementToString in class StatementNode

• printSubNodes

  void printSubNodes​(int depth)

  Prints the sub-nodes of this object. See QueryTreeNode.java for how tree printing is supposed to work.

  Overrides:

  printSubNodes in class QueryTreeNode

  Parameters:

  depth - The depth of this node in the tree

• bindStatement

  public void bindStatement()
                     throws StandardException

  Overrides:

  bindStatement in class StatementNode

  Throws:

  StandardException - Thrown on error

• bindViewDefinition

  private ProviderInfo[] bindViewDefinition​(DataDictionary dataDictionary,
