  dataType - Exact numeric type of the new sequence

  initialValue - Starting value

  stepValue - Increment amount

  maxValue - Largest value returned by the sequence generator

  minValue - Smallest value returned by the sequence generator

Method Detail

• toString

  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

• bindStatement

  public void bindStatement()
                     throws StandardException

  Bind this CreateSequenceNode. The main objectives of this method are to resolve the schema name, determine privilege checks, and vet the variables in the CREATE SEQUENCE statement.

  Overrides:

  bindStatement in class StatementNode

  Throws:

  StandardException - Thrown on error

• statementToString

  public java.lang.String statementToString()

  Specified by:

  statementToString in class StatementNode

• makeConstantAction

  public ConstantAction makeConstantAction()

  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
