acceptChildrenback to summary
pack-priv void acceptChildren(Visitor v) throws StandardException

Overrides org.apache.derby.impl.sql.compile.DDLStatementNode.acceptChildren.

Doc from org.apache.derby.impl.sql.compile.QueryTreeNode.acceptChildren.

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.

Parameters
v:Visitor

the visitor

bindStatementback to summary
public void bindStatement() throws StandardException

Overrides org.apache.derby.impl.sql.compile.StatementNode.bindStatement.

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.
