pack-priv void acceptChildren(Visitor v) throws StandardException

Overrides org.apache.derby.impl.sql.compile.QueryTreeNode.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.

Doc from org.apache.derby.impl.sql.compile.StatementNode.bindStatement.

Perform the binding operation statement. Binding consists of permissions checking, view resolution, datatype resolution, and creation of a dependency list (for determining whether a tree or plan is still up to date). This bindStatement() method does nothing. Each StatementNode type that can appear at the top of a tree can override this method with its own bindStatement() method that does "something".
