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".
