包路径：org.apache.calcite.sql.SqlNode
类名称：SqlNode
方法名：validate
SqlNode.validate介绍
[英]Validates this node.
The typical implementation of this method will make a callback to the validator appropriate to the node type and context. The validator has methods such as SqlValidator#validateLiteral for these purposes.
[中]验证此节点。
此方法的典型实现将根据节点类型和上下文对验证器进行回调。出于这些目的，验证器有一些方法，比如SqlValidator#validateLiteral。
