Struct SqlParser 

pub struct SqlParser { /* private fields */ }

SQL 解析器（基于 Tree-sitter）

Implementations

impl SqlParser

pub fn new() -> Self

创建 SQL 解析器

pub fn parse(&mut self, sql: &str) -> ParseResult

解析 SQL 语句

pub fn tokenize(&self, tree: &Tree, source: &str) -> Vec<Token>

提取所有 Token（参考 sqls 的 tokenizer）

pub fn get_node_at_position<'a>( &self, tree: &'a Tree, position: Position, ) -> Option<Node<'a>>

获取指定位置的节点

pub fn extract_tables(&self, tree: &Tree, source: &str) -> Vec<String>

提取查询中的表名

pub fn is_in_from_context(&self, node: Node<'_>, source: &str) -> bool

检查节点是否在 FROM/JOIN 上下文中

pub fn extract_columns(&self, tree: &Tree, source: &str) -> Vec<String>

提取查询中的列名

pub fn is_in_column_context(&self, node: Node<'_>, source: &str) -> bool

检查节点是否在列上下文中（SELECT/WHERE/ORDER BY 等）

pub fn node_text(&self, node: Node<'_>, source: &str) -> String

获取节点的文本内容

pub fn node_range(&self, node: Node<'_>) -> Range

获取节点的范围

pub fn analyze_completion_context( &self, node: Node<'_>, source: &str, _position: Position, ) -> CompletionContext

分析补全上下文 (Text-based heuristics for reliability) 分析补全上下文 (AST-based) Uses Tree-sitter AST node traversal for robust context detection

pub fn get_table_name_for_column( &self, node: Node<'_>, source: &str, ) -> Option<String>

获取表名（用于 TableColumn 上下文） 如果光标在 table.column 的位置，返回表名

impl SqlParser

pub fn extract_aliases( &self, _tree: &Tree, source: &str, ) -> HashMap<String, String>

提取表别名映射 (Alias -> Table Name) Uses text-based extraction for reliability

pub fn extract_referenced_tables( &self, _tree: &Tree, source: &str, ) -> Vec<String>

提取SQL中引用的表名（从FROM和JOIN子句）

pub fn node_to_ast_node(&self, node: Node<'_>, source: &str) -> AstNode

将 Tree-sitter Node 转换为 AstNode

Trait Implementations

impl Default for SqlParser

fn default() -> Self

Returns the “default value” for a type.
