Crate datafusion::sql::sqlparser

SQL Parser for Rust

This crate provides an ANSI:SQL 2011 lexer and parser that can parse SQL into an Abstract Syntax Tree (AST). See the sqlparser crates.io page for more information.

For more information:

1. Parser::parse_sql and Parser::new for the Parsing API
2. ast for the AST structure
3. Dialect for supported SQL dialects

Example

use sqlparser::dialect::GenericDialect;
use sqlparser::parser::Parser;

let dialect = GenericDialect {}; // or AnsiDialect

let sql = "SELECT a, b, 123, myfunc(b) \
           FROM table_1 \
           WHERE a > b AND b < 100 \
           ORDER BY a DESC, b";

let ast = Parser::parse_sql(&dialect, sql).unwrap();

println!("AST: {:?}", ast);
