@florajs/sql-parser
Parse simple SQL statements into an abstract syntax tree (AST) and convert it back to SQL.
Usage
Create AST for SQL statement
const { Parser } = require('@florajs/sql-parser');
const parser = new Parser();
const ast = parser.parse('SELECT * FROM t');
console.log(ast);Convert AST back to SQL
const { Parser } = require('@florajs/sql-parser');
const ast = (new Parser()).parse('SELECT * FROM t');
const toSQL = require('@florajs/sql-parser').util.astToSQL;
console.log(toSQL(ast));The generated SQL is ANSI SQL compliant. To run those queries on MySQL, make sure you set correct SQL mode
SET SESSION sql_mode = 'ANSI';before running any query.
