tarantool / sqlparser

An SQL parser for Tarantool based on Hyrise

Tarantool SQL Parser

An SQL parser for LuaJIT. It takes an SQL string as an input and returns an AST. The project is based on Hyrise SQL parser. It uses FFI to communicate with it.

Requirements:

• gcc 5+ or clang 5+

Installation:

tarantoolctl rocks install sqlparser

Usage:

local parser = require("sqlparser")

local ast = parser.parse("select a from test;")

ast variable now contains:

{
    "parameters": [],
    "errorLine": 0,
    "statements": [
        {
            "fromTable": {
                "type": "table",
                "name": "test"
            },
            "selectList": [
                {
                    "type": "columnRef",
                    "name": "a"
                }
            ],
            "selectDistinct": false,
            "type": "select"
        }
    ],
    "isValid": true
}

And backwards:

local queries = parser.tostring(ast)

queries[1] is:

select "a" from "test";
