LuaSql for GopherLua

A native Go implementation of SQL client for the GopherLua VM.

Using

Loading Modules

import (
	"github.com/tengattack/gluasql"
)

// Bring up a GopherLua VM
L := lua.NewState()
defer L.Close()

// Preload LuaSql modules
gluasql.Preload(L)

Or if we only need mysql module:

import (
	mysql "github.com/tengattack/gluasql/mysql"
)

// Bring up a GopherLua VM
L := lua.NewState()
defer L.Close()

L.PreloadModule("mysql", mysql.Loader)

MySQL

mysql = require('mysql')
c = mysql.new()
ok, err = c:connect({ host = '127.0.0.1', port = 3306, database = 'test', user = 'user', password = 'pass' })
if ok then
  res, err = c:query('SELECT * FROM mytable LIMIT 2')
  dump(res)
end

PostgreSQL

import lib/pq first:

import (
	_ "github.com/lib/pq"
)

mysql = require('mysql')
c = mysql.new()
ok, err = c:connect('postgres://host=127.0.0.1 port=5432 user=user password=123456 dbname=foo sslmode=disable')
if ok then
  res, err = c:query('SELECT * FROM mytable LIMIT 2')
  dump(res)
end

SQLite

Since it depends go-sqlite3, we need gcc to compile SQLite module, more details: https://github.com/mattn/go-sqlite3

sqlite3 = require('sqlite3')
c = sqlite3.new()
ok, err = c:open('test.db', { cache = 'shared' })
if ok then
  res, err = c:query('SELECT * FROM mytable LIMIT 2')
  dump(res)
end
