sql string builder for node

Let's be honest - hand generating SQL is no fun, especially in a language which has clumsy support for multi-line strings.

But SQL is so good. We need SQL. So let's save the day and generate it with a jQuery-esque fluent interface.

Maybe it's still not fun, but at least it's less not fun. That's at least worth a participation award.

examples

//require the module
var sql = require('sql');

//first we define our tables
var user = sql.define({
  name: 'user',
  columns: ['id', 'email', 'lastLogin']
});

var post = sql.define({
  name: 'post',
  columns: ['id', 'userId', 'date', 'title', 'body']
})

//now let's make a simple query
var query = user.select(user.star()).from(user).toQuery();
console.log(query.text); //SELECT "user".* FROM "user"

//something more interesting
var query = user
    .select(user.id)
    .from(user)
    .where(
      user.name.equals('boom').and(user.id.equals(1))
    ).or(
      user.name.equals('bang').and(user.id.equals(2))
    ).toQuery();
    
//query is parameterized by default
console.log(query.text); //SELECT "user"."id" FROM "user" WHERE ((("user"."name" = $1) AND ("user"."id" = $2)) OR (("user"."name" = $3) AND ("user"."id" = $4)))

console.log(query.values); //['boom', 1, 'bang', 2]


//how about a join?
var query = user.select(user.name, post.content)
  .from(user.join(post).on(user.id.equals(post.userId))).toQuery();
  
console.log(query.text); //'SELECT "user"."name", "post"."content" FROM "user" INNER JOIN "post" ON ("user"."id" = "post"."userId")'

There are a lot more examples under test/dialect-tests.js

contributing

I love contributions. If I could, I would write love 500 times, but that would be readme bloat.

Still, that's how much I love them. Let's work together on this.

If you want to contribute here's what you do:

1. fork the repo
2. git pull https://github.com/(your_username)/node-sql
3. cd node-sql
4. npm install
5. npm test

At this point the tests should pass for you. If they don't pass please open an issue with the output or you can even send me an email directly. My email address is on my github profile and also on every commit I contributed in the repo.

Once the tests are passing, modify as you see fit. Please make sure you write tests to cover your modifications. Once you're ready, commit your changes and submit a pull request.

As long as your pull request doesn't have completely off-the-wall changes and it does have tests I will almost always merge it right away and push it to npm

If you think your changes are too off-the-wall, open an issue or a pull-request without code so we can discuss them.

Seriously:

your contributions >= my contributions

I definitely need help with mysql and sqlite syntax. I'm not very familiar...so that's always a good place to start.
