Introduction
qb is a fluent query builder for CFML. It is heavily inspired by Eloquent from Laravel.
Using qb, you can:
Quickly scaffold simple queries
Make complex, out-of-order queries possible
Abstract away differences between database engines
Requirements
Adobe ColdFusion 2016+
Lucee 5+
qb supports four major database grammars:
MySQL (MySQLGrammar)
Oracle (OracleGrammar)
Postgres (PostgresGrammar)
Microsoft SQL Server (SqlServerGrammar)

Installation
Installation is easy through CommandBox and ForgeBox. Simply type box install qb to get started.
Code Samples
Compare these two examples:
// Plain old CFML
q = queryExecute("SELECT * FROM users");
​
// qb
query = wirebox.getInstance('[email protected]');
q = query.from('users').get();
The differences become even more stark when we introduce more complexity:
// Plain old CFML
q = queryExecute(
    "SELECT * FROM posts WHERE published_at IS NOT NULL AND author_id IN ?",
    [ { value = '5,10,27', cfsqltype = 'CF_SQL_NUMERIC', list = true } ]
);
​
// qb
query = wirebox.getInstance('[email protected]');
q = query.from('posts')
         .whereNotNull('published_at')
         .whereIn('author_id', [5, 10, 27])
         .get();
With qb you can easily handle setting order by statements before the columns you want or join statements after a where clause:
query = wirebox.getInstance('[email protected]');
q = query.from('posts')
         .orderBy('published_at')
         .select('post_id', 'author_id', 'title', 'body')
         .whereLike('author', 'Ja%')
         .join('authors', 'authors.id', '=', 'posts.author_id')
         .get();
​
// Becomes
​
q = queryExecute(
    "SELECT post_id, author_id, title, body FROM posts INNER JOIN authors ON authors.id = posts.author_id WHERE author LIKE ? ORDER BY published_at",
    [ { value = 'Ja%', cfsqltype = 'CF_SQL_VARCHAR', list = false, null = false } ]
);
qb enables you to explore new ways of organizing your code by letting you pass around a query builder object that will compile down to the right SQL without you having to keep track of the order, whitespace, or other SQL gotchas!
Here's a gist with an example of the powerful models you can create with this! https://gist.github.com/elpete/80d641b98025f16059f6476561d88202​
Usage
To start a new query, instantiate a new Builder: wirebox.getInstance('[email protected]').
By default, qb uses a generic Grammar. You can specify your specific grammar in ColdBox by setting the defaultGrammar in your moduleSettings.
moduleSettings = {
    qb = {
        defaultGrammar = "[email protected]"
    }
};
If you are not using WireBox, just make sure to wire up the Builder object with the correct grammar:
var grammar = new qb.models.Query.Grammars.MySQLGrammar();
var builder = new qb.models.Query.Builder( grammar );
