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
Adobe ColdFusion 11+
Lucee 4.5+
qb supports four major database grammars:
MSSQL (MSSQLGrammar)
MySQL (MySQLGrammar)
Oracle (OracleGrammar)
Installation is easy through and . Simply type box install qb to get started.
Compare these two examples:
The differences become even more stark when we introduce more complexity:
With qb you can easily handle setting order by statements before the columns you want or join statements after a where clause:
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!
To start a new query, instantiate a new Builder: wirebox.getInstance('QueryBuilder@qb').
By default, qb uses a generic Grammar. You can specify your specific grammar in ColdBox by setting the defaultGrammar in your moduleSettings.
If you are not using WireBox, just make sure to wire up the Builder object with the correct grammar:
You can influence the return format of the result in two ways.
By default, qb returns an array of structs as the result of your query. You can turn this behavior off by setting builder.setReturningArrays( false ) for one-offs or setting returningArrays = false in your ColdBox config.
If you want complete control over your return result, you can provide a closure as a returnFormat. The results of the closure will be returned as the results of the builder.
Two interception points are available from QB: preQBExecute and postQBExecute. These fire before and after the queryExecute call, respectively. The following information is available in the interceptData struct:

// Plain old CFML
q = queryExecute("SELECT * FROM users");
// qb
query = wirebox.getInstance('QueryBuilder@qb');
q = query.from('users').get();// 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('QueryBuilder@qb');
q = query.from('posts')
.whereNotNull('published_at')
.whereIn('author_id', [5, 10, 27])
.get();query = wirebox.getInstance('QueryBuilder@qb');
