CI-Node-query
A node query builder for various SQL databases, based on CodeIgniter's query builder.
Features
- Callback and Promise API for making database calls.
Supported adapters
- mysql
- mysql2
- pg
- dblite
- node-firebird (Not supported as of version 3.1.0, as the adapter is very difficult to test)
Installation
npm install ci-node-query
Basic use
var nodeQuery = require('ci-node-query');
var connection = ... // Database module connection
// Three arguments: database type, database connection, database connection library
var query = nodeQuery.init('mysql', connection, 'mysql2');
// The third argument is optional if the database connection library has the same name as the adapter, eg..
nodeQuery.init('mysql', connection, 'mysql');
// Can be instead
nodeQuery.init('mysql', connection);
// You can also retrieve the instance later
query = nodeQuery.getQuery();
query.select('foo')
.from('bar')
.where('x', 3)
.orWhere({y: 2})
.join('baz', 'baz.boo = bar.foo', 'left')
.orderBy('x', 'DESC')
.limit(2, 3)
.get(function(/* Adapter dependent arguments */) {
// Database module result handling
});
// As of version 3.1.0, you can also get promises
var queryPromise = query.select('foo')
.from('bar')
.where('x', 3)
.orWhere({y: 2})
.join('baz', 'baz.boo = bar.foo', 'left')
.orderBy('x', 'DESC')
.limit(2, 3)
.get();
queryPromise.then(function(res) {
// Handle query results
});
Security notes
As of version 2, where and having type methods parse the values passed to look for function calls. While values passed are still passed as query parameters, take care to avoid passing these kinds of methods unfiltered input. SQL function arguments are not currently parsed, so they need to be properly escaped for the current database.
