## Install
```sh
$ npm install mysql
```
For information about the previous 0.9.x releases, visit the [v0.9 branch][].
Sometimes I may also ask you to install the latest version from Github to check
if a bugfix is working. In this case, please do:
```sh
$ npm install mysqljs/mysql
```
[v0.9 branch]: https://github.com/mysqljs/mysql/tree/v0.9
## Introduction
This is a node.js driver for mysql. It is written in JavaScript, does not
require compiling, and is 100% MIT licensed.
Here is an example on how to use it:
```js
var mysql = require('mysql');
var connection = mysql.createConnection({
host : 'localhost',
user : 'me',
password : 'secret',
database : 'my_db'
});
connection.connect();
connection.query('SELECT 1 + 1 AS solution', function(err, rows, fields) {
if (err) throw err;
console.log('The solution is: ', rows[0].solution);
});
connection.end();
```
From this example, you can learn the following:
* Every method you invoke on a connection is queued and executed in sequence.
* Closing the connection is done using `end()` which makes sure all remaining
queries are executed before sending a quit packet to the mysql server.

including the term `mysql`)
## Establishing connections
The recommended way to establish a connection is this:
```js
var mysql = require('mysql');
var connection = mysql.createConnection({
host : 'example.org',
user : 'bob',
password : 'secret'
});
connection.connect(function(err) {
if (err) {
console.error('error connecting: ' + err.stack);
return;
}
console.log('connected as id ' + connection.threadId);
});
```
However, a connection can also be implicitly established by invoking a query:
```js
var mysql = require('mysql');
var connection = mysql.createConnection(...);
connection.query('SELECT 1', function(err, rows) {
// connected! (unless `err` is set)
});
```
Depending on how you like to handle your errors, either method may be
appropriate. Any type of connection error (handshake or network) is considered
a fatal error, see the [Error Handling](#error-handling) section for more
information.
## Connection options
When establishing a connection, you can set the following options:
* `host`: The hostname of the database you are connecting to. (Default:
`localhost`)
* `port`: The port number to connect to. (Default: `3306`)
* `localAddress`: The source IP address to use for TCP connection. (Optional)
* `socketPath`: The path to a unix domain socket to connect to. When used `host`
and `port` are ignored.
* `user`: The MySQL user to authenticate as.
* `password`: The password of that MySQL user.
* `database`: Name of the database to use for this connection (Optional).
* `charset`: The charset for the connection. This is called "collation" in the SQL-level
of MySQL (like `utf8_general_ci`). If a SQL-level charset is specified (like `utf8mb4`)
then the default collation for that charset is used. (Default: `'UTF8_GENERAL_CI'`)
* `timezone`: The timezone used to store local dates. (Default: `'local'`)
* `connectTimeout`: The milliseconds before a timeout occurs during the initial connection
to the MySQL server. (Default: `10000`)
* `stringifyObjects`: Stringify objects instead of converting to values. See
issue [#501](https://github.com/mysqljs/mysql/issues/501). (Default: `false`)
* `insecureAuth`: Allow connecting to MySQL instances that ask for the old
(insecure) authentication method. (Default: `false`)
* `typeCast`: Determines if column values should be converted to native
JavaScript types. (Default: `true`)
* `queryFormat`: A custom query format function. See [Custom format](#custom-format).
* `supportBigNumbers`: When dealing with big numbers (BIGINT and DECIMAL columns) in the database,
you should enable this option (Default: `false`).
* `bigNumberStrings`: Enabling both `supportBigNumbers` and `bigNumberStrings` forces big numbers
(BIGINT and DECIMAL columns) to be always returned as JavaScript String objects (Default: `false`).
Enabling `supportBigNumbers` but leaving `bigNumberStrings` disabled will return big numbers as String
objects only when they cannot be accurately represented with [JavaScript Number objects] (http://ecma262-5.com/ELS5_HTML.htm#Section_8.5)
(which happens when they exceed the [-2^53, +2^53] range), otherwise they will be returned as
Number objects. This option is ignored
