* Add `fields` argument to `query()` as well as `'fields'` event. This is
similar to what was available in 0.9.x.
* Support connecting to the sphinx searchd daemon as well as MariaDB (#199).
* Implement long stack trace support, will be removed / disabled if the node
core ever supports it natively.
* Implement `nestTables` option for queries, allows fetching JOIN result sets
with overlapping column names.
* Fix ? placeholder mechanism for values containing '?' characters (#205).
* Detect when `connect()` is called more than once on a connection and provide
the user with a good error message for it (#204).
* Switch to `UTF8_GENERAL_CI` (previously `UTF8_UNICODE_CI`) as the default
charset for all connections to avoid strange MySQL performance issues (#200),
and also make the charset user configurable.
* Fix BLOB type casting for `TINY_BLOB`, `MEDIUM_BLOB` and `LONG_BLOB`.
* Add support for sending and receiving large (> 16 MB) packets.
## v2.0.0-alpha (2012-05-15)
This release is a rewrite. You should carefully test your application after
upgrading to avoid problems. This release features many improvements, most
importantly:
* ~5x faster than v0.9.x for parsing query results
* Support for pause() / resume() (for streaming rows)
* Support for multiple statement queries
* Support for stored procedures
* Support for transactions
* Support for binary columns (as blobs)
* Consistent & well documented error handling
* A new Connection class that has well defined semantics (unlike the old Client class).
* Convenient escaping of objects / arrays that allows for simpler query construction
* A significantly simpler code base
* Many bug fixes & other small improvements (Closed 62 out of 66 GitHub issues)
Below are a few notes on the upgrade process itself:
The first thing you will run into is that the old `Client` class is gone and
has been replaced with a less ambitious `Connection` class. So instead of
`mysql.createClient()`, you now have to:
```js
var mysql = require('mysql');
var connection = mysql.createConnection({
host : 'localhost',
user : 'me',
password : 'secret',
});
connection.query('SELECT 1', function(err, rows) {
if (err) throw err;
console.log('Query result: ', rows);
});
connection.end();
```
The new `Connection` class does not try to handle re-connects, please study the
`Server disconnects` section in the new Readme.
Other than that, the interface has stayed very similar. Here are a few things
to check out so:
* BIGINT's are now cast into strings
* Binary data is now cast to buffers
* The `'row'` event on the `Query` object is now called `'result'` and will
also be emitted for queries that produce an OK/Error response.
* Error handling is consistently defined now, check the Readme
* Escaping has become more powerful which may break your code if you are
currently using objects to fill query placeholders.
* Connections can now be established explicitly again, so you may wish to do so
if you want to handle connection errors specifically.
That should be most of it, if you run into anything else, please send a patch
or open an issue to improve this document.
## v0.9.6 (2012-03-12)
