## Version 1.8.1 (2024-03-26)
Bugfixes:
- fix race condition when context is canceled in [#1562](https://github.com/go-sql-driver/mysql/pull/1562) and [#1570](https://github.com/go-sql-driver/mysql/pull/1570)
## Version 1.8.0 (2024-03-09)
Major Changes:
- Use `SET NAMES charset COLLATE collation`. by @methane in [#1437](https://github.com/go-sql-driver/mysql/pull/1437)
- Older go-mysql-driver used `collation_id` in the handshake packet. But it caused collation mismatch in some situation.
- If you don't specify charset nor collation, go-mysql-driver sends `SET NAMES utf8mb4` for new connection. This uses server's default collation for utf8mb4.
- If you specify charset, go-mysql-driver sends `SET NAMES <charset>`. This uses the server's default collation for `<charset>`.
- If you specify collation and/or charset, go-mysql-driver sends `SET NAMES charset COLLATE collation`.
- PathEscape dbname in DSN. by @methane in [#1432](https://github.com/go-sql-driver/mysql/pull/1432)
- This is backward incompatible in rare case. Check your DSN.
- Drop Go 1.13-17 support by @methane in [#1420](https://github.com/go-sql-driver/mysql/pull/1420)
- Use Go 1.18+
- Parse numbers on text protocol too by @methane in [#1452](https://github.com/go-sql-driver/mysql/pull/1452)
- When text protocol is used, go-mysql-driver passed bare `[]byte` to database/sql for avoid unnecessary allocation and conversion.
- If user specified `*any` to `Scan()`, database/sql passed the `[]byte` into the target variable.
- This confused users because most user doesn't know when text/binary protocol used.
- go-mysql-driver 1.8 converts integer/float values into int64/double even in text protocol. This doesn't increase allocation compared to `[]byte` and conversion cost is negatable.
- New options start using the Functional Option Pattern to avoid increasing technical debt in the Config object. Future version may introduce Functional Option for existing options, but not for now.
- Make TimeTruncate functional option by @methane in [1552](https://github.com/go-sql-driver/mysql/pull/1552)
- Add BeforeConnect callback to configuration object by @ItalyPaleAle in [#1469](https://github.com/go-sql-driver/mysql/pull/1469)
Other changes:
- Adding DeregisterDialContext to prevent memory leaks with dialers we don't need anymore by @jypelle in https://github.com/go-sql-driver/mysql/pull/1422
- Make logger configurable per connection by @frozenbonito in https://github.com/go-sql-driver/mysql/pull/1408
- Fix ColumnType.DatabaseTypeName for mediumint unsigned by @evanelias in https://github.com/go-sql-driver/mysql/pull/1428
- Add connection attributes by @Daemonxiao in https://github.com/go-sql-driver/mysql/pull/1389
- Stop `ColumnTypeScanType()` from returning `sql.RawBytes` by @methane in https://github.com/go-sql-driver/mysql/pull/1424
- Exec() now provides access to status of multiple statements. by @mherr-google in https://github.com/go-sql-driver/mysql/pull/1309
- Allow to change (or disable) the default driver name for registration by @dolmen in https://github.com/go-sql-driver/mysql/pull/1499
- Add default connection attribute '_server_host' by @oblitorum in https://github.com/go-sql-driver/mysql/pull/1506
- QueryUnescape DSN ConnectionAttribute value by @zhangyangyu in https://github.com/go-sql-driver/mysql/pull/1470

_Go MySQL Driver_ is an implementation of Go's `database/sql/driver` interface. You only need to import the driver and can use the full [`database/sql`](https://golang.org/pkg/database/sql/) API then.
Use `mysql` as `driverName` and a valid [DSN](#dsn-data-source-name) as `dataSourceName`:
```go
import "database/sql"
import _ "github.com/go-sql-driver/mysql"
import (
"database/sql"
"time"
_ "github.com/go-sql-driver/mysql"
)
// ...
db, err := sql.Open("mysql", "user:password@/dbname")
if err != nil {
panic(err)
}
// See "Important settings" section.
db.SetConnMaxLifetime(time.Minute * 3)
db.SetMaxOpenConns(10)
db.SetMaxIdleConns(10)
```
[Examples are available in our Wiki](https://github.com/go-sql-driver/mysql/wiki/Examples "Go-MySQL-Driver Examples").
### Important settings
`db.SetConnMaxLifetime()` is required to ensure connections are closed by the driver safely before connection is closed by MySQL server, OS, or other middlewares. Since some middlewares close idle connections by 5 minutes, we recommend timeout shorter than 5 minutes. This setting helps load balancing and changing system variables too.
`db.SetMaxOpenConns()` is highly recommended to limit the number of connection used by the application. There is no recommended limit number because it depends on application and MySQL server.
`db.SetMaxIdleConns()` is recommended to be set same to `db.SetMaxOpenConns()`. When it is smaller than `SetMaxOpenConns()`, connections can be opened and closed much more frequently than you expect. Idle connections can be closed by the `db.SetConnMaxLifetime()`. If you want to close idle connections more rapidly, you can use `db.SetConnMaxIdleTime()` since Go 1.15.

### `time.Time` support
The default internal output type of MySQL `DATE` and `DATETIME` values is `[]byte` which allows you to scan the value into a `[]byte`, `string` or `sql.RawBytes` variable in your program.
However, many want to scan MySQL `DATE` and `DATETIME` values into `time.Time` variables, which is the logical opposite in Go to `DATE` and `DATETIME` in MySQL. You can do that by changing the internal output type from `[]byte` to `time.Time` with the DSN parameter `parseTime=true`. You can set the default [`time.Time` location](https://golang.org/pkg/time/#Location) with the `loc` DSN parameter.
However, many want to scan MySQL `DATE` and `DATETIME` values into `time.Time` variables, which is the logical equivalent in Go to `DATE` and `DATETIME` in MySQL.

You can set the default [`time.Time` location](https://golang.org/pkg/time/#Location) with the `loc` DSN parameter.
**Caution:** As of Go 1.1, this makes `time.Time` the only variable type you can scan `DATE` and `DATETIME` values into. This breaks for example [`sql.RawBytes` support](https://github.com/go-sql-driver/mysql/wiki/Examples#rawbytes).
Alternatively you can use the [`NullTime`](https://godoc.org/github.com/go-sql-driver/mysql#NullTime) type as the scan destination, which works with both `time.Time` and `string` / `[]byte`.
### Unicode support
Since version 1.1 Go-MySQL-Driver automatically uses the collation `utf8_general_ci` by default.
Since version 1.5 Go-MySQL-Driver automatically uses the collation ` utf8mb4_general_ci` by default.
Other collations / charsets can be set using the [`collation`](#collation) DSN parameter.
Other charsets / collations can be set using the [`charset`](#charset) or [`collation`](#collation) DSN parameter.
Version 1.0 of the driver recommended adding `&charset=utf8` (alias for `SET NAMES utf8`) to the DSN to enable proper UTF-8 support. This is not necessary anymore. The [`collation`](#collation) parameter should be preferred to set another collation / charset than the default.
- When only the `charset` is specified, the `SET NAMES <charset>` query is sent and the server's default collation is used.
- When both the `charset` and `collation` are specified, the `SET NAMES <charset> COLLATE <collation>` query is sent.
- When only the `collation` is specified, the collation is specified in the protocol handshake and the `SET NAMES` query is not sent. This can save one roundtrip, but note that the server may ignore the specified collation silently and use the server's default charset/collation instead.
