Sending passwords in clear text may be a security problem in some configurations. To avoid problems if there is any possibility that the password would be intercepted, clients should connect to MySQL Server using a method that protects the password. Possibilities include [TLS / SSL](#tls), IPsec, or a private network. + +##### `allowNativePasswords` + +``` +Type: bool +Valid Values: true, false +Default: true +``` +`allowNativePasswords=false` disallows the usage of MySQL native password method. + +##### `allowOldPasswords` + +``` +Type: bool +Valid Values: true, false +Default: false +``` +`allowOldPasswords=true` allows the usage of the insecure old password method.

This enables for example support for `utf8mb4` ([introduced in MySQL 5.5.3](http://dev.mysql.com/doc/refman/5.5/en/charset-unicode-utf8mb4.html)) with fallback to `utf8` for older servers (`charset=utf8mb4,utf8`). + +Usage of the `charset` parameter is discouraged because it issues additional queries to the server. +Unless you need the fallback behavior, please use `collation` instead. + +##### `collation` + +``` +Type: string +Valid Values: +Default: utf8_general_ci +``` + +Sets the collation used for client-server interaction on connection. In contrast to `charset`, `collation` does not issue additional queries.

The value must be a string of decimal numbers, each with optional fraction and a unit suffix ( *"ms"*, *"s"*, *"m"*, *"h"* ), such as *"30s"*, *"0.5m"* or *"1m30s"*. To set a server side timeout, use the parameter [`wait_timeout`](http://dev.mysql.com/doc/refman/5.6/en/server-system-variables.html#sysvar_wait_timeout). - * `charset`: Sets the charset used for client-server interaction ("SET NAMES `value`"). If multiple charsets are set (separated by a comma), the following charset is used if setting the charset failes. This enables support for `utf8mb4` ([introduced in MySQL 5.5.3](http://dev.mysql.com/doc/refman/5.5/en/charset-unicode-utf8mb4.html)) with fallback to `utf8` for older servers (`charset=utf8mb4,utf8`). - * `allowAllFiles`: `allowAllFiles=true` disables the file Whitelist for `LOAD DATA LOCAL INFILE` and allows *all* files. *Might be insecure!* -All other parameters are interpreted as system variables: - * `autocommit`: *"SET autocommit=`value`"* - * `time_zone`: *"SET time_zone=`value`"* - * `tx_isolation`: *"SET [tx_isolation](https://dev.mysql.com/doc/refman/5.5/en/server-system-variables.html#sysvar_tx_isolation)=`value`"* - * `param`: *"SET `param`=`value`"* +##### `readTimeout` + +``` +Type: duration +Default: 0 +``` + +I/O read timeout.

This +is for a possible race condition during an automatic failover, where the mysql +client gets connected to a read-only replica after the failover. + +Note that this should be a fairly rare case, as an automatic failover normally +happens when the primary is down, and the race condition shouldn't happen +unless it comes back up online as soon as the failover is kicked off. On the +other hand, when this happens, a MySQL application can get stuck on a +read-only connection until restarted. It is however fairly easy to reproduce, +for example, using a manual failover on AWS Aurora's MySQL-compatible cluster. + +If you are not relying on read-only transactions to reject writes that aren't +supposed to happen, setting this on some MySQL providers (such as AWS Aurora) +is safer for failovers. + +Note that ERROR 1290 can be returned for a `read-only` server and this option will +cause a retry for that error. However the same error number is used for some +other cases. You should ensure your application will never cause an ERROR 1290 +except for `read-only` mode when enabling this option. + + +##### `serverPubKey` + +``` +Type: string +Valid Values: +Default: none +``` + +Server public keys can be registered with [`mysql.RegisterServerPubKey`](https://godoc.org/github.com/go-sql-driver/mysql#RegisterServerPubKey), which can then be used by the assigned name in the DSN. +Public keys are used to transmit encrypted data, e.g. for authentication. +If the server's public key is known, it should be set manually to avoid expensive and potentially insecure transmissions of the public key from the server to the client each time it is required. + + +##### `timeout` + +``` +Type: duration +Default: OS default +``` + +Timeout for establishing connections, aka dial timeout. The value must be a decimal number with a unit suffix (*"ms"*, *"s"*, *"m"*, *"h"*), such as *"30s"*, *"0.5m"* or *"1m30s"*. + + +##### `tls` + +``` +Type: bool / string +Valid Values: true, false, skip-verify, +Default: false +``` + +`tls=true` enables TLS / SSL encrypted connection to the server.

For details on how to configure the size of the pool and how long connections stay in the pool see `*DB.SetMaxOpenConns`, `*DB.SetMaxIdleConns`, and `*DB.SetConnMaxLifetime` in the [database/sql documentation](https://golang.org/pkg/database/sql/). The read, write, and dial timeouts for each individual connection are configured with the DSN parameters [`readTimeout`](#readtimeout), [`writeTimeout`](#writetimeout), and [`timeout`](#timeout), respectively. + +## `ColumnType` Support +This driver supports the [`ColumnType` interface](https://golang.org/pkg/database/sql/#ColumnType) introduced in Go 1.8, with the exception of [`ColumnType.Length()`](https://golang.org/pkg/database/sql/#ColumnType.Length), which is currently not supported. + +## `context.Context` Support +Go 1.8 added `database/sql` support for `context.Context`. This driver supports query timeouts and cancellation via contexts. +See [context support in the database/sql package](https://golang.org/doc/go1.8#database_sql) for more details. + + ### `LOAD DATA LOCAL INFILE` support For this feature you need direct access to the package. Therefore you must change the import path (no `_`): ```go import "github.com/go-sql-driver/mysql" ``` -Files must be whitelisted by registering them with `mysql.RegisterLocalFile(filepath)` (recommended) or the Whitelist check must be deactivated by using the DSN parameter `allowAllFiles=true` (might be insecure). +Files must be whitelisted by registering them with `mysql.RegisterLocalFile(filepath)` (recommended) or the Whitelist check must be deactivated by using the DSN parameter `allowAllFiles=true` ([*Might be insecure!*](http://dev.mysql.com/doc/refman/5.7/en/load-data-local.html)). + +To use a `io.Reader` a handler function must be registered with `mysql.RegisterReaderHandler(name, handler)` which returns a `io.Reader` or `io.ReadCloser`. The Reader is available with the filepath `Reader::` then. Choose different names for different handlers and `DeregisterReaderHandler` when you don't need it anymore. + +See the [godoc of Go-MySQL-Driver](https://godoc.org/github.com/go-sql-driver/mysql "golang mysql driver documentation") for details. + -To use a `io.Reader` a handler function must be registered with `mysql.RegisterReaderHandler(name, handler)` which returns a `io.Reader` or `io.ReadCloser`. The Reader is available with the filepath `Reader::` then. +### `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. -See also the [godoc of Go-MySQL-Driver](http://godoc.org/github.com/go-sql-driver/mysql "golang mysql driver documentation") +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. +**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. + +Other collations / charsets can be set using the [`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. + +See http://dev.mysql.com/doc/refman/5.7/en/charset-unicode.html for more details on MySQL's Unicode support. ## Testing / Development -To run the driver tests you may need to adjust the configuration.
