```
`strict=true` enables a driver-side strict mode in which MySQL warnings are treated as errors. This mode should not be used in production as it may lead to data corruption in certain situations.
A server-side strict mode, which is safe for production use, can be set via the [`sql_mode`](https://dev.mysql.com/doc/refman/5.7/en/sql-mode.html) system variable.
`rejectReadOnly=true` causes the driver to reject read-only connections. 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: <name>
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.
By default MySQL also treats notes as warnings. Use [`sql_notes=false`](http://dev.mysql.com/doc/refman/5.7/en/server-system-variables.html#sysvar_sql_notes) to ignore notes.
##### `timeout`

### Connection pool and timeouts
The connection pool is managed by Go's database/sql package. 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

### `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 programm.
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](http://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 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`](http://godoc.org/github.com/go-sql-driver/mysql#NullTime) type as the scan destination, which works with both `time.Time` and `string` / `[]byte`.
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`.

## Overview
* Full-Featured ORM (almost)
* Associations (Has One, Has Many, Belongs To, Many To Many, Polymorphism)
* Hooks (Before/After Create/Save/Update/Delete/Find)
* Preloading (eager loading)
* Transactions
* Composite Primary Key
* SQL Builder
* Auto Migrations
* Logger
* Extendable, write Plugins based on GORM callbacks
* Every feature comes with tests
* Developer Friendly
## Getting Started
* GORM Guides [http://gorm.io](http://gorm.io)
