func (s *Storage) Set(key string, val []byte, exp time.Duration) error
func (s *Storage) Delete(key string) error

```
### Installation
MSSQL is tested on the 2 last [Go versions](https://golang.org/dl/) with support for modules. So make sure to initialize one first if you didn't do that yet:
```bash
go mod init github.com/<user>/<repo>
```
And then install the mssql implementation:
```bash
go get github.com/gofiber/storage/mssql/v2
```

### Examples
Import the storage package.
```go
import "github.com/gofiber/storage/mssql/v2"
```

You can use the following possibilities to create a storage:
```go
// Initialize default config
store := mssql.New()

// Initialize custom config
store := mssql.New(mssql.Config{
	Host:            "127.0.0.1",
	Port:            1433,
	Database:        "fiber",
	Table:           "fiber_storage",
	Reset:           false,
	GCInterval:      10 * time.Second,
	SslMode:         "disable",
})

// Initialize custom config using connection string
store := mssql.New(mssql.Config{
	ConnectionURI:   "sqlserver://user:password@localhost:1433?database=fiber"
	Reset:           false,
	GCInterval:      10 * time.Second,
})
```

### Config
