### 2. Set bucket WORM configuration

WORM on a bucket is enabled by setting object lock configuration. This configuration is applied to all the objects in the bucket. Below is an example to set `Governance` mode and one day retention time on `mybucket`.

```sh

package clause_test

import (
	"fmt"

	"gorm.io/gorm/clause"

		Vars    []interface{}

				Limit:  &limit10,
				Offset: 20,
			}},
