Functions

func Create

func Create(ctx context.Context, s *Schema, tables []*schema.Table, opts ...schema.MigrateOption) error

Create creates all table resources using the given schema driver.

Types

type Schema

type Schema struct {
	// contains filtered or unexported fields
}

Schema is the API for creating, migrating and dropping a schema.

func NewSchema

func NewSchema(drv dialect.Driver) *Schema

NewSchema creates a new schema client.

func (*Schema) Create

func (s *Schema) Create(ctx context.Context, opts ...schema.MigrateOption) error

Create creates all schema resources.

func (*Schema) WriteTo

func (s *Schema) WriteTo(ctx context.Context, w io.Writer, opts ...schema.MigrateOption) error

WriteTo writes the schema changes to w instead of running them against the database.

if err := client.Schema.WriteTo(context.Background(), os.Stdout); err != nil {
	log.Fatal(err)
}
