type Detector ¶

type Detector struct{}

Detector resolves columns for shape-generated views.

Rules:

• schema field order is canonical order
• wildcard SQL always performs DB discovery
• newly discovered columns are appended at the end
• matched columns keep schema order but refresh metadata from DB

func New() *Detector

func (d *Detector) Resolve(ctx context.Context, resource *view.Resource, aView *view.View) (view.Columns, error)
