[FEATURE REQUEST] Common ORM queries

[LdDl]

Is your feature request related to a problem? Please describe.
Consider to make automatic code generation for such ORM queries as:

• Select all
• Select by PK
• Delete by PK
• Update by PK

Describe the solution you'd like and provide pseudocode examples if you can
Do it in same manner as main functionality is done (use of text/template).
E.g. Select:

const tmpSelect = `
func (dbConn *{{ .DataBase }}) Select{{ .StructName }}() ([]*{{ .StructName }}, error) {
	ctx := context.Background()
	model := []*{{ .StructName }}{}
	err := dbConn.NewSelect().
		Model(&model).
		Scan(ctx)
	return model, err
}`

Additional context
Prepare new branch(-es) and do some testing stuff in it

Base SELECT queries a.k.a. select * from t are done
