Function NamedQuery

named.go:441–447

NamedQuery binds a named query and then runs Query on the result using the provided Ext (sqlx.Tx, sqlx.Db). It works with both structs and with map[string]interface{} types.

(e Ext, query string, arg interface{})

// provided Ext (sqlx.Tx, sqlx.Db).  It works with both structs and with
// map[string]interface{} types.
func NamedQuery(e Ext, query string, arg interface{}) (*Rows, error) {
	q, args, err := bindNamedMapper(BindType(e.DriverName()), query, arg, mapperFor(e))
	if err != nil {
		return nil, err
	}
	return e.Queryx(q, args...)
}

// NamedExec uses BindStruct to get a query executable by the driver and
// then runs Exec on the result.  Returns an error from the binding
