Function Rebind

bind.go:60–90

FIXME: this should be able to be tolerant of escaped ?'s in queries without losing much speed, and should be to avoid confusion. Rebind a query from the default bindtype (QUESTION) to the target bindtype.

(bindType int, query string)

// Rebind a query from the default bindtype (QUESTION) to the target bindtype.
func Rebind(bindType int, query string) string {
	switch bindType {
	case QUESTION, UNKNOWN:
		return query
	}

	// Add space enough for 10 params before we have to allocate
	rqb := make([]byte, 0, len(query)+10)

	var i, j int

	for i = strings.Index(query, "?"); i != -1; i = strings.Index(query, "?") {
		rqb = append(rqb, query[:i]...)

		switch bindType {
		case DOLLAR:
			rqb = append(rqb, '$')
		case NAMED:
			rqb = append(rqb, ':', 'a', 'r', 'g')
		case AT:
			rqb = append(rqb, '@', 'p')
		}

		j++
		rqb = strconv.AppendInt(rqb, int64(j), 10)

		query = query[i+1:]
	}

	return string(append(rqb, query...))
}

// Experimental implementation of Rebind which uses a bytes.Buffer.  The code is
// much simpler and should be more resistant to odd unicode, but it is twice as
