Cómo actualizar todas las filas con el valor de la primera fila

Me gustaría actualizar un campo en una tabla para que todas las filas tengan el mismo valor que la primera fila. Pensé que sería simple:

 UPDATE my_table SET my_field = (SELECT my_field FROM my_table ORDER BY id LIMIT 1);

Pero a MySql no le gusta eso.

 ERROR 1093 (HY000): You can't specify target table 'my_table' for update in FROM clause

Puede anidar la subconsulta dentro de otra:

 UPDATE my_table SET my_field = (SELECT my_field FROM (SELECT my_field FROM my_table ORDER BY id LIMIT 1) t);
