    Description

      I got a wrong result in two different machines

      I tried after uploading the prueba.sql file the following query:

      SELECT * FROM agentes WHERE id in (select distinct id_agente from otra) ORDER BY nombre ASC;

      I get:

      +----+--------+
      		 
      | id | nombre |
      		 
      +----+--------+
      		 
      |  1 | row 1  |
      		 
      |  1 | row 1  |
      		 
      |  1 | row 1  |
      		 
      |  2 | row 2  |
      		 
      |  2 | row 2  |
      		 
      |  3 | row 3  |
      		 
      +----+--------+

      but if I remove the order by clause I get:

      +----+--------+
      		 
      | id | nombre |
      		 
      +----+--------+
      		 
      |  1 | row 1  |
      		 
      |  2 | row 2  |
      		 
      |  3 | row 3  |
      		 
      +----+--------+

      I don't put much more information i think it's very reproductible since i got it in two different machines.
