MySQL: Pourquoi ai-je cet avertissement?

Question

J'appelle la procédure stockée ci-dessous et j'obtiens cet avertissement, est-ce un fausse positif ou est-ce que ma requête est-elle dangereuse?

1 queries executed, 1 success, 0 errors, 1 warnings

Query: call User_Signup('lee3@gmail.com', 'password', 'Lee', 'Brooks', null, null, null, null)

1 row(s) affected, 1 warning(s)

Execution Time : 0.042 sec
Transfer Time  : 0.093 sec
Total Time     : 0.136 sec

Note Code : 1592
Unsafe statement written to the binary log using statement format since BINLOG_FORMAT = STATEMENT. Statements writing to a table with an auto-increment column after selecting from another table are unsafe because the order in which rows are retrieved determines what (if any) rows will be written. This order cannot be predicted and may differ on master and the slave.

Voici l'appel:

CALL User_Signup('lee3@gmail.com', 'password', 'Lee', 'Brooks', NULL, NULL, NULL, NULL);

Voici la procédure stockée:
