The reason for your syntax error is that you need to use END IF; after each IF/THEN. See examples in the manual: https://dev.mysql.com/doc/refman/8.0/en/if.html

I think you don’t need to write this function at all. Instead, you could use MySQL’s DATE_FORMAT() function. It supports locale-aware names for days of the week.

mysql> set lc_time_names = 'es_ES';

mysql> select date_format(curdate(), '%a - %d') as diaCompleto;

| diaCompleto |

| sáb - 19    |
