The ExecuteQuery method is executing a sql statement and not an oql statement. The sql syntax you provided is not correct for oracle databases, since the 'as' keyword is not supported.
Please try the following statement instead.
"select m.NOM from IM_MALAD m where m.NOM = 'BERNIER' and m.SEXE = 'M'"
I hope this information is helpful for you.
Feel free to ask if you have any other question.
All the best,
