More than one sentence in accounting_stop_query

Hi, I use Freeradius with Mysql. I want to make 2 SQL consultations in the accounting_stop_query field. (in sql.conf) I proved all the possible alternatives, but it does not work, like: accounting_stop_query field = "sentence1, sentence2" or accounting_stop_query field = "sentence1; sentence2" or accounting_stop_query field = "sentence1" accounting_stop_query field = "sentence2" somebody knows how to do it?
