It just means that testOnBorrow does nothing if validationQuery is set to "". For mysql "select 1" is sufficient and saves a call to now(). The Oracle equivalent would be "select 1 from dual" I just checked the dbcp source code and the criteria for the validation query is that it must return at least 1 row with no exceptions being thrown.
