php - Why is sprintf returning false here? -


i trying work out why sprintf returning false here. can shed light?

sprintf( "select dog_name, date_format(meet_date, '%d %m %y') date, track_name, race_name, race_stakes, race_class, race_stakes, result_place, result_box, winner_name, winner_id, result_dog_trainer, race_distance                                 dog                                 join result using( dog_id )                                 join race r using( race_id )                                 join meet using( meet_id )                                 join track using( track_id )                                  join (select dog_name winner_name, dog_id winner_id, race_id                                          dog                                         join result using( dog_id )                                         result_place = 1                                                                             ) t0 on t0.race_id = r.race_id                                 dog_id = %d                                     order meet_date desc                                 limit %d", 12345, 50);

you have few arguments. if use sprintf() date_format, should use 2 % this:

sprintf( "select dog_name, date_format(meet_date, '%%d %%m %%y') date, track_name, race_name, race_stakes, race_class, race_stakes, result_place, result_box, winner_name, winner_id, result_dog_trainer, race_distance                                 dog                                 join result using( dog_id )                                 join race r using( race_id )                                 join meet using( meet_id )                                 join track using( track_id )                                  join (select dog_name winner_name, dog_id winner_id, race_id                                          dog                                         join result using( dog_id )                                         result_place = 1                                                                             ) t0 on t0.race_id = r.race_id                                 dog_id = %d                                     order meet_date desc                                 limit %d", 12345, 50);
