[Solved] Cant solve this : Invalid parameter number: number of bound variables does not match [closed]

by


Missing Comma (,) in this line. Due to which bound variables were not matching.

 $req = $pdo->prepare("INSERT INTO t_events_changes ....
              Values (... :new_standby_start:old_standby_end, ... )");
                                           ^ here missing comma

Change it to,

:new_standby_start,:old_standby_end,
