Study the database table named weather given below, where record$\_$number is the primary key:

What is the result of the following code?

$query $=$ 'INSERT INTO weather $($record$\_$number, place, date, rainfall$)$

VALUES $($:rec$\_$no$,$ :place, :date, :rainfall$)\text{'}$;

$rec$\_$no $=5$;

$place $=$ 'Roodepoort';

$date $=\text{'}2019-12-27\text{'}$;

$rainfall $=25$;

$statement $=$ $db$->$prepare$($$query$)$;

$statement $->$bindValue$(\text{'}$:rec$\_$no$\text{'},$ $rec$\_$no$)$;

$statement $->$bindValue$(\text{'}$:place', $place$)$;

$statement $->$bindValue$(\text{'}$:date', $date$)$;

$statement $->$bindValue$(\text{'}$:rainfall', $rainfall$)$;

$statement$->$execute$()$;

$statement$->$closeCursor$()$;

Assume that a PDO object named $db is correctly connected to the relevant database.
