Solution:

You can achieve this with PHP -

$val = explode(" ", "65 67 68 69 70");

$all = range($val[0], end($val)); // get all values between lowest & largest

print_r(array_diff($all, $val)); // check difference
Copy code

Output -

Array
(
    [1] => 66
)
Copy code

Solution:

If you are sure that this is not a sampling error. Perhaps you should index the data again. in MySQL it is done like this

set @ROW = 0;
UPDATE `ont` SET `olt_id` = @ROW := @ROW+1 ORDER BY `olt_id` ASC;
Copy code
