Answer 1

DATEADD and GETDATE() exist in SQL Server.

In MySQL, your conditions should be:

WHERE `datetime` > DATE_ADD(NOW(), INTERVAL -1 HOUR)

While date = '$todate' condition is redundant and should be removed.

Here's a documentation in MySQL DateTime.

Answer 2

Hi you can use DATE_SUB function for fetch last one hour data. I edited your code below -

SELECT * FROM `user_otp` 
WHERE `date` = '$todate'
AND datetime >= DATE_SUB(NOW(),INTERVAL 1 HOUR);

Answer 3

Use DATE_SUB and NOW() functions in query

SELECT count(*) as lasthour_count 
FROM user_otp 
WHERE datetime >= DATE_SUB(NOW(),INTERVAL 1 HOUR);

Answer 4

datetime>=DATE_ADD(NOW(), INTERVAL -1 HOUR);
datetime>= DATE_sub(NOW(), INTERVAL 1 HOUR);

These are the two options you can use
