Question

I am converting my PHP/mySQL code to PDO but I am having some difficulties. Below I have added the exact code I am using with example for better understanding. My goal is to show the name from the DB that their time compared with the one on input differ by 2 hours.

this is the code

SELECT * FROM events WHERE TIMESTAMPDIFF( HOUR , TIME, :input ) < 2

this is my database

name                        date
3D Brave                    2012-07-21 17:00:00
Bol Bachchan                2012-07-21 18:00:00
A Royal Affair              2012-07-21 19:00:00
Not Suitable For Children   2012-07-21 23:00:00

If the $input is 2012-07-20 18:00 or 2012-07-20 20:00 then I get all the results as below, but it should show only those that have a difference 2 hours

Answer 1

Well, you’re querying the difference from the column TIME, but in the table schema, it’s called date.

Corrected query:

SELECT *
  FROM events 
  WHERE ABS(TIMESTAMPDIFF( HOUR , `date`, "2012-07-21 18:00:00")) < 2;

What I did:

• Changed column name to date
• Added ABS() function (so it now looks both forwards and backwards).

The result of that query.
