I had three data with where gender=female. I was trying to call those data with limit and offset (Since in future there might be more than 1000 data). SELECT * FROM `users` WHERE `gender`='Female'...

- I had three data with where `gender=female`. I was trying to call those data with limit and offset (Since in future there might be more than 1000 data).
- ```SQL
- SELECT * FROM `users` WHERE `gender`='Female' ORDER BY `birth_year` DESC LIMIT 10 OFFSET 0
- ```
- Here's my data (only adding three columns and all of their gender is female) :
- | id | username | birth_year
- |- | - | - |
- | 3 | Is | (null) |
- | 4 | Kar | (null) |
- | 5 | girlfriend | 2005|
- When I execute the above, I get three data (id=5,4,3). When I change the offset to 1 I get (id=4,3). For offset=2 (id=4). When I set offset=3,4,5,6..... I get nothing. But I was supposed to get nothing for id=1 and 2 also. (Here's [the guide](https://www.sqltutorial.org/sql-limit/) I followed, [W3SCHOOLS](https://www.w3schools.com/php/php_mysql_select_limit.asp) guide says the same also). But when I set LIMIT=1, it works correctly. It doesn't even work for LIMIT=2. I also tried by removing ORDER BY ...... (I am using MySQL (Lampp) in Xubuntu)

Why OFFSET isn't working the way it is expected?
