How do I use ROW_NUMBER()?

Question

I want to use the ROW_NUMBER() to get...

1. To get the max(ROW_NUMBER()) --> Or i guess this would also be the count of all rows

Answer 1

You can use Row_Number for limit query result.

Example:

SELECT * FROM (
    select row_number() OVER (order by createtime desc) AS ROWINDEX,* 
    from TABLENAME ) TB
WHERE TB.ROWINDEX between 0 and 10

-- With above query, I will get PAGE 1 of results from TABLENAME.
