php如何在分页中正确使用COUNT？

Question

This is how I have my current query setup:

SELECT * , (    
SELECT COUNT( * ) 
FROM paintings
WHERE id > 4000
) AS total
FROM paintings
WHERE id > 4000
LIMIT 0 , 30

Everything works fine if I separate the queries but if I keep it like this the pagination shows 1 id missing at the end of the page.

What would be a better option for selecting count that doesn't return on each row but for the whole?

Ex: this is what I currently get if I pass that in mysql:

> +--------+------------+--------+
> |  id    | title      | count  |
> +--------+------------+--------+
> | 2345   | water      |   25   | 
> | 2346   | bread      |   25   | 
> | 2347   | coke       |   25   | 
> | 2348   | beer       |   25   | 
> | 2349   | oranges    |   25   | 
> +--------+------------+--------+

Cheers!

Answer 1

There isn't, in way you did it. Just run 2 queries

SELECT 
     *
FROM 
     paintings
WHERE 
     id >4000
LIMIT 
     0 , 30;

SELECT 
    COUNT( * ) as total
FROM 
    paintings
WHERE 
    id >4000

Addition to what genesis posted. Still 2 queries but a little cleaner:

# The main query
SELECT SQL_CALC_FOUND_ROWS * FROM paintings
WHERE id > 4000
LIMIT 0, 30;

# And after get the total
SELECT FOUND_ROWS() AS total;
