How to get the number of rows that would have been returned?

Question

In the following query:

SELECT column1,column2 FROM table1 ORDER BY column1 LIMIT 0,30

How can I find out the number of rows that would have been returned were it not for the LIMIT?

Edit: I am looking for a way to work this into the query above and not do a separate query. (If possible.)

Answer 1

SELECT COUNT(*) FROM table1;

Answer 2

If you do this query:

 SELECT SQL_CALC_FOUND_ROWS column1,column2 FROM table1 ORDER BY column1 LIMIT 0,30;

You can retrieve the number of rows the previous SELECT found with

select FOUND_ROWS();

If you really must do it with one query, you'll have to use a sub select (which'll have the disatvantage of adding an extra column to every row..)

 SELECT column1,column2,s.total FROM table1,
    (select count(*) as total from table1) s 
 ORDER BY column1 LIMIT 0,30;
