php - Joining a count query mysql for performance -


has been searched but can not find the answer that is in line with the exact requirements for this mysql query.

I have the following questions on several tables to generate "statistics" for a table:

  SELECT COUNT (id) as `mod_ **` Publish with 'WHERE'; = '1'; Choose `mod _ ***` where 'published' = '1' by counting as COUNT (id); Select COUNT as Count (Mode) from `Mode _ ****`; Select number (ID) as counting from `id_ _ *****`;  

Very easy to do sometimes sometimes calculates rows based on a situation.

However, in search of performance I would love to receive it in 1 query to save resources.

I am using php to get this data with the simplest mysql_fetch_assoc and retrieving $ res [count] If I make it a difference (the supporters are not guaranteed, even plain old mice).

Overhead to send a query and receive a single-line response


If you do not yet have a INDEX index

published columns will speed up the first two questions.
