Multiple select statements in Single query

Question

I am generating a report in php (mysql),

ex:

`select count(id) as tot_user from user_table
 select count(id) as tot_cat from cat_table
 select count(         


        

Answer 1

If you use MyISAM tables, the fastest way is querying directly the stats:

select table_name, table_rows 
     from information_schema.tables 
where 
     table_schema='databasename' and 
     table_name in ('user_table','cat_table','course_table')

If you have InnoDB you have to query with count() as the reported value in information_schema.tables is wrong.
