Question

Lets say we a table t1 as

>desc t1;
      id     int 
     name    varchar(30)

and

>select count(*) from t1;
      count(*)
       10

Is it possible to fetch the result as

id   name   count
1    abc     10
2    def     10
.     .      .
.     .      .
.     .      .

Where the actual result columns id name and the count of the result query count are in the same resultset. Is it possible that way?
The basic idea is to fetch the result row count along with the result, instead of having to query the database for the count separately. Even sub queries are also fine.

Thank you.

Yes, this is possible. It’s also quite efficient due to the way MySQL optimizes stuff

  SELECT t.*, 
         (select count(*) from t1) as count
    FROM t1 t
