Question

In Rails v2.3 , Ruby 1.8, if I run a sql statement with following code in my model class:

ActiveRecord::Base.connection.execute("select count(*) from cars;")

How can I show the query result in server console?

I tried :

rslt = ActiveRecord::Base.connection.execute("select count(*) from cars;")
p rslt

but it only returns me “MySQL result object” on the server console, not the exact result.

There are couple ways to get mysql “answer” from your query. you can call each and it will iterate over each row (just one row – count in your case). take a look at mysql gem docs to see other available methods such as each_hash and all_hashes.

rslt = ActiveRecord::Base.connection.execute("select count(*) from cars;")
rslt.each {|mysql_result| puts mysql_result}
