Question

I am developing a Rails app.

after I execute a sql command like following:

sql="select * from some_tbl;"
rslt = ActiveRecord::Base.connection.execute(sql)

how can I get sliced results from rslt?

I mean for example, if the rslt.size is 200, I would like to get 20 results start from the 5th one (which like the array operation arr[5,20]), how to do it?

Answer 1

Try to convert rslt to Array:

...
rslt.to_a[5,20]
