SQL Execute

Rails
1

Hi,

I would like to execute a SQL statement and manipulate its
resultset…
My SQL wont return data that fits on any model, I just would like to
do something like this:

sql = <<-ENDS
SELECT
sum(a) AS F1,
min(b) AS F2
FROM
MyTable
ENDS

resultSet = ActiveRecord::Base.connection.execute(sql)
resultSet.each do |row|
logger.info "Field1: " + resultSet[‘F1’]
logger.info "Field2: " + resultSet[‘F2’]
end

I made this example up to show my idea, my real case is more
complicated, but I think I passed the idea here.

Thanks in advance

Use the select_all method. It returns an array of hashes in the way you
would expect.
