Hello,

I have this code:

 28  dbh = get_connection
 29  res = dbh.exec("select max(ogc_fid) from #{table};")
 30  max =  res[0]
 31
 32  puts max

Which successfully prints the SQL query to the terminal. I want to be
able
to use the result later in the code, but I’m not really clear what type
of
object is being returned. How can I figure out what is being returned
and
convert it to an integer or a string?

Thanks,

i’m not quite sure what you’re asking, but i think exec returns rows.
