Whether to convert smallint to boolean arguments for this dataset. Defaults to the IBMDB module setting.
# File lib/sequel/adapters/ibmdb.rb, line 382 def convert_smallint_to_bool opts.has_key?(:convert_smallint_to_bool) ? opts[:convert_smallint_to_bool] : IBMDB.convert_smallint_to_bool end
convert_smallint_to_bool=(v)

Override the default Sequel::IBMDB.convert_smallint_to_bool setting for this dataset.
# File lib/sequel/adapters/ibmdb.rb, line 376 def convert_smallint_to_bool=(v) @opts[:convert_smallint_to_bool] = v end
fetch_rows(sql) { |row| ... }

Fetch the rows from the database and yield plain hashes.

Return a cloned dataset with the #convert_smallint_to_bool option set.
